No Video output Denon X6400H
I originally posted this in the LG thread, but I'm still unsure if it is an AVR or TV issue.
I am having trouble getting my (just delivered) LG OLED 55C9 to cooperate with my Denon X6400H (or visa-versa).
This started the other day when I came home from work and the TV would not power on. I decided to replace rather than attempt a repair on a 12 yr old TV.
The Denon has been in place since Late 2017, formally connected to a Pioneer 5070 Plasma. All sources go into the Denon, HDMI from Output 1 of the Denon to the TV. I made no changes to the Denon when I connected the LG.
The LG will not display Video from the Denon, it WILL output Audio. The LG recognizes that a cable is plugged into the port, but displays "No Signal". If I go directly from a source (blu-ray or cable box) I get Audio & Video. I have the same results using HDMI 1 or 2 on the LG and Zone 1 and 2 output on the Denon. LG support (chat) had nothing for me, since I get A/V going direct from source.
I suspected an outdated or faulty HDMI cable so I ran to Best Buy and picked up a rocketfish "4K ULTRA HD & HDR compatible" cable. No change. My last try was to perform a Factory Reset of the Denon - no change.
I'm beginning to fear that the Denon has failed at the same time as the old TV? It seems my next step is to bring the bedroom tv out and see how the Denon gets along with that. That will need to wait, it is wall mounted and all wires are neatly tucked away with numerous zip-ties, not up for tearing that all apart just now.
Am I missing another possibility here?
