Color Classic wont boot

[fabian]

I have a Color Classic. It's behaving a bit weird.

First of all, when i plug it in it won't start. It seems like if I keep it plugged in for a few hours it suddenly starts working. I can boot it up by pressing the power button on the keyboard, but when it boots up, the keyboard and mouse does not work. I've tried many keyboards that are definitely working on other macs, but nothing seems to work on this one.

Does anyone have any idea? I already tried changing the battery.

Have the analog and logic boards been recapped and thoroughly cleaned?

 

[fabian]

No. I'll do that tomorrow.

If I take out the logic board it turns on perfect every time. Guess it could be recapping time for the logic board.

It looks clean and nice. I'll post an update when it's recapped!

As noted in many CC boot failure threads, the Egret chip near the battery tends to get the brunt of the cap goo. One it fails, that kills soft power. 
 

I have had success removing the egret with hot air and thoroughly cleaning under it. Soaking in IPA may be good enough, too.
