My TV's HDMI port into which my CC was plugged one day starting giving me a "No Support" message. I had been using the CC extension as recommended for a better reception. As with the previous poster, I unpluged the extension and used the CC directly into the HDMI port and the TV again picked up the CC. So the extension may help or hinder a TV from making a good HDMI connection. Thanks everyone for all the input.

Hey Everyone! I have a 24" Element LED HDTV that I plugged my CC into and l was getting the No Signal display and I tried the few suggestions listed to no avail. I then got my CC to display on my TV by connecting the CC usb straight into my USB on my TV.
Hope this helps!
HAVE A GREAT ONE!

Ah..

For others just reading this thread... (true for both version 1 and version 2 Chromecasts)...

The Chromecast needs power via the usb port....HDMI doesn't provide power.

Does any have solution for this, it is the most common topic without any solution.

Restarting TV doesn't work...
Plugging CC after starting TV doesn't work....
Factory Reset doesn't work.....

Any help, solution would be appreciated. Thanks

In this case Nothing will work if you keep trying..
Try this:

1.unplug your tv. (totally disconnect power supply)
2.After 10 min plug the power supply back.

This worked for me and I hope works for you too.
Remember: Unplugging makes all the difference here. on/off with remote wont work.

Hi there
I have had this problem as well. Spent ages on phone with Google and – noting that they were very helpful and called back several times with additional suggestions – they finally agreed to replace the Chromecast. When the new one arrived I had the same problem!! This thread has been great and I worked through several suggestions – so thank you everyone for the very clear instructions! This is the one that worked. (I am sorry for those who gave up after long efforts – if we had found this first it would have been great! So – hope this helps someone.)
Possibly important notes:
- My Chromecast is a version 2.
- I had slightly different results with different HDMI Ports (there are 4 on my TV – some just said ‘check signal cable’, one seemed to want to start the loading process then went to a blue screen and wouldn’t come out again, and one would display ‘Chromecast’ across the bottom of the screen and then the G would form, but then disappear and go to the ‘check signal cable’ message.
- I tried restarting the TV in several ways – turning it off and on, powering it off and unplugging the power cord, pulling the power cord and relogging it after a minute or so.
- I tried restarting the Chromecast and resetting to factory settings (hold the button for 30 seconds or so until the light works through several modes and back to steady white).
- My TV is about 10 years old – Samsung LA40C650L 1MXRD

Specifically, what did the trick was unplugging the TV while it was powered on, and leaving it for the full ten minutes as suggested by shreyans khard.

I restarted the TV with the Chromecast attached to the HDMI and powered through the USB on the TV. Voila!! It worked – I am set up, the Chromecast has updated and I am watching Netflix!

Hi, I had this issue. The CC worked fine for months, then I disconnected the TV power and it wouldn't work again. It remained plugged in throughout, but displayed searching for input.

I found that by using a cheap HDMI splitter input ensured it works. This is a 3 port into one HDMI input selector, which essentially works as an HDMI extension cable. Now works fine.
