I have a Sony VPH-D50Q CRT front projector with the built in line doubler board (EXB-DS10) and I recently upgrade my DVD player to a Denon DVD-2900 with progessive scan output. The problem is I can't get the projector to see the PS output. I turned off the board (on the setup menu) and tried various input configs ie: changing input from COMPONENT to HDTV Y Pb Pr but no luck. The projector sees the interlaced signal from the Denon no problem but as soon as I switch over to progressive output the projector menu says "no signal detected" Since the board is fairly old technology, I'd be interested in seeing the difference between it's quality and the PS output of the Denon. Anyone know a fix for this?
