Mac Pro 2013 a1481
Hey wonderful that you got the system booted .
I came across this thread in the hopes to find a schematic for the a1481 , I believe they don't exist . Please correct me if I'm wrong. Also if you'd post them i'd be greatful .
i have a Mac Pro 2013 a1481 with led 2 , 3, 5 remaining on and then the system tries to boot to s0 , with led 6, led 7 ie s0 and s4 turning on simultaneously and Turing off .
I don't have a doner board nor schematics … hence trying to figure out where to start to probe . I've checked all connectors and cables which a seated and working fine... -

Re: iMac 27” a1419 emc 2806 MLB # 820-4652-A boardview and schematics required
so I have taken a picture of a affected area that is behind the GPU . I have also colour coded the pads as best as I can . But due to no schematics I can not figure out what components are missing .I can see at least 6 dudes(caps /resistors) missing.
if someone with the same machine can share a picture of the same area or share values of the components it would be very helpful.
I'd be very grateful to that person.
thanks in advance....Leave a comment:
