THE FAULT IS DUE TO TWO OR MORE OF THE PANEL BULBS OPEN CIRCUIT ON THE REMOVABLE CONTROL (FLIP-OFF) PANEL. WITH THESE BULBS OPEN CIRCUIT THE INTERNAL LOGIC THINKS THAT THE FRONT PANEL HAS BEEN REMOVED, AND IT WILL NOT ALLOW THE UNIT TO BE SWITCHED ON.
CAN BE REPLACED WITH CARE (Soldering required)
REPLACEMENT BULBS - 6volt "Grain of wheat" type -
