Hi Members.i tryed applying external power to led backlights and got no current draw.checked power board connector and found pins 3,4 and 6,7 have continuity between them.I installed jumpers on the cable going to the backlights and it lit up.saw current draw and brightness of backlights was changing even though applied voltage stayed constant. Next step is to disassemble and replace faulty led diodes. I do have some extra led strips I can use for parts.since this tv is a freebe,ill go further than I would with a clients tv.RonL
