tv tuner not working every few days since NXOE

Im having exactly the same issue

I just saw the same issue last night on my Xbox TV tuner, I tried different USB ports, and that didn't help.  What I noticed was that the TV Tuner itself, it usually has the light that stays on the whole time.  When you unplug it, then plug it back in, the light would come on...then turn off after a few seconds, which is why it wasn't picking up.  I thought the TV tuner was defective, as I was going to take it in to the Microsoft Store today and exchange it for another one.  

Exact same issue here!

- Black Screen in Live TV

- No Channel available in the guide, only HDMI.

- I can successfully scan for channels.

- TV Tuner adapter light remains off.

I live in Canada, for some reason after I added a space in the postal code it worked again....

I was having the same issue (in Canada).  I noticed the postal code needs a space to recognize when you set up as well.

I plugged my TV Tuner into my computer and it works fine for hours on end so I can confirm the hardware doesn't have an issue.  

It seems to be some sort of conflict with the external drive I have on my xbox one.  When I unplugged the external drive the TV tuner started working immediately.  When I plugged the external drive back in the TV tuner continued to work.  It may be a coincidence but something to try if you have other USB devices plugged in.  

Just been having the same issue not detected. Fixed if you in stall smartglass goto tv listing then choose a program and play, the xbox plays it then works fine. I use android version from phone. Not it doesn't say not detected...till next time :)

I'm having the same problem. I don't have anything else plugged into the USB and Smart Glass doesn't seem to work either. I've just bought the tuner and haven't got it to work once. Has Microsoft got any solutions for us?

Same thing here, stopped working all of a sudden the other day. It asks for a postal code to pick a provider which is now "not set up". There isn't a spot to add the post code??

Yep... same problem here in Australia. Every couple of days, seems that I have to reset all TV settings to get the channels back again. That seems to be the only way to fix this until Microsoft handle it in the next release?

Same issue here in the UK. every few days when i turn on the xbox it tells me the tuner is not detected (it is connected properly). A hard reset fixes the issue but its getting frustrating.
