Re: panasonic tx-55ax630b no backlight

Same tv.
Same problem.
After trying changing the 3 boards I gave in and took it to a local repairer.

He found one faulty LED. he changed this out and the TV was fine for a week or so. Today
Apparently this TV will detect a return current outside the tolerances specified for the back lights, shut down the whole set as soon as it detects it and do a slow single red light blink to indicate this. Maybe something to do with the control needed for the fancy adaptive backlighting where it can dim areas for better...
