I have a dead CBM 4032.
I do not know much about these. I have read several web pages about repairs, but alot is over my head.
First thing I did was disconnect the PSU and test with a multimeter. It shows about 10.3v on 2 lines, and 40v dropping to 0 on some others. Though I'm not sure sure what pins to test with eachother. I just touched red to blacks, then browns, then blues.
From my reading, I think the 10.3v should read 12v. So I assume the big green cap needs to be replaced. Y/N.
If have read my other help wanted posts, (thank you all!) you know I do not have a EE degree, nor a O-scope, just my cheap Multi-meter, and a logic probe.
If the main cap is bad, could you provided a link to the correct digikey item to order. (When I order, I get the specs usually right, but get the wrong size, diameter, heat wrong and then blow something up after soldering it in) (but my soldering skills are getting better
The main board looks to be in good condition, as dose the case. Little dust, no corrosion. So I think it has been stored in a good place. Things I should check?
Thanks
