Hi Guys,
Wasn't sure how to name this tread. I am dealing with A1466 820-3437-B board today which had extensive water damage.
After replacing couple caps and fixing traces around G3H it turns on, but it takes it 3 cycles to become stable and load into system, on bare board without any intervention after i attach the charger.
This happens every time i feed power: Turns on 0.4 - 0.6A draw for 2-6sec with no light on screen or matrix. Drops to 0.1A for couple secs. Then 0.4-0.6 again for couple secs and drops to 0.1A
Third time fires up and loads into system. After couple times looping like that switches off with 0.03A draw.
After third cycle, stays stable as usual system and can run for hours.
Between all these cycles no intervention by me.
S0 voltages fine.
Not sure what power sections to post.
Thanks in advance
