I have this board from a macbook with flexgate (disturbed picture). Customer continued working with it till it gave no picture anymore.
EDP_INT_AUX_N 20 ohms to ground with everything disconnected. External display works, so definitely a defective CPU.
I have also a donor board from exactly the same macbook, also (I hope) a 2,9GHz i5 from 2016. This had a burnt C7901 (PPBUS_HS_CPU), which literally burnt a hole in the board. Normally this CPU should be fine.
But it's a 820-00239-09 board.
On the CPU of the donor board, I can read two numbers: J619B764SR2JK (horizontally) and 00014 (vertically)
The target board's CPU is listed with J625C284SR2JK (horizontally) and 05621 (vertically)
I don't have experience with this Intel numbers. Are that serial numbers, date codes or partnumbers
Should it be possible to place the CPU of the donor board to the target board?
