Could I get the PCB lay out of the boards in side of my tv. I need to trace down this problem. I have opened it up yet, so it could very well be a flat cable loose? cracked board? Or could it be as easy of a configure change on th O/S?
well let me tell you what it is doing.

not sure if there the same but the boards inside may be.
This sounds like the problem most LCD tv's get with swelled up
capacitors in the power supply board. look for circular cylinder shaped
parts rapped in plastic with writting on the sides, and metal tops, if
the top is rounded over, not flat, it is bad. replace them.
Sounds like a crack in the lcd panel or a toren or seperated ribbon cable on the lcd panel,could also be a bad memory board but not likely,dropping the remote could not cause this problem unless the remote hit the tv when it was dropped
yes you have to test voltage but you must plug it in and check the power supply board first, the most common problem for those things is the 24 volt transformer in the power board fails check it for 24 volt output first, then trace the power route from there and the component that the board traces lead you to that dont transfer power through it will most likely be the problem but start at your power suopply and work outward from there. mine the 24 volt converter or transformer blew. i have been looking for one for 4 months. there is a eeprom in the main video board that blows also its easily found, it turns the unit on from the standby switch. check it also with a volt meter. you cant miss it on the board.
thre are several components that can make a buzzing sound, especially a bad power component or capacitor. check the capacitors to make sure they are installed in the board correctly. the stripe on the cap must line up with the white mark on the board under it. remove the back panel lay the tv down on a blanket turn it on and see if you can isolate the noise component by ear up close. and visually check for swollen capacitors the top will be pushed up round if bad if good it will be flat on top. warning if tv is less than a year old make the place you bought it replace it. so you dont void the warranty.
