I have a NAD M15HD which I am having big trouble regarding HDMI-output. I have already replaced one unit because this trouble.
The first M15HD-unit had some problems the first time I tried it. What happened was that the projector couldnt find any HDMI-signal. I switched it on and of, pushed the reset buttons back to factory default etc. Then everything worked as it should for some days, but the next time suddenly the projector said "No HDMI-signal" again. This continued until I got tired and complained to my local dealer.
My local dealer replaced this unit and I got a new one which seemed to be all right in the beginning.
But this weekend the new unit appeared to have the same problem as the first one. The new M15HD had worked just fine for several weeks, but suddenly I just got the message "No HDMI-signal" and what ever I did nothing changed this. This happened when I powered on the M15HD after standby for a couple of days.
The problem is that my projector, Epson TW2000, says "No HDMI-signal" and I cant get the M15HD to "connect" and show the menu or anything else.
This happens no matter which source I choose. It doesnt matter if I choose my Denon 2500BT bluray, Xbox 360 or my computer.
The M15HD is connected to the Epson projector with a 15 meter long QED hdmi-cable of decent quality. This setup has worked without any trouble when I had a Denon 4308, 2310 and 3310. I have also tried to use another hdmi-cable brand without any difference.
My dealer says that there is nothing wrong with my new M15HD, nor was it anything wrong with my first one, and suggests that there must be something between my Epson projector and M15HD.
I have tried to eliminate every possible source for this problem, but it all boils down to the M15HD.
As far as I am concerned the OSD-meny should occour on the screen independent of which source I choose, but this is impossible when I get this HDMI-message.
I have checked all connections, pulled them out and back again. I have tried different sources, cables etc. I have switched everything completely off, and then turned everything back again in different order, but nothing seems to help.
Yesterday I tried a Denon 2310 reciever and connected it exactly the same way as M15HD, and everything worked just fine. No HDMI-issues.
Could this be a handshake problem, or low hdmi signal strenght output from the M15HD? Maybe a HDMI-booster would help? If so the signal output is weaker or different from the Denon-recievers I have tried without any trouble.
