Hi, I've had a UHD51A for a few years now. Suddenly it no longer turns on all the way. Is this the way this machine indicates it needs a new lamp?
I've had challenges with HDMI handshaking issues from my Denon AVR-X3600H for a while now as well, so I am debating how to proceed from here. Perhaps I should get a new PJ.
Regarding handshake issue: The PJ works great when I used to bypass the receiver with the Xbox One X, but after I upgraded to Xbox Series X, I cannot split the audio and video at the source, and when I run the HDMI signal through the receiver, handshake issues occur and the PJ resets itself. It's a frustrating movie interruption, but doesn't happen during video game mode. That issue is certainly one originating from the DENON. I have been unable to solve a workaround. I even tried one of the handshake products that sits in between the receiver and the project, but that didn't work, either (Atlona AT-ETU-SYNC).
So, if this is the way the UHD51A notifies users that it needs a new lamp, I may buy a new lamp, but if this some other projector fault, I may look for a new pj that doesn't have handshake issues with the Denon.
Thanks!
