SOLATOUCH Solar Control System quit working.
The LCD displays 'black squares' characters on top level, and nothing on lower level. Checked every point including FUSE, TRANSFORMER Outputs (15/30volts), ribbon cable continuity, voltage at LCD (4vdc), valve actuator operates when switch position is changed.
This controller includes two PCBs.
1) P/N 521604-Control Panel (Faceplate and Control Board)
2) P/N 521605-Power Board & Ribbon Cable.
I contacted Pentair Technical support who stated that it is a possible that P/N 521604-Control Panel (Faceplate and Control Board) may be defective. Online search for this replacement part has been unsuccessful.
Has anyone out there experienced this same problem? Can someone help with troubleshooting and possibly provide solution/FIX.
