@Ashley23 @Kilimanjaro1 Here are some troubleshooting steps you can start with. If you need further assistance after going through these, feel free to send us a provate message by clicking here. Provide your name, 9 digit U-verse account number, and phone number. We may need more information to be able to take any action within our systems.

 

 

If you are having issues with:

  • Receiver resets
  • Loss of recordings
  • Pixilation
  • Freezing
  • Or any of these error messages above, check out our steps below to resolve your U-verse TV service:

Rebooting the receiver is the quickest way to resolve most service issues:

  • Press and hold the power button(located on the left side of the receiver) for 10 seconds.
  • Another way this can be done is unplug the power cord from the wall outlet, then plug it back in after 10 seconds.

 

 

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:

  • Receiver resets
  • Loss of recordings
  • Pixilation
  • Freezing

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:

  1. Unplug the receiver or DVR power cord from the wall or back of the box.
  2. Wait 10 seconds.
  3. Plug in the receiver and DVR.
  4. When three white dots appear on the screen, unplug the receiver/DVR again.
  5. Repeat this process two more times.
  6. Plug the receiver/DVR back in on the third time and leave in. Three white dots appear followed by a gear with a status bar at the bottom of the screen. If the Recovery screen does not appear, repeat the steps above.

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

                                                                                                 

  1. Using the above image as guidance, hold down the Down arrow key + OK key +Power key outlined in red at the same time to power down the DVR.
  2. Continue pressing these keys until a gear appears on the screen and release the Down arrow + OK keys.
  3. If the gear on the TV screen appears, wait until completion.
  4. If the gear on the TV screen does not appear, repeat the disaster recovery process.

 

If the previous steps have been exhausted and the TV receiver continues to malfunction, please send a private message with your account number and contact details to ATTU-verseCare for further assistance. If you are not a member of the U-verse community forums, we welcome you to register and reach out to us.

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.Smiley Wink

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.Smiley Happy

 

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.

Look at the back of the uverse box for type of wire running to tv input.
Look at back of tv for input number.
Match input with remote to physical connection.

Types of connection
Coax .... input (source) to tv, tv needs to be on channel 3
Red, White, Yellow....input AV (1-?) Old vcr type connection most tvs will have at least two, AV1, AV2
5 way component, red, white for audio, red, green, blue for picture...input shpuld be componet (1-?)
HDMI....thin rectangle set input to HDMI(1-?) Depending on which plugged into.

Hope this helps, older tv probably coax or AV, newer tv likely set up component or hdmi.

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.

Cofins4Terorists - It is not mysterious. It is exactly what it says - The STB does not detect a signal. It does usually come back in a few minutes, so that should be the first suggestion - wait.

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?

SRH021 - It does sound like the DVR has gone bad - You have service with a different STB on the same connection??

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!

No it isn't, the coax you're basing the answer on connects different units, not from the TV to the DVR/STB.  In any case the coax was replaced by cat5e cabling, the only thing Uverse techs use nowadays. Smiley Wink

I had the same problem.  If you are using HDMI connections some tv's have a handshaking issue with the tv.  That was the problem with my Samsung. It would work for a while and then all of a sudden drop the connection.  I got tired of it and switched to component and have not had a problem since.  You get the same hi def picture with component that you get with HDMI.

Some users have had to use the 4th of 4 HDMI inputs to get Uverse to work properly.  With this 1225 I have now, I can use HDMI, the 2250 I had b4 had the black crush problem on HDMI.

 

I could see the difference between HDMI and component here on my Panasonic plasma.  Component gave a slightly 'softer' look to the image, but was fine for full-time use of it w/the 2250.

 

W/the 1225 I've had for about 2 months or so, I've gotten the 1005 HDMI error 1 time and an off/on of TV and 1225 fixed it.

 

The 1216 I had originally got HDMI errors only 2 or 3 times in 5 years of use.  2 or 3 times I had the HDMI just fail and give me 'snow' on the TV.  That required a reboot of the DVR to get it back.  During all of these the component connection worked fine. Smiley Wink

I have a main box and 3 boxes in my bedrooms, the three boxes went off, they all said no signal so I called and had an ATT rep walk me through the process. He said I needed new dvr's so they sent them to me and I hooked them up the same way and they are doing the same thing. I turn on the box/tv and it comes up saying to push the menu button on the receiver then push the wps button on the main box and wait for them to pair but they dont pair up they keep going back through the same process. I really need a tech to come to my house and help resolve this issue.

Seems like you need to change the input on the TVs if getting the no signal message.  What they told you will do nothing as you've found out.

 

Press the TV button at the top, then press TV/Video until Uverse shows up.  Then press the ATT button at the top to get Uverse control back. Smiley Wink

I have basically the same problem as ratbear.  My second TV also shows no signal.  After plugging and unplugging everything in sight, I finally got a screen that said to press the WPS on the access point for 10 sec., then press the OK button on the receiver.  After a bit a screen came on that said Connection Success (or something similar), it went off then the No Signal screen came on again, then the blue ATT Uverse screen with whirling circle came on and has been on now for about 15 min. now.  Any help would be appreciated.

I had this problem too. The other TV's were working fine, but the main TV was not. I did a hard reboot and nothing I kept getting "NO Signal" All the wires were good. THe TV had been set to HDMI3 before, so I just clicked to HDMI2 and the TV came on instantly. I dont know how I got switched from HDMI3 to HDMI2 but that might help somebody to just try a different HDMI.

@Ashley23 @Kilimanjaro1 Here are some troubleshooting steps you can start with. If you need further assistance after going through these, feel free to send us a provate message by clicking here. Provide your name, 9 digit U-verse account number, and phone number. We may need more information to be able to take any action within our systems.

 

 

If you are having issues with:

  • Receiver resets
  • Loss of recordings
  • Pixilation
  • Freezing
  • Or any of these error messages above, check out our steps below to resolve your U-verse TV service:

Rebooting the receiver is the quickest way to resolve most service issues:

  • Press and hold the power button(located on the left side of the receiver) for 10 seconds.
  • Another way this can be done is unplug the power cord from the wall outlet, then plug it back in after 10 seconds.

 

 

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:

  • Receiver resets
  • Loss of recordings
  • Pixilation
  • Freezing

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:

  1. Unplug the receiver or DVR power cord from the wall or back of the box.
  2. Wait 10 seconds.
  3. Plug in the receiver and DVR.
  4. When three white dots appear on the screen, unplug the receiver/DVR again.
  5. Repeat this process two more times.
  6. Plug the receiver/DVR back in on the third time and leave in. Three white dots appear followed by a gear with a status bar at the bottom of the screen. If the Recovery screen does not appear, repeat the steps above.

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

                                                                                                 

  1. Using the above image as guidance, hold down the Down arrow key + OK key +Power key outlined in red at the same time to power down the DVR.
  2. Continue pressing these keys until a gear appears on the screen and release the Down arrow + OK keys.
  3. If the gear on the TV screen appears, wait until completion.
  4. If the gear on the TV screen does not appear, repeat the disaster recovery process.

 

If the previous steps have been exhausted and the TV receiver continues to malfunction, please send a private message with your account number and contact details to ATTU-verseCare for further assistance. If you are not a member of the U-verse community forums, we welcome you to register and reach out to us.

I've tried all of these for 2 days - no luck.  Is there someone that can do this by remote?
