Motherboard has no brain 820-00164-A
Hey guys, I am trying to fix a Macbook air 11 inch motherboard.
Fan spin and green light but no image. All power rails are present and I replaced LCD connector and LED driver.
PCH signal present etc seems CPU dead even though the board will charge battery.
I spend quite a few hours already on this board :)
If you have any ideas or experienced to share.
I have also replaced the bios chip still no chime or image.
regards,
Sebastien
