Using Retropie and I’m having an issue with down on the joystick. It works ok for a few minutes then seems to get stuck on. It’s not the microswitch as it all buzzes out fine all the way to the Picade board. The light doesn’t blink on the board like it does for any other button press, and if in a game the character moves as far south as it can go and stays there (left and right and all other buttons work fine). Wierd thing is, if I touch the connector on the board with a screwdriver/paperclip it seems to work again for a few minutes before going south again.
Bought a new 2 amp power supply today as I thought it might be that but still the same. All the wiring is sound and checks out. Does this sound like a dodgy board?
