I finally found my way back here, and I'm already being greedy for help! Here goes:
What are common causes of Sega CD1 failure? Does it have an internal fuse or cb hidden deep? I started to crack into mine, but the old model 1 versions are kind of a pain in the ass to disassemble. About halfway into total disassembly, I still hadn't located a fuse or circuit breaker. I stopped there and left it alone. Does it have one? Is that a typical problem for the Sega CD 1? I've seen a LOT of "broken" Sega CD 1s at pawn shops and the like. Is there a "standard" problem and solution to the machines?
Thanks in advance for the info.
