Hi all,
I hope someone can help me track down or troubleshoot this problem I'm having with my Wells Gardner 19k4906, which is located in my Ms. Pac-Man machine.
I've had this machine for about a year, and when I received it, it had some monitor issues. Specifically, it would randomly flash a bright white on the screen for a mere second, and then go away. It wouldn't happen very often, but maybe once or twice during a game. One day, after power on, and a 15 second warmup cycle, the screen displayed what you see in the photo. Powered off, back on, same thing. Then it quit, and was normal.
So, I decided it was time for a cap kit. So, I ordered one from Bob Roberts, and pulled the chassis, and installed the cap kit. Everything worked just fine, but, the problem persisted. Today, the monitor seems to be stuck in the mode in the picture, of what you see after a 15 second warmup. The monitor looks great prior to then.
I've checked the caps--they are all in the right orientation. Being that this problem occurs when the monitor warms up after about 15 seconds, makes me think it's a component of some sort causing the issue. Anyone have any idea?
I've attached photos to this posting--sorry, I was having a heck of a time getting the monitor to be photogenic. It's hard to see, but the background is blue-ish in nature.
I've swapped boards, so I can rule out the board being the problem. I'm certain the problem is in the monitor itself. I've also checked the connections, wiggled wires, etc, and I just dont' see anything physically wrong.
