another update on this

left the tube on for 15 minutes and was gonna adjust convergence with strips, now it begins to lose color and the image zooms in extremely, only like 25% of the screen is visible and it's a zoomed in portion, not shrinking.

i'm at a loss of what happened, caps all look good, solder joints look good

im unsure if this is a flyback issue, there's no noise or whine/sparking, and iirc flyback would be the opposite where the picture shrinks, not zooms in

Any crt experts? pic rel is how it looks after like 10min of being on, on cold start it's better but nothing like how it was when it was 'fixed
