Uverse freezes and tv loses signal

When you lose service does it come back if change the channel up or down?
If yes, how long before going out again?

Do you also have ATT internet with tv service? 
If yes, does the internet quit working at the same time as the tv service?

We have uverse tv and internet does not come back until box has reset itself.  Internet stops because the modem resets when lose service.  Even with new modem

Why would this happen on all tvs?  It does not happen on just one and it is random.  Also just recently started happening in last several months and have had U-verse for over 3 years at this location without a problem.  

Hello @Kjur123,
Thanks for reaching out, let's shed some light on your concern and find out what's causing this!

Sometimes if your RCA cables are not properly installed and if it's not connected to their corresponding slots then it would result in loss of signal.

This happens also because of a communication issue between your receiver and the AT&T network.

We recommend that you try the following fixes below:

Restart your TV box provided by the cable company.
Use Wi-Fi range extenders to improve signal range and reduce AT&T internet connection drops.

We also recommended that you check out this article to have a better and complete understanding on U-Verse TV Down

We have had this service without any wiring changes for over 3 year without the issue we are having now.  ATT did replace modem still having issues.  We have changed so the the cords are now plugged directly into outlet no surge protector.  Will see if that makes a difference.   It’s just strange that it has started happening in the last 3 months but never before.  If this does not work will be having another tech out  

Have also tried resetting the dvr as instructed will now see if that helps.  Plugging cords directly into outlet did not so frustrating
