Alright, I just checked the pins on the base of the CRT while it was turned on and everything was plugged in. I removed the connector enough to wiggle a multimeter probe in there while maintaining electrical connection.

Most of the pins seem to check normal, but pin 3, which is listed as 260V boost, is showing closer to 90V. Could low boost voltage be causing my problem? I'm not actually sure what it does, but it doesn't seem like there should be that much variance. It looks like that's coming off of a lug on my flyback, and going through resistor R79. I suppose my next step is to verify that R79 hasn't drifted above tolerance.

I remember hearing that, when testing a resistor, the correct procedure is to unsolder one of the leads and isolate it from the circuit. Would that be correct in this case?
