How to determine if Flex Cable or Top Case defective?
my A1181 stopped working from now to then.
So I checked all voltages and stuff, everything was fine. The last try was the one I should have checked first: Just shortened the two pads on the board and voilá, everything is back.
So how can I see what I should replace - just the cable or the whole topcase? My multimeter probes are too large for a continuity test on the cable. But at least it looks good :)
Are there any tests I could do with the topcase or is there anything I can fix without totally damaging it? I see it is held together by just plastic "bolts" which would be destroyed. Am I correct?
I did not see a Teardown of the Topcase revealing its power and data lines so I’m curious if this is even fixable.
