I have an issue with game images. I think it might be a motherboard issue, but I am not for certain.
Monitor is a Sharp 18" just fully recapped but with the old flyback.
With the dark colored screens I am getting slim vertical lines. These lines do not show up on the lighter colored parts of the games. On Mike T Punchout the background and some screens in SMB3, had colors change in Excitebike, Dr Mario, ect. But the menu screen (which is darkish green) is perfect and fully colored. I have messed with the flyback brightness, sharp control, and the 5 adjustments on the front bottom of the screen. I have not messed with the pcb color adjustments or the adjustments inside the monitor pcb.
I guess I need to post an image/video but I was looking for some tips on what to try tomorrow.
