aargh!
The capacitor was indeed making the monitor act funky. I replaced it with a normal through-board one and the monitor now degausses and I get HV. BUT that was not the problem. It's now doing the same thing it was before: degausses, then the power light starts blinking yellow (because horizontal collapsed). I feel like crying (metaphorically, not literally). I replaced 6 caps in there, 3 were borderline and 3 were way off the correct readings. One was bad on the neck board, two were bad on the chassis, two more on the chassis were borderline, and one on the neck board was borderline. These are all quality caps too, there were mostly Rubycons and Nichicons in there. Nothing looks burnt or damaged in there, trust me I looked. I've become quite familiar with this monitor (literally spent all weekend working on it). I still haven't checked ALL the caps in there, probably half maybe. All HV caps (there were only 3 brown caps in there) checked out fine. So did the huge filter cap.
Q902 and Q901, both are three pin devices on a heatsink, don't look burnt or damaged in any way. Should I rule these out, or could they be bad anyway?
I will try and test the rest of the caps in there today. Any suggestions? You guys are my only hope. I really don't want to pitch this monitor, I really like it and it's got dual inputs, one VGA in the front. It comes in handy all the time because my friend regularly brings his Xbox 360 over and we play on xbox live. I doubt I'll find another computer monitor with a front input, let alone one that's also a Trinitron.
