Hi everybody,
i have this board, i change the GPU 216-0810005 by new one.
The display work normally in EFI with no error but don't start on ASD and on the system (before repair, display with bad color, vertical line, etc...).
I remove the chipset, reinstall new one, same problem (before i verify with microscope each pin on the board no problem all in good state).
I make this repair some times with no problem but on this board i don't understand.
Do you have any idea?
thanks

Screwed up VRAM, knocked off component, damaged PCB, crap GPU, bad soldering. One of those, no way to tell which.

Was the old GPU also 0005 or 0084?
