Xbox One is on but not responding, no signal to TV.

Hi, thanks for responding

-It is a regular Xbox One S

-There are no other external devices plugged into my device

-Yes, it says "No signal" on my TV when I turn the Xbox on

-Due to the way my TV is postioned. I am unable to fully removed my HDMI and use another HDMI cable or a different port on my TV

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.

OK, so more testing tonight

1) I went through every Remote Code I found on Vizio's website, both four and five digit codes. Within each code, I made sure to try both On/Off and Toggle signals if they were available. No dice. Receiver responds, TV does not.

2) I connected the Xbox One directly to the TV via HDMI cable to eliminate the receiver as part of the issue. When I went to add the TV for control, the Xbox said it auto-detected the TV and knew how to control it. Great! Except it didn't. Even directly
plugged together, the Xbox cannot control the TV. Interestingly, the Xbox selected Universal Remote Code T1758 when it was plugged directly into the TV.

3) HUGE. I brought down a different TV and connected it to the Xbox. It auto-detected and selected Universal Remote Code T2049. That worked! The Xbox was able to control the TV as expected. I even re-routed the cables so the receiver was "in the way" and
the Xbox One controlled both correctly.

So, that seems to have narrowed the issue down to some sort of bad interaction between the Xbox One and the Vizio TV. More troubleshooting...

4) I did a factory reset and totally recalibrated the Vizio TV. It still did not respond to the Xbox One. It DOES respond totally normally to its own native controller app (via WiFi) and it responds normally to IR signals from my universal Logitech remote.

I have no idea what to try next. Going to start digging into Vizio TV issues, I suppose. I don't know why the Xbox suddenly quit controlling two devices but is now back to being able to control one of them but not the other.

I should mention that I still think the Xbox has something to do with this because the receiver will intermittently fail to respond to a power toggle sent from the console. I did a lot of testing with the Logitech remote that I've got and it sends signals
to the TV just fine. I also used the WiFi remote that came with the TV and it also responds just fine.

Something about the communication coming from the Xbox to the Vizio TV is borked.

Please note at this time I have also already tried a "soft factory reset" and then re-inputting the TV code noted above. It still works the receiver (with the occasional fault) but it will NOT power the TV on or off.

I have similar issue that HDMI connected between XBOX and TV but no signal in the TV, the issue is i have no idea what cause the issue ? as the cable since long time in the place that no one touch it, but one day i run the xbox but tv not responded with no signal i changed the cable to other original cable and no changes.

I hope someone face same issue and can help me with good feedback and way to fix the issue.

Also in my city Dammam-Saudi Arabia we don't have any Microsoft services center to send the console

hope someone can help me in this it's been three months on this issue

I held the power button, shutting down the Xbox One.

Turned on the 360, turned on the Xbox One and said snap TV.

It said no signal, so I told it to watch TV [fullscreen] and it still said no signal.
