(Also, I'm not exactly good at electrical stuff, and I'm much happier poking around the mainboard with a multimeter than the CRT stuff, especially when powered up. Schematics with 10kV written on make me very nervous) But I'll look specifically at the things you mention if the timer repair doesn't bring it to life again.
