I'm new here, so I'll start by saying Hi. I've got a Wells Gardner monitor that has serial # 19K7689, and it's set vertically in a stand up box (Capcom Bowling). My problem is that there are what look like horizontal shadows, or darker lines along the bottom of the screen. I have tried adjusting all the settings, but it didn't cahnge it at all. I was wondering if I should just get a cap kit, or if anyone has any other ideas. Thank you.
