Have New LG 47LA6200 Smart TV, SIMPLINK ON, AUTO POWER ON & Cc can't turn TV ON

Ok guys, I need some help. I have a brand new 2013 LG LA6200 Smart TV. HDMI-CEC (SIMPLINK) on the LG is turned on and so is SIMPLINK Auto Power is set to on. I have the Chromecast dongle powered from the USB power supply rather than the TV USB port. Here is the problem. When the TV is off and I select Chromecast Google Play movie to be cast, I thought Chromecast was supposed to turn ON the TV and flip to the right input and start playing. However the TV never turns on. It is just sitting there turned off. However if I manually turn it on, the correct input is selected and the movie is streaming. So... how does Chromecast is supposed to automatically turn the TV on?? Cause in my setup it ain't happening. Any help will be greatly appreciated. BTW, is there a Google Chromecast place to post questions like that? Thanks.

You're not the only one. I have a 2013 LG TV (LN5700) and auto power does not work. Same setup as you-- Inputs are correctly switched but the darn display won't turn on.
I'm not sure whether the problem is with the Chromecast itself or the display as I don't have any other HDMI-CEC devices to test with.

I have an LG LM4700, and my AVR with CEC control never turned on/off my tv, but my tv would turn my AVR on/off.
I read on a forum post somewhere (take with a grain of salt) that LG didn't fully implement the full HDMI-CEC spec with SIMPLINK.

I also have an LG BP530 a Blu-Ray player which also has Simplink (HDMI-CEC). With both the TV and the Blu-Ray player OFF, pushing the front play button of the Blu-Ray player, turns the blu-player ON, turns the TV ON, switches to the right input and plays the DVD. In other words the Simplink (HDMI-CEC) protocol as implemented by LG for all their LG devices WORKS.
I'm thinking that HDMI-CEC may be a "standard" but every OEM has only tested their implementation with their own stuff. That is why each OEM uses a different name (Anynet+, bravia link/sync, simplink, Ratga link, etc...) instead of HDMI-CEC. I bet if you put the HDMI signal through a scope and try to isolate the control signals you will find that from each OEM they are just a tad different (maybe a bit longer pulse..).
Google could fix this in firmware of course but they will have to test for each brand individually and in the end possibly they will have to have an option to select the type of TV the user has for the differences in HDMI-CEC implementations. Either that or each OEM will have to update their sets to more correctly adhere to the standard.

This is why I never put much faith in HDMI CEC when I use to install home theaters and media rooms. It always led to inconsistent operation with some devices working and others not. I would always turn that feature off and program a universal remote for the customer.
At least it is switching inputs for you, though. That to me is the most important. Are you mainly using a phone/tablet for chromecast or a PC? If mainly using your phone/tablet, you could use LG's app to turn on the TV before casting. I know it is not ideal, but unfortunately HDMI CEC was a standard but all manufacturers implemented it differently. There is currently no way for chromecast to work the way it was demoed to work across all manufacturers' TVs.
EDIT: Some ray of light is that LG is a hardware partner with Google. Chromecast support might get pushed to your current TV and/or Blu-ray which would solve your problems. If nothing else, I suspect LG to come out with a new Blu-ray player that supports Chromecast.
EDIT 2: I forgot that LG's network protocol does not support turning "on" the TV or Blu-ray so using LG's app will not help you.

In fact I have 3 Chromecasts (for our 3 TVs) and the Chromecast input switching works so well on the LG that I hooked all 3 on the LG and I was able to cast from Chrome at will to one at a time and they would automatically switch to the correct input on each and every time. Now if they can fix the Auto Power ON I will be all set. I also think that LG and Google have a good relationship so they can hopefully work out who will update what (Chromecast or the LG TV) to fix this. I certainly will continue bothering them both (Google and LG) till they fix the issue.

Sorry but no dice. Simplink settings: Simplink ON, Auto Power ON. The TV recognizes the 3 Chromecasts plugged into the 3 HDMI inputs with the Simplink logo on the input TV screen, but it refuses to allow them to turn the TV on. All 3 are powered with the external power brick. However, once the TV is manually turned on, the Chromecasts do switch to the correct input when something is cast to them. So as far as the 2013 LG model 47/50/55LA6200 is concerned, the only issue is that Chromecast will not turn the TV ON even though the Auto Power setting of Simplink (LG speak for HDMI-CEC) is on.
Either Chromecast or LG need to update the firmware for their devices, as I have said before the LG Blu-Ray player with Simplink does not have that problem and is able to turn the TV on just fine.

Just got Chromecast on Monday - some issues encountered so far

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.

Chromecast keeps turning my tv on

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

Having problem switching back to regular tv

I received my chrome cast from Google. After watching You Tube via my Note 2 on my HD tv, I try to switch to regular TV on HDMI 4. It would not switch to regular tv. So I had to reset the FIOS receiver which brought the tv back. This happened again today. I have a Sony HD tv.
Also, how do i turn off chrome cast.

Have you tried turning off CEC? This is what allows HDMI devices to tell your TV to turn to the right input (if you on standard TV on HDMI 1 and chromecast is HDMI 3 it'll automatically change input when you cast content)

Chromecast HDMI CEC to LCD monitor?

Has anyone used this for connection to a LCD monitor instead of a normal TV?. Specifically, I'm wondering if the chromecast could autoselect the HDMI input whenever casting was turned onto it. So the default input would be VGA/DVI from my PC, and then when activated, the monitor would switch to the HDMI input from Chromecast, and once done, back to the PC. From what I've read, the Chromecast uses HDMI CEC to do this with normal TVs, but not finding a lot of information as to whether or not it would work with a monitor. If I need to test myself, I understand - just curious if someone else has ever tried to do the same thing and had personal experience.
Thanks!
