Tron Joystick Down and Right stopped working
Well, this is the reason I prefer dirty working games to pretty ones that don't.
I had a great working Tron and decided I'd finally start cleaning it up. I started with the control panel.
The panel looks great now, and the new black lighting is great. Bummer that tron will not move down or right anymore. And after running the self test the P2 start button is also not working.
I traced the wiring and everything checks out, or at least I know I have working switches and there is continuity up to the two connectors that attach to what looks to me to be the sound/io board.
According to the schematic, pin 2 and 4 on J5 control Right and Down, respectively and pin 4 on J4 is the input for the P2 select. I don't really know where to go from here. I pulled the board and took a look for anything obvious and I don't see anything. Or maybe I don't know if I saw anything obvious. I really wish I had a dirty Tron machine to play. Any suggestion on where to look?
