def something wrong, the crt cathodes should be about 175v all are at 220, so I am sure that is why its cut off. The driver transistors have the correct voltages at the base and emitter, but the collectors are also high (the collector connect to the cathodes).
I checked all the voltages from the ps all check fine. I will next get the scope on it and start checking waveforms, starting with the blanking signal.
IF i has an ESR meter I would just shot gun check all the little electros, but my cap tester only checks out of circuit so I would rather narrow it down.
I am going to have to pop for on of those in circuit ESR meters...
