I live in France and I am the (happy ?) owner of a ... dead Classic Color Macintosh... So please sorry for the mistakes I could write in the text bellow.
Well this CC comes in pretty well condition, with all the stuffs, manual, floppies for installation etc... But the fact is that it doesn't start.
Everything has been checked (new battery, fuse, adb keyboard, adb cable) but ... The green & small light on the front panel is off.
The strange thing is that when I remove the mother board, and then press the power switch, I can ear a 'boing' sound that seems to go to the screen. I can even ear a small sound, (like a capacitor) especially when the power cable has been disconnected for a longer time.
And so if I insert the motheboard (with the power switch 'On'), this 'powersound' disapears...
Thinking that it was the motherboard and bad capacitors, I have replaced all of them. There were indeed small very small marks of leakage aroud & behind the caps (the surface around is not as shiny than the rest of the board, that looks +/- new).
But the result is nothing : definitely the only thing I got is a dark screen and the problem remains the same.
Any new idea ?
Thank you in advance for your help.
