IBM PS/2 Model 25 CRT - No High Voltage

[Jimmy422]

I got a scope and did some scope readings from the oscillator IC output, the output of the associated transformer, and the base of the HOT.

I’m assuming that since the output of the oscillator chip is not 15.75khz that it’s not outputting the correct signal? And because the HOT is definitely nowhere near that, that explains the lack of high voltage?
