I re-capped two old Cambridge Audio D500SE cd players. One version 1.0, the other version 2.0. The main difference is that the servo mechanisms are by different manufacturers. Version 1.0 has a Sony chipset and I've forgotten who the v2.0 chipset manufacturer is. The units now both have weird intermittent problems. Both occasionally will show that a CD is playing but there's no (analog) audio out. The v2.0 worked just fine for a couple months and then started having these problems but the v1.0 unit had them immediately. With the v2.0 unit, sometimes the disc isn't recognized and is spit out again and rarely the front buttons don't work though the remote does. I've tried cleaning the contacts on connectors but that doesn't cure the problems permanently. Oddly, if I hit the power button while a disc is spinning and then restart the player it will usually work normally again for a while.
I'm guessing that one of the replacement caps is too different in ESR from the original. I used good lowish ESR Japanese caps to replace the originals. I don't have the service manual so I'm at a loss for what to check to find the source of these weird problems. Does anyone have any advice?
