Hi all, 


I am hoping someone on here with some experience repair an asteroids PCB can help me troubleshoot a minor issue I am having. My left rotate is sticking intermittently. I have replaced the buttons so I know it is a problem on the logic board but I don't know where to look. Every once in a way  the ship gets stuck rotating left and then i can rotate right and it will eventually fix itself during game play. It only crops up once in a while.


Any ideas?

Could also be the wiring.  Try moving the wires a little when it happens to see if it stops.


Check edge board connector.  Remove it and check for frayed wires. With the power OFF for sure!

Its not a wiring problem. It only happens during game play. The test mode always passes fine for all buttons. Sometimes the left rotation sticks, other time the right button fails to turn at all. its very intermittent. Maybe one of the chips that handles the button inputs is going bad. thats all I can think of.
