I unplugged the TV and now the picture is back.I read that the LCD's are vunerable to static build up so unless my daughter is using her TV I unplug it.
I was thinking about getting a large LCD for the family room but I'm not going to until they improve on this technology.
Good luck to everyone!.

This should be repairable. It may be the LVDS Cable or the Main board problem. The only other problem is the T-Con Board.

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
