Nice pictures.
problem: vertical IC. Probably a bad electrolytic capacitor.
Does it make any difference if it warms up for a while, or if you tap on the screen with the side of your fist?

Horizontal lines present from power on. No matter what source, does not seem to change much at all after on for hours.

Light to very firm "tapping on screen with the side of fist" does nothing.
Do I need a BFH? (Bigger Hammer) LOL!

Can I locate problem and replace component electrolytic in Vertical IC or is it time for $$$hop or junk?

Thanks...

Check: C555; C502; R502 & IC500.
Be sure IC500 Pin 2 = 13.4VDC & Pin 4 = Minus 17VDC
