Question about HDMI-CEC to a Panasonic TV

My TV (Panasonic TH-85X840Z) has a setting whether to recognise TV-on and TV-off from the external input.

If I am watching some other input, and turn the TV off, it will switch correctly (on and change inputs) when I press a button on the aTV remote. But, if I was previously watching the aTV and put the TV on standby, the aTV remote won't wake up the TV again! i.e. this only works if I *wasn't* watching aTV when I switched the TV off.

That's a bit annoying. Anyone know of a solution to this?

I have a panasonic viera. Make sure your vieralink stuff is all enabled. I think I turned off any 'sleep' option of the TV and let the ATV sleep do it.

Ill check this evening to see if I can force sleep of the tv and then work with the atv remote.

That'd be great, thanks. It all works swimmingly except for the one case when I turn off the TV while it's on the aTV input. If I was watching something else before I turned it off it works correctly.

I don't have any sleep options on.

Interestingly, if I turn on HDMI power-off (on the TV), and then use the sleep from the aTV this powers off the TV. And then it'll turn it back on again. But still not if I've used the TV's remote to turn the TV off. Weird.

I also have a Viera with CEC and it's pretty great. Turning on the Apple TV with the Siri remote turns on the TV and puts it on the proper input. Putting the Apple TV to sleep with the remote turns the TV off as well. If I switch over to another input and the Apple TV goes to sleep from inactivity, the TV remains on. Very handy feature for me so far.

Edit: Totally missed your question. I'll see if I get similar results when I get home. I don't think I've ever put the TV on standby before, only on/off, so I'm not sure if there's a solution.

I put my tv to sleep and it turned the atv off lol. If I turn off my TV while watching the apple and then do something like press the apple tv play/pause button, the atv turns the tv back on ok.

Here are my vieralink options:
power on link: yes
power off link: yes
Energy savings: quick start
unselected device energy: stay on
default speakers: theater

Eco/energy:
No activity for 3 hours: stay on


edit Im using the latest tvos beta

I encountered a bug last night. I put my Apple TV to sleep using the Siri remote, and the TV turned off like normal. 90 seconds later both turned back on without input from me. Turned it off in the same fashion, got the same results. I had to turn the TV off manually like a caveman to get the system to stay off. Hoping for an update to fix this soon.

I'm having the same issues with my Sharp LED and Onkyo receiver. When I put the ATV to sleep with the remote, everything turns off just fine. Then a few seconds later, everything turns back on again by itself. I can't figure it out. I turned CEC off until I do.
