TV on/off sync issue

[Squishman]

My theory about turning cec off then back on on the fs may have solved it doesn't explain why the tv remote power button was ineffective.

HDMI-CEC can be a very ugly thing. With many TVs, it is only fully functional when connected to the ARC/eARC port. The receiver can also lose its mind at times and will need HDMI Control turned OFF and back ON to refresh the list of connected devices. Onkyos will display the list of devices on the front panel when doing so.

This might be fixed by hot-swapping the HDMI cables, too. Stranger things could happen.

NOTE- some manufacturers advise against changing connections when the equipment is powered, so its best to contact each brands' Tech Support department before doing this.

Not familiar with the term .

Hot swap means 'Unplug and reconnect while the equipment is powered'.

It can help, some manufacturers advise that it shouldn't be done, ever, while some say it can be done- I would contact the tech support department for FireStick, Onkyo and the TV manufacturer before doing this.

HDMI requires an 'electronic handshake' in order to work- lots of issues can be caused by this not working as it should. If the signal from one is delayed or another piece in the line of equipment isn't ready, things won't work.

Well, I came home from work and powered it on and everything still works fine. Thx for the help! Seems the issue might be solved.

I don't have a FireStick, but I use Harmony- not sure why the FS would be confused since there's no two-way communication between it and the equipmnent. I can understand seeing problems if a command from one remote is still being sent when a command from the other remote is being received- some equipment acts like it's blond or stunned when conflicting commands come in.

Battery life is one thing that makes a difference- I have a Harmony Companion that uses a 2032 disc battery and when that is starting to go, the hub won't always respond to the remote, so I test it by using the phone app- if it works immedately and every time, I replace the battery but sometimes, neither works and I just have to wait.

Not sure of the reasons. If I use one to start and another to end, it does generally have an effect. I don't use the phone app much, easier to use the remote. I suspect its somewhere along the lines of the Harmony "toggle" command.

This morning, the avr and tv powered up with the fs, then down together. So it's working the way it should now. I think when @lovinthehd mentioned where cec was on the fs, I turned it off, then back on again. That must've been what fixed it.

Just keep an eye on it and any use of alternate remote or setup....
