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 computer off (by a menu entry), and after that, I tried to restart the computer again.

But the Mac IIci generates now repeating switch on switch off noise (a clicking noise, but very low/quiet, lasts 1/4 sec per switch on try and is repeated 1/4 sec again and again) and it does not start at all.

After another try, it even does not make clicking noise, just the the 3 led's are blinking in the same manner (while the power on key is pressed).

If I wait for more than an hour, it works again one time.

Any suggestions what is dead - capacitors ? Also the three diodes in row ? A replacement of the power supply did not help.
