Default Re: Sony Trinitron CRT TV fault

I think we have line output stage problems here. Firstly check the line output transistor for a short. Then if we're OK there turn on and see if you can hear (!) a rustle of EHT. If so then it can be the frame output IC loading the stage or, as said above, the LOPT.
Do also check for dry-joints on the regulators. Occasional capacitor failure, but not a go to on this chassis.

Funny how quickly you forget - saw it was a 32" and though 'oh, just a small one then'. Er, no, not in the days of CRTs!
