SOURCE: LCD TV SCREEN PROBLEM RED HORIZONTAL LINES OF DOTS ALL OVER SCREEN PLEASE HELP

I unplugged the TV and now the picture is back.I read that the LCD's are vunerable to static build up so unless my daughter is using her TV I unplug it.

I was thinking about getting a large LCD for the family room but I'm not going to until they improve on this technology.

Good luck to everyone!.

Cheers.

Sorry, this has no easy fix. The good news is you do not need an LCD Panel. The bad news is the Video Processor has a problem.
This TV has x3 Boards. The one you should replace first is the one in the middle. If this doesn't fix it, try the one on the right. The Part #s are on the Boards if you wanna try ebay.

If the screen works for a short while and then completely fails once the TV warms up you have a problem with the main unit video board or the LCD control logic board. Most often if the picture cuts out but audio continues to work the logic board is over heating and should be replaced. However if the picture cuts out and audio shuts off as well then its your video input board.

JVC LT-50A330 TV. Sound but no picture. Screen is blue


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

JVC 32 inch LT-32DY8ZJ T turns on...shows green light....then turns to standby then back on then off again. Can this be repaired?


Good day..


That problem is usually cause of bad capacitors on the power supply section..

As you stated your TV works fine and after a minute the red light comes on...

That symptoms is cause of bad capacitors..Normally bad capacitors can check visually if the capacitors look like leak/bulged on the top that is the indication of bad one but not all bad capacitors are bulged some are not so in that case you have to used a special meter called capacitance meter..

This is the sample picture of bulged capacitors:

Red squiggly lines all over my Panasonic Mutlimedia HDTV


I've seen this sort of effect on Sony, Hitachi, and Mitsubishi LCD projectors too. Its a defect in the LCD panels. The issue here is heat. The high temperatures around the lamp can go even higher when the ventilation system of the TV has been clogged by dust and other particulate matter, especially cigarette smoke. The lamination of the postage stamp sized LCD panels is damaged resulting in deformities which affect picture quality and uneven color rendition (blotches). Some manufacturers have helped their customers when approached and others have been compelled to because of class action lawsuits brought by angry consumers.
