Hi all,
A little while ago I dug out my Mac SE FDHD and replaced it's dying hard disk with a much newer model. Afterwards as I was playing around with it, I noticed some strange horizontal lines in the video image, that look to me like an messed up sync signal. I made a video below which demonstrates the issue (sorry for my somewhat loud breathing).
Does anybody know what's causing this or if this might have anything to do with the new HDD, maybe its drawing more current than the old one and causing noise in the PSU? I'm a bit hesitant to open this thing up again since now the capacitors are fully charged and I'm recovering from an unrelated electrical shock, but eventually I'll psych myself into it.
