You may also want to confirm whether the firmware was updated. Refer to the post below ... about 1/2 way down is the procedure to determine the firmware version.http://www.avsforum.com/avs-vb/showt...6#post17512496
Thank you for the clarification jdsmoothie.
Here is an update.
I called Denon Support and I explained the situation.
He had me do 2 procedures.
First he had me turn off the On-screen display in the Menu and power off the receiver and wait 1 minute and then power it on and turn the On-screen display settinng back on. He asked if that solved the problem...it didn't.
Then he had me reset the microprocessor and try again. It still did not work and he was actually quite surprised. He recommended that I bring it back to the Service Shop and had them reflash the firmware. I told him, frankly, that since it was just an annoyance that I would probably not. He understood but said that he was not comfortable with me having a receiver that did not work 100%. I found that very refreshing. He was very friendly and professional.
I then called the Service Shop and explained the problem. Their particular problem is that they don't keep good notes, both on the input side and the output side. Although I did mention the on-screen HDMI problem, they only wrote down the HDMI audio/video problems. They also neglected to note whether the firmware was upgraded or not even though 2 weeks after I brought it in when I phoned to get a status report, the technician said he had just flashed the firmware. I gently recommended that they keep better notes.
By the way, the firmware checking procedure detailed in the link doesn't work - I tried it 3 times.
