Outrun 2 Monitor Issue?

[el_chiefo]

Hello everyone. I have an Outrun 2 sitdown arcade with a Sanwa 29E31S monitor. The game was working fine until after I moved it today. When I first powered it up, the game was working fine. After a couple of minutes the screen started to slightly flicker at the bottom of the screen (looked like an old tv when someone turned the lights on), and after a couple of minutes the screen started to flicker entirely. Shortly after that, the game went back to normal for about a minute and then back to flickering and it is now stuck on that with a bright line across the screen. I looked inside to see if perhaps something came loose when I moved it but I couldn't see anything evident. I also tried the adjustments, but nothing. Any recommendations? What should I do?  Thanks!
