I have a Super CD-ROM? which appears to simply not do anything at all. No disc activity, no video from it, nothing.
Before fearing the worst, I'm wanting to troubleshoot whether it's actually getting the signal to turn itself on at all.
It has been recapped, although I wasn't the one to start the process. It does appear as though someone tried it themselves, found it didn't work, then sold it on (and I knew it wasn't working when I bought it. But it was cheap.)
It wasn't too bad, but I've since redone it to my own standards. There were some traces I noticed as broken and repaired, but still no success, and I can't see any more obvious issues from a visual inspection.
The voltage regulators also receive voltage, and I am of course powering both the main console and the Super CD-ROM? unit together with a suitable power adapter (and splitter and other necessary adapters).
I've also tested it with both my white PC Engine and my Supergrafx; the latter being easy to get a direct video signal from, and pressing "run" just instantly returns "Please set disc!", suggesting it's receiving absolutely no response (I presume).
Does anyone have any information about how the Super CD-ROM? "turns on", and what traces I should check for continuity, and things like that? I don't have an oscilloscope yet, but I'll see about getting one if I can rule out it being an issue in connection or a simple component.
