I purchased an nfl blitz 2000 gold/nba showtime combo acrade machine about a year ago. It's been working flawless and up until recently the monitor was crisp and bright. The past week I've noticed when playing with friends that the colors start fading during gameplay (almost washed out) and the pictures starts blurring to the point where you can't read the words on screen. I adjusted the settings on the monitor and got the picture to look better. I thought I had fixed the problem by just doing that but just today the same problem arose. I have no experience in arcade repairs and looking to get some expertise on this. Is this a monitor issue or something else? Thanks!
