I picked up a Barcodata PC Analog-chassis CRT projector. It's similar to the 600 series, but older. When I hook it up to the RCVDS all three CRTs display a nice white screen. The red may be a little weak, but I might be able to tweak that. However, when I flip the switch to view the test pattern, the screen gets all wavy and destabilized like it is unable to sync properly. Any input into the RCVDS has the same result. Any idea what needs to be fixed? Convergence board appears to be working properly... what else could it be? Charles.
