Hello, Im having troubles with a EAGO chassis, model: 53210. when I turn it on everything is normal, there is no horizontal line but I have to fix the image so when Im adjusting the V. HOLD and Im reaching to the image, the horizontal white line shows on the screen. Ive already change the horizontal transistor (c4742 & bu2520af), the IC (an5521) and the vertical transistor (d1138). What should I do? Thanks.

the screen is showing this image, I made it but looks like this
Ive already adjuts the vertical position but it moves a little, not enough

oh yeah i think i understand what you are saying now,when you adjust the vertical size to try to fit the screen then you get like foldover effect with lines
if its the original tube for the chassis then i would say look at any capacitors around the vertical deflection ic
