X1 TV Box Not Working. System Reboot Did Not Work.

My X1 TV box stopped working. Yes, I checked all the cables and plugs. Yes, I am using the correct HDMI input settings. Yes, I used the Xfinity mobile app to troubleshoot. Yes, I did a system reboot. The bot in the app did another system reboot. It didn't work. I just keep getting "No Signal" messages on the TV screen.

The bot in the chat program said it can no longer help me.

I want a service technician to come to my house and fix it, but I can't get through to a live human. I tried Messenger and sat in there for 35 minutes waiting for a response before giving up and closing the window.

So. Tell me. How do I get my TV box back online?

it is likely the HDMI port on your TV for the set top box is no longer communicating with the set top box. have you tried changing the TV input to another HDMI port that has signal then change back to the set top box? unplug the TV for 30 seconds and plug back in and turn on? does your set top box have a display (DVR) or power indicator LED's?

Thank you for responding.

have you tried changing the TV input to another HDMI port

Yes, that didn't fix the issue.

unplug the TV for 30 seconds and plug back in and turn on

tried that, no change.

does your set top box have a display (DVR) or power indicator LED's?

Hmm. I'm not sure what the difference is in what you are saying. There is a clock on the front and three spots that say Remote, Data, Record.

@LMHUSCG Thank you for contacting us about this concern. What our Expert @Rustyben mentioned are all part of our troubleshooting and common causes of the "no signal" error. 

 

 

  • An incorrect input selected on the TV (using the tv or remote to change)
  • The set-top box being offline
  • 3rd party equipment is offline or on wrong input (audio/video receiver, HDMI switch, dvd player, etc)
  • The video connections between the TV Box and the television are connected incorrectly

 

The next step is to check if you are able to perform the following: 

“exit>exit>exit>720”. (This sets resolution to 720) 

 

If you are still not receiving signal after this can you also retry restarting your TV again by unplugging the power supply 

and then returning it?

@XfinityEva

This did nothing.

I also unplugged, plugged back in; tried a different HDMI cable (also tried both HDMI ports and made sure the input was correct;) unscrewed the coaxial cable and screwed it back in ... I am still getting "No Signal."
