Excuse me for being sarcastic, but very often almost all problems which can occur are reduced to "capacitor" problems only. Many (almost all?) forgot, that there are also semiconductor stuff in it, and that thermal load will shorten lifetime of these components, too. Also, I suspected also the...

Meanwhile I've changed all capacitors above or equal 10µF on my Mac IIci board - no change, still the same problem. Seems to be that exchanging the capacitors does not solve all problems, eh ? Still working for the first time, but after shutting down and restart try, it makes only a "clicking...

Excellent explanation/picture - THANKS. I am expecting the problem only in the area of the startup circuit area, so I will start will the smaller silver ones in that area first, will then test it, but will not stop to replace the other caps even if the board is working then.

Really ALL capacitors ? There are bigger ones (blue, like a tube), smaller silver "pot-alike" ones and very small ones (orange, rectangular)... I have examined the whole board (upper and lower side), I found only one unusual spot, see attached picture...

Hi ! I own also a Mac IIci and I was able after a long time of "no use", to start into Mac OS 7. A starting chime sound was not produced, but I can use the Mac OS desktop and click on anything with success, except there is no sound/beep generated, regardless of what I try. I switched the...
