TX NR709 Main HDMI out doesn't work, Sub works

Had my TX NR709 for 3 months now and was working great, but today the Main HDMI out stopped working. No signal at my projector. When I switch my HDMI cable to the Sub Out connection, it works fine.

I tried all of the Output selection choices: Main, Sub, Both, and on all, the Main has no signal, and the Sub works.

I tried the input in the dvd/bd and the vcr connections but same results as above.

Any other test or insights would be appreciated.

Thanks in advance.

Hi mith,
I am going to ask you to try a reset:
To do the reset you need to turn the receiver on, then on the front panel of the receiver press and hold the "VCR/DVR" button while doing that press the "STANDBY/ON" button. You will see the word "Clear" in the display screen and the receiver will go into standby mode. PLEASE UNDERSTAND THAT YOU WILL LOSE ALL YOUR AUDIO & VIDEO ASSIGNMENTS ON THE RECEIVER PLUS YOU WILL LOSE ALL YOUR SPEAKER CONFIGURATIONS, SPEAKER DISTANCE AND ALL LEVEL CALIBRATION SETTINGS. YOU WILL ALSO LOSE ANY PROGRAMMED RADIO STATIONS IN MEMORY. Once the receiver goes into standby mode turn it back on and go thru the setup menu for all custom settings.
Please keep us posted and thank you for contacting Product Support via our forum.
