Everything powers on fine, but had to add delays or the input wouldn't change properly, but when I power off the TV stays on. It doesn't matter the order I have them the TV won't power off, I have to go into devices and power off manually. That works just fine. All CEC and ARC settings are off.
I was hoping to get some pointers but it seems I'm not the only one with the issue.

Also in my family room, master bedroom and office, I don't have the same issue.

I've had a near opposite problem with my Apple TV 4K turning the TV off and not letting another activity like Roku use the TV. Maybe you've tried changing device order in power down sequence but what order? If you can follow my reason, I believe there's a logical order. I'm trying it but also some other things I've noted with trial and error. HDMI-CEC is suspect even if disabled and even if blocked on suspect device? Say it ain't so!
Well, despite my TV and devices having HDMI-CEC disabled, my ATV4K seemed a menace with its antics. Sometimes, it wouldn't allow the TV to be turned on? Other times it would turn the TV off before another activity could use it (even changing activities). I'm still undecided about what could cause that because the ATV4K had a HDMI-CECless Lindy adapter on it at the time when it seemingly refused to allow the TV to come out of standby. But rather than eliminate least likely cause, one by one, to narrow suspects, I just cycled power to the ATV4K and immediately was able to turn the TV by starting at activity.
But what didn't make sense was that the Logitech Harmony 950 connected to Harmony hub wasn't even starting an activity. I'd press activity start on 950 display window and nothing happened; no errors either! I tried to duplicate this by rebooting the Harmony hub while trying to select an activity start with the Harmony 950. But rather than nothing on the 950, it says something like something is wrong, check connection.
I sent my logs to Logitech Harmony and sent an email asking them to investigate a few oddities that I had time stamps on. Got a response saying they needed to have a technical support call with me to manually update my Harmony 950 and Harmony hub to latest update. Apparently, they weren't successfully reaching servers for updates, despite my Android app popping up a dialogue that said checking and downloading firmware. Got that sorted too.
But what I wanted to share was what I found in the start and end sequences of my activities. TV should power out of standby first, IMO. Check. Ok there. But TV should be powered to standby last, IMO. Not the case; TV was first? This didn't seem logical. I changed my TV to last device in end sequences (when no longer needed is also selected).
The reason? I noticed my ATV4K was reluctant to go to standby unless TV was on and input was tuned to the ATV4K. Sometimes I would find the ATV4K not in standby. The day the TV wouldn't turn on when starting an activity, I asked the Harmony 950 for help to resolve the matter. What the 950 expected was all devices off; it hadn't started an activity? Odd! So I'm checking all the devices looking for what's still on as I go through the help sequence. Sure enough, found the ATV4K wasn't in standby. As I said, it's reluctant to take a standby command without TV on and tuned to its HDMI port, even with Harmony sending repeated commands. That's when I cycled AC power to the ATV4K and managed to start an activity successfully. (Theory? ATV4K has hijacked my TV; maybe even trying to turn it off before it goes to standby? And this despite HDMI-CEC being blocked.)
A lot to say to come to the conclusion that the TV should be last in the standby order and only "off" (standby) when no longer needed. And first to come out of standby in any start sequence.
I have no idea if that effects users with an AVR or not?
Suggestions, tips or experiences? I've also discovered it's best to not actually remove AC power from my HDMI devices connected to my TV. Causes more of the negative things I've described and more. Another thing I'm having to do overcome some of these nuisances is to remove power and cabling from my TV and connected devices, hold TV power on button until LED can no longer emit and wait before cabling and restoring any power. Lying disconnected and without power allows any residual charges to dissipate before cabling and powering on. I'm also considering a factory reset on my TV.
I suspect disabling CEC in TV and devices and even blocking the ATV4K CEC isn't enough. HDMI is suspect in some way though I've also read HDMI-CEC can work nicely until adding multiple capable devices. Then it can be a game of chance; sometimes this works without issue, others, may not be so good. I've got 3 HDMI CEC capable devices and it seems to be a nightmare for my TV.
Harmony is supposed to be a helpful solution. Maybe it is when used the right way. Hopefully I'm on the right track now. Just sharing my trial and error findings. Ask Harmony and they'll say the firmware updates were critical in my case; must update. I still suspect foul play with what continues...
I may also have an opportunity to just try one device if cancelling satellite paid TV. Despite my lessons and applied suggestions, Tennis TV app on Roku and ATV4K are acting weird. Roku tends to lockup and reboot going from watching replays via menu date and tournament, exiting and tabbing left to live content (regardless if live content is available or not but this doesn't always happen, just most of the time lately- tab right before before tabbing left to live tab and this doesn't happen- why? Don't know). ATV4K has a weird issue with Harmony right directional arrow in same Tennis TV app's replay tab. First right tab in the same date and tournament menu of replay tab and the app will exit every time to ATV4K home (app menu). But only if using Harmony hub to tab right at that critical tab right to select a date in replay tab menu. Use the ATV4K Siri remote to swipe right at that one step, no exit to home! I can then use Harmony without ceasing to keep tabbing left and right even at that point without exiting app to home. And I've seen these issues temporarily fixed by doing the power down recabling procedure on TV and devices above. So I'm curious to see how my TV and streamer behaves with only one HDMI device connected. Do these issues disappear and never return or eventually come back again?
Strange but true and mostly unknowns because there's no perfect streaming device and I'm in no hurry to experiment with such a setup until I'm ready to go at it with just one connected device. It's better than before if can just recall my per device remote workarounds for Tennis TV app.
