The retrace lines are all white, so it should be comming from all of
the crt's. The model is Hitachi CT4532, I have a pdf service manual for
it. And can make this available to anyone interested.

B+ was at 111 V Should be 110
Unsure of the crt voltage, or how to test that yet.

I am trying to get my hands on a ocsilloscope for further tests.

Im rather new to electronics repair, so I learn as much as I can as I
go. I have wanted to do electronics repair for some time as a hobby. I
have been reading, reading and more reading but know far from
everything



Well it sounds like you're off to a decent start, be real careful using
a scope on a TV, it's absolutely imperative that you use an isolation
transformer to power the TV for that. Good luck, projection sets can be
a real pain.
