'Lights Up' But never shows video & shuts down: Likeliest issues?
Powers on, (the input panel lights up and the fan spins), but, never shows video … and eventually just shuts down.
(I actually attempted resetting the PRAM but was unable to get it to do so, thus, never got a chime out of it … but I bought it from a good customer ‘non-operative’ who’s at LEAST savvy enough to attempt swapping memory modules.)
I’ve disassembled it, and actually have replacement CPUs (and RAM of course) I could swap out to check what the issue is; the only thing I don’t have is a GPU.
Though, I’m curious, would this unit work with ONE GPU..? If so, I could disable each GPU while using the other to see if that’s the issue ….
Or, are there other ‘more likely’ candidate issues ..?
Thanks
