when troubleshooting an lcd panel monitor that is malfunctioning quotation

I need to reset my monitor’s settings back to default factory settingsTo reset your monitor’s settings back to its default factory settings, follow these instructions:

My monitor is not turning on even though it is plugged in (external power supply)First, try another device in the same outlet to determine if the outlet is working properly.

Is everything firmly plugged in? It is easy for cables to become loose and not firmly connected, especially if you are using a mobile system. Please check to ensure everything is securely plugged in.

The LED light on the power supply should be GREEN. If the LED light is not on, then either the power supply is dead or there is no power being generated from the power source. Try another power source (outlet) and if this doesn’t work, there may be an issue with the power adapter.

Amber Light: The amber light indicates the monitor is receiving power but is not receiving the video signal being fed from the signal source (camera, computer, etc). This may also signify that the monitor is currently set to the wrong video input; you may need to press the “Auto/Switch” button to select the appropriate input (VGA, HDMI, etc).

Green Light: If the power is on, the connections are secure, the video signal source is on, and the light is still GREEN, then this dictates a problem internally with the monitor; it needs to be returned for repair.

Green Light: If the power is on, the connections are secure, the video signal source is on, and the light is still GREEN, then this dictates a problem internally with the monitor; it needs to be returned for repair.

My monitor screen is completely black, even though it is powered onIs everything firmly plugged in? A loss of video signal will cause the monitor to go black and then turn off entirely. It is easy for cables to become loose and not firmly connected, especially if you are using a mobile system. Please check to make sure everything is securely plugged in.

Your monitor possibly has TRU-Vu’s Dim-To-Black feature which allows you to control the screen’s brightness and contrast by pressing the arrow keys in the menu. The reason it has gone completely black could be because the dim-to-black was turned all the way down. Press the arrow up to the right to raise the brightness again. If this does nothing, try pressing the left arrow keys.

Why does my monitor keep entering sleep mode when I turn it on?The primary cause is usually that the monitor is not receiving a video signal from the signal source (camera, computer, etc). The monitor will automatically enter sleep mode if it cannot detect a video signal.

Example: If you have the computer plugged into a monitor and the computer is off, when you power the monitor on, it will turn on for a few seconds, then automatically switch into sleep mode and turn off. Once you turn the computer on, the monitor will automatically recognize the signal source and power on.

The monitor will automatically switch into sleep mode if your video signal source (camera, computer, etc) is off or disconnected. Make sure your source is on and firmly connected.

If the LED on the monitor is amber, this means the monitor is receiving power but not receiving a video signal from your source. Ensure the monitor is set to the correct input and try swapping out sources to determine if that is the root of the problem.

If possible, try using a different monitor with the same cables and source. If the new monitor works, then there is an issue with the original monitor. Contact us for a repair RMA.

Why are there black bars and/or squeezing (banding) with my monitor?If there are black bars around your signal and/or a “squeezing” effect, this means that the aspect ratio of your monitor and the incoming video signal do not match.

Make sure the monitor’s picture size setting is set to the factory default, not zoom, fit or stretch. For optimal picture quality without distortion, black bars or squeezing, it is always best to match the aspect ratio of your video signal with the aspect ratio of the monitor.

How do I know if my monitor is really showing true 4K video?Make sure that that the signal you are sending is 4K resolution (3840x2160). You can test this by pressing the monitor’s Menu button. The monitor’s Menu screen will display the incoming video resolution and timing in the top-right corner of the screen.

My touch screen is not working.All touch panels must be connected to a computer via USB or RS232 cable. This allows the touch panel to communicate with the computer.

If you recently downloaded a new touch panel driver, you must also delete the old driver and reboot your computer. Make sure you have deleted any old touch panel drivers and then restart your computer.

My touch screen is not registering correctlyAll non-HID compliant touch panels will need to be calibrated during the initial start-up and may need recalibrating at some other point in the future. This is accomplished via the touch panel software installed on your computer. For a detailed walk through, please contact us.

Certain touch panels are susceptible to issues due to grease/dust/water and therefore may need added care. If this is a constant problem, please contact us for further assistance.

The buttons on my monitor are lockedKeylock is a safety feature offered by TRU-Vu to prevent unauthorized personnel from changing the desired monitor settings. We do not publish the lock codes for public knowledge; please contact us for the unlock codes.

I increased the Brightness setting on my Sunlight Readable monitor, and now the image is washed outIf you would like to achieve a brighter image than the default settings on a TRU-Vu SRM-Series Sunlight Readable monitor, we recommend keeping the Brightness setting at the default setting (you may need to perform a factory reset/recall if you’ve already adjusted the Brightness), and then increase the contrast.

The speakers are not very loud on my monitorTRU-Vu speakers are provided for signals and alerts; these are not intended for voice or music. If quality of sound is a major concern, we advise using external speakers.

My monitor is displaying a message saying “Sync Out of Range”If you are seeing this on your monitor, it means you are sending a video resolution to your monitor that is higher than your monitor’s native resolution.

Please review the TRU-Vu data sheet to determine your monitor’s video resolution and set your incoming video source to the same resolution as listed on the monitor data sheet.

Prepare the screen by turning it off and wait until it is cool to the touch. Cleaning warm or hot screens makes it more difficult to clean and can even damage the screen.

It is always recommended to spray the microfiber cloth first, then clean the screen with the moistened cloth. Do NOT spray the monitor screen directly.

For heavier duty cleaning, create a solution of 80% alcohol mixed with 20% water and use the damp, not wet, cloth to clean the screen and panel surface.

I need to clean my monitor screen (with protective glass)We highly recommend WHOOSH Screen Cleaner. It is 100% natural, non-toxic, and environmentally friendly. You can also use any standard glass cleaner.

This article is for those of you who have a desktop computer that you have turned on, the lights are on the case and you can hear the fan running…but your monitor won’t turn on.

There are many reasons why a monitor won’t turn on even if the PC seems to be functioning fine. Some require simple solutions others might mean a trip to your local computer repair business.

First of all, there might be nothing wrong with your computer at all. The first and easiest test is to see if it is your monitor that is at fault or your monitor connections rather than your computer.

Okay, this is very obvious but sometimes cables can come loose. Check that the plug of the power supply is firmly in the wall socket and that the other connection if firmly seated in the monitor and that the wall socket is switched on! If after having done this and your monitor lights up, you may feel rather foolish but at least you can get back to work – or play.

If your monitor is still black, try plugging the monitor into a second electrical outlet. Still no luck, then you need to progress to the next troubleshooting step.

When your computer is on and your monitor is showing just a black screen, use a torch and shine it directly on the screen. If you can see an image using the touch then it is most likely the monitor’s backlight that is at fault and you will need to replace it. This is not a job for anyone without computer repair experience and due to the risks of potentially breaking your screen, it is recommended that you seek help from a reputable repairer for this problem.

If none of the above-listed troubleshooting options has solved your problem it’s now time to test if you can rule out the problem being with your computer and knowing that it is a problem with your monitor or connections to your monitor.

If you have another monitor handy (say from another computer in your home or even friends), use this to test if your monitor is faulty. Simply disconnect your existing monitor and connect the second monitor which you know is a working monitor. I would do this using the second monitor’s power supply and cable.

The next thing to test is whether the problem may be the supply of power to the monitor, including the cable.  Some monitors are designed with a built-in or internal power supply, whilst others use an external type (similar to the kind used by a typical laptop).

If the power supply is interchangeable with the second monitor I would now connect the second monitor using the original monitor’s power supply. If the monitor still lights up then you know the problem is not the power supply.

If the screen does not light up, then you may have a very simple solution, although not a really low-cost solution. Your solution may be just to purchase a new power supply which you should be able to obtain from stores such as Computer Alliance or MSY Technology. However, before you go and buy a new screen power supply, firstly reconnect your original monitor with the second monitor’s power supply and see if your monitor lights up. If it does then you know that all you need is the new power supply.

This is as simply a test as for the power supply. Just make sure that the connections of each end of the cable to your computer and monitor are sturdy and secure. If after tightening these up your monitor works, again you might feel a little foolish but have a great outcome.

If this does not work, switch cables to see if there is a fault with the cable. If your computer and monitor each supports a range of different connection types, try VGA (15 pin blue), DVI or DL-DVI-D (white), HDMI or Display Port. If this solves your problem then you have the simple solution of purchasing a new cable which can be done online or at a computer store such as Computer Alliance, MSY, Umart or even Officeworks.

If the monitor remains black then you could have a faulty monitor that you are probably better off replacing than trying to repair. If you have still not ruled out that it could be a problem with your computer rather than the monitor, then you need to proceed to the next steps of troubleshooting why your monitor won’t turn on.

Checking the graphics card requires opening up your PC if you have no experience with repairing a computer this is definitely a job for a computer repair business.

If you do have the experience, then remove the graphics card and reset it in the PCI-e slot (or another PCI-e slot if your motherboard has more than one) and try another one that you know works. If this does not solve the problem then it may be that it is a problem with your computer’s motherboard.

Like a graphics card, you could (if you are an experienced computer repairer) switch motherboards to identify whether or not this is the cause of your monitor’s screen being black.  This involves quite a lot of effort and not recommended for the inexperienced or faint-hearted. You may be better off tackling something a little easier. Replacing, swapping or just reseating the RAM modules in your computer.  Your typical motherboard comes equipped with two or four RAM slots, usually with 1, 2, or 4 modules (sticks) of DDR2 (older), DDR3 (newer) or DDR4 (newest). By removing and then reinstalling these, you might be able to solve your problem.

If after all of this troubleshooting you still do not have a solution to your problem we suggest that you give us a call at Affordable Computer Repairs and Solutions (3397 1215 or 0409 974 707) and we will endeavour to assist you and provide a solution as to why your monitor won’t turn on.

Please note, don’t forget that your monitor may still be under warranty. You should check this prior to doing anything else as it could save you some money. However, sometimes the length of time that is taken for repairs under warranty means that if you want to keep working asap and don’t have another monitor handy, you might want to fix it yourself or get it repaired by a local computer repairer.

Also, please note that if your monitor is still under warranty and you try to repair it yourself and are unsuccessful, then more than likely you will have voided your warranty and will then have to pay a computer repair technician to fix it for you.

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.

For more information about Dell Limited Hardware Warranty and Dell"s Accidental Damage service offering, see the Dell Warranty & Support Services page.

NOTE: Other damages may be considered customer induced if determined by Dell Technical Support, an on-site field engineer, or at the mail-in repair center.

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.

Laptop users can strive to make the most of their laptops to maximize stability, longevity, and usability. Understanding and implementing a few best practices for the safe handling of their laptop will enable them to enjoy their laptop for many years to come. For more information, see the Dell knowledge base article Dell Laptop Best Practices for Care, Use, and Handling.

Roll back your video driver to the previous version if the pink screen occurred immediately after a driver update (you’ll need to be logged in as an administrator in order to manage drivers). Click "Start," type “device manager” (without quotes) in the box and select “Device Manager” when it appears in the search results. Double-click “Display Adapters” and double-click your video adapter. Click “Roll back driver” and click “Yes.” Reboot the system to see if the issue persists.

Return your monitor’s display settings to the factory default if the pink screen tinting appeared after any changes were made in the settings. Most monitors have a Menu button near the Power button, and you can scroll among the various options using the monitor’s directional keys, which might be arrow keys, or “+” and “-“ keys. In most cases, the factory reset option is located in the main menu.

Turn off the monitor and unplug the video cable from both your computer and the monitor. Make sure that the cable itself is not damaged or kinked, and that none of its connector pins is bent or broken. If the cable is damaged, replacing it should solve the problem. Even if the cable does not appear damaged, it might still be faulty, so try swapping it with another and see if the display returns to normal.

Swap the monitor out with another in the office that you know is working correctly. If the screen is still pink, the problem most likely is either a bad video adapter or a bad driver.

Reboot the computer, then tap "F8" to pull up the Windows Advanced Startup Options menu. Select “Safe Mode” from the list and press “Enter.” Log in as you normally would. If the screen is no longer pink, a faulty video driver is probably to blame. Continue following the steps below. If the screen is still pink, you might be looking at a faulty video adapter. Depending on your computer’s hardware configuration, repairing a faulty video adapter may involve replacing an add-on card or replacing the motherboard entirely. Unless you have some experience with computer repair, either of these tasks should be performed by your IT department or a technician at a computer repair shop.

Download the most current driver for your adapter by visiting your computer manufacturer’s website. You might need to visit dedicated “drivers and downloads” section, or pull up the product page for your computer model. If the video card in your machine did not come with your computer when it shipped from the factory, visit the video card manufacturer’s website for the driver. You can obtain your video card make and model by opening Device Manager (see Step 1).

So, why there are green lines on a monitor? Well, several factors might be at play if the displays attached to your PC aren’t operating correctly. It’s conceivable that your adapter or cable connection is the problem. Change the cable if it doesn’t work. If nudging doesn’t work, try another.

Throughout this post, we’ll explain why green lines occur on your display and the best techniques to remedy them. The extra information will be invaluable in fixing all of your monitor’s green lining concerns. It’s time to delve in!

There are a variety of possible causes for horizontal green lines or vertical lines on your computer screen, from outdated video card drivers to damaged ribbon cables and improper video cable connections. To determine whether the problem is software or hardware, you may examine the BIOS settings.

When you see a green line on your computer screen, you should inspect your display for any faults, including all the connectors. There might be a problem with the cable causing the monitor’s color to lose signal.

It would help if you examined the possibility that your computer has been infected with a virus or other malicious software. While this isn’t one of the most prevalent reasons for a green vertical line on the display, it’s still possible.

Faulty graphics drivers might also cause problems with your monitor’s connection to the computer. However, although this is the most common symptom, it may also be seen in the form of green lines on a monitor.

Because Windows 10 does not contain the BIOS, any horizontal or vertical striations on your display problem result from a software problem. If you don’t see any horizontal or vertical lines on your Windows 10 computer screen, this is likely a hardware problem.

It’s possible that your computer’s drivers don’t cause the flickering green lines on your display if they occur immediately after the computer has started up and not on the initial screen while the machine is starting up.

The status of “This device is operating well” indicates that the hardware failure has no problems connecting to Windows 10 once the procedures are completed.

You’ll get an error number and an explanation of the issue if the component isn’t operating correctly. The device has been deactivated and must be re-enabled to fix “error code 22,” for example.

You may also try downloading the drivers from the hardware manufacturer’s website if it doesn’t work. Make sure you’re looking at “Display adapters” (in this case, “NVIDIA GeForce 9800 GTX/9800 GTX+”) and the graphics card’s name.

This is the standard procedure to remove the green lines on the monitor, regardless of whether your motherboard is set to UEFI or a classic BIOS configuration:

It’s good to have a backup copy of all of your computer’s crucial data before you begin. Even if a BIOS update fails, the data on your hard drive is not at risk.

Making a copy of your BIOS is an excellent idea, too. Don’t miss this step if you have to perform it manually, even if it’s done automatically during an update.

The prior driver version must be installed in this case. Using the drop-down option, choose the previous graphics driver version in Download Center to download and install it.

The second case is a well-known one. It will not install updates if you shut off your computer during Active Hours. For this reason, it is necessary to either modify Active Hours or manually install the application.

Monitoring a computer’s refresh rate can help identify and correct problems with graphics performance. The monitor’s refresh rate refers to how often the screen updates its image. A slow refresh rate can cause visual artifacts, such as green lines, on the screen.

Collectively, these lines indicate that the monitor is not keeping up with the latest graphics rendering instructions. This can lead to an overall degraded experience when using the computer.

The prior driver version must be installed in this case. Using the drop-down option, choose the previous graphics driver version in Download Center to download and install it.

Knowing your screen resolution, even if you aren’t an engineer or a photographer. You can appreciate your multimedia activities better if you know what you have and what you can do. In Windows 10, you may verify your screen’s native resolution by following these steps:

The resolution may be changed by selecting a different option from the drop-down menu. You should only view content that is compatible with your computer’s capabilities.

If you purchase a new external monitor or video card, you may have to change your resolution. If you’re having problems with your monitor, the first thing you should do is check the resolution. It’s a straightforward solution to a variety of visual issues.

When you start Windows regularly, programs and services in the background may cause these conflicts. If you’re having trouble accessing Task Manager, we’ve got the answer.

The monitor cabinet should never be opened to service this item. Everything that hasn’t been stated explicitly in the user handbook should be avoided at all costs.

Do not connect the monitor to anything other than the designated power supply and HDMI cable, which should be clearly stated on the monitor label or backplate.

Ensure that the monitor is close to a working power supply. The monitor’s power cord may be yanked out of the socket with a rugged grip. Attempting to disconnect the display issue by pulling its cord will not work.

Be sure to switch off your display when not in use. A screen saver program and turning off the display when it’s not in use will significantly prolong the monitor’s life.

The cabinet’s design includes ventilation holes. These openings should not be obstructed in any way. You should never shove anything into a cabinet slot or any other aperture!

The green line of death seems to be caused by a hardware problem based on the current symptoms. If you go back in time, you may discover similar problems on non-Apple devices. This problem only appeared on OLED-display phones, to be more exact.

There may be more to the problem with water damage than just a replacement screen, but it’s typically just a matter of getting a new LCD or OLED display.

Language settings are not lost when a monitor is reset to factory settings. Your specific settings, such as contrast, brightness, and picture ratio, will need to be re-entered after a factory reset.

Due to obsolete GPU drivers, the green lines on a Windows 10 laptop are standard. Using specialist driver update tools, you may repair this problem. One of the most prevalent reasons for this issue is a malfunctioning laptop display.

Your phone’s LCD might be damaged if you don’t mend a cracked screen right away. Damage to the LCD screen might occur if dust penetrates the screen cracks. Your phone’s LCD screen might be damaged if you drop it in water or other liquid.

A faulty video connection is most likely to blame for a monitor with no signal. Connect your display and PC using a different VGA cable or ribbon cable to check whether the problem remains. If not, then your video cable is to blame for this problem. Try attaching your display to another computer to see if it helps.

That’s all about the green lines on the monitor from us. An external display with bothersome vertical lines or horizontal lines may be fixed by testing the image to determine what causes these lines on the computer monitor.

It doesn’t matter whether the computer, cable box, or any other input source is to blame; the monitor, its LCD screen, or internal hardware is to blame.

Turn on the laptop and when you think that it should have booted all the way to the Windows desktop (check HDD activity light has settled down), shine a torch at an angle close to the screen and check if you can detect the Windows desktop image. (you may have to peer closely to see it, as it will be faint)

If it does then you either have a faulty video flex cable, faulty video flex cable connection at either end (motherboard or screen) or a faulty LCD screen.

Here is a link to the service manual for your laptop. Scroll to p.61 to view the necessary pre-requisites and then the procedure for replacing the LCD panel.

Since you have to do most of the procedures to check the cable and if it is not loose or has been fractured, (usually around the hinge area where it passes through from the base to the lid) then most probably you will have to replace the screen.

On p.92 are the part numbers for the various screens available for the model. Once you have determined the correct part number (item #2 in list, it is also usually printed on the back of the screen), just Google the number only - nothing else, to get results for suppliers of the screen.

If you think that you can do the replacement yourself, I suggest that when you do and if you are having problems with any part of the repair and are becoming frustrated, STOP. Take a break, think through the problem and calmly start again. This forum is full of people who have said that they ripped out connectors or broke components in frustration, causing more problems than when they started. This is not to put you off doing it, far from it. It"s just a suggestion.

If you feel that doing this is too daunting, then I recommend that you contact 3 reputable, professional laptop repair services and ask for a quote to repair the laptop. I suggest 3, that way if their estimates are close in price then you will have a truer idea of the real cost of the repair, (and also you should know the retail cost of the LCD panel already).

When the screen blacks out, shine a torch at an angle close to the screen to see if you can detect if a display is still there. It will be dim but a darkened room will help.

This can be caused by (depending on laptop model, you didn"t say what model you have) a faulty backlight power inverter, faulty backlight power cable, faulty lid switch, faulty video cable or faulty screen.

If the external monitor display stays on, then you either have a faulty video cable, faulty video cable connections at either end (motherboard or screen) or a faulty screen.

If the external monitor display also turns off then you have a faulty GPU or motherboard (which is basically the same thing as the GPU most probably is mounted directly onto the motherboard.

If you can still "see" the display when the screen goes black it indicates that there is a problem with either the voltage level of the power supply to the backlighting going intermittently faulty or that somehow the connections supplying the power are going more resistive (as best as I can determine the power from the backlighting is supplied from the motherboard and not a separate inverter board in the laptop).

Just wondering if it could perhaps also be a problem with the software control of the backlighting. When the screen dims have you tried pressing Fn + F6 together to see if you can increase the brightness at all?(Fn + F5 dims the screen)

Here is a link to a webpage that shows how to dis-assemble the laptop. It may help if you wish to see if there is anything obvious such as a loose video cable connection etc on the motherboard Unfortunately it doesn"t show how to dis-assemble the lid to view the screen end.

As I cannot find a service manual online, without a schematic diagram it will be difficult to ascertain where exactly the problem is. It may be that you will have to contact a reputable, professional laptop repair service and ask for a quote to repair the laptop

No, all settings and selections you"ve entered such as device codes, favorite channels, and recent On Demand selections are saved and available after resetting your Set-Top Box.

To avoid problems with your Fios TV service, make sure your router is plugged in and turned on at all times. Even if you are not currently using the Internet, your router still needs be turned on so that Fios TV can function properly.

Note: Don"t confuse the power cord that provides electricity to your Set-Top Box with the coaxial cable that is connected to the back of your Set-Top Box. Unplugging the coaxial cablewill notreset your Set-Top Box. Since many issues can occur if your coaxial cable is not securely fastened, now would be a good time to check to ensure all connections are securely connected.

Check to see if this resolves the trouble. If you still have the problem, your Set-Top Box may need to be re-initialized. Contact Us for further assistance.

No, if you routinely have to reset your Set-Top Box more than three times a week, it is likely there is an issue with your Set-Top Box that needs to be resolved. Contact Us for further assistance.

If your remote is not working or you"re having trouble controlling a particular device, use the table below to identify the issue and solve the problem.

If you have multiple TVs, you may be using a remote that is programmed for another TV.Check that you"re using the remote that was set up for the TV you are trying to control.

Something may be blocking the path to the device you want to control, you may not be pointing at the sensor on the device, or you may be too far away.

The device you are trying to control may not be programmed into your remote.To program the device into your remote control, find your remote on the Fios TV remote controls & codes page and select the applicable Set up your remote link.

Your TV settings may have been accidentally changed.Using the remote control that came with your TV, check that your TV is set to either channel 3 or 4 and that it is currently set for the input mode you are trying to control.

If you"ve tried the tips above and reprogramming your remote does not solve the problem, your remote control may be damaged or defective. Click Here to Order replacement remote control.

If your Fios TV Philips remote has been programmed to control your TV and STB, then whenever you press the power button on your Philips remote, both the TV and STB should turn on or off accordingly.

You may find that sometimes when you press the power button on your remote, the STB may turn off but the TV does not. Alternatively, you may find that the TV turns off but the STB stays on.

First, make sure you are pointing the remote directly at your TV and that there is a clear line of sight between the infrared light on your remote and the front of your TV. Press the Power button again.

If the TV did not turn on or off in response to pressing the power button, then the remote is not programmed to control your TV with the correct device code. Consult your remote control user guide or follow the instructions to set up your remote control.

Make sure the TV and the STB are near each other and nothing is blocking the front of either device. Also, if your TV is plugged into the power outlet in the back of the STB, try plugging your TV directly into a wall outlet instead.

If you know that your DVR is authorized but you are seeing a message indicating that it is not authorized when you try to open the DVR menu, this indicates a problem with the connections to your Fios TV setup.

There are two pieces of information that indicate the display resolution. The first is a number that indicates how many horizontal scan lines can be painted onto the TV screen. The higher the number the better picture quality you can expect from your video source.

Theoretically, a 1080p video source will have a smoother picture than 1080i video source but in most normal TV viewing circumstances you may be hard-pressed to see the difference.

There are several reasons why you may not be receiving video reception ranging from an electrical issue to an incorrect channel setting. If you use an HDMI connection, your TV and Set-Top Box may have become unsynchronized.

Make sure the TV"s power is on. Press the TV"s power button. Check to see if the TV is plugged into an outlet controlled by a wall switch. If so, turn on the wall switch.

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!
