I have recently been given a Beckhoff Model CP6003-1002 Industrial 18" LCD monitor that is in non-working condition. I believe that this unit was actually manufactured by TopVision as that's whose name is on the controller boards inside the unit. It appears to have a power supply problem that I can't get sorted out. The unit is completely dead. No power - no indication of power. Checked for AC in and all is well up to the rectifier. I'm wondering if anybody knows of a schematic that is available for this machine. Any help appreciated.
Also - the AC voltage in to the rectifier is around 120V AC. The voltage out of the rectifier is around 165V DC. Does this sound right?
