Same issue with a brand-new M43-C1. Vizio Support was not helpful. I hate that I'm bothered by this, but it's really hard to get to sleep when that thing is glowing. Guess I'll be taking it back.

My setup consists of ATV4 plugged into my Yamaha receiver which is then plugged into the LG tv.

Powering on and off works for the LG TV AND ATV4. But NOT the receiver. I have to manually turn on the receiver and turn it off manually after watching ATV...

Edit:

After changing a few things on my receiver I can turn on and turn off the TV, ATV4 and receiver using the Apple TV4 remote. I did this by changing the hdmi control on my receiver.

Hope this helps someone.

CEC sucks - always has.

Even a fully working CEC setup invariably flakes out at some point and leaves you digging for the remote of some component.
 
Works great for me on my Panasonic plasma, but I had to go into the TV settings and turn Viera Link on.

Turning the aTV on also turns the TV on and switches it to the aTV input. When aTV enters sleep, the TV is turned off if it's on the aTV input. Otherwise, it stays on on.

i have almost the same setup - apple tv into marantz receiver into lg tv (lg65ef9500) i can turn everything on fine but when turning it off the Lg goes into a "sort of " sleep mode - it doesn't fully turn off. how do you have your lg set up? - there doesn't seem to be too many settings for HDMI on it.
 
In the same boat.
I also have an LG TV. However, the Apple TV does turn it off most of the time. Unfortunately it's not a given! The first five days it had been working just fine. It started happening a couple of days ago. I can't find anything in the TV settings that would make it automatically shut off when there is no signal. Ridiculous!
i was on the phone with LG support for an hour - they were useless. one guy said the tv doesn't have an auto shutoff feature if it doesn't receive a signal. I don't think LG has the HDMI CEC functionality of the new tv fully backed.
 
check the settings on your TV. Some manufacturers call CEC something different:

  • AOC: E-link
  • Hitachi: HDMI-CEC
  • LG: SimpLink
  • Mitsubishi: NetCommand for HDMI
  • Onkyo: RIHD
  • Panasonic: HDAVI Control, EZ-Sync, or VIERA Link
  • Philips: EasyLink
  • Pioneer: Kuro Link
  • Runco International: RuncoLink
  • Samsung: Anynet+
  • Sharp: Aquos Link
  • Sony: BRAVIA Sync
  • Toshiba: CE-Link or Regza Link
  • Vizio: CEC

I have an 8-year-old Panasonic Plasma, and you can change the settings in the TV's setup menu for whether you want external devices to turn the TV on or off. You can enable or disable either one. I believe the feature is called EZ Sync on this model. It's called Viera Link on my newer Panasonic.

I have a similar-aged Panny plasma (2009 I think). It has Viera Link settings like you mentioned. When I plug my ATV4 directly into the TV, it powers it on and off accordingly (after fiddling with the settings), but my Harman Kardon AVR is oblivious to any of that. Kind of made sense when I thought it through though. So I plugged my ATV4 directly into the AVR, then monitor out to the TV. Now everything turns on when I wake up the ATV4, BUT nothing turns off when I put the ATV4 to sleep. That's frustrating. If the remote could do a IR-based power off command to the TV, then the AVR would turn off accordingly, but I don't see a way to set that up with the Siri remote.

Anyone tried having all content sources plugged into TV inputs and then running an HDMI ARC to the Receiver?

CEC is a headache, but I've usually found my best results with something like I described. I have too much stuff anyhow and use a Harmony setup, but just a thought at least.

I think those settings on the TV are for allowing the TV to turn other devices on or off, not the other way around, because they don't have any effect on the Apple TV turning off the TV when it's put to sleep. I had to disable the setting on the Apple TV itself to stop this from happening.

I avoided CEC with past setups because it was inconsistent, but with the aTV4 I wanted to give it a go again. I have my aTV connected to my audio receiver via HDMI, which outputs to the TV. The TV sees the aTV and the receiver as CEC-enabled devices.

When I first put the aTV to sleep, it shut everything down. Then everything came back on again. Something was triggering it all to power back on. I turned the TV off manually, which powered everything down (and stayed down), and assumed I'd just have to turn it all back off later.

Since then, I haven't had any issues with it at all. I have had 1 situation since then where I told the aTV to sleep while it was in the middle of playing a NetFlix video, and I think that the app was keeping the aTV from actually going to sleep in time - triggering the TV and receiver to power back on. Other than that, everything has been properly synchronized.

I've also used the TV and receiver for other purposes besides the aTV for several hours, and have not had any issues with the aTV going to sleep on its own & triggering shut-down.

There's no compelling reason to force the aTV to go into sleep mode if I'm still using other components. Its power consumption is minimal and it's set to go to sleep after 30m of inactivity anyway. When putting it to sleep deliberately, the warning message specifically states that doing so will power down other CEC connected devices. So it's not a surprise if that's exactly what it does.

As a bonus, whenever I change my TV input to antenna now, my receiver automatically switches to the proper audio setting (and back when I change it again.) That's pretty great.
 
In my Apple TV remote and devices setting

"Turn on your tv with your remote " doesn't turn on when I click on it

I am using a hdmi switch , could that be the reason ?
The Siri remote was able to control my tv volume automatically

Yes, the switches usually are not CEC compatible. Volume controls are done over IR.
 
I have a Philips TV and had the same issue (Sleep Mode turns of TV but waking doesn't turn the TV on). For me the solution was to connect my Apple TV to HDMI1 specifically. Don't know if it's a thing that's specific to my model but maybe this will help... so try other HDMI ports :)
 
I have similar issues caused by HDMI CEC. In my case, turning off everything using my universal remote causes everything to go off and then some devices to selectively turn back on (e.g. TV or amp). It's very frustrating.
 
On my Sony Bravia, it powers on the TV when turning AppleTV on, and powers it off when I put it to sleep. It works well, and I like it.

Works perfectly with my 2006 Bravia and Onkyo reciever as well. I love it as I no longer need a universal remote.
 
For my situation--ATV, Samsung LCD, Denon receiver--everything powers up and turns off properly when I wake/sleep the ATV, the only problem is that the receiver immediately pops back on again. I can only speculate that it's somehow getting the signal twice, prompting it to turn back on again.

The other annoyance is that the TV volume is disabled as sound is played through the receiver, but adjusting the volume on the ATV remote makes the TV volume level display on the monitor right on top of the receiver volume level, rendering it unreadable and looking bad. Unfortunately, there appears to be no way to disable the volume display on the samsung monitor.

I have the opposite problem with my Sony in that I never want Apple TV to power my Sony on or off.

We have the TV running all day, large family, and it's always on FiOS for watching broadcast TV. We use Apple TV situationally, turn it on for an hour to watch a show, then go right back to FiOS for broadcast TV. So it's completely annoying to be watching broadcast, flip over to Apple TV for a bit, then flip it back to broadcast and have Apple TV shut off the Sony. It's not the experience we want at all.

I do not have a problem, mine works. it's great.
(posting for the sake of saying the feature works as intended)

That depends on your use-case.

If you want your HDTV and Apple TV to power on and power off together then the feature works as intended for you.

But for many of us, we leave our HDTV's on all day and merely want HDMI-CEC to switch inputs and not turn the power on or off at all. When I turn my Sony Bluray on/off it doesn't turn the power on/off to my Sony HDTV, it just changes the input from Cable to Bluray while watching and then changes it back from Bluray to Cable when I shut the Bluray player off. That's the behavior I'd expect from Apple TV. It doesn't give me that option.
