Quoted from beltking:Need help. I went over all cables and all are good but the menu/volume button on coindoor doesn’t work at all. Any suggestions?
I checked everything. The cable is plugged into the buttons on the bottom and into board. Also the lockdown light isn’t working.
Check the harness/cable that connects to the coin door board, with the power off.
Pull the connector and look to see that each pin is seated inside the connector fully and isn't mis-crimped somehow.
