Turn on the set and get a strong light and bring it up to the screen. Do you see a faint image on the screen? If you do, then your backlight has failed. It may be one of the many lamps, or the inverter circuit or the power supply for the lamps.

The colored lines usually indicate a broken screen from an impact...unlikely unless someone hit the screen just before the picture went out.

LG LCD Tv has sound but no picture only colour vertical lines. Can be fixed?


If your screen has a picture in the left corner with a small square with lines on it but still has sound...try this....

unplug your TV itself from the power source, then hold down the power button on the tv itself for 1 minute, then release.... Plug the tv back in and see if the issue is resolved. I just called LG customer support and a woman walked me through this process and it fixed the issue !!!! Hope this helps..

Intense white & coloured horizontal line on black background on startup


I wouldn't attempt as the capacitors on a tv store around 25000 volts this is more than enough to kill you and they keep there charge even when the tv is off. Either take it to a repair shop or put that money towards buying a new tv - Do not even attempt to open the tv. (It sounds like maybe a tube has gone or the electromagnet that makes the beam move vertically is gone.

LG PLASMA TV WITH COLOURED LINES OVER SCREEN


If the Video (Picture/Pix) is gone but you can hear the Audio (sound), then it could mean the YSUS PCB Assembly is gone/kaput/finish. Can replace the PCB, not repair the PCB due to timing circuitry involve. Cost maybe roughly $500 depending where you located. The PCB is located on the left hand side of your TV when you are facing the back (Back open). Might find 3-4 brown flex membrane connecting to the plasma panel. The PCB has a silver or black aluminum heatsink (big) on it.
Good Luck.

Sylvania 27 inch stereo flat screen tv


This problem sounds like a short inside the picture tube itself unless a driver transistor failed that drives the red gun in the CRT. You may have to take it to an authorized repair facility if the picture tube is still in warranty.

Vertical line on KDL-32s20l1


You'll get this abnormality some times due to the signal if you're watching regular analog picture and you have your TV set on full screen, the TV will stretch the picture and you will see more defects than if you're watching it on normal picture. But if you are seeing the same problem when watching HD picture it needs to be serviced try this link I found: http://www.moniserv.com/doc/lcdtv.html
