I found a loose 32X in the basement today, take it upstairs, and test it out. No audio, no video, but there's a loud buzzing (almost crying-like) sound coming from the system. I'm thinking blown capacitor but I'd like a second opinion before I put some time aside to disassemble it.

84000, non-revision model. I remember reading about some issues with these but it's been a while since I've had to work on one. Tried with a Model 2.
