My RPi2/Kodi goes nuts when I turn off the TV+AVR. It constantly sends some signals that turn on the AVR, turn off the AVR and the Standby LED from my TV goes crazy, like it is turning on and then immediately off again. There is some fighting going on over something.
Setup: Philips TV connected to Sony AVR that has Chromecast as HDMI1 and RPi2 running latest stable OpenELEC connected to HDMI2. CEC is enabled in Kodi with everything on OFF or IGNORE (like auto power on/off).
Here is the log where I turn off the TV and the crazy starts: http://pastebin.com/di8vB7sQ
Problem started a few weeks ago or so. I had the OSMC Jarvis build running when it came out without a problem and suddenly the problem started happening. It's the same with the latest OpenELEC (Isengard and Jarvis builds) now.
If I disconnect the Chromecast this "CEC command fire" from Kodi stops. I had this setup running now for 6+ month and it worked without major problems.
Anyone know what is going on here? I asked in the Pulse-Eight/libcec Github but no one answered there.

The setup was fine, connected to my network, played Netflix and Youtube from various devices (phone, laptop, computer) no problems! (Interested in the Plex thread and others on here for locally stored video.. )
What is happening is very strange, however. I have a TV with multiple inputs (typical these days, right?) but after I've been 'casting' to the Chromecast, it takes several tries to change away from that input to another input (my Xbox, or HD antenna).
ALSO - the TV powers itself ON after a while! WHY IS THAT? I left and came back home and thought I had left the TV on - which is not like me at all! And later that night it turned on AGAIN after I went to bed. I unplugged the Chromecast just to get it to stop, but ideally, I would want to leave it plugged in all the time.
What is making the TV turn on?
Will moving my TV input to anything other than the Chromecast port stop it?
Is there a soft power-off option for the Chromecast device?

Sounds like you're having issues with their chrome cast's HDMI CEC. It can be used to automatically change inputs to the one the chrome cast is using and even turn on tvs.
You could disable HDMI control for your TV and it would prevent the issues from occurring.
Every manufacturer has a different name for their HDMI Control feature.
Who makes your tv, OP?

I would suggest to just unplug the USB when not in use if your TV is turning on, I know my brothers TV its a westinghouse turns on anytime something connected to it turns on like the xbox or ps3 or laptop
not so good to know. hope its fixed soon

It's a Toshiba flat-screen, don't know the model. I'll put more detail up tonight when I can look. :silly: I also need to try having it off the Chromecast and starting a session and seeing if it draws the TV to that input. THAT would be nice, but the auto-powering on is a bad bug in my opinion.
My TV turns on automatically when just about anything powers on before the tv is on. Say I turn my ps3 on 1st, it will turn it on. Or plug a USB Flash drive in, turns it on. But, once in the HDMI spot, I can shut it down and it stays off. Very strange.

I have one TV in my house (Toshiba 55HT1U) that keeps getting turned on by the Chromecast. I turn the TV off, and then with a few minutes, the TV will be back on again. Unplug the Chromecast, and the TV stays off. I have tried multiple Chromecasts with the same results, I disabled Regza Link (Toshiba's HDMI-CEC), and it still keeps happening. This also happens whether the Chromecast is connected to my TV or to the receiver which is then connected to the TV. I have read where this particular TV suffers from this issue with other devices, but I wish there was a way to turn it off from the Chromecast end.
Right now, my solution is to go and unplug the Chromecast when I am not using it...hardly an elegant solution.
Have you check the manufacture website of your TV. I know some TV within the last few years, if it have a USB hook up, you can typically update the TV Firmware it may solve your problem. Just a shot in the dark. Also Chromecast is also getting an update.

I have seen where some people have tried the update and it made no difference, but I will definitely try this when I get home tonight.
Find your HDMI-CEC options (whatever Toshiba calls it) and turn on HDMI-CEC but turn off Auto power. That will allow HDMI-CEC to switch to the right input but will not allow the HDMI-CEC to auto power the TV.
I have the exact same problem with a Toshiba 46G300U1 so let me know if you find a solution. It seems like a bunch of the Toshiba's all have this problem and I doubt Toshiba is going to fix it. I've tried various different kinds of options (connecting the Chromecast through a cable, a HDMI switch etc.). As long as the Chromecast is switched on and connected to the TV it always turns on automatically. Obviously disabling HDMI-CEC doesnt seem to help. I suspect there is a bug in the Toshiba that still keeps acting on HDMI-CEC signalsI am planning to file a support case with Chromecast as they are more likely to fix the problem (maybe an option to disable CEC on the Chromecast) than Toshiba. But since that is unlikely I am thinking maybe I can try a cable that doesnt properly support HDMI-CEC. It seems CEC is a separate wire and there are lots of people online complaining about cables that don't support CEC.
Try not powering your device via USB from the TV. (If you are) My LG TV seems to have issues with CEC from devices that get power from it via USB. Does weird stuff like this
So I tried updating the firmware on my TV...they said just put the new firmware on a USB stick, then plug the stick into the TV and it will automatically prompt you to start the install. Well, it didn't. I tried 2 different USB sticks with no success.
My "fix" was to just power the Chromecast WITH the USB port on the TV. That way the Chromecast is off when the TV is, so it won't try to turn it back on.
Great idea. I am connecting my USB cable to the TV's USB port for now. I might try connecting the Chromecast via my audio receiver later on. FWIW the firmware update did nothing to solve the issue on my TV.
I don't want to disable CEC on my TV, because I'd still like to have the CEC capability to turn on/off my home theatre automatically along with the TV. I can use USB power from the TV to power my Chromecast, but once the TV is on, my home theatre mutes automatically because it gives up control of CEC to chromecast. It's an unfortunate software decision made by Sony, the maker of my home theatre. I want the home theatre speakers to stay active, but Sony has programmed it to mute when another device on the same HDMI bus takes CEC control.
If you don't want your Chromecast to be a CEC-control device, meaning you don't want it turning your set on at all, or you don't want it overriding other CEC devices, just order lindy-usa.com part number 711110-1, which is a HDMI CEC Less Adapter, Female to Male, and put it inline with your Chromecast. It disables the CEC sense line from your Chromecast to your TV. Problem solved. Neall
I hope the forum can help. I have read FAQ and some 5 pages of topics without finding anything.
My Chromecast keeps losing its connection to my WiFi when CC is not in use. Standard routine goes like this:
When deciding to use the CC, I always find that it is not connected to my WiFi, even though the Chromecast is always AC connected.
I try rebooting the CC (by unplugging the power and plugging it in again)
Observing that the CC does not pick up the WiFi, I reset the WiFi router
When that does not cut it, I repeat step 2, and then I am on.
Sometimes I even need to repeat 2-4 to succeed.
After using the CC, some time later (minutes? hours?), the process needs to be redone.
But once connected and casting, the connection is flawless!
By coincidence, my ISP sent me a new router whilst I was troubleshooting these problems, but even switching hardware has not helped.
My current router is a MediaAccess TG788vn v2, but as indicated, I suspect it is not the problem.
It is set to the recommended 2.4 GHz 802.11 b/g/n by default, and since it works on-and-off, I suspect it is not a channel issue either?
Thanks for any inputs.

Oh, a Thomson router... (I used to work with some of those folks).
Sometimes one of my CC's drops off for a bit (I can tell by the blinking white LED) then reconnects shortly afterward.
I've never had it disconnect while in use though.
Are you using the HDMI extender? If not, try that.
Also check your TV for any CEC (aka Simplink, AnyNet+, Bravia Link) settings to shut off the device when the TV is turned off. I don't think it shouldn't affect Chromecast, but still good to check.
If your router has any power-saving functions, try disabling those too - maybe it's dropping the transmit power when idle enough that CC loses it. I couldn't find the manual in a quick search.

Tried the HDMI extender to no avail.
My TV is a 2009 Panasonic TH-42PX80. It appears that it has some CEC features, but I have a hard time finding the exact setting in the menu. Turned off a few "auto off" things though, without any benefits.
I hadn't the time to tweak any router power-saving features yesterday, will look in to it today.
I sure hope someone has seen and solved this one before, despite not seeing it in FAQs ...
Also check your router setting for DHCP and see if your Client Lease time is set too low.
DHCP should not expire more than once a day. 1440 Minutes (once a day) is usually default on most routers but sometimes it gets set to much less and it could be that it's losing connection after casting because the DHCP expired but couldn't renew while it was casting so once streaming is done it renews and reconnects.
Longshot though of that being your actual problem...
Resolved.. I think! A friend with another CC strongly recommended experimenting with the channels. I downloaded inSSIDer app and found a better channel.
Tonight I had several flawless connections.
I think Google's official troubleshooting on this could be more precise. Here's to hoping it is picked up or other users at least stumbles on this thread.
Thanks for all inputs.
I had the same issue, ended up RMAing it...Thing just wouldn't stay connected. New one never has the issue...
Hello,
I've got a problem with my setup.
I connected Chromecast through the HDMI to VGA adaptop (with audio output) - the setup worked fine straight after connecting power to the Chromecast.
Everything was fine for a day or so and then I turn on the TV and the screen was black.
I checked the connections etc but no joy - I tested all components separately and everything works as expected.
I think the issue might be related to the recent Chromecast update... is that possible?
Does anyone else has a similar problem? What I could check/do to sort it out?
Thanks!
Hi,
Not sure if this can help, but I had a similar (blank screen) issue when the chromecast device was starting up with my monitor turned off (connected with a hdmi/analog audio splitter - for audio transmit only). After turning the monitor on and restarting the chromecast everything seems to be fine, guessing chromecast would initialize the display at boot time only.
I have a LG 42ld450 TV that seems to not like my Chromecast very much. Whenever I plug it from either HDMI port, it just goes berzerk for no reason and turns on and off repeatedly. Sometimes it eventually proceeds to display the stream as normal for hours, sometimes it just lasts a little while before resetting over and over. It seems to be entirely random. I have disabled CEC to no avail. It works fine with my other TVs.
Could it be an electrical problem? I have it connected to a power strip that is connected to a power cord that ends in two prongs (even though it has a three-pronged input). However, I doubt it could be this since it only happens when the Chromecast is plugged in.
Sounds like a TV issue more than a Chromecast one if it doesn't have any issues with any other TV

If you have a friend who as a chromecast , ask him to do an exchange for a couple of days for testing purposes ..
Then you'll know if it your tv or chromecast
10$ its your tv or if you can turn off simplink in lg setting see if that help
