Chromecast No Signal Try Different Input

[joanneinfla]

Every other day I turn on my tv, the screen is blank and a small label in the corner says, "No Signal.  Try Different Input"

The only thing that seems to work is to unplug the chromecast power from the back of the tv and replug it, which should not be the solution here.  

Devices:

Chromecast 4k (purchased 7/2023)

Sony Bravia (purchased 11/2022)

Sonos bar (2017)

I use the chromecast remote to turn on everything.

So far it has only happened on this Sony Bravia tv - not on my newer samsung tv (we we don't watch the samsung too often so can't be completely sure about this)

All products receive latest updates.

This is the second chromecast to do this.  I exchanged the first one (7/2023) within 14 days because I thought I had a defective one, but it's happening to this one too.

Anyone have this issue?

Hi joanneinfla,

Thanks for reaching out. We know how it feels when something isn’t working as it should. A few questions: when did the issue start? Were there any recent changes made? What’s the status of the LED light on your Chromecast device when the no signal pops up?

Give the steps below a try and let me know how it goes:

1. Check the HDMI connection and make sure it’s fully plugged into the TV’s HDMI port.
2. Make sure the TV is tuned to the same HDMI input where the Chromecast is plugged in.
3. If applicable, try another HDMI port on the TV.
4. Check if your HDMI cable is compatible.
   1. Note: Since you have a Chromecast with Google TV (4K), make sure the HDMI cable supports 4K and HDMI 2.0. For more information, go to Requirements for Chromecast devices.
5. Make sure their Chromecast device is on the latest firmware version. 
6. If possible, check if your TV is on its latest firmware version.
7. Try a different TV if available.

Keep us posted.

Best,

Dan

Thanks for your reply.

To answer your questions:

-The issue started within days  of installing for both the first chromecast and this second one.  I returned the first one assuming it was defective and purchased this one, but have the exact same issue.  First one purchased in July 2023 and this second one at the beginning of August 2023.  

-No changed made other than adding/using the Chromecast.

-Have not been able to check the status light as it's behind the television and not easily visible.  I will check next time it happens.

1.  Fully plugged in

2. TV is tuned to  same input

3. Will try another port

4.  I'm using the chromecast-included HDMI cable

5. All updates have been installed

6. All updates have been installed

7. I have a chromecast (purchased 7/2023) on a samsung that has yet to have this issue.  

A google search brought me to an entire thread dedicated to this very issue with dozens of people with the same problem, so it's definitely not just me.

Update:

In further research for our tv, sony listed HDMI 4 as the 4K port, so we moved the Chromecast from HDMI input 1 to input 4 on our Sony TV.  

The next day, the same "input" message came up again. 

I have attached photos to show the message.

The light on the Chromecast was white.

In order to clear it, I have to unplug the chromecast and plug it back in.

I have the same issue. Bought a second Chromecast with Google TV thinking the first one was faulty. Now it’s almost everyday I have to unplug and reconnect. Very annoying!

[joanneinfla]

I posted an update...hopefully it can help you too.

Okay, my neighbor - he owns a company that does smart home devices as well as audio/visual/whole home entertainment- he works with chromecast and google smart home almost exclusively and has had this happen to some of his own clients, did this:

Changed the remote from using HDMI CEC to use Sony IR to power everything on/off.

It has been 5 days and "no signal check input"  issues!

To summarize:

-Sony TV

-4K Chromecast

-Sonos Soundbar

-Use chromcast remote to power on/off devices

Would get a message on tv screen upon power on that would say, "no signal.  Check external input..." almost every time we powered on the tv.  4K Chomecast was new and updated so we thought it was faulty and exchanged it. The new one still did it, but it only happened on our Sony TV - has not happened on Chromcast 4K on our Samsung.

My smarthome techy neighbor offered the above solution.

Aside from the message no longer popping up, the remote button "Youtube" that I had assigned to power on the tv and open YoutubeTV no longer works as a "power" button, just a youtube app button now, which I'm fine with.

Hopefully this works long term and helps anyone else that happens upon this thread.

Thank you. Can you confirm which setting you changed?

[joanneinfla]

I'm not able to ask my neighbor right now, but i found this online, maybe it will help?

Turn on the connected device. To enable [HDMI CEC Settings], press the HOME button, then select [Settings] — [BRAVIA Settings] — [External inputs] — [HDMI CEC Settings] — [CEC]. Activate HDMI CEC Settings on the connected device.

That answer I posted was for a sony TV.  I am pretty sure my neighbor did this for the Chromecast remote - not the TV - but same basic steps.

Hi there,
 

We’re glad to hear that this has been sorted out, and thanks for sharing your resolution here, joanneinfla!
 

Dtforbus, if you can’t find the CEC settings on your TV, I suggest that you contact your TV manufacturer. Let us know how it goes.

Best,
Alex
