Your tv could have several problems, or one minor one, its hard to tell without seeing it, if you look through the back vents and the backlight is on ,it could be your lcd refractor board ,it could be as simple as a bad rca jack or rf jack depending how you have your tv hooked up , is ther a pic in any source mode,or are all dead, for example in vid 1 with a dvd player, if you get pic ,but in rf or reg tv no pic you may have a bad tuner or cold solder problems ,really hard to tell without more info sorry ,i hope i was helpfull
