The Jaguar is the only early 90s US console I don't own besides the NEO GEO. I want one for access to its library. I keep seeing "untested" or other seemingly minor hardware problem Jaguars on ebay going for what I would be willing to pay if I can fix it.

Is there a list of common hardware issues and tutorials to fix them online? Do most of the fixes involve simple capacitor replacements? I'd like to know, as I have no interest in owning Jaguar's for spare parts.

I am trying to minimize the cost of getting into the console as much as possible.
