Hi guys, we sold this mac 6 month ago to trusted client.
The machine was before used in our store for almost one year without issues. Never repaired before...
Anyway...
No post, No usb activity ,machine turns on , green and amber light , no fan spin but I assume that is normal on this model.
ALL_SYS_PWRGD drop to low once and then says high. Cpu get warm after a while.
Fan goes high speed on SMC bypass but nothing happens.
I checked all the SPI lines and all resistors and everything is OK.
Also tried a good bin file and another chip from same model of donor board.
No signs of liquid damage or whatsoever... Everything seems in good shape.
Any clues?
