| Macintosh Color Classic recap concerns | |
| Posted by: agent_js03 on 2016-06-10 07:22:29 Hello all, I recently bought a Macintosh Color Classic from a woman who had a classic mac collection she was trying to get rid of. I didn't pay very much for it, fortunately. She assured me that it was tested and working. When I got home I tried to power it on (yes, I used the keyboard) and found that I had been lied to. Oh well. I went through the steps to try and get it working, no go. When I looked at the board, I saw very clearly that there are signs of capacitor leakage. So I ordered some tantalum capacitors and busted out the soldering iron. Right now I have begun removing old capacitors from the board, haven't begun soldering on the new ones as the capacitors haven't come in the mail yet. When I removed C9 (near the "front" of the board where it plugs into the wiring harness) I noticed that the top layer of the board has begun to chip away. When I removed solder from the pads that the capacitor rested on, green chunks of the top layer blew away. I cannot tell if any leads were lost. I don't think so, but I am not sure. I am wondering if anyone has closely documented their recap experience with a color classic and happens to have pictures of the board without the capacitors on them, so they can show me what that part of the board is supposed to look like. Maybe I can gently expose the leads and solder a wire back into the place where they went before. I will try to recap as planned... If I don't succeed, I guess I'll have to keep my eye out for a new logic board. 🙁 It's hard to find one on eBay for less than 50 dollars these days... | |

| Posted by: agent_js03 on 2016-06-10 08:44:31 Thanks bibilit... I was wondering, could you take a high res photo of the capacitor section in the bottom right corner of that photo? I need to be able to see the leads in the circuit... | |

| Posted by: agent_js03 on 2016-06-14 05:00:48 bibilit, that is perfect. Thank you very much. It looks like the leads were probably not interrupted on my board. I will proceed with the reccap as soon as my capacitors come in the mail... | |
