Proxima Ovation SX A812C LCD Projection Panel from the top.

Close up of the control panel.

5-Pin DIN Power connector and RS232 25-Pin Computer connector.  The power plug is the same size as an AT Keyboard plug.

NOTE: The original Power Supply model number is UP30432.

The Ovation 812 can powered by a normal AT Power Supply. I modified mine by removing the extra cables and installing the switch on the inside.

On the inside of the power supply, I soldered the power cable wires to the existing wires and covered the joints with shrink wrap tubing. A few wire ties hold the cable away from the other components and fasten it to the case.

For mounting the switch inside the power supply I removed the monitor jack and made a switch plate out of acrylic plastic. Since the plastic is clear it's easy to mark the holes.

To make the plate:

  • Solder the switch to the wires.
  • Cut Clear Plastic to cover empty hole and screw holes.
  • Hold switch in place and mark location for large hole.
  • Drill 1/2" hole.
  • Place switch in hole and mark two small holes on switch.
  • Drill 1/8" holes.
  • Attach switch to plate with 1 screw.
  • Hold switch in place and mark last two holes.
  • Unscrew switch and drill last two holes in plate.
  • Counter sink 1/8" holes for screw heads.
  • Attach Switch to plate and attach plate to Power Supply.

NOTE: I was informed this also works for the Ovation 846.
