Stargate : won't go up and player start sound is wrong.

On my stargate, all of the sudden today it no longer goes up. The interactive board is good...i tested it in my main stargate...the leaf switches look fine and making proper contact and are clean..i even pressed them together with my fingers for up and down and down works...up doesn't...i reconnected the cp molex connector, still no luck...all wiring appears to be fine.

Also, when u press player one and the game begins, the beginning sound is that of the enemy ship destroyed sound...it never did that either until today.

(Ps: i haven't begun searching for them, and will after this post, but anyone knows who sells the c-clips for the williams stargate joystick and buttons? I lost both c-clips while trouble shooting this issue....i searched for both for 30 minutes..i gave up)
 
So you swapped the interface boards and the board worked fine in the other Stargate. Take a volt meter and see what the input is on the interface board for the "Up" input. It should be 5v when "Up" is not pressed and 0v when pressed.

Next check the RAM and ROM in service mode for any errors. Double check the 5v power at each board.

I saw the washer and clips for sale here but you should be able to find them at a hardware store too: https://www.ebay.com/itm/Retaining-...031000?hash=item3acab60a58:g:P-8AAOSwq7dXFjwu
