@Ashley23 @Kilimanjaro1 Here are some troubleshooting steps you can start with.
If you are having issues with:
Rebooting the receiver is the quickest way to resolve most service issues:
We recommend plugging our devices directly into the wall. If you must use a power strip, use the surge protectors that are designed for high powered electronics. Not doing this may result in:
Make sure all connections (wall to receiver, receiver to TV) are placed firmly into the device. If the cables going from the wall to the equipment are damaged, feel free to contact us here.
To avoid loosing your saved programs, perform the Non-Disaster Recovery for DVR/Receivers:
If you are still experiencing issues with you DVR after that, perform a Disaster Recovery on the device.
Disaster Recovery for DVR/Receivers:
WARNING!: Disaster Recovery steps will cause your DVR to lose all pre-existing data such as: Recordings, Parental control settings, Aspect ratio settings

Is it on the right channel/input (video/TV)? If that's correct, I'd do a hard reboot by unplug/plug in power after 30 seconds. This will fix many DVR problems, let us know if it worked, good luck.;)

Hello dbennett, (No Signal) is common when your TV is on the wrong input as mibrnsurg suggested. Also, check the connection between the U-verse receiver and the TV. If a cable was accidentally pulled, it will result in No signal. If you are using a Coax cable between your TV and the U-verse receiver, you may just need to change the channel up or down to restore your picture. I have sent you a private message to provide you further options to resolve this issue in case you are still having trouble.
Use this guide to determine what connection is being used so you can make your input selection on your TV to match the U-verse receiver.

Happened to me tonight right at very end of a show so of course I missed ending. Phone and Internet were fine, was just the TV.
Did the check other channels as it says to do, did not reset modem due to other connections as stated above were working fine.
Affected ALL 4 TVs in house and ALL channels. So was planning to call service when after 6.5 minutes it came back on as if nothing happened.
What causes this?
What causes that stupid Blue screen with the click OK to watch pop up in middle of a show?
I'm afraid there isn't a person at AT&T that will tell us the truth of the blue screen.

If the broadband light on the RG goes red it is the RG or upstream. Call for remote test to see if it can be repaired or you need a new RG.
If you have COAX to feed the TV, it could be anywhere in the COAX system. Make sure you have compression fittings & the connections are tight. And, no barrel connectors After that you would have to disconnect legs to see if you can find one faulty one

I'm having this same problem. It's only with the main DVR receiver though. Happened right in the middle of viewing. Checked all connections. Disconnected the DVR, connected a regular receiver - TV/ connections working great. Re-connected DVR - just get the ATT start up (blue) screen cycling, then the "Press OK to Watch On Demand", then it cycles back to the ATT blue screen. All other TV (which are also HDMI connected) with regular receivers working. Could this be a bad DVR receiver?

If you try DVR directly connected to a working RG with a short cat5 & it does not work. it must be the DVR. You can try a destructive reboot at that point to see if you can revive it. You will lose your recordings with the reboot - same as with a new DVR. At least you save the wait for a new box.
Do this on the front panel of the DVR itself, not on the remote:
1. Press and hold down the power button.
2. Within 1 second, also press and hold down the OK and down arrow buttons.
3. All 3 front panel lights (red, green, blue will come on). At this point, release the power button, but continue holding down OK and down arrow.
4. When you see a gear appear on the screen, release OK and down arrow.
The system will reload the factory software from the network. This will take 20-30 minutes, and then the system will reboot.

I was having this same issue, we had signed up 6 days ago, it took AT&T 5 whole days to even consider the issue after numerous calls and hours spent on the phone with them. It was always "Checked the line, no issue found. Ticket closed." Finally we got a GOOD tech, he checked the coax cables and found out our lines were failing. He replaced all of our coax cable with cat5 cables. No issues for the past 24 hours!
