I have had my AVR-889 for about 4-5 years and has been running flawlessly 24/7/365 (almost
). About 1-2 months ago I upgraded TVs from a LNT-4669 to a Panasonic VIERA GT50 (which I am amazed with). My setup was as follows:
Cable/PS3/XBox360 (HDMI) --> AVR-889 (HDMI In) --> AVR-889 (HDMI Out) --> GT50 (HDMI In)
This setup worked for about 2-3 weeks. All of a sudden I received a "No Signal" message using any of the HDMI ports. At first I thought it was a "handshake" issue so I upgraded the firmware on the TV and checked all of the settings on each device (even the crappy menu on the Denon!). To my dismay none of the settings made a difference. I then got out a component cable and was able to run my Motorola Comcast box through the Denon and to the TV which worked.
So, it appeared that, my GT50 had a bad daughter card that needed to be replaced. Warranty tech was unable to remove a few screws that he stripped so the TV was replaced with a new one. I hooked everything up today only to discover that I was still unable to use my HDMI ports! I then brought out my old Samsung and connected that to my Denon, that also did not work with HDMI.
My question is this: Could the HDMI Out port on the Denon shorted, taking out the daughter card in the GT50? Difficult to troubleshoot a definitive answer, does the HDMI port have a signal that I could test to see if it is completely dead?
Thanks very much,
P.S. I also did a factory reset on the Denon which didn't fix anything.
