So - I'm working on a 4600 and take it from dead to pretty much fixed, take it out to my hot garage for testing, and it has a weird wave to it. The entire picture looks like it's doing a really slow hula. What weird is that as the wave moves up the screen, the colors change in the corners. I assumed it was a problem with the degauss coil, so I unplugged it with no change. Then I changed out the entire left wall (with the VR and power pcb) with no change. Then I changed the filter cap and the X601 diode with no change.
So while I'm standing there pondering what the hell is going on, i decide to do some voltage checks. I move the little fan (that's trying to keep me cool) sitting on my bench to the side - and the wave goes away.
Wasted half a day on that stupid shit...
