Hello all I have a 15 month old 70' that died today, after a power flicker it flashes twice and twice(slow/fast) on the front led, i look forward to some assistance to fix this, there was a very similar problem here: https://www.badcaps.net/forum/showthread.php?p=430446
same voltage situation, 5 and 3v present but no 12/13, in both error flashing mode and led on(chan up/vol down) mode, and caps/fuses/resistors look ok. Here are some pics please advise as to possible diagnostics/fixes, Ie: can I bridge pins on PD connector to force power supply on?
some pics are attached to help. i will do some diode, rectifier and fet checking tomorrow, thanks in advance!
