Sorry for the long post, but this is driving my crazy --
Here is my setup - Denon 3910 video signal output via DVI to a Pioneer PRO1410 (61" Plasma) HDMI input via Gefen HDTV Cat5 repeaters. Setup has worked flawlessly for nine months until two weeks ago.
Here is my problem - Watched a movie with kids and the system functioned perfectly as normal, shut down the system, attempted to watch a second movie forty-five minutes later and the video signal would not hold steady. Picture changes from perfect image to grey "no signal" screen continuously. Consistent tempo of about half a second of picture followed by half a second of grey "no signal" which repeats regardless of whether a DVD is loaded in the player or not. The actual "no signal" verbiage does not appear, but it's the same screen as when there is no signal.
What has been done -
Second 3910 player results in identical video issue when connected to my Pioneer Plasma.
An LCD plasma connected to my 3910 results in perfect picture when connected directly to the DVD player or at the other end of the Gefen extenders.
My 3910 connected to second Pioneer Plasma 1410 TV at reseller's facility results in same rythmic flicker, but not an actual full grey screen.
Pioneer plasma service technician connected Samsung DVD player via HDMI and the picture is perfect connected directly or via the Gefen devices.
Gefen devices have been replaced and symptons or issues have not changed.
Second 3910 player has not been connected to second Pioneer TV, so I don't have those results.
Finger Pointing - Pioneer technician says it's the DVD player, because Samsung works great. Home Theater installer says it's the TV, because LCD TV works perfectly and second 3910 has same symptons. TV reseller says it's the DVD player because of the flicker when my 3910 is connected to a second Pioneer Plasma.
Next Steps - I'm going to take the Denon 3910 in for repair, but was wondering if anyone had any advice. This is a very strange problem as testing with duplicate gear has resulted in more confusion instead of clarification.
