HV board

The below picture shows the HV board. There are no user adjustments on this board, DO NOT turn the trimpots! This board suffers from poor solder joints and the occasional part failure. This board does not have an LED on it to show proper operation, but the lack of picture can be traced to no HV coming from this board. The thick red HV wire goes to the HV splitter. This board fails on a regular basis, and I doa number of board component upgrades to make it more reliable.

Horizontal board

This board contains the horizontal deflection circuits, and will cause a ‘no picture’ condition if it fails. The repairs are usually straightforward, and this board contains no adjustments. To flip the image horizontally for the projector , unplug the three red/blue yoke wires and flip them around 180 degrees, then plug them back in.
