Chromecast not controlling TV via CEC

brbubba 17,187 2,785 July 26, 2013 at 05:30 AM
Been playing around with the chromecast wondering why in the hell it's not turning on the TV and changing the input, presumably through the use of CEC. I found this today for anyone trying to figure out this issue.

From https://support.google.com/chrome...ic=3267370

Quote :
CEC, or Consumer Electronics Control, allows for HDMI devices to be controlled with one remote control. If your television has CEC support, you may be able to turn on and change the input on your TV using your phone, tablet or computer while using Chromecast. Please note that in order for CEC to work (if CEC is supported by your TV), your Chromecast must be powered by a power outlet.

Manufacturers often call CEC by different names, including Anynet+ (Samsung), Aquos Link (Sharp), BRAVIA Link and BRAVIA Sync (Sony), HDMI-CEC (Hitachi), CE-Link and Regza Link (Toshiba), SimpLink (LG), HDAVI Control, EZ-Sync, VIERA Link (Panasonic), EasyLink (Philips), and NetCommand for HDMI (Mitsubishi).
Have not tested this yet, can anyone comment on actual testing?

Hardly anyone has theirs yet. I don't think my new LG has this feature and I plan on plugging it into my amp anyways. It's not really a big deal for me but it makes sense that the Chromecast has to have constant power (the wall) to turn on a device thats off. I know there were people on the AndroidCentral forums who had theirs and were answering questions yesterday.

How do you like it so far? I am excited to get mine and should have choose the faster shipping.

AFAIK, any TV made within the last 3 years should have CEC. My LG 50PA5500 has it and it's the low end of the plasma line, so they all should have it.

So far, it's another google beta product. Youtube works very well, but you also quickly realize how crappy 90% of youtube videos are in terms of quality on a 1080p 50" TV. Haven't tried Netflix, honestly doubt I will use it long term as I'm not a big fan, but I could see a massive appeal for diehard Netflix users. Sent a few chrome tabs from the laptop, worked nicely, haven't tried hulu or anything else. For me the appeal would be sending a youtube video or pandora station to it without having to fiddle with the remote, turn on the TV, change the input, etc etc. Honestly, I can see the full potential but I think we are 6 months out before getting there with more app support. In the meantime this is definitely a neat device but way over hyped right now. Right now the only people that should be buying this are Netflix lovers who have been holding out and never got a Roku.

You're missing the point here.

In order for the Chromecast to send a "Power On" command to your TV, the Chromecast itself must be powered. If the TV is off, the Chromecast gets no power from the TV's USB port. What you need to do is run a USB cable from the Chromecast to a wall outlet. (Of course, you don't plug the USB cable into the wall outlet, you plug it into a USB charger, such as an iPhone or other USB to AC power adapter).

This is a pain, CEC is not working at all on my LG TV. Even plugged in externally it will neither turn on the TV nor change the input when I send a video to it.

Got one last night (the truck had just been unloaded, lucked out). Not very impressed (happy it was only $13 after taxes). Installed Chrome on my desktop, installed the casting extension, and tried to cast The Colbert Report. Didn't work -- it starts, then the video freezes, but the sound continues. Tried it with YouTube, works. Couldn't care less about Netflix, as all my devices have Netflix.

Then I got a message in my browser that network performance was slow -- hard to believe, as I still could see it flawlessly in my browser. Fiddled with options, still no go on The Colbert Report. Tried some other videos from other sites -- same thing: starts, I can see a video for a few seconds, then the video freezes, sound goes on. This thing is going into the drawer until G. makes it a bit more useful. One more failed Google product

No, your PC is just crap.

I had this same discussion with another user in the main thread..they had a Lenovo laptop with XP and only audio would come out (XP is straight up not supported with Chromecast, so I'm surprised even audio came out). For me with my Dell running Windows 8 (also a few years old), it had a Core Duo and I had to change my settings to 480P for a decent streaming experience, I would get audio and video, but video was a bit laggy on 720P (default) and 720P high bitrate .


However on my Core i5 desktop everything runs flawlessly with no lag or issues on 720P high bitrate. Colbert Report, Amazon Prime..anything. Works great.


Don't blame Google because your tech is not up to snuff.

Has to be LG or you got a defective unit.


Three TVs here:


Panasonic with VIERA Link - Works great. TV will turn on in a powered off state when something is cast and switches inputs accordingly.


Sony with Bravia Link - Works great. TV will turn on in a powered off state when something is cast and switches inputs accordingly.


Toshiba with REGZA Link - Some setup required. Did not initially turn on TV in powered off state. Checked manual, had to go to REGZA Link options and enable "TV Auto Power" to ON. It was set to off. Works fine now and switches inputs accordingly.


The Sony and Toshiba have USB ports but they shut off when the TV turn off so external power is required.


OP I suggest you check your settings as well..it may have been like my Toshiba. Go to SIMPLINK options and make sure "Sync Power on" and "Direct Play" are enabled.

Um, I have a Core 5 desktop running Windows 7 Pro. Don't think it's the computer's speed or power. The wireless is N 300, with both devices within 3 (Chromecast) and 20 (desktop) feet from the router. As I said, crappy product, but will keep it in case they have better apps/support/upgrades in the future. If all you watch is YouTube, then it's OK.

Have you tried downgrading the settings and seeing how it turns out? And Core i5 what? 1st gen? Clearly something wrong on your end, and the hardware on the Chromecast is more than adequate to run what it currently has on it. Not a crappy product, just because your end has issues. It works flawlessly for me. Something is wrong with your hardware.


I use it for Amazon Prime, anything I can stream in Chrome, movies media, music, all in 720P high bitrate. All work great. It's your hardware. Try troubleshooting. Sorry.

There's no way in hell even a 1st gen Core i5 can't transcode and stream to this device. It's more than powerful enough. There's something else wrong here.

Steve Gibson on password policies [grc.com]: I mean, I don't get this change it every eight weeks. ... It's not as if passwords are traveling by camel after they've been stolen, going to the bad guys, and so there's, like, some weird eight-week window, like, oh, we're going to change your password so that the stale password no longer works. ... And all this does is make IT people despised because users, who are not dumb, they think, why am I - why do I have to do this? What problem is this solving?

I'm just spitting out what Google says...

...you would probably need to downgrade to standard quality with a 1st gen.

The device is not setup to transcode anything, It's not mirroring you screen, thats why you can go do other stuff while things are playing. The CC itself goes out and fetches the stream your watching on your device and plays it directly. Not sure why the requirements are so high.

It's doing screen mirroring using webRTC for everything except netflix, youtube and google play store items. Unfortunately the software isn't released yet for things like hulu and amazon prime content.
