    820-3437-B no power, no green light

    Checled all. Every one seems okay except: R2013 is 70k instead of 10k R1580 is 60k instead of 100k

    820-3437-B no power, no green light

    No corrosion around. The two resistors in line (R6101,R6102) are fine.

    820-2879-b bad ram slots

    Neither. It works but when you flex the motherboard especially where the ram slots are it freezes/image distorts. Especially when I push on one of the corner of ram slots. I tried re-flowing the ram slots at 300C. It did nothing.

    820-2879-b bad ram slots

    This board seems to be prone to bad ram slots. Got another one but this time both of the ram slots gone bad. Is any way to fix at least one of them? Or is any other trick to make it usable?

    Yes during the quarter fan spin vcore jumps up to 1.8V.

    820-3437-B no power, no green light

    So I did change the ISL again. Nothing changed. Changed the SMC too. Still no green light with quarter fan spin. The current sensing seems messed but those resistors seem okay. Just to be sure: R7151 is around 3.5ohm instead of 2ohm respectively R7152 is around 1ohm instead of 0ohm. Could this...

    Yes it works without the keyboard. It seems that keyboard went bad.

    [SOLVED]820-2567-a turns off during boot

    Macbook white no liquid damage. Tried others rams, one ram slot combos, other battery, charger only, booted from external hdd. Still same issue. All S0 rails seem good.

    820-3437-B no power, no green light

    Tested with 3 IO cables. Same. Also I re-checked those resistors. R7005 was too high 300ohm instead of 20. Not sure why I missed that before. I changed it, now it is 20ohm as it should but nothing changed. There is something weird that might be relevant information: when i plug the charger in...

    820-3437-B no power, no green light

    Changed ISL6259 from donor board. Green light returned. Fans spinned up for 2-3 seconds. Then after some attempts green light went away. PPBUS_G3H is present this time. Those resistors seem okay.

    820-3115-B stuck on boot

    No liquid damage. During boot it freezes with blocks of text. Tried safe mode it freezes. Tried verbose mode it stops at a point. Tried the ram slots with no luck. Tried booting from external HDD: it shuts of the machine after a while. Any advice?

    [SOLVED]820-3462-A no green light

    Got this board from a mbp retina with liquid spill. (Very little corrosion) Did some work on it: R5095 pad nr.2 was distroyed so I connected it to R5092. This worked, the machine would work for a day then it stopped working. Hot rails are present. One wire circuit seems fine. Still no green...
