I have tried everything that is on the internet (plugging off TV, plugging off chromecast, plugging off TV for 30 mins, factory reset the chrome cast) - but it's still showing black screen and audio is working fine when casting.
I can't connect to a different tv as this screen is the only one i've got.
If this helps - i just moved into a new place, the tv at my new place is a lot better than the previous one (a lot newer model). But at the old place, I never had an issue with my chrome cast. Only when i moved to this new place i started getting this problem.
We appreciate your efforts. We'd be happy to take a look into this for you. Please fill out this form with all the needed information then let me know once done. Also, please tell us the make and model of your TV and router.
