how do I make the xbox one stop looking for a tv signal

Are you saying you are getting no picture on the TV when the Xbox is turned on?

If so, troubleshoot these things:

- Ensure your HDMI cable (between the Xbox and TV) is plugged into "TV out" on the Xbox.

- Check that you are on the correct HDMI input with your TV settings.

- Ensure the HDMI cable connection is secure in both the ports of the TV and Xbox.

- Try a different HDMI cable.

- Try a different television set.

I have the explorer 8642HD from Cisco. But did you try to see the signal strength on your illico box? I am telling you this makes a big difference if the signal is too low.

It would make sense to start with that. A low signal will not interfere too much on a TV but it seem to have a big impact on the Xbox one.

If you want give me the model number and I will look for you on how to check the signal strength

Don't confuse what the xbox one will send to signal to vs. what the TV is set to receive.

This is a TV issue based on what signals the TV can receive and how.

I have had the same issue on my sharp aquos. The issue seems to be related to xbox one controlling the signal to the tv when you allow one guide to power the tv off and on through hdmi signal. I deselected this and it has fixed the issue. This has to be
a signal coding issue with the xbox one. My ps4 and we work just fine turning the tv off and on and allowing video and sound. Hopefully xbox looks into this

Not sure I explained it clearly enough. My TV has 3 HDMI inputs, all of which can be configured for PC, Game Mode, TV etc etc. The Game Mode makes the XBOX input fill the screen and overall looks better than say in TV mode. So if the input from the XBOX
One is set to Game Mode, then I switched the XBOX One to throughput the TV signal, then I would be watching the preset HDMI in Game Mode even though I was watching a TV/Tivo channel, if that makes sense.

.

So to recap

.

My TV has one HDMI port set to TV input and another one set to Game Mode input, and I simply change the input depending on wether it is a game I want to play or a TV channel to watch.

.

But if one HDMI input is being used by both XBOX One and a TV signal input, then the TV's HDMI port setting will only default to the one I set it to in the first place

.

So it is the TV that determines what display I will get regardless of what signal the XBOX One sends.

If that doesn't confuse you then nothing will, already getting a headache just re-reading it
