Hi! Have tried to use it on another TV. If it works on another tv the tv
might be the problem or the HDMI ports of the tv. If it does not work in
any tv, please contact support, as you may need a replacement:

Hello Graham1, try to reset the Chromecast by pressing the button for
about 10 seconds until it shows that it is resetting. Then you will have
to do the setup with the new wifi and Google Home App.
Hi Skyler209, Unfortunately, it is not possible to reset remotely. Once
reset, the cameras will need to be turned on physically as they do not
remember the wifi, so you can not find them close to the wifi if you are
not present. Sorry about that.
