how to repair lcd display in stock

If the picture responds to input but displays a messy image, such as jumbled multicolored squares, the AV (audio visual) board may be damaged. This is usually a rectangular circuit board located near the audio and visual cables. Replace obviously damaged parts using a soldering iron, or order a replacement board and carefully install it to the same screws and ribbon cables.

The main control buttons may be faulty. Clean them with a metal cleaner, or jostle to attach a loose connection. If necessary, locate the circuit board they are attached to and re-solder any broken connections.

Check input cables for damage, or try other cables of the same type. If necessary, inspect the circuit board they are attached to and re-solder damaged connections.

In my case the ribbon was half detached. I took the pen solder bold and set it to 180 °C and slowly moved several times with medium pressure along the ribbon and pressed it onto the plate. I had to repeat this procedure 3-4 times until all pixels were working again.1

I investigated my landline phone to repare its LCD according to this good tutorial, unfortunatly I found the cutted connection is not on the main PCB board but on the flat connector itself... and any heat applied (soldering tentative...) to the flat is going do destroid it completly ((

Instead of hot-air gun use hot melt adhesive (https://en.wikipedia.org/wiki/Hot-melt_adhesive) gun. Just use its hot spike, and you will be able to point precisely to the place you need a heat.0

Unfortunately, after two days the display started to lose some segments. What would other people recommend? Is this expected and should I have done something else other than heating and rubbing with an eraser?

Many thanks for sharing the information on how to fix these displays! Worked out perfectly on a asus lcd poster from ages back which gave no screen at all and are not sold anymore to replace.ReplyUpvote

Very good interesting piece. I am no way shape or form of an electronics junkie , but i am more like a jack of all trades and a master of none type. I have a dual power TS-100 hand held calculator where the second digit was pixelated I would say. I googled how to repair it and seen your story. I took my calculator apart and the back side is where that glue strip is at. I could not find my heat gun, thanks to having to move it for the Christmas tree setup. I used my Kitchen Propane stove front burner and waived it over it a few times. It took a few tries but I finally was able to get the dead pixel back. One good thing is the calculator was on so in between heat ups and eraser rubbings I could see my progress and man your fix really worked. Thanks fro the story. My favorite pocket calculator is fixed once again. I wish I would have taken before and after photos, but was too giddy to try your repair idea.0

Google offers no link as to how to open an AEG Voxtel D235 handset. After opening the battery compartment and removing batteries and the two Philips screws at the bottom, the upper half refuses to budge. Is there a method for opening the upper part, to access the LCD screen connector for repair? Any suggestions appreciated.0

This made me squeal when it worked! I fixed an old treadmill computer from a machine I bought second-hand. There was a broken connection on the breadboard so I dunno if that work but we"ll see! I didn"t have a heat gun, blow dryer or clothes iron to use, but I made it work with the end of my hot glue gun. Thanks, God bless!

I just got my CM921 to work - so, carefully unplug or remove the lcd unit from the circuit board (8 pins i think) then separate the white board (same size as the lcd) from the back of the lcd display (it was glued on one side and i used a scalpel) the lcd will then flip over and you can see the ribbon, then follow the instructions above, return the lcd back down on top of the little white board as before and plug it back in...0

There may be a thin conductive rubber strip between the glass of the display & the board it is attached to. Over time this rubber can leak an insulating compound onto the interface connection that can, at times, be removed by removing the strip and gently rubbing it with a clean soft eraser. Be gentle as it can be fragile & easily damaged. This was an effective repair in the early days of these displays.0

Most of the time, fixing a slow iPhone could be as simple as freeing up space on your device.

Whether you stepped on it, leaned on it, dropped it, closed it on your keys, or subjected it to extreme temperatures, one thing’s for sure: right now you can barely see anything on your laptop screen!

In all these situations, the screen itself has been ruined – the glass cannot be repaired, and humans are incapable of fixing the tiny connections that have broken.

But all is not lost!Replacements for PC laptop LCDs are usually fairly inexpensive – around $150-200 in most cases.  We can find the perfect matching part for your screen and install it in short order (our primary vendor is in Apex and can usually get screens to us the next day), and all will be as good as new!

We also can replace Apple MacBook displays!  We source entire display assemblies from a vendor in Virginia which means you can get your Mac screen replaced in as little as 24 hours! Try getting service that fast anywhere else!

After a long, hard day, you finally sit down to catch up on your favorite show. But when you hit the power button on your remote control, your TV screen stays black! You try pressing the remote’s power button again and again from every angle, but still, your TV has no picture. If this sounds familiar, you’ve likely fallen victim to one or more TV screen issues.

What causes a TV screen to go black? Software issues, loose connections, or backlight problems are usually behind black TV screens. Learn about each of these causes and get tips for troubleshooting them so you can get back to relaxing with your favorite TV shows, movies, and video games.

If your TV screen is black and there’s no sound, you’ll want to check for an LED light or a small indicator light that tells you the TV has power. If there is no power to the TV while it is plugged in, there may be an issue with the outlet or fuse box in your home. However, if the TV is on but the screen is black, the problem could lie with your TV’s software.

Unplug the TV from the wall, and, if possible, remove the power cord from the back of the TV to perform a soft reset. Wait 30 seconds, and plug the TV back into a working outlet to test it again. If you’re still having screen issues, you might want to bring in an expert — they’ll know how to fix your TV’s black screen.

If your TV screen goes black but the sound still works, the first thing to check is the input source to ensure it is turned on and operating correctly. This includes external devices like cable boxes, video game consoles, laptops, and streaming devices. Once you’re sure the input source is working properly and you have the right input settings, check the cable connections. In many instances where the TV screen is black but the audio works, poor cable connections could be the issue.

Whether you’re working with an HDMI cable, RCA (usually yellow, white, and red cables) set up, or another type of connection, you need to ensure the cables are seated properly and firmly into their connection ports. With a good connection, the cable shouldn’t feel loose or easily disconnect when pulled on or moved around. If all your cables have a snug fit but the problem persists, try connecting the device to another TV. If your TV screen is still blacked out, you may need new cables.

Some TV displays, such as LCD screens, use a backlight to illuminate the picture. If the backlight burns out or stops working, it will result in a blank TV screen.

To check your TV’s backlight, make sure your TV is on. Then, turn off the lights in the room and shine a flashlight on the screen. If you can see a picture with the flashlight, then your TV’s backlight is likely burnt out.

While you might be eager to learn how to fix a black-screen TV, a broken backlight does not come with an easy solution. The backlight will need to be replaced, and it’s best to get help from a professional with this task.

If repair costs are outside your budget or not worth it considering the age and condition of your TV, you may want to consider upgrading to a new smart TV. When you purchase a new TV from your local Rent-A-Center, you’ll enjoy free product service and repairs for the life of your agreement as part of our Worry-Free Guarantee.

You’ve run all the tests, checked all the ports, and ensured your TV has power, but your TV screen is still black! There could be a more complicated (and expensive) issue, so it might be time to ditch your old TV for an upgrade.

Rent-A-Center makes it easy to own a new TV, like an LG 65″ 4K UHD Smart TV.
