I have a Sigma Slot Machine SG-50B. It powers up and will play a few minutes then the displays go out and I can't do anything. (All the back glass lights stay on) Eventually it will turn back on and work again for a few minutes. I have bypassed the door switch, re-seated every connector and pulled out all boards and looked for cold solder joints. Everything appears to look ok. Any other ideas? Thanks!
