Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should troubles shoot. Contact any service technician. The circuit will differ with models and versions.
Type in the brand name of your device, in the search box [at the top right] of the display window and the Search will start at once as you type in, and will show you all the related posts. It will make surf easy.

Hi Rechard,
Most probably the back lights have failed. It may be due to power supply failure or more likely the inverter failure. Please consult some TV tech.
Good Luck

LG 42PC!R Plasma TV turns on and then green led blinking with no ppicture and sound !


Your problem is most likely a fried circuit board. I always connect my good electronic to a back up battery. but your problem might have been storm or surge related, I would take it to a repair center and get an estimate.

I still have sound but get no picture on my DVD player


Chances are, that as in the issue with no sound/picture post, the Tv is the issue...dont fret, just refer to owners manual of tv, and verify which component/hdmi/s-video hookup it is and make sure you choose appropriate one on TV input setup. for more information refer to post of no sound/picture.

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..

Sanyo pm 8200 picture mail


I had the same issue once I scrolled down from the picture and found the picture mail had an option to view messege.

If that is not the case could be a programming error with your picture mail. You might want to contact your carrier for support issues.
