I have a scared stiff on location. Getting bad trough opto message on boot and cycling balls out. Replaced the power driver and it worked for a couple hours then did the same thing. Replaced the trough optos, cpu and 16 opto board under the pf. Other 3 optos that share the trough on the row work. Trough optos show a glow when using cell phone camera so they getting 12v. Get tone on the green-orange wire from the cpu to the 16 opto board and getting tone from the connectors from the 16 opto board to the trough board connectors. Any ideas ?
