I picked up a Mac Classic which didn't work. Logic board has been recapped and works in a different case, but the analog board doesn't do anything. No fan spin, crt, nothing. I did a full recap on the analog board, which took me 6 hours and was really frustrated that it still didn't work afterward. The person I bought it from said it worked 18 months ago, and when I went to pick it up, he turned it on again and it worked (showed screen with lines, probably due to logic board). What is wrong with this thing?
