Good evening all. I have picked up this set that was reported to be dead. When I powered it up, it worked perfectly for a couple of minutes. I then powered off/on and the picture is no mo. The backlight is working fine as is the sound.
Test pads on Tcon are all very low until I pull the left side ribbon cable, the voltages then come up and the right side of the screen is working.
Can't see any shorts on the left side LCD driver board (if that's what you call the long thin pcb that hangs from the LCD?) There isn't much to check on those boards, looks like just sm caps and maybe diodes.
Bad panel? Anything else I can check before I strip it? Cut left side COF tabs perhaps?
I'll load pictures if required.
Many thanks
