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.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement.

hi,

You have to check the back light of your lcd TV. All lcd screen have a back light to illuminate the pixels. you can conform is the back light is faulty or not by watching the lcd screen nearby. Watch can you see any image (negative image) on the screen. you have to look very closely. if you see any image on the screen then the back light or the back light inverter is faulty.

first of all check all the electrolytic capacitors in the power supply and back light inverter board.If available then replace these capacitors first.

You have to check the back light inverter board. Normally in lcd monitors you can see three circuit boards. power supply, mother board, and the inverter board. If available then try to replace the inverter board. There are high voltage transformers in this board. There is a chance for its winding get short. You will not get the transformer in open market. Try for the inverter board .
ok

Find a good 720p station and work from that. Don't try and make an analog station look good because with the new sets they just look terrible compared to a hd station. Your set will show you what it can do.

try swiching it all off then turn it back on to see what that does if still nothing it sounds the power mod is gone my advice to you then would to buy a new tv as the brand you have are two dear to fix.

does it flash when you switch on ?
take a torch shine into screen can u see pic ?
if so its the invertor board that controls the back lighting or one of the back lights have failed
