Looks like this monitor has spend some serious time in water. I have all the luck. The grounding strap was even rusted off, but other than some mildew the boards didn't look too bad.
When I got it, I had no picture but I did have neck glow, deflection chatter and the spot killer was coming and going. I'd lose deflection chatter when the spot killer came on. No HV. I only ran it for a few minutes like that.
So after recapping (and reflowing) it I had no picture, but I did have neck glow, deflection chatter and the spot killer was off. Didn't look like I had much going on in the HV department either. I cranked the contrast all the way up and could see a VERY faint hazy glow then I turned it off. I noticed Q708 got pretty hot after the reflow but before the recap so I replaced all the frame transistors with known good (but old) transistors. I assumed I'd probably nuke one of them if there was still an issue with the deflection board. Looks like there is.
Today I powered it back on. Neck glow, deflection chatter, kinda blinking spot killer and no HV. Getting 35V off pin 1 on P500 so I assume the HV section isn't completely dead. Q708 got nice and toasty and before I could power down, I smelled the blue smoke. Didn't see any fire, but R718 and R713 are burnt. All the fuses seem good (F700 has a 3A in it it though - supposed to be 2A - maybe an old "fix"). The two burnt resistors aren't all that bad so it's possible (but doubtful) that I missed them. Of course the only picture I took of the board is the one at the top of the thread, and each of the components in question is blocked.
So what's SOP? I'm going to start metering around the 700 section looking for shorts (I believe I need to remove the transistors from the circuit to do so, right? Anywhere in particular I should focus? I checked DB100 per Dokert's instructions in another thread, and it looks correct so I think that guy probably works.
At any rate, I think this monitor is going to be beyond my newbie skills

There's just too much going on with it!
