The fault is with its main power regulator section circuit itself. Check all the electrolytic capacitors there. Replace them. Replace the main filter capacitor too.

If this is a tube type or crt type. Your vertical circuit has a problem. Could be the vertical IC loose connection on its board. Or the vertical ic itself is faulty. If just resoldering or refluxing of its pins doesn't help check some minor cmponent within vertical circuit. Or the vertical ic is defective already.

If your not inclined on electronics never do the repair itself, nasty voltages might caught you.

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.
Good Luck
