trying not to die

Try turning down the "SCREEN" pot on your flyback. See if those white vertical lines go away.
This is all the way down

So prior was bad red pot and transistor on neckboard all good with colors.. but last part of the puzzle.
I get this effect looks like a voltage issue but not sure I know it's not the monitor as it was crisp on a test bench with different game and power running. Notice the straight likes on blocks are squiggly
Any ideas???

Monitor chassis includes neckboard, flyback, etc. But if you're saying it's an issue on the game PCB then ok

Yeah only reason I knows it's not related to the monitor because when we fixed it we tested on a different power supply set up different game everything and monitor looked great. Now I got it back home and colors are good but that squiggle is all left to fix about to try a new switching power supply
 
Wooo it was the power supply!! All good now. Thank you to all on the thread!!
