just got my unit a week ago
all was fine
now i dont get the menu on screen
and hdmi inputs dont show as well
looks like the main monitor out is dead...
any help please?
Try a Processor RESET..
Note that this will erase any station presets, EQ settings but will kleer out any corrupted memory..
Juts my $0.05... 👍😉
I tried it but still nothing
The hdmi sources are fine when connected directly to TV
Since the unit is only a week old, take it back and get it exchanged..
Since Denon shifted their higher end AVRs to China production, these strange type of failures have increased significantly...
Just my $0.05.... 👍😉
The 4520CI is mfr'd in Japan. Try a few resets in a row.
I feel for you I am in a fight with denon over an intermittent problem with my 4520 ci
try soft reset power off and unplug for 10 minutes
also try wiggling the cat 5 port at the back of the amp
I believe the amp suffers from major dry joints in electronic
