Blackouts of image and sound

Unplug everything.

Plug gateway back in and wait for normal operations.

Plug WAP back in and wait for normal operations.

Plug DVR back in and wait for normal operations.

Plug receivers back in and wait for normal operations.

What's the result?

I have tried all the above steps. I’m trying to figure if the problem is with the box or with my tv. 

Let us help you fix the random video sound loss on your U-verse service, EllbyMac!

I did all the steps baseball guy listed In. That. Order.

Seems to have done the job.

Thank You! 

With AT&T (and other TV services), lots of computers need to be in synchrony with each other. If one goes even slightly haywire, things can go wonky.

Restarting the tech is always a good first step...phones, laptops, tablets, tv.
