Why does my Xbox One shut off when I plug my HDMI Cable in

"Hdmi cord shuts system off when plugged in "

"A month later my other xbox does the same thing plug the hdmi in and shuts off"

The console should be completely powered off when setting up or connecting the HDMI cable.

Once physical setup is complete, Turn on the TV, AVR if using, then turn on console last of all.

Don't connect or disconnect cables while the console is on. You could spike the console with static and the console will need repairing.

UPDATE WITH RESOLUTION!!!!

In my frustration I gave up troubleshooting after everything I had done and began typing this question. My wife wanted to attempt to fix it so she watched a YouTube video instructing her on how to completely power off the Xbox by holding the power button. Once it was shut down, She checked the back of the Xbox. To preface this:

I had the Xbox plugged into the TV with an HDMI cable and plugged into the wall with the power cable. There was a different HDMI cable that i had used for testing laying next to the Xbox that was connected to the TV as well. My Wife unplugged the HDMI cable from the "To TV" Port and plugged that same cable into the other HDMI port on the Xbox. She then plugged the other HDMI cable that was laying next to it into the Xbox's main HDMI port (To clarify there are now two HDMI cables plugged into the Xbox). Then she unplugged the power cable (with the Xbox already off completely), plugged it back in, and powered on the console. When it powered on it was magically working fine again, and continued to work fine when I unplugged the secondary HDMI cable from the port that leads to a cable service. I had already tested this theory with both cables and multiple ports, and the only thing she did that i had not tried was plugging an HDMI cable into that second HDMI port. My only thought is that something was stuck software wise on the HDMI chip and "activating" that second port kicked it back in. I have a degree in IT with 3+ years of job experience and I have no clue what could have caused that, but if any Xbox Technicians see this post I would be very interested to here any possible ideas as to what would have caused it.

I'm with the same problem. For me, when i plug the hdmi input from my xbox on my cable TV set-top, the tv works, but in a green image (i can see the image in different green tones, audio works).

But plug my cable TV set-top directly to tv (same cable, same hdmi port), it works fine, i don't have this issue.

If i plug my computer instead tv on xbox hdmi input, (same cable), works fine too!

So, my hdmi cable seems works fine, my cable tv set-top seems works fine, my hdmi cable seems works fine, the hdmi input port from xbox seems works fine, but this specific configuration, de cable tv device plugged on xbox, does not work!!!

Ok i tried you idea and it works. when i had the color cable it did not turn off on me but when i went to put back on the HDMI cable it would turn off on me. why do you think it does that and how can i fix this issue so i can keep using my HDMI (it does
not look good with the color cables lol)
