Hi,
Your tv has problem with the back light inverter. As you didn't specified the model number its not possible to know is it back light or CCFL one. How ever i have added video to know hoe to find the inverter check it.
Sounds like a main board that controls everything on the screen and then some.
Since a LCD do the flashlight test (what I call it) : darken the room as much as possible and with a flashlight and the set on look closely at the screen, see a very very faint image of the picture or not?
You could be having a backlight malfunction. Easy way to check is: While tv has sound Shine a flashlight on the screen Look very closely and see if you can see a faint image on screen
Does the lcd screen have a glow to it ? Or is it really dim if u get real close to screen u can see images moving ?
it it has a glow to it you panel lighting is fine but you control board is bad. If you have a dark screen and see faint images you panel back lighting is out u can check the power with a meter at the connection to inverter board on panel.
