New to fixing arcade games but have dabbled in pins. I have a Super Sprint I'm going to restore. It's been sitting for at least 7 years. It got parked when the monitor went bad (or so I thought). FYI...when the monitor quit working I could still hear the sounds of the game.
7 years later......I fire the game up and no monitor or sounds at all. After doing some research on hear I choose to pick up a new power supply and see if it would be the fix I needed. After hooking everything up I turned on the game. The LEDS on the boards lit for at least 5 seconds than shut off because the power supply went dead (nice smoke smell as well). I disconnected everything and started doing some testing on the power supply with a multimeter. AC 119.8 v in. Hooked it up to the power supply (nothing else hooked up). DC 5+ read nothing and the smoke began to roll. Thought I was behind a diesel truck.
I looked at the schematic for the game and noticed it shows +15 VDC on some of pin-outs?
OK guys. I obviously need a new power supply but does anyone have any direction to give a newbie? Thanks in advance.
