Greetings,

I have a Samsung QN90AA 50 Tv and YouTube TV. Up until last night it had worked for some years.

Now there is no video or sound. The guide shows up and all the settings tabs and so on. There is even the option to resume a previously viewed show and I can click on that.

No video at all. It is stuck on  a black screen with the little circle spinning.

If I click on the resume show windows, there is a commercial for some 3 minutes. The commercial video shows. No problem. there little timer is there to show the 3 minutes going by. Then upon completion, the screen goes black with the spinning circle.

I have done the following: power recycle, reinstall, clear cache, delete Smart Hub and reset to factory specs. No change.

In looking at the nerd information there is NO "Network Activity" The connection speed shows as well as the buffer health.

Also, YouTube TV works fine on my Samsung S21, desktop, laptop, tablet and Roku device. No problem.

The Samsung TV is connected via hardware to the router. There is WiFi also. Tried both connections. Just in case there was a hard wire issue. Zero luck there.

Up until now, there was not any issue. Download speed is about 120 Mps and upload is about 60 Mps.
