Chromecast does not turn on HDMI-CEC 2013 LG 47LA6200 smart TV about google-cast-sdk HOT 32 CLOSED

Similar issue on an LG 39LN5300. Chromecast is not detected as a Simplink 
device resulting in CEC control functions not working properly.

Similar issue with LG LM7600 47". TV input shows "Simplink" under the 
chromecast, and will successfully change inputs, but fails to turn the TV on. 
The Chromecast is plugged into an outlet, not the TV's USB.

What is interesting is that on the LG LA6200 I have no problem switching 
inputs. The only problem on the LA6200 that I have is the Chromecast is not 
turning the TV ON. In fact the TV has 3 HDMI inputs so I hooked all 3 of the 
Chromecasts that I have and I'm able to switch to each Chromecast by casting a 
YouTube Video to each one. So the switching part at least on the LA6200 is 
working perfectly. I also made sure the TV was updated to all the latest 
versions of firmware when I got it, so I don't know if that has anything to do 
with it.

Also the Chromecast got updated to 12840 firmware with no difference in 
results. Still I'm not able to turn on the TV, but switching still works.

I just got my Chromecast and hooked it up today. I'm having a similar issue 
with a LG TV although it is reversed. My Chromecast turns my TV on but does not 
switch the input. I know the Simple Link works because when I turn on my LG 
Blu-ray player it turns on the TV on and switches to the correct input.

My 3D LG TV Model # is 47LM-4600 

same issue. 47lg50

I too faced the same issue in my LG47LM6200. I was not able to switch on the TV 
using the youtube or netflix app from the mobile. But the input mode in the TC 
shows as Simplink. 

Was very happy, when i came across the below from google 

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).

WIll wait for a resolution on this one.

I have an LG 55GA6400 and it doesn't seem to work at all as a SimpLink device. 
The input doesn't change, the TV doesn't turn on. I have the ChromeCast 
externally powered via USB and a wall wart, but nothing happens when I connect 
to my ChromeCast via Netflix or Chrome.

To everyone:
Make sure Simplink is turned on your LG TV. LG ship their TVs with Simplink 
turned OFF by default. Go to your Input screen of your LG TV and you should see 
the HDMI inputs that have Chromecast plugged in should be identified as 
Simplink. If they are not, then your TV's Simplink is NOT turned on.

I have a LG 47LA6200 and I have the same issue. I have tried to connect the 
chromecast from HDMI ARC, HDMI MLH and the Normal HDMI port and non of them are 
turning the TV on. It  can swithc the inputs properly when I strem something if 
the TV On.

I have checked the ARC properties is in under audio settings and also I have 
checked from inputs the simplelinks settings is active and able to turn on the 
TV.

BTW, Does anyone could power the chromecast with rhe HDMI 1.4 (ARC) port of the 
LG TV without the external power?

I have tried with an old Samsung Plasma and a Sony Bravia LCD tv and for both 
of them the ON function is working.

To #12, I don't think the Chromecast can be powered via just the HDMI port. It 
needs either a USB port or external power.

I assume when you say that you tried it with a Sony Bravia and Samsung Plasma 
that the ON power worked, you must mean that the Chromecast was able to power 
on the TV, right? I assume you used external power to chromecast in those cases 
too.

I think the issue is with the protocol that LG is using with the HDMI-CEC 
implementation. In other words the Chromecast sends the right signals for the 
TV to turn on but LG's implementation is different enough to not mean the same 
thing that it means to Samsung and Sony. If supporting LG's implementation 
breaks all the others, Google will never implement it. Maybe they can add a 
flag specific for LG that you can set from the Chromecast setup app. But then 
you make the installation a bit harder for the novice user. I think it would be 
better if LG fixed their own implementation with an update to their Smart TVs 
to be more consistent with the HDMI-CEC standard like Samsung and Sony and 
possibly others.

to #13 Yes I meant that, in both cases It was requiered to power it with 
external usb source for the Sony and Samsung TVs and it was capable to turn the 
TV on and switch to to the right input.

What I have understood is that the chromecast can be electrical feed by the 
HDMI data feedback pings if the TV HDMI version of the is 1.4, in the google 
presentation they were have it connected to a samsumg smart TV and the camara 
show it ON without an external power source.

Yes, I guess you are right, but at less google should inform in the 
troubleshoot page about this issue or non proper compability with LG tvs.

Anyway, I am happy with the chromecast and is much easier and quick that use 
the smart TV functions, my comment is just to help to the community due it was 
hard to find information related to this issue.

Apparently LG misrepresented the capabilities of the 55GA6400, it does not
have HDMI CEC/SimpLink. It's not a problem with the Chromecast, but with LG
and their misleading marketing.

#15, All of the LG smart TVs have SimpLink. That includes the 55GA6400. But to 
turn it SimpLink ON you have to go to the Input screen rather than settings. 

There is no option for simplink on the inputs screen...

#17 - Both of these links say that the GA6400 has Simplink

Since this SmartTV has Google TV and Google TV has a different interface, maybe 
it is in a different location. Try all the settings options.

Nowhere beyond specs does the documentation say anything about simplink

There is not a TV in the last 3 years that does not have it. And since it is in 
the specs it is there. Maybe you should call LG's product support and ask them.

Called LG and confirmed, the documentation is wrong and the 55GA6400 does
NOT have SimpLink.

LG 32CS560
Powers on TV, will not switch input, not detected as SimpLink device.

Same problem with TOSHIBA 40S51U TV - Chromecast will not turn TV power ON 
(except for the 15 seconds or so after power the TV has been turned OFF and the 
power light shows RED when it will turn it back on, otherwise once the TV goes 
to standby, Chromecast will not turn it on). Toshiba calls the feature 
HDMI-CEC. It's enabled. It works with the Sony BluRay player that's connected 
to the TV. Chromecast is powered externally.
It does switch the input to the Chromecast if the TV is powered on and casting 
started when tv is on a different input.

I have an LG 32LE3300 with simplink(old vers, not smart tv) I can start the tv 
from the cromecast (pluged in the wall) with simplink on, but it doesn't change 
to the needed input. The only time I managed to make it change the input, with 
the chromecast in HDMI1 port, power from the wall, I reset the chromecast to 
factory settings when it booted I received a mesage from simplink that is 
chaging to the simplink device and that was pretty much it, after that still 
noyt changing input 

Same problems with lg42LD550.
Simplelink is on.

Similar problems with my LG 37LH7000.
Chromecast is connected to external power (not USB) and SimplLink is turned on 
in the TV Settings, however when I press the SimpLink button on my remote it 
says 'No SimpLink Device'.  Starting a cast does turn on my TV (at least from 
Chrome browser, YouTube & Play Movies Android apps - not tested others) but it 
never switches to the correct input.  It's clear via this thread that for some 
people the auto-power doesn't work, and for some like me it's the auto-imput 
selection that doesn't work.  It seems to me like it is LG's implementation of 
HDMI-CEC that is the main problem, as LG themselves says that it only 
officially works with SimpLink branded products.  Hopefully Google could reach 
out to LG in order to bring about a (software update) fix?

I'm the original poster of the issue, and starting with firmware 14975 or 
14651, my chromecast is now able to turn the TV on (couldn't before) and change 
to the correct channel like before (changing the channel was never a problem). 
My TV is an LG 47LA6200. I can't tell which one fixed the turning on the TV 
issue because 14975 version updated quickly after the 14651 so by the time I 
noticed the difference the version was already 14975. The setup is exactly the 
same as the #1 post above.

I have the same issue as the original poster. I have a LG 55LN5600. Update 
14975 seems to have broken things. Chromecast will no longer turn on the TV via 
simplink.

same problems with Samsung UE46F6510

Fixed for me as of 1-2 months ago on LG 47LM7600.

My LG 42LB5500 won't switch imputs. It does turn on though. Please, look into 
the issue.
