My cable tv service is not listed.

So I assume you will also be boycotting cable TV service, magazines, public transportation, airports, US highways, the Internet as a whole, and the US postal service? (just to name a very small list).

I;m happy to report that I upgraded my tv service, which included a new cable box and now my live TV feature works! The only problem is that the channel list is out of dated but I would guess it is some type of regional issue. So I'm happy it's finally
working correctly.

There are a few things to help identify where the issue is, some might not work if you don't have the equipment, but it'll help find out where the problem actually is:

Start with the cable:

• Try a different cable with same device and same port on TV
  
• Try that same cable to a different device, see if it displays
  

Check port on TV:

• Check that cable into a different port on the TV
  
• Make sure the input and the port match for the TV
  

Check the TV:

• Can other devices connect and display on that port/input
  

Check the device:

• Does the device display on other displays? With different cables?
  

Just to be clear about the question. You are saying Cablevision is your actual cable service provider and the division or affiliate of the company providing your local Cable TV service is Service Electric correct? Also that your cable box does have an HDMI
out.

Let me answer the most important part first.

1) If it has an HDMI out then yes it will work with the Xbox One which supports both SD and HD resolutions coming from a cable box. So you will be able to watch TV on the Xbox One unless there is something very unusual about your cable box.

2) The Xbox OneGuide which has been demonstrated in recent press releases allows you to navigate TV Listings and change channels among other things for many US Cable TV Providers.

Hello @[TrapCrystal]! I hope that you are doing well!

Thank you for bringing this inquiry to our forums community. A no signal message on your television may indicate that the HDMI may be the cause of the problem. We suggest first to check the following:

• Confirm that both your TV and Xbox console are turned on.
  
• Check that your TV is set to the correct input signal (HDMI).
  
• Check that the HDMI cable connections to your console and to your TV are secure.
  
• Check that the HDMI cable is connected to the "out to TV" port on the console.
  
• Try plugging the HDMI cable into a different HDMI port on your TV.
  
• Try using a different HDMI cable to connect your console to your TV.
  
• Try connecting your console to a different TV.
  
• Power cycle your Xbox : Press and hold the Xbox button for 10 seconds to turn off the console, and then turn it on again.
  

Please give this troubleshooting a try and see if the issue is fixed just to make sure that it's not a hardware issue. However, if the issue persists, it can be a hardware therefore the console needs to be serviced.
