So i have tried on 2 TVs now and am really frustrated right now. Amazon claims that the fire goes into sleep mode after 30 minutes and i guess this is true it never said that it does this but it does not turn the TV off it just keeps the output alive with a black screen. i find this crazy my laptop can go to sleep mode which turns off the monitor or TV it is hooked to. i tend to fall asleep to TV and movies. so my screen running all night long disappoints me i would assume that sleep mode works like that shutting off my TV or at least killing the output on the HDMI so the TV will detect no source and auto shutoff.maybe I'm missing something but is there a way to do what i want, after some amount of time have the device either over CEC or by killing the output, turn off the TV when it goes into sleep mode or a similar? I have not rooted my AFTV but am willing to if that is what it takes. I managed to root the MotoX so i can root anything i feel like.

I see two possibilities, both would be kernel modifications and both would require the kernel to know if it's "sleeping". Either turn off the HDMI or send a CEC command. CEC is pretty flaky, so I would probably go with turning off the HDMI. I don't know about your TV, but my TV will sit on the "no input video" all day long, so that doesn't really solve your problem. But regardless, the HDMI driver is pretty big and finding the right spot, and trying to figure out when it's sleeping... I don't really see it happening. Plus, no custom kernels can be loaded until the bootloader unlock is released.

i feel if CEC works i can set a timer or something in llama or something for idle time i just dont know how to control CEC as of now i find that black screen so freaking frustrating. it is part of the reason i went with the AFTV over the roku. any idea how to play with the CEC? and my TV does auto shut off it no source is attached. if only i could get netflix remote friendly on the PC i would just use a regular HTPC.

I use the built in feature of my (Sony TV) SLEEP. works great.
besides... if your FTV goes to sleep, and in effect BLACKS out the screen, your TV is drawing almost if not the same power as if it was in it's OFF or standby mode anyway. The LCD/LED of the TV draws/consumes more than 90% of it's power. I'm guessing if you put one of those 'kill-a-watt' meters on your TV you wouldn't see a difference between turning it off with the TV remote, and when the TV monitor has a BLACK screen.
If your TV is plugged in, it's drawing power. All TVs need to have skeleton circuits energized, so it can respond to IR remote power ON commands, as well as scanning the push buttons or capacitive touch buttons ...
I use a Master/Switched outlet powerstrip on my TV, to turn off an audio amplifier for my bookshelf speakers - when the TV is switched off. This works great. I noticed that when my FTV goes to sleep, the screen goes BLACK, shortly after that (seconds) my amplifier goes off. This indicates that the threshold setting of my powerstrip, 'thinks my TV has been turned off, hence shutting of my amplifier.(enven though my TV is really still ON, if I switch input to my TiVo the screen comes back with a video signal & my amplifier turns back on.
On a side note... I also noticed that it (FTV) doesn't seem to go to SLEEP if I leave it running XBMC -- not positive about this, but for sure one day I left XBMC home screen up, and switched my TV input to my TiVo ... and hours later my FTV power lite was still on. So if you were watching a movie with XBMC and fell asleep, it wouldn't matter - it would have stayed on anyway. I try and explore that more -- but when exactly does the FTV go to sleep? no remote commands for 30 mins? What determines inactivity? I've never had mine go to sleep while watching a movie... (no remote input/outputs for more than 30 mins)
So when the TV is ON/OFF and or asleep .. or just has a BLACK screen. Those are all relative terms, for Ha Hahs ... get one of those "Kill-a-Watt" meters and compare. I have a friend that has one - if I remember I'll ask to borrow it to confirm my theory.

Interesting find on the power consumption of your TV while it is black I was also thinking of maybe using an RPI to do the XEC stuff while the AFTV must sends it a network command to turn the TV off when it goes into black screen with llama. I might go buy one of those kill-owatt meters today.

Well.. I was wrong. I thought there would be less difference between standby,ON with video , and BLACK screen but still ON..
standby (16.0 watts),ON with video(221.3 watts) , and BLACK screen but still ON (58.3 watts)..
Our TV (an older Panasonic) has a sleep setting that turns off the TV after X time of no activity - if the only input is over HDMI, the set shuts down after that timeout.
It's annoying that it doesn't see HDMI as activity, but it means the set actually does power down once it's been idle long enough. I'd love to have more flexibility in setting the timeout - I think we only have disabled, 30 minutes and 3 hours as the available options - but I've left the setting as it is for a long time now and am used to it.
I'm using the firetv with a projector and have the same problem as all of you. The 'Auto Off' Function of the projector does not work because the hdmi port of the firetv is seen as active by the projector. This is pretty annoying since I fall asleep on the couch sometimes and lamp hours on the projector are precious.
Now my raspberry pi has a command to power off HDMI through '/opt/vc/bin/tvservice -o'
I wonder if something similar can be achieved on the firetv. .. I hope that rbox is working on a custom kernel now that the bootloader is partially unlocked!
I did a search thru the HDMI-CEC specs and not once did I find any mention that it had a command to turn of the TV.
My fire TV never seems to go to sleep in general, the light is always on and it's frustrating I've tried what I could considering I'm not rooted due to the new upgrade. I wish I would have rooted it back when I bought it but I never got around to it.
Sorry for digging up such an old post but I have the same problem and would like to know if somebody fixed it.
I'm using a Fujitsu PC monitor and a FireTV Stick to stream some Netflix before going to bed. Turning off my PC immediately triggers the monitors standby because the signal is gone, but sending the FTV to sleep seems to keep the HDMI active, so the monitor just shows a black screen, but stays active.
Is there any way to turn off the HDMI completely?

You can switch off all CEC devices via broadcast or a single device via address (address 0 is for TV).
CEC 13.3 System Standby
CEC 13.3.1 Messages
The following message is used for the System Standby feature:
<Standby>
CEC 13.3.2 Feature Description
The broadcast message <Standby> can be used to switch all CEC devices to standby.
...
A device can switch another single device into standby by sending the message <Standby> as a directly
addressed message to it.

This is completely a bug in the device. I use it for plex and I'm buying something else from this point forward.
This is NOT, I repeat NOT a command (HDMI-CEC command). All the device should be doing is what a computer/blu-ray player/anything else does and turn off the display to the port entirely after X minutes. This allows your TV (or in my case my projector with it's $450 light bulb) to detect that there is no signal going to it after 10 minutes and turn itself off.
This also causes COUNTLESS other problems in a home theater setup. It won't let your receiver auto off, which won't let your projector auto off, which won't let your associated devices auto off (sub, speakers, whatever).
Every other device I have works perfectly fine in this manner. A computer, crappy old DVD players, blu ray players, my old Boxee Box, video game systems, EVERYTHING except for the amazon device.
I have to say I have a hoohum relationship neither CEC. Being able to use my Harmony Remote on the AFTV2 is very nice, but that L A G !
Well that's one thing, but the fact that I'll turn the TV off, and go to bed. It's a real PitFA when outta the blue my TV cuts back in ~30 Minutes latter. Seemingly by itself. A problem made worse by the fact that I live in a One Room Apartment, and I'm trying to sleep.
I am having the same issue.
My TV used to automatically turn off after 30 minutes of non-use. With the Apple TV or Regular.
Since switching to the Firestick it just eventually turns black but doesnt turn off.
While it may not use a ton of energy it is still on and warm being used.
Anyway to fix this or is this because the firestick really doesnt turn off? What if I turn Alexa off in the remote?

I have the video out cable for my Dinc and It works very well, but I can't figure out a way to disable the main phone screen while I am using the TV out cable. I use it quite a bit on flights as I have some MyVu video glasses that let me watch movies on them. The issue is that the battery is being depleted very quickly due to havign the main screen on even though I am not watching it.
Is there an app or setting that will either let me toggle the main screen on or off, or let the screen sleep without stopping the video playback like when you hit the top sleep button?
I would say the screen has to stay on because if the screen goes to sleep it stops the video player app..... as for the battery you should be able to plug the charger into the side of cords adapter I know I can with mine

I have my Firetv hooked up to a large Dell monitor display and was wondering if there was a way to put the Firetv in a true hibernate mode. Right now when the Firetv goes to sleep, it still prevents my display from sleeping so the backlight remains on. I think this is due to the Firetv always being in standby mode. Is there a way to get my display to sleep when the Firetv goes to sleep? It's quite a nuisance having to go to my display to manually turn it off or having to unplug the Firetv.

The two TV's I have tried it on go to sleep after the FTV does. But there is a cheap work around. I have a older Samsung Monitor that for some reason won't sleep with my CS918S STB. I bought a cheap eForCity 3 PORT HDMI SWITCH. It comes with a remote so I programmed the port buttons to my Harmony remote. When I am done with the box I just put the hdmi swoth on the empty port. Should work for the fire too. The only run about $7 on Amazon.

Just checking if anyone has managed to solve this yet? I have the same problem - monitor backlight won't turn off while Fire TV is in sleep mode. As the Fire TV is the only device used with this monitor mounted on a wall, I really want to be able to control it with just the native Fire TV remote and not have to walk over to the monitor to turn it off...
Thanks!
When my FireTV goes to sleep, my TV stays on. Is this normal? Is this an issue with the FireTV or my TV? I'm using the XBMC FireTV screensaver from elmerohueso's repo.

If your TV can do HDMI-CEC (on Samsung they call it AnyNet+) then it should be able to turn the TV on & off.

I don't think it turns off the tv via hdmi-cec. It will turn my tv on, but doesn't turn it off - but my tv has an autoshutoff that kicks in after X minutes/hours of no activity.

I actually disabled the FTV's CEC when my screensaver is running because it would cause a TV that was already off to turn back on when the FTV is put to sleep. I suppose I could add it back as an option, but you'd need to consistently leave your TV *on* and wait for the FTV to put it to sleep. Otherwise, the FTV going to sleep would turn the TV back on.
Edit: Can you provide a reasonable use case for why someone would leave the TV on and wait for the FTV (or another device) to turn it off?

I write a 0 to /sys/devices/virtual/graphics/fb0/cec (the file that controls CEC). I then write a 1 to enable it after I put the FTV to sleep. CEC settings are not accessible via the FTV UI.

Bringing this one back from the dead..
My reasonable case for why someone would leave the TV on and wait for the FTV to turn it off is that I have small children and a wife in the house who do not believe in shutting off my 60" Plasma... It really gets on my nerves when I come home from work and I look up at my TV expecting it to be off with a red LED indication showing such, but then see no LED and a slightly brighter black background than I expect. I am not necessarily worried about the whole power consumption thing, but more worried about the life of my TV. It would be nice if it were possible to turn the TV off when the device goes into sleep mode. I have been searching the internet for an answer but I haven't been able to find anything as of yet. Your post is the only ray of light I have seen about controlling the CEC. Any ideas on how to get it to turn off the TV?
Are you using my screensaver to put the FTV to sleep? If so, you could comment out the commands where I disable CEC in the Python code of the screensaver.
If not, I don't believe the native sleep setting on the FTV sends a CEC power signal. My screensaver only does because it forces the FTV to sleep by simulating a Power button press.

Most newer tv sets should be programmable to turn off automatically when it doesn't detect a signal. My bedroom tv doesn't but I've got into the habit of setting the sleep timer. There might be a better option but I find its not worth the effort to investigate. Maybe if the aftv had cec support like my rpi (control everything with tv remote) I'd look deeper, but since i need the tv remote for volume, I don't see the point in spending much time on the sleep issue.

Just found this. I was looking for a way to disable cec awhile back on one of my aftvs in an attempt to fix a possible handshake issue.
What happens is if the aftv is powered on before the tv, the audio will cut in and out every 8 seconds until aftv is rebooted. The result is if I turn off the tv at nite, when I wake up in the morning I absolutely have to reboot aftv for it to play properly--brilliantly annoying! Aftv is the ONLY device that has cec issues on this tv.
My questions are
1. What will disabling cec do exactly? Would there be unexpected consequences?
2. When you say you write a 1, do you mean replace the 0 in the line above?
3. If this is an appropriate measure--will a factory reset in cwm bring it back to full cec support or will I need to manually write it in?
The last question is just my thinking this aftv will outlive my TV so eventually I'll want cec back.
Thanks.
Hi folks,
im running a Fire TV 2 on a PC monitor. As a matter of fact i get washed out blacks when watching movies due to the RGB limited (16-235) output of the fire TV.
My monitor wants to be feeded with RGB full color space (0-255) and does not support adjusting black levels. I found no possibility to adjust the output range on the fire TV, so it seems that I'm stuck with my washed out picture.
On the other hand on my rapsberry I can adjust the output range by simple adding the HDMI_PIXEL_ENCODING switch in the config.txt. Now I'm wondering if I have a chance to adjust the RGB output range by rooting my fire TV? Is there such a thing like config.txt which can be modified?
Any help is highly appreciated
Its Kernel Stuff (which also means, that there is probably no "app solution" for this) -
no config.txt on Android.
http://forum.xda-developers.com/nexus-player/help/ycbcr-support-t2938224
Great news, you can switch between limited and full RGB using the 24p key combo. Tested right now, works.
http://www.aftvnews.com/fire-os-5-adds-partial-24p-25p-30p-video-support-to-the-amazon-fire-tv/
When you first hold the button combo and the Fire TV starts to cycle through resolutions, you might see a black screen for a while 20 seconds or so - depending on the resolution thats on screen at that point. That means, that currently a resolution is displaied, that your monitor doesnt support. Eventually the Fire TV will cycle back to resolutions your monitor supports and you'll get an image again. During the cycle the Fire TV pulls up every resolution in limited and Full RGB mode and you can hit stop, once the right combo is displayed.
Hey harlekinwashere,
thanks for your input, I will try as soon as i get home
Hi,
unfortunately its not working for me
I'm able to open the hidden menu and it switches between resolutions (1080/720/480) and refreshrates (50/60 Hz) but not limited/full range.
Im using the latest firmware.
I'm on 5.0.5 and what I noticed is that each resolution is displayed on a screen that doesn't auto adjust for input levels, twofold. One time it produces severe black crush on my monitor, and one time it doesn't.
This happens on every resolution during the process of cycling through them.
I was pretty sure, that that was the Fire TV switching between limited and Full RGB. Its not labled that way - but its instantly obvious looking at the patterns.
Do you not see any such behavior on yours? A wild guess would be that its a handshake thing and the Fire TV only does it when connected to certain kinds of monitors - but, that would also be a bit strange ...
If you have seen the black crush (or in your case shift towards real black) color shift and have identified it as "not full RGB" - I might be mistaken - I have not measured the actual image on screen, I've just seen the picture on screen cycle between black crush and normal image on my monitor and assumed that this was limited/full RGB being applied.
Hi All,
Fire TV seems its' sending black screen to TV when it goes sleep mode which makes TV or projector stay all night.
I wonder if there's any tweak in the system level to make HDMI signal cut off when it goes to sleep mode.
Thanks in advanced.
