So when I turn it on the screen boots the chromecast normally and then a loading ring comes up and spins a few times and then the screen goes black. I can still cast to it normally and the sound plays as it should and my home device says it's connected and I can hear it but black screen. I have tried a reboot, a factory reset, unplugging, switching hdmi slots, removing the device and adding it again. One post suggested holding the power button in until you get past the chromecat boot screen but that didn't work either. Any help would be greatly appreciated. Thank you in advanced for your time and effort.
Thanks for reaching out and for being a step ahead of us. To confirm, do you have a separate Chromecast dongle? If yes, what type of Chromecast device do you have? Has there been any changes in the router settings?

Let me know how it goes.
