Vertical rainbow lines

[Pjaska]

@zeno i tryed this same gamemachine and other tv and there was no lines. I would like to understand what the logic is becouse they mostly appear on black screens but as you can see in the photos: other pic has it other one dosnt, both have black backgrounds...

Tube problem it definietly seems to be and nothing probably going to fix it. Good thing is that the lines appear just rarely on some screens. Maybe its coming out of closet
