Ok, I put in a new doorknob, but that didn't do it. i also replaced a few bad resistors, no effect.
The P-P waveform is still 60ish volts.
The raster is square, as brightness goes up, it blooms, loses focus, then goes away totally. There's no picture at max brightness.
Brightness settings affect the drive waveform slightly.
Also, the waveform's a pure sawtooth, no little squared portion.
I'm suspecting either the waveform's wrong, or the flyback's bad
