Bringing up an older Mac

Because I did that once, and the magnetic field from the disk interfered with the monitor. I had to make up a bracket to move the second disk an inch farther away from the picture tube. But, in my case, it was because the magnets in the disk were bending the lower corner of the screen - it wasn't moving wavy, it was fixed wavy. You're probably going to need to replace a couple of capacitors on the analog board. There's one particular capacitor that comes to mind as causing a different problem, it's nonpolar, so watch out. Is it like a 60hz kind of a wave in the picture, or is it more random? A wave through the screen, like a waving flag? It's been a while since I fixed one of these, so I don't remember off the top of my head. But I have a book at home, forget the name, but it's a Macintosh repair guide that has a lot of good info to help pinpoint failed parts. It has a purple cover. Anyone remember this book? This is going to drive me nuts all day. :) -Ian
