Hello everyone,
First time posting here so apologies if this is silly!
Mac Pro 6,1 that no longer POST’s or shows Video out. Was fine on boot and then restarted into safe mode without holding shift.
After a quick NVRAM reset Mac no longer POSTs
Tried new RAM no joy, Replaced coin battery no joy, tried all video out options, diags LED indicated bottom LED PCIE switch status flashing indicating V1 or V2 mode (been trying to find out whether this is indicating why I can’t get USB keyboard to register!)
I have tried replacing both GPU A and B but honestly there is a chance these cards are defective as well since I cannot test them currently.
Anything I am missing?
Thank you for any information that can be provided!
