Eisengrim Posted March 10, 2022 Share Posted March 10, 2022 I recently got a CX-53 trak ball for my 5200 and the keypad and ball work, but the start/pause/reset buttons do not. I've cleaned the contacts on the original joysticks' flex circuits with some success - is a similar operation possible with the trak ball?

Eisengrim Posted March 11, 2022 Author Share Posted March 11, 2022 Well I went ahead and gave it a shot. Opened it up, and it was remarkably clean inside. Took the upper PCB out of its brackets and cleaned the contacts for the start/reset/pause buttons. Didn't make any difference at all - those buttons are completely unresponsive.

Need to verify the cable wires those are attached to and check for any breaks within the cable harness as the next step possibly. I'm stating this with the assumption that you are able to play other games okay using a different controller yes? Quote Link to comment Share on other sites More sharing options...

Yes, the 5200 works fine and I can play games like Missile Command with the Trak Ball by starting it up using a regular joystick and then switching to the Trak Ball. The ball, keypad, and fire buttons work. Only Start/Reset/Pause don't work. Quote Link to comment Share on other sites More sharing options...
Eisengrim Posted March 15, 2022 Author Share Posted March 15, 2022 Starting to look like broken wires. I can't see anything wrong under the hood (exposed wires attaching to the PCB), but for all I know the wires have a problem deeper in the cable. I tested the pins according to the CX5200 service manual with an ohm meter and get nothing for start/pause/reset while I did get readings from the other buttons.

+-^CrossBow^- Posted March 16, 2022 Share Posted March 16, 2022 I believe the start,pause, reset all use Col 3 data input to register them. So the issue could be the wire going to pin 4 on the controller port in this case. If normal controllers are working, the issue has to be the wire or a break in the PCB for that main signal line for those buttons. Quote Link to comment Share on other sites More sharing options...
