lcd panel repair vertical lines pdf made in china

Ours is a Sony Bravia that is now over 10 years old. Several months ago we started noticing lines, especially on the left (our left) side of the screen. They’d go away after the tv warmed up. Then we started noticing it was darker on that side of the screen, but again, after the tv warmed up the screen would be normal. Then about two months ago it started getting worse and didn’t ever get completely better, even after the tv warmed up. So I watched some youtube videos that all talked about the ribbon cables becoming loose over time and to apply pressure along the top and see if that made it better, and if so, it was a loose cable and if you put electrical tape or something that would help keep the pressure, it would fix the problem. Hubby pressed along the top and sure enough, when he pressed in one spot on the left side suddenly the picture cleared up. Stayed good for about a week, then problems again, pressed again, fixed again. A week or so later, same problem, but this time when he pressed on it nothing got better.

So I decided to take the cover off and look at it better. As I was pressing on the tops of the ribbon cables that run down from the top of the frame, for a minute it got better but then suddenly there was a wide white vertical line, with a thin green one down the center of it, running down the front of the screen, and it was perfectly aligned with one of the cables. So now I still have the dark side of the screen, and some ghosting, and some lines, but now this bright white streak/line right down the front. Another weird thing is that if the whole screen is bright (like watching a show set in a snowy place) then the darkness even on the left side is basically gone, but if the scene is dark at all, that side is almost black. I don’t know if it means that particular ribbon cable is bad, or if something is loose, if things need to be replaced or what. It’s very frustrating as it’s been a great tv. Hubby wants to just buy a new one, but even if he does I would still like to try and figure out this one as it could then go in another room.

Performance issues may occur if there is any type of damage that is caused to the display cables or the LCD screen.

CRT (cathode-ray tube) television sets have gone down in popularity with the introduction of large screen, slim and flat LEDs and LCDs. However, there are many consumers who still have their CRT sets and are satisfied with them. But many problems often relate to the picture quality, picture color and clarity and sound quality of these CRTs. Sometimes the cost of repairing such common problems with CRT TV exceeds the cost of replacing it with a new TV.

No image is a very common problem with cathode ray tube TVs. If you are facing such issue then check the obvious things first i.e. verify whether your TV is plugged in correctly and is receiving sufficient power for operation. If the power is OK, then check the video settings (like brightness, sharpness, contrast and picture settings).If the settings are fine then there can be problem in the video cable and hardware. If the basic diagnosis comes out fine then it might be the time to call a professional TV repair person. (Picture Source: www.overclockers.com)

This is a very common picture problem with CRT TVs. It is usually caused by the failure of an internal circuit called the convergence circuit. The circuit has convergence ICs, which when go bad create the problem of bowed picture. Sometimes bad or faulty soldered-in fuses and resistors can also cause image distortion. A technician or a PRO can easily repair this sort of problem in-home. (Picture Source: www.justanswer.com)

Some time when you power on your CTR TV you see a single thin vertical line on the screen. The probable cause of this problem can be a faulty yoke with a defective or burned coil inside it. Other reason can be defective vertical ICs. The ICs may have lost contacts with solder joints because of the heat production during operation. (Picture Source: www.jestineyong.com)

This is not a very common problem. The most prominent reason is cathode ray tube failure. The minor crackling noise is due to high voltage arcing. The possible reason behind the burning smell is caused by insulation burn. In such situation, immediately unplug the TV from the power outlet. Call a professional TV repair person and get it corrected.

If you’re facing problems with TV not responding to remote inputs, first replace the batteries! If the TV still isn’t responding, there’s a problem with the remote. In this case, it is better to replace the remote instead of repairing it. Below are some CRT TV compatible remotes that we recommend.
