I was getting random resets during game play. Researched it and found a lot of information about the 5volt variance that can cause these random resets.
I reflowed the connectors on my original power supply and reseated the wires in the plugs. My resets significantly decreased to happening only occasionally. But after a restoration, I didn't feel like living with this. So I bought the capacitor rebuild kit for the large display Sega Power Supplies. My soldering skills are above average (so I thought, definitely will reconsider). After installing the kit, board work is quite a bit different than switches and coils, my Power Supply didn't even boot up the game. But I was thinking this was going to happen.
So I ordered a new Power Supply for large displays from Marco. It came in and it worked perfect! Everything good, so I thought. After a few days of games, my daughter says "Dad, the screen's blanking out again and resetting". I pressed on the CN6 plug and the game started freaking out. Random call outs and sounds, so I figured I found a loose connection.
I pulled the plug, reseated the wires, and plugged it in several times. The game boots normal, lighting comes, I hear "Suppose we flip" but then the craziness starts. The game actually starts, switches begin firing, even "Slam Tilt" comes on the display (I do not have the slam tilt connected). I tried a factory reset. Same issues occurring, but instead of the game starting, the credits increase, then a game starts and more credits start flashing on the display as if someone constantly depressing the start button.
Any thoughts or advice? Thanks
