With the yoke disconnected, and the HOT installed, doesn't the circuit stop
oscillating? If so, wouldn't there have to be a measurable short in the
primary windings to ground for the flyback to suck the current? Are there
further steps I can take to isolate the flyback as the problem without
actually buying a replacement? Keep in mind that the flyback does ring ok
with my Dick Smith flyback tester.

Thanks for your reply.


Disconnecting the yoke, or even removing the HOT, has no effect on the
horizontal oscillator. Since there is base drive, you know the
horizontal oscillator is working. B+ goes directly to the flyback, so
if there was a short to ground it would overload even with the HOT
removed. It is possible for a flyback to ring ok and still be bad.
Is there any high voltage before it shuts down?
