My Z2 has pretty much been doing this since I got it new and I've kind of lived with it, now however, it's really annoying me. If I power up the projector, and then switch on the DVD player, the Z2 won't find a signal. Switch on the DVD first, then the projector, everything works. If I switch off the projector half way through a film, but leave the DVD on, the projector won't find a signal when I switch it on to finish watching. It's not a problem with the DVD player, as I've tried a Tosh 330 and a Pioneer 370, and I get the same result. For cabling, I run a S-Video cable from the DVD to a Denon 1803. From there is goes onto the Z2. The Z2 also has composite and DVI cables hooked in the back for additional sources. I don't think it's the Denon at fault either. Odds are it's now out of warranty, but it's possible that a firmware flash will fix it (it's still running the original firmware from release). Is this something I can easily have a go at?
