Hello,
If you can fix it by yourself, there is a problem in horizontal circuit panel, you need to check that in series because the part appear visbly good but when tested by the exact tester you register busted. that should be replaced immediately. Check also the vertical panel parts of the circuit. but if hard you do the job you may consult the service center of your TV or the vendor of the TV.
ps. please don't rate me if you are not convince of my suggestion.
best regards, melnavz

The resolution on this was to check the surge protector the television was plugged into. Once we unplugged and plugged into another surge protector, the screen went back to normal and the appearance was great. We believe this was due to one of the resistors within the surge protector may have become faulty.

If the screen works for a short while and then completely fails once the TV warms up you have a problem with the main unit video board or the LCD control logic board. Most often if the picture cuts out but audio continues to work the logic board is over heating and should be replaced. However if the picture cuts out and audio shuts off as well then its your video input board.

hi,
check the ground connection of your house wiring. fist of all remove all the external input like set top box, cable connection, dvd etc from the tv. Then power on the tv and watch is the wave is there or not. if it there then ,if the tv power cord comes with three pin connector then remove the earth connection on the wall outlet socket to which you connect its power. the connect the power and switch one the tv.
if the wave will not appear then connect external devices (set top box, dvd etc) one by one and watch which device produce this wave in the tv. also check the ground connection of that device which produce this wave.
If all these will not help full then the SMPS power supply of your tv have some problem. Normally this type of complaint arises due to the faulty Main filter capacitor. you can see it in the power supply.. It will be the big capacitor according to others. Normally There will two or more. replace the same. will solve this problem. if you need any more assistance feel free to contact me through fixya
