Reply to VCI-100 Red Jog Wheel!

Hello everyone, I'm having a problem with my vci-100 right jog Wheel it's red ALL the time, just like I would be touching it constantly. Anyone know what could cause this or how the touch sensor works? I have open it and it's pretty simple, but I don't seem to understand how the sensor works... Is it possible to fix it or do I have to change it, and if so where can I buy the sensor?

Thanks
