    hi, my problem with the new appletv 4k is, that i set volumecontrol for the siri remote to: receiver via IR.
    so i can adjust the volume of my av-receiver with the siri remote.

    first problem now is, if i turn of the appletv of, my tv will turn of too.
    second problem is that if i turn the appletv of, the white led is still on.
    it doesnt mather if i turn of my av-receiver before or after the appletv.

    when i set volume control of the remote to of, everything works normal, but thats not how it should be.

    can anyone help?

    ATV4 and 4K support HDMI-CEC which is a standard that allows data to be sent over the HDMI link to control other devices (see link below). If this is enabled, turning ATV on will also turn on any HDMI-CEC devices in the chain, and can adjust volume via signals sent from Siri Remote\ATV using HDMi instead of IR (don't have to point the remote to make adjustments). it is often named something different on some components because of marketing wonks who want to make an industry standard sound like a whiz-bang original feature.

    If you turn this off on all components, you can control them with each of the respective remotes.If you enabled it on all components, waking or sleeping ATV should wake or sleep all components, and possibly control volume directly as opposed to via IR.

    The ATV only turns off when power is unplugged. If you mean putting it to sleep (hold the home button and select Sleep), the white light should go dark. If it is staying on, then the ATV is not sleeping. It may be that one of the components has CEC enabled and is waking the ATV.

    So, go through settings on your TV, Receiver and ATV and set CEC common on all of your devices to remove some of the mystery. Most components manufactured in the last 5 - 10 years or so should support CEC. But, if you are connecting in any way other than HDMI (ie Toslink from TV to Receiver), or if you are using older HDMi cables, CEC won't work. More on CEC here.

    The best way to connect everything is HDMI 1.3 cables, either ATV <> Receiver <> TV, or ATV <> TV <> Receiver (via ARC link). If it is ATV <> TV and then Optical\Coax from TV to AV receiver, HDMI-CEC is off the table. The nice thing is, if you have multiple HDMi inputs to TV or Receiver, turning any device on will start the chain and auto select the input for that device.

    Check your sleep timer and screen saver settings on the ATV as well.

    • If your TV does not support CEC, I'm guessing you have it plugged into an electric jack on your receiver. Thus, you turn off :apple:TV, it turns off the receiver and power is cut off to the TV.
    • If not, do you perhaps have an extension cord plugged into an electric jack in your receiver and the TV is plugged into that?
    • Simple test: ignore :apple:TV. Turn on TV and Receiver. Turn off Receiver. Is TV still on? (unplug the :apple:TV for this test if there are any doubts about it's influence on power to the TV)
    • Simple test #2: ignore the receiver. Turn on TV and :apple:TV. Turn off :apple:TV. Is TV still on?
    • Simple test #2B: same as above but turn on TV with it's own remote. Turn on :apple:TV. Go over very close to the :apple:TV and use your body as a physical barrier between the :apple:TV remote and your TV's IR sensor. Turn off :apple:TV. Is your TV still on?
    Basically, if your TV does not have CEC (do you know this for sure? many TV makers do not call it "CEC" but other names like "Anynet" and similar), it can't be turned off by :apple:TV without an infrared AR signal getting to the TV and/or power being cut off by the receiver (built-in electric jack) possibility (thus CEC between :apple:TV and Receiver).

    • Does it stay on permanently or does it eventually turn off if you just leave everything alone for a while?
    • Simple test: turn everything on so you have an :apple:TV picture on your screen. Turn off only the :apple:TV. Does the TV screen go blank but the white LED stays on? Any sound playing? Any screen saver action start up after the 5 or 15 minutes?
    By "volume control to of" do you mean you are turning the volume all the way down? Else what do you mean?

    test1: yes tv is still on
    test2: both are still on, appletv wont turn of if the receiver isnt turned on (checked it because white led is on and tv, and when i turn on the receiver to get a pciture, i see that the appletv is still asking if i want to go to power safe mode, i said yes when i didnt see the picture multible times)
    test3: no the tv turns off, now the white led is turned off too!!!

    it turns off hours later, i dont know how many hours.

    Describe how things are wired together. I'm assuming it's :apple:TV HDMI OUT to Receiver HDMI in, then Receiver HDMI out to TV HDMI in.

    However, based on your answers, I'm starting to think it's :apple:TV HDMI OUT to TV HDMI in, then maybe TV (something) OUT to RECEIVER (something) IN. If this, what is the (something) connection- optical?

    So in summary:

    Wiring setup is :apple:TV HDMI OUT to Receiver HDMI IN, then Receiver HDMI OUT to TV HDMI IN.

    :apple:TV sleep timer is set to 15 minutes and screen saver is set to 5 minutes.

    You are confident the TV does not have CEC, including CEC by another name like Anynet for Samsung, Viera Link on Panasonic, etc. CEC is turned OFF on the Receiver.

    A. All 3 turned on: Turn :apple:TV off and TV turns off too, whether Receiver is turned off before or after :apple:TV is turned off.

    B. TV + Receiver On: Turn Receiver off, TV stays on (so it's not a TV-to-Receiver power plug turning off the TV, when Receiver is powered down)

    C. TV + :apple:TV on: Receiver off. Try to turn off :apple:TV but it won't turn off unless Receiver is turned on.

    D. TV + :apple:TV on: Position obstacle so that :apple:TV remote can't IR to TV. Turn off :apple:TV but TV turns off anyway. (you sure you are blocking the IR receiver on the TV? Get a box deep enough to completely enclose the remote. Have both ends open. Put one end around your :apple:TV, put remote inside the box from the other end and turn off the :apple:TV. Does the TV turn off too? Basically, what you are trying to do is guarantee that there is NO WAY for the infrared signal to get to the TV IR receiver. If :apple:TV is really close to the TV, temporarily move it so that there is NO WAY for the IR signal to reach the TV.

    E. When using volume control feature with :apple:TV remote, turning off :apple:TV may turn off TV but not :apple:TV. However, when NOT using volume control feature, all works as it should in terms of power on and off.

    F. Turn everything off but :apple:TV LED glows for upwards of hours before it finally turns off.

    The objective is to turn off the :apple:TV but not have it automatically turn off the TV.

    Based on the outcome of the experiment in "D," I'm mystified assuming the summary above is all right. I think your :apple:TV remote is sending an IR signal to turn off the TV when you turn off the :apple:TV.

    HOWEVER, :apple:TV barely sips power and appears to turn itself off after a long period of inactivity. Maybe use :apple:TV to learn your TV remote and then use it to control your :apple:TV (turning the tables on the remote)? I use a universal remote and just put the little :apple:TV remote away. If the LED is too bright or just bugs you, a tiny piece of electrical tape can make it seem permanently off.
