Hi all, I have a weird problem that is getting worse, and in googling around I haven't been able to find a clear answer. I have a Denon 3700, an LG B8, and various sources--4k player, Apple TV, Switch, etc. \n\nOne thing that has been happening for a long time: when I turn on the entire system with my Apple TV, sometimes (not always), everything will turn on but the TV will say "no signal." The easiest way to resolve this is to turn on my 4k player. The system would automatically switch to the 4k player, there would be a signal, and then I could just switch the source back to Apple TV and it would show up fine. This is weird and annoying but not so big of a deal that I bothered to try to figure it out. \n\nNow, though, in addition to that, when I watch something on YouTube via Apple TV, essentially every time I click on a video, the signal goes out. And then it is 50\/50 shot as to whether it comes back in a couple seconds or stays out. (Again, if I have the 4k player on, switch to the 4k player, and then switch back, the Apple TV is recognized and the video is playing). Weirdly enough, this also happens every time an individual YouTube video goes to an advertisement or comes back from an advertisement. \n\nI am flummoxed. This doesn't happen (yet) with other apps on my Apple TV (Prime, HBO Max, whatnot). It also does not, as far as I can tell, happen with any other source. I never have a problem with the Nintendo Switch, the 4k player, etc. Although admittedly those are not in use nearly as often. \n\nThe oddest part about this to me is that this new YouTube-specific problem just came out of nowhere, as far as I can tell. \n\nAlso, I have indeed updated the firmware on everything (and turned everyone off and on, etc.). Not sure what else to do, or what the problem might be? I assume it is the Denon that is the issue, since the video is still going (just not getting picked up) but since it only happens with the Apple TV, maybe not? Maybe it is a problem with both? Any suggestions\/ideas would be helpful, many thanks in advance.
