Regardless of whether I'm on YT, Netflix or anywhere else, my TV only plays the sound and then there's only a black screen?

Regardless of whether I'm on YT, Netflix or anywhere else, my TV only plays the sound and then there's only a black screen.

Who knows why and how I can solve it? 🥺

Maybe the device is defective or the services are not (correctly) activated.

Can you watch TV normally with it?

Thanks for the tips!

I found out what it was, but thank you very much anyway, that you wanted to help me!

With pleasure.

Please post the solution for those who read along.

So, thanks to everyone who wanted to help me.

I already found the solution myself, but I had to do a new update on the TV.

I did it and afterwards everything worked again.
