signs of a bad lcd panel for sale

If your LCD television has ghosting, double images, dark on one side with slow refresh rates and symptoms similar to those shown in the pictures above there is a good chance we can fix it. You may find many Google sites and YouTube videos that show you how to "fix" this problem by applying pressure to the COF ribbons at the top of the LCD panel. That may work for a short time (or you may destroy the panel by trying to do it!) but in almost every case it will fail again in a month or two. It is sad that those posters never report back that the problem returned in such a short time. Tv Tech Electronics is part of a nationwide network of top technicians and through the combined efforts of that network we have developed a permanent repair for this problem. We have not had a single case where we performed this repair and the set came back again with the same problem. Sets smaller than 40 inches may not be repairable for this problem, but the larger sets often are. No other shop in the Kansas City area can repair this problem without replacing the panel at a cost that makes the repair uneconomical, give us a call at 816-756-0668 if your television displays this symptom.

However, if the digitizer or LCD is also damaged during a fall, that screen no longer carries value because it cannot be refurbished. Repair shops cannot sell broken LCDs to refurbishing companies; therefore, they cannot offset the cost of an LCD repair. That is why repair stores often charge a little extra if there is damage to the LCD or digitizer, to make up for that loss. Repair stores that don’t have an additional charge for an LCD repair typically inflate their glass repair price to make up for the loss from damaged LCDs. If they have one price, that means everyone is paying more to cover the cost of customers who have damaged LCDs and customers who only have cracked glass. This is why TCR separates the price of glass and LCD repairs for you! If you only have cracked glass, you only have to worry about paying to replace the cracked glass.

If your phone or tablet’s glass is shattered there will be cracks or chips on the screen itself. If it is just the glass that is damaged, the device may still function and you may be able to use it normally. If this is the case, it is likely that only the glass needs to be replaced. To prevent further damage to your device it is best to get it repaired quickly. For example, if liquids seep through the cracks it could cause permanent damage to the LCD.

Many people may continue to use their touchscreen with shattered glass and delay fixing the glass on their devices; however, if the touchscreen isn’t responsive, it could be a sign of more significant damage to the device’s digitizer which is integrated with the LCD screen.

A pixelated screen can indicate LCD damage. This would look like a patch of multicolored dots, a line or lines of discoloration, or a screen with rainbow colors. For many people, these colors are an easy way to know that their LCD is broken and that they should get it repaired.

Dropping your phone isn’t the only reason you’ll end up with a pixelated screen. Over time, your screen’s LCD may break down through regular use. This happens to other devices aside from your smartphone or tablet. Pixelation can happen to TVs and computers, too. People typically decide to buy a new device when this happens. Fortunately, with an LCD repair, you can fix the device without needing to replace it.

A black screen or black spots on your smartphone or tablet is an indication of a damaged LCD. Often with a bad LCD, a phone may still turn on and make noises, but there is no clear picture. This does not necessarily mean any other part of the phone is damaged and a simple screen replacement will get it functioning again. Sometimes it can mean a battery or other internal component is damaged. It is best to have a highly qualified phone repair technician diagnose what is wrong so the appropriate repair can be made.

Fortunately, your mobile device is fixable whether you cracked the glass or damaged the LCD. Stop by or call TCR: Triangle Cellular Repair at (919) 263-2699 for a free diagnostic and quick, affordable cell phone repair in Chapel Hill and surrounding areas. We’re always happy to help!

If your TV isn’t working properly, there are still a few things to consider before you give up on it. Generally, you’ll have a few warning signs that things are not exactly right.

Of course, sometimes, the TV is beyond repair and you should replace it instead. If the screen is broken or the TV doesn’t turn on no matter what you do (or if the sound stopped working completely), it’s time to check out a new set.

But, before it comes to that, let’s talk about TLC (Television Love & Care). If you start suspecting something’s not right and begin noticing imperfections on your

Few things are as off-putting as a dead pixel in the middle of your screen. Whether these dots are black or green, they’re incredibly inconvenient. Before jumping to the worst conclusion, however, you might want to make sure that it’s indeed a dead pixel, not a stuck one.

The difference is that stuck pixels usually happen because of a problem with a transistor; they often have different colours and are usually just simply out of place. If it is a dead pixel, then the TV should be sent for repairs, as, unfortunately, the issue is a difficult one to fix.

You may also want to check out if the problem is, indeed, with the screen. You’d be surprised at how often a small piece of dirt or dust can look like a dead pixel, so clean the screen before assuming you’re dealing with a big problem. Then use the screen to try games or connect it to your computer; if the pixel disappears on a specific media, then the issue could be the connection.

If the colours on your screen appear distorted, then your TV might be malfunctioning. Traditionally, this issue tends to occur gradually, meaning that you might not notice any difference at first. This is due to the common factor that one colour tends to weaken at a time; therefore, no obvious changes happen overnight.

Phantom colours are also a problem; if there are smears of bright colours in areas that should be completely white, you can be pretty sure that there’s a problem. Colour distortion is relatively simple to correct, so don’t despair! Contact a professional for advice.

If your screen starts to display bars and lines, this tends to indicate that there is an issue with a connector. This can occur when something magnetic has been placed near the TV and, in turn could mess with the picture quite considerably, even potentially de-magnetising the screen.

The issue can be due to cables that have become loose inside the screen as well, which is an easy fix, although it may require a professional because the TV may have to be opened.

This is often known as screen burn-in, although this definition is not entirely accurate. Screen burn-in is a more serious issue that involves the permanent degradation of the screen and occurs by leaving a static image on a screen for a long time.

Image retention, while frustrating, can be more easily fixed. Image retention occurs when the image sticks on the screen even when you change the channel or input different media – this tends to only appear for a few moments.

You may be able to do something about this by adjusting the levels of brightness and contrast on your TV and playing different types of content to see if the problem goes away. You can also enable your TV’s Pixel Shift feature; when this feature is turned on, images on the screen move a bit to vary the pixels used. Pixel Shift is often included in modern sets and might clean out the phantom image.

Another common problem is when the image displayed on the screen appears to be fuzzy or blurry. The smaller details tend to become lost and the quality of the picture displays poorly, very quickly taking your enjoyable movie experience to one of discomfort and stress.

This issue could occur if the signal received is a digitised standard (480p), as there’s a discrepancy between the resolution and the display. It’s also worth noting that the digital signal your TV receives can be affected by weather conditions as well, so the image can appear fuzzy and glitchy.

However, the good news is that, when this happens to modern televisions, there is a high chance of it being fixed, so you can still enjoy your TV for a long time.

If the TV is on but the picture is faded on some areas of the screen, it’ll be difficult for you to actually enjoy the content. You may try to ignore the stain-like mark but there is no denying that this will impact your experience. Faded spots are not that rare and can be accompanied by other serious issues, like your image fading to black after you’ve turned the TV on.

We offer repairs as well as a vast range of products so, if you find that your current TV is well past its sell-by date, be sure to browse our amazing

Televisions are an expensive purchase and they come with a maximum manufacturer’s warranty of 3 years, which is not enough. Plus, they are delicate and can start to show signs of failure if not properly maintained.

Since TV is used practically everyday for hours at a stretch, it is bound to have some issues over time. Some of these issues can be taken care of at home, while some serious issues may need help from a professional.

If you notice vertical lines on your TV screen, this is a serious issue and should not be neglected. This problem usually occurs if there’s a loose cable wiring, loose or faulty board or a damaged screen.

This is a common problem in TVs and is a sign that your TV panel is failing. But before you call an expert to check the TV, you could try following these steps and check if they work:

Turn off the TV and unplug the AC power cord (main lead). Keep it unplugged for 15 minutes and then switch on the TV to check if the issue has been resolved.

If it continues to show lines, you may mostly have to get the panel replaced and replacing the panel can be a costly affair, depending on the TV and its model. LED panels range anywhere between Rs 8,000 to Rs 85,000, while LCD panels range between Rs 6,000 to Rs 25,000.

Try increasing the volume to the fullest on your remote to check the sound. Ensure the TV input is correct, the TV is not on mute mode or no headphones are connected to the TV audio out jack on the side or front of your TV.

Also, check if all the cables connected into the back of your TV are proper and not loose. If there is still no sound, you will need to call a professional to open the TV and check the circuit board.

When the TV has speakers that work perfectly fine but it has no picture, there is mostly an issue with the back-lighting system or the power supply board, which will need to be replaced. In the case of an LCD TV, it works with the help of a backlight that is used to illuminate the picture on the screen. When the backlight begins to have problems, the screen turns blank.

To fix this issue, the backlight will have to be replaced by a TV expert. Another possible reason is that the backlight on the LCD TV which has a power inverter has failed. When this happens, you may need to replace the inverter or the capacitor.

This is again a common issue that most people complain about. While switching on the TV using the remote, if you notice that the light blinks but the screen is blank, this is an electric connection-related issue.

You could try disconnecting the power cord from the unit and wait for 10-15 minutes before you plug it back in. If this is just a simple electric connection problem, this should fix the issue. If the screen still doesn’t turn on, you will need to call a TV expert to resolve the problem.

There could be several reasons for a flickering TV screen, which is mostly a common issue with LED TVs.One of the major reasons for this is loose or defective cables that result in screen flicker.

In the case of HDMI (High Definition Multimedia Interface) cables, you will notice snow or flickering colors. With other analog cable types, you will mostly notice a sudden change in the brightness and color intensity.

Replacing the cable or checking its firmness should resolve the issue. Another possible reason that causes flickering could be other home appliances that draw enough power if they are on the same circuit.

In some cases, this may also happen because the main processor board is commanding the LED back-lights to turn off via the control line. To resolve this issue, you will need to get a new LED strip or processor board.

Be it a panel issue or a major technical issue with the TV, resolving these problems is a costly affair. It’s best not to ignore any of these signs and call an authorized TV expert before the problem worsens.

Buying a television is a long-term investment, so do not compromise. Buy one with a minimum of 4K resolution because new technology like OLED and HDR is pretty much only on 4K TVs.

Choosing a TV size plays an important role. If the screen size is too big for your room, you may notice the loss of clarity. To measure the distance between the sofa and the TV. If the viewing distance between the sofa and your TV is between 5 – 10 feet, a 40 – 42 inch TV should be perfect for your room. If the distance is less than 5 feet, a 32 inch should work best.

Don’t just ask for a smart TV. Most TVs available today are smart TVs with easy access to Netflix and other online apps. So do not be tricked into buying one just because its a smart TV.

When your LCD display has broken, needs replaced or simply needs a technology upgrade, and you have design/equipment elements to consider, you will want to look for a replacement part instead of replacing the unit.Problems may arise when you are sourcing the new panel from your original manufacturer.For example, by the time your panel has degraded, your LCD may be end of life, making it difficult to source;original manufacturers may be charging premium prices for their replacementLCD parts.AGDisplays offers a drop in replacement service for customers who need to replace an LCD or LCD component when their original panel/part is unavailable;this service is also for customers who are looking for a cost effective, suitable replacement or upgrade to their existing LCD. AGDisplays offers availability of standard or custom high-quality LCDs of virtually all shapes and sizes.

Replacing or upgrading the LCD component of your equipment sounds intimidating. It is rather simple if you begin your search with AGDisplays.

Using a replacement LCD does not compromise on quality and compatibility;we ensure functionality and performance are top priority because we know how critical the LCD interface is for your application.

You may receive notifications from your original equipment manufacturer about your LCD panel. There are a couple of announcements to pay attention to. The most important two are the end of life (EOL) announcement and the end of sale date. The end of life announcement will officialize a future cease production date for the indicated part number. It may also indicate the end of sale date, which is the last date customers are able to order the product through the manufacturer. After this date, the product will no longer be for sale. Typically end of life announcements come six to twelve months before the last time buy date. A few months later is when your last time buy will ship.

If you decide by this point that your equipment is well suited to use the LCD replacement, you may want to grab these panels when they get into the last time buy phase. If you find yourself ready to upgrade after EOL and last time buys have passed, don’t fret.A drop in replacement unit extends the lifecycle of your unit in the case of EOL or unavailability of original parts.

There are many signs an LCD will give the user to indicate that it may be due for replacement or upgrade. Even users who are not LCD experts will be able to tell when it is time to replace.

Outwardly, your LCD will show physical signs of damage such as a cracked or scratched, foggy or contaminated screen.Mostly, these damages are quickly noticeable to the naked eye and the first obvious sign that your panel may need a replacement. These are clear indications that the outside of your LCD has been damaged and is in need of evaluation or replacement. The application environment will determine the urgency in which you’ll want to replace the LCD. Cracks in the LCD may leave the LCD vulnerable to contamination and dust, which in turn can extend damage and/or decrease visual readability of the display.

Most LED technology estimate LED lifetimes to be upwards of 100,000 hours of useful life. This works out to be about six hours of usage a day—and 45 years of service, whew! So one can assume that LCD components will fail before the LED backlighting system will degrade. However, degradation does happen with long term usage. If your LCD is looking less bright than it should be, it is possible that a component in the display’s backlighting system needs replaced or upgraded.

LCDs that are broken internally may only show a black screen, a white screen, or even show no data when turned on. Other indications will be white/grey/black discoloration spots (called mura) of the display itself when it is turned on, regardless of the data/color that is shown on screen.

Another indication of a dying LCD aredamaged pixels. If you notice a small speck of white or black on your screen that does not go away, even as the screen changes, you may have a damaged pixel or two. There are a few different types of pixel defects, hot, stuck and dead pixels. Hot pixels present themselves as always ‘on,’ they always appear white in color. Dead pixels are always ‘off,’ and look black at all times. Now a stuck pixel is either stuck ‘on’ or ‘off’ so they may appear the same as a hot or dead pixel. These (sometimes) are solved by switching from bright to dark colored screens quickly to unstick these. However, this isn’t a reliable treatment for stuck pixels.

If you’ve notice defective pixels on your LCD screen, do not panic! Some manufacturers have a standard in which it allows a certain amount of pixels in production. Overall, if the LCD in question has an increased rebellion of pixels, whether hot, dead or stuck, the LCD may be of low quality or the pixels are going bad.

Sometimes white, black or multi colored streaks appear running horizontally or vertically along the display. If this is happening on every screen, this is a likely sign that something is wrong inside the LCD.

Signs of LCD degradation include those missing pixels, the dimming of screen brightness over time, and even the loss of color and contrast in a display. If you need more assurance the LCD is the problem, consult AGDisplays to discuss our replacement options.

Once you have found the correct part number, see HP Consumer Notebook PCs - Ordering HP certified replacement parts. Use the instructions in this document to order a replacement part.

HP recommends that you only order parts from an authorized HP repair parts dealer. Parts ordered from third-party companies might not perform as expected and might cause additional

As often as you use your smartphone, it’s almost inevitable that you’ll eventually drop it. You may be extremely careful, but it only takes one fumble for your phone to tumble. While iPhone screens are designed to withstand impact, you might still end up with a shattered screen.

The good news: a broken screen doesn’t mean your phone is kaput. In fact, if only the glass is broken, the fix is quick and inexpensive. The bad news: if the LCD screen is broken, you’re looking at a pricier repair.

If you’ve looked into replacement parts, you’ve likely come across two very different options: a glass screen, and an LCD screen. While the first option is cheap, the second is definitely not. Here’s the difference:

1. The glass screen is the exterior layer on your phone’s display. While it is specially engineered for durability, it’s still just glass (between layers of plastic film), which is why it’s not very pricey to replace.

Most of the time, the damage to your screen will be pretty obvious. You’ll see the spider web patterns of shattered glass across the front of your iPhone. Occasionally, however, the glass screen will be intact, and you might not realize the damage until you try to use it. Whether the damage is visible or not, it’s a good idea to run a quick diagnostic to determine the extent of it.

If you encounter any of these problems, you’re dealing with a broken LCD screen. If the glass is shattered, but the display is clear and touch capability is working, that’s a good sign. The problem is probably just the glass screen.

Whether you’re dealing with cracked glass or a broken LCD screen, you can find a quick, reliable repair service at FastPhoneRepair.com. Our qualified technicians will get your iPhone repaired and up and running again in record time and at reasonable rates.

The difference between a LED TV and a LCD TV is that they are both LCD TV’s except one has LED stripes and the other has CCFL Backlights- (Florescent Tubes). I used a Philips Magnavox Emerson LG TV when testing these repaird, but they should work on other TV brands that are similar. Before you do any Repair, check to see if you are still under warranty, or are covered by a recall of your TV!!

Unplug the cable between power board and the main board. If the back-light turns on it means that power board is working and the problem is with the main board

If your Plasma or LCD/LED or CCFL/LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it *may* need some new capacitors in the power supply board or a replacement board

Unplug the cable between power board and the main board. If the back-light turns on it means that power board is working and the problem is with the main board

-Upon three unsuccessful start up attempts the TV locks itself in protection mode and needs to be disconnected from AC for 30-40 seconds before power attempts can be restore-Display Locks after 10 minutes–

1) the front green LED of your TV comes and stays on for 20-30 seconds, then turns off for 1-2 seconds and then keeps cycling like that, but the display never comes;

2) the display comes on for a brief few seconds, then the TV shuts off; in some models the display may not even come on, but still the relay clicking on and off and the green power LED activation and shutdown can be easily observed.

Look at the screen. If you see a blank screen with a red key on the bottom of the screen, press FUNCTION and MUTE at the same time. This will unlock the channel

A model number is needed to determine the unlock procedure, but most likely you will need a remote to unlock most TV’s. Below is a common lock procedure.

Choose On to disable all the buttons on the front of the TV. FPA Lock On will appear on the TV screen each time you press buttons on the front of the TV. You can still operate the TV with the remote control. You can still use the POWER button on the front of the TV, but only to turn off the TV (not on). Set FPA Lock to Off to cancel this feature so you can use the buttons on the front of the TV again.

3. Press and hold each of the remaining buttons on the TV, one at a time, for about five seconds, and then release. DO NOT use the buttons on the remote control - only use the buttons on the TV itself.

6. The TV should start automatically scanning for active channels from your input signal source. Make sure you have a good signal (antenna or cable or satellite).

If the TV still does not display anything, try the menu button on the TV and see if you can access the menu. If not, try using the remote control’s menu button.

If the TV is still locked and will not respond to any commands from the front panel control buttons or the remote control unit, it is apparently locked in a failure or diagnostic mode, and would probably have to be diagnosed and repaired by a reputable TV repair facility. Good luck.

If it is a thin vertical line that appears on certain video resolution/image then it is normal and is indicated in the users manual under troubleshooting. If the line is almost half the screen, it could be a problem with the cable connection between the LCD panel and logic board, or the LCD panel itself. Try reseating the cable first if it’ll solve the problem. I’ve done similar issue in the past. Reseating the cable worked for a couple of months till eventually the LCD panel is the problem. Replacing the LCD panel is quite costly and impractical.

If the lines are there all the time or intermittent but in the same location it is an indication of a bad panel. The panel driver can also be the cause of this symptom.

If the lines/bars are across the OSD Menu, and all the video signal inputs also same result, that means the TV LCD Panel is defective Most of the time this symptom is caused by a bad LCD Panel 95%. You can try refitting LVDS Cable or replacing Main Board capacitors or replacing Main Board—5%

Bad news unfortunately, their are two possible causes for what you have described, one would be a fault with the picture drive pcb ( Power Control Board ), and the other is physical damage to the LCD cell matrix, (screen).

There’s videos on how to fix this. It has to do with putting foam, in between panel frame and screen, which applies pressure to solder joints, which then completes the circuit- Contact my10cents, for better explanation.

Big Black Bar on bottom of TV Screen– If the bar that appears in the bottom is showing the energy saving logo, HDMI, Dolby surround and pc mode capabilities look into your remote.

Is the OSD menu affected as well? If yes then possibility could be the LCD Panel or the t-con board. Since you have replaced the t-con board then possibility is the LCD panel. There could be also a possibility of mainboard where upgrading the firmware could restore the picture. If the OSD menu is not affected then the LCD panel is good.

If the lines are across the OSD menu then chances is very high the LCD panel is the cause of the problem otherwise it can be due to bad T-con board or even Mainboard. Have you tested on the OSD menu to see if the lines are really across the menu?

White Lines– There are several possibilities that can cause white lines on an lcd screen. One would be high temperature on the logic board. Logic board drives the LCD panel and when it overheats can cause this display problem. One solution would be to clean the vent holes around the TV. One possibility that I have experienced myself servicing is a bloated capacitor on the power supply board. The worst possibility is a defective LCD panel, which is costly to repair, and sometime more practical to buy a new TV set.

Do you get blue screen when using x-box or DVD, VCR? Have you tried to reset cable box if you have one? Reset TV. Check all cable connections? Try these first.

Do you use the Set top box for cable channels? If yes then try connecting through HDMI and see if you can see the TV. Also do you get blue screen when using x-box or DVD, VCR?

What made you decide to change the mainboard? I ask because if the MENU does not appear, then this indicates a problem elsewhere within the TV. Also, did you check for any swollen, or bulged capacitors on the power supply board?

There are several problems that could cause this problem. It could be the connection from the T-Con board to the panel, try wiggling these cables around and see if the picture comes up even for a second. The Mainboard or it’s cables are not the issue in my opinion. The isdsue is either going to be a bad capacitor, faulty output from the power supply to the T-Con board, a bad connection from T-Con to panel, or the T Con or the panel itself are faulty.

Basic things you can do is to check the connections. If you have a cable box, check the video connections. And while doing that, unplug the TV and the cable box from the AC outlet for it to reset. These are the most likely cause of a blue screen

Most of the new TVs display a blue screen when theres no signal for it to lock on. Try unplugging it for about 5-10 minutes and see if that clears up the problem. Why? Because they have microprocessors in em (computer chips) and just as like with any other operating system, they can hang up or crash. This isnt an uncommon problem with todays TV sets. Unplugging it for awhile resets the microprocessor (in other words, it causes it to re-boot when you plug it in again).-

It could be the connection from the T-Con board to the panel, try wiggling these cables around and see if the picture comes up even for a second. The Mainboard or it’s cables are not the issue in my opinion. This is due to either a bad capacitor, faulty output from the power supply to the T-Con board, a bad connection from T-Con to panel, or the T Con or the panel itself are fault. Also, it’s possible the A/V receiver’s Video On feature was turned off by an electrical surge or something else.Turn the Video feature back to On and suddenly that bad blue screen was gone.

Repair/Solution: Change the cable box to a fixed resolution. OR have the customer install the latest TV firmware which can be located at your TV Brand Customer Support

Your power board needs serious help–If you want to repair you have to replace Switching Mosfets, disc capacitors and of course the main fuse, Rectifier Diodes and most of the time the transformer–Costly–Easier to replace Power Board–There is a chance the strike come through the cable line, so it’s possible the Main Board needs repair–That’s a small chance though, but I thought I’d let you know–Replacing power board should repair your TV. During a lightning storm, electrical power surges is induced to the transmission line eventually end to our household appliances. Our TV sets, computers are the most susceptible. For the TV set, the basic cure is to leave the TV unplug from the AC outlet for it to discharge and reset

5. wait another 30 seconds and some type of picture should appear—If that does not work–Unplug TV for 10 minutes and then hold power button on TV for 60 seconds–Plug in and turn on.

Unplug TV– On TV, hold the power button down while pushing and holding each button for a few seconds. After going through all buttons, (on TV) then plug TV back in and it should power up–

When the TV, has no Picture or Sound. Led turns from red to (Blue or Green). It means the Main Board has sent out the start up signal to the PSU (Power Supply) Board.

Now we need to know if PSU Board has all the correct output voltages. This means checking the secondary side output voltages of Power Board. Probable causes are the Power Supply, the T-Con board, Main Board or the LCD panel itself has failed.

No Picture/Sound The person who looked at my TV, stated that the high voltage power supply needs to be replaced. He explained that I have a low voltage supply which is why the power button is lit once pressed, and a high voltage supply which needs to be replaced.

Solutions: If the unit tries to turn on but begins to cycle on and off before any video is displayed and all of the SMPS (Power Board ) voltages are good, disconnect the LVDS cable at the T-Con board

You will have to go into the TV and check for capacitors or burn marks or cracked solder around the pins–Main board could be IC’s, or regulators–Panel–Disconnect panel and see if your TV stay’s on—

The flashing green light indicates a fault on the power board inside your TV. This will be due to a faulty component like a capacitor or voltage regulator. Faulty electrolytic capacitors on the power board are the most common cause of this problem. These capacitors will often leak and stop working as the TV set gets older,but could also be caused by the Main Board or the inverter board. (LCD TV ONLY) So we will have to take a look inside and maybe do some circuit testing and a visual of your boards-

In a dark room take a flashlight and at an angle shine it on the screen and see if you can see any movement. If you can see movement or see your menu then its backlight failure. If totally black screen with sound then its T-Con board. So if you see movement on a led screen, then it’s your LEDs inside the panel. If on a LCD TV you see movement and lamps are not turning on, replace inverter. If with a LCD TV your lamps turn on, with no picture replace T-Con Board.

Plasma is the most durable in terms of panel failure. LED/LCD is terrible for panel failure. (But every model gets bad apples. Samsung LED/LCD panels die frequently. LG panels are a lot more reliable.) Overall I’d say plasma is more reliable, and even if it fails, in most cases plasma is repairable, LED/LCD is expensive to repair and often difficult to troubleshoot.

3)- Switches off for a second or two intermittently. Relay clicks and standby LED remains green. Switches off intermittently with green LED on, no sound or no picture.

A blurry image on a high-definition LCD TV is typically the result of a mismatch between the TVs resolution capabilities and the resolution of the signal that is coming from connected devices, such as a DVD player or satellite TV receiver. Typically, blurry pictures result when a peripheral device connects to the TV through non HD cables and jacks.

Is your electricity bill escalating at an usual rate? Check with your utility provider and confirm that they haven’t raised their prices. Otherwise, an old TV or another major appliance could be to blame.

Here’s how to test the theory if you suspect the TV is raising your energy usage. Unplug the TV power cord for a few weeks this month and watch how it impacts next month’s bill. Use your other electronics, like your sound system or computer, as usual, to avoid influencing the result! This method can be used to test out the electricity cost of almost any appliance in your home.

These days, streaming services are central to entertainment. Do you find yourself relying on your laptop or tablet for binge-watching? Does your current screen make your new game console’s graphics look like a bundle of pixels? If so, you’re missing out on the wonders of 4K UHD smart TVs!

Smart TV WiFi capabilities allow you to stream your favorite shows and movies without relying on a laptop or another device. They’re also more compatible with necessary software updates to deliver your favorite content. If your current TV screen isn’t letting you enjoy your entertainment options to their full potential, it’s a good time for a change. After all, why pay for top-of-the-line gaming systems if you can’t take advantage of them?

Does your favorite soap opera look more like your teenager’s tie-dyed leggings? If red, blue, or greenish stripes interrupt your viewing experience, there’s probably something wrong with your TV’s hardware.

Lines across a TV screen are usually caused by loose or frayed cables within the screen, which is why knocking on the side or back of the TV can be a temporary fix. (You’re knocking the cables back into place). Repairing this problem leaves you with two potentially expensive options: a) calling a professional repair person, or b) ordering the parts and opening the TV panel at the risk of damaging it permanently and voiding the warranty.

The TV is on, but the picture doesn’t look right. One side of the screen is faded. You try to look past the blemish and focus on the movie in front of you, but it only takes a few minutes to identify the real villain in this story: the faded quarter of your TV screen!

How do you know if your TV is going out? There’s no clearer answer than faded spots on your TV screen. Sadly, this issue is not uncommon. What’s more, fading may be accompanied or followed by more significant problems, such as your screen fading to black just minutes (or seconds) after turning on the TV.

Fading TV screens point to a compromised backlight system. Some models enable you to “Picture Test” your TV to troubleshoot this issue. A “Picture Test” walks you through an on-screen questionnaire to help you determine if the issue is the source (the input, channel, or signal) or the TV hardware.

If your TV’s backlight display is faulty and you don’t have a repair and replace benefit or manufacturer’s warranty, you may have to shell out some cash on professional repairs. Or, you can upgrade anytime with bite-sized payments on rent-to-own TVs from Rent-A-Center.

First, you check your remote’s batteries. Then, you walk up to the TV stand and give the TV’s power-on button a long, hard, angry press! The power light blinks and finally, nothing happens!

It seems like your TV takes longer to come to life with every day that passes. On top of that, the screen makes clicking noises as if it’s straining to turn on. Most of the time, an unresponsive TV screen is caused by a faulty capacitor or power system—which is difficult to troubleshoot and expensive to repair.

If your TV takes forever to start, it may be announcing its impending death, which means you’re better off investing in a replacement than wasting money on a short-term fix.

Poor TV sound quality is a common complaint among TV owners. For some, the issue presents itself as distorted dialogue that’s hard to understand and is accompanied by staticky background noise. For others, poor sound quality means no sound is coming from the TV at all, or that its volume capacity has dropped significantly.

Before you ditch your TV, check your audio settings and cable connections. Try plugging in a different set of speakers to test out the sound, too. If all of those check out, it’s time to either replace the TV or supplement it with an epic sound system.

Burn-in, also known as ghost image, is a faint outline that evidences permanent damage to your TV. This damage usually occurs when the same image is displayed for extended periods. For example, if you always tune into the same news channel—the shape of their logo could become burnt into a corner of your screen.

Burn-in is not fixable, and many manufacturers exclude it from their warranties. To prevent it, you should flip through the channels regularly, avoid leaving your TV on for too long, and enable auto shut-off in your settings.

No DIY or professional fix can purge a ghost image once it sets in. If there’s a haunting shadow on your screen, the best choice is to cast it out of your home and replace that TV with a new, ghost-free one from Rent-A-Center.

Does your television turn off unexpectedly whenever you’re using it? A TV turning off unprompted can ruin progress on your favorite games and kill the vibe during watch parties and events. However, a few factors may be to blame for this issue. Not all of them are expensive to repair, but it’s worth troubleshooting to get to the root of the problem.

It was an accident. The game got really exciting, and the remote just happened to hit the TV. Things just got out of hand, and somehow, your TV screen cracked. Maybe the TV stand was even a casualty. Whoops!

A crack on your TV is a problem for obvious reasons: it interrupts your viewing experience and represents damage to the hardware. However, there are less evident yet more concerning reasons to replace a cracked TV:

Most of the time, a cracked TV screen can’t be fixed. Moreover, the health risks of keeping a broken TV around far outweigh the benefits of being able to watch movies through a shattered screen.

If you’re asking yourself, “Should I buy a new TV?” The answer is likely, yes. Whether your current TV lacks the features you need, or you’re experiencing TV issues like water damage that are too expensive to repair—it’s time to kiss your old TV goodbye!

Accidental Damage is any damage due to an unintentional act that is not the direct result of a manufacturing defect or failure. Accidental damage is not covered under the standard warranty of the product. Such damage is often the result of a drop or an impact on the LCD screen or any other part of the product which may render the device non-functional. Such types of damage are only covered under an Accidental Damage service offering which is an optional add-on to the basic warranty of the product. Accidental Damage must not be confused with an occasional dead or stuck pixel on the LCD panel. For more information about dead or stuck pixels, see the Dell Display Pixel Guidelines.

No, accidental damage is covered for Dell computers or monitors which are covered under the Accidental Damage Service offering for that specific product.

The LCD glass on the display is manufactured to rigorous specifications and standards and will not typically crack or break on its own under normal use. In general, cracked, or broken glass is considered accidental damage and is not covered under the standard warranty.

Internal cracks typically occur due to excessive force on the screen. This can be the result of some object hitting the screen, a drop, attempting to close the lid while an object is on the keypad area, or even holding the laptop by its screen.

Spots typically occur due to an external force hitting the screen causing damage to the LCD panel"s backlight assembly. While the top layer did not crack or break, the underlying area was compressed and damaged causing this effect.

If your Dell laptop LCD panel has any accidental damage but the laptop is not covered by the Accidental Damage service offering, contact Dell Technical Support for repair options.

Dell monitors cannot be repaired by an on-site field engineer or at the mail-in repair center. If you notice any damage to the monitor, you must purchase a new monitor.

Ever had your TV showing nothing but a black screen even if the audio was working? Unfortunately, that’s a common issue with low/middle-end LCD/LED TVs these days… Even more frustrating, this issue often comes from a rather tiny and cheap component that can be easily replaced. Most common issues are:

One of my relatives had this exact symptom happening all of a sudden. This problem on low-end TVs often occurs within the first couple years. As the repair costs for that kind of TV is pretty low, considering repairing it yourself might be a good idea!

The first step into repair is to find the root cause of the issue. As backlight failure is a very common issue, this is the first thing to test. To do so, the easiest way is to power on your screen, put a flashlight very close to it and check if you can see the image through. The image would be very dark, like turning the brightness of the screen very very low.

That implies disassembling the TV to access the backlight which is between the LCD screen in the front and the boards in the rear. In my case, with a Samsung F5000, I had to process as follows:

First we have to remove the back housing to reveal the boards (from left to right: main board, T-CON, power supply) and disconnect the LCD panel from the T-CON board.

Note: Older TVs have neon tubes for backlight, which is thicker and less exposed to this kind of failure. LED backlight is the most common thing these days, but do not mistake an LED TV with an OLED TV. The first one is a classic LCD panel with a LED backlight, whereas the second is an OLED panel that doesn’t need any backlight as it is integrated in each pixels (making the spare parts much more expensive by the way).

As we can see, the backlight system is made of 5 LED strips. First thing to do is look for burnt LEDs. Most LED backlight systems have strips set in series, meaning that if one of the them fails, all the system goes dark…

Using a multimeter, we can confirm that the strips are indeed set in series, so now we have to test each strip individually. Professionals use LED testers such as this one (about 40$ on amazon) but as I didn’t had one at the time, I decided to make one, McGyver style!
