Hi everyone. I have an opto switch that is not working on my Judge Dredd. The switch number is 72. When poking around, I noted that when I touched a bundle of wires, a whole row of switches goes out. I've attached two videos... one of the connectors and wires, and one of the DMD display of the messages during the switch test.
I'm new to this, and am sure hoping there is one bad wire or connection! I noted that the opto switch that is causing problems with the gameplay (#72) is in a different column then the ones that light up when I touch the wires (62-67). But, maybe the issues are related?
Does anyone have any suggestions of things I should test, etc.? ANY help or suggestions would be appreciated.
