Alright, i had two broken barco data600, i changed/swapped boards and cards until i had one pj running. If to say, i connected a RCVDS to the projector and a video to the RCVDS. On the convergence board i put the switch onto 'intern crosshatch pattern' and i get the crosshatched projection which i had to focus and adjust on. No, after setting al well, it's time to give that switch a push to get it in videomode. I push start on my videomachine and I switch pj from 'intern crosshatch pattern' to 'video' on convergence board but: no projection! The tubes don't give light nor projection! I switch back onto the ''intern crosshatch pattern' and the crosshatch is being projected! what am i doing wrong? any help from you? thanks!
