customer dropped the set off stating that the picture would drop out alot before failing completely, i know these models are known for having crappy lcd panels and high failure rate for the t-con boards.

I had replaced the bad t-con board on this unit and replaced the fuse it blew on the mainboard, tv still has audio but no video just see the backlight.

DISCONNECT EACH CABLE TO THE PANEL DRIVE BOARDS ONE AT A TIME. IF YOU GET HALF A PICTURE THEN IT'S THE PANEL.
