I've got a Mac IIci board that has had a couple of problems, over the last year:
1) the board is mute
2) the board powers off, after approximately 30 minutes of use
I fixed the first problem by replacing all the capacitors in the sound section of the board, this weekend. Thank much to trag, for supplying the caps!
The second problem, however, remains. I've replaced every capacitor (PTH and SMT) on the board, to no avail. I've also replaced the power supply with a known-good unit. It seems to me that I have narrowed the problem down to only one possibility, though it's an unappetizing one: one of the SMT ICs on the board is heat-sensitive.
The problem is that it's really beyond me to replace a multi-hundred pin SMT IC, and, even if I could, the cost of the parts, when available, is prohibitive.
Does anyone have a last suggestions, before I consign this board, that I have worked so hard on, to the scrap/spare-parts pile?
Thanks!
