Yes you could look for the capacitor that is leaky, probably in the 200v line, or you could just open back and turn up G2 screen control on the Flyback. You have Screen and Focus on this black transformer with a long anode lead going to the picture tube of set. Becareful, High Voltage!

It sounds like a vertical deflection problem. You mentioned you had a white HORIZONTAL LINE in the middle of the screen. If this line runs from left to right across the screen it's in Verticla deflection. If it runs from top to bottom, it's in Horizontal deflection. I am assuming the problem is a Vertical deflaecion problem. The repairs necessary are most likley to replace the vertical capacitors or the verticla deflection chip.

This is caused by a bad capacitor in the vertical circuit. If you can solder, you may be able to resolve this yourself. If you wish to attempt this repair, please update this and I will provide additional details and instructions.

If your picture has collapsed to just a horizontal line across the center of the screen, this indicates that your Vertical Output circuit is bad and needs to be serviced by a qualified technician. I hope this helps and thank you for using FixYa!
