Hi, Could someone please help me with a schematic or service manual for Polycom PVS-16XX video conferencing station. The unit powers up and begins to perform its reset procedure with the camera head moving left, then comes to dead centre (horizontal and elevation) and then goes limp as soon as the polycom logo appears on screen( tv connected to video out). I supected the strip connectors feeding the camera moving section and replaced both to no avail. On the board just above the CCD i see a AN8049 which is a 1.8-volt
3-channel step-up, step-down, and polarity inverting DC-DC converter control IC. No CCD image is available and neither is remote traverse and elevation control. Pcbs are real tiny and tracing without a schematic is driving me loco. Any clues? help! Jango- posted
