Xfinity box won’t turn on

Hello,

I am having an issue with my box not turning when I power on the tv with my X1 remote. The box seems to be in sleep mode and the “Power” button on the Xfinity remote will not wake it up out of sleep mode. I do not have the power save option turned on. The only way to turn on/wake up my box when it won’t respond is to physically unplug it from the back and then plug it back in. The light on the front of the box never turns off, even when it won’t respond (not sure if this means anything). This is my second box with Comcast because of this issue and it will not fix it. Any help is appreciated. I have a Toshiba TV.

All my X1 boxes have a power on/off switch.  If they do not have a light on the box, I use the power button to turn on the box.  Check the power save setup and let us know what it says.

Re: Xfinity box won’t turn on

Hi,

I do not have a Power button on my box. When I press the “power button” on Xfinity remote the TV goes on, but I get a black screen (the white light on my box is on however). Because I don’t get a “no signal” screen but instead just a black screen, it leads me to believe the box is just not responding? Power saver is off in Xfinity settings and always has been.

This forum (and there are many more out there explain my issue) looks like Comcast hasn’t found a solution: https://forums.xfinity.com/t5/TV-Archive/Xfinity-XG1v4-Black-Screen-Lock-Up/td-p/3049524

Which X1 box do you have?

XG1v4-A

Re: Xfinity box won’t turn on

it appears that my xg1v4 at random times? or aftr an update to the XRE or firmware version is not loading settings that turn off power save function so the box goes into power save that shuts off the video HDMI link with the TV. I, too, thought the box was 'off' but found if i change input on my TV (that the set top box is connected) to another live HDMI port and then right back to DVR the video and sound is restored and the buffer for the channel the set top box is on is intact (can scroll back in the buffer an hour). I had an xg1v3 previously.

Re: Xfinity box won’t turn on

Hello, Redbird_2016!

I'd like to help with this issue. It looks like you have gotten some great feedback thus far. @Rustyben made a great suggestion, can you try just changing the input on your tv back and forth the next time you experience this issue and see if that helps? It may not stop the issue altogether, but it may be an easier fix than having to get up and unplug the box until we are able to find a more permanent solution. I look forward to your next update.

Hello,

Thanks for the suggestion. Unfortunately the issue happened again this morning and switching between different live inputs did not resolve the problem. I had to revert back to unplugging my box.

did you check to be sure power save function is 'off' and did you change to an active device/HDMI port and after video displays then changing back to the DVR?

Re: Xfinity box won’t turn on

Yes I did, still no luck. Any other suggestions? Other forums are appearing with the same issue and no one can seems to fix it.

Can you post the details of how your TV and X1 box are connected to each other?

Co-Ax from wall to box and then an HMDI from box to tv.

Re: Xfinity box won’t turn on

I'm having exactly the problem that OP describes.

 

XG1-v4 box. Nothing at all exciting about my setup - Coax into the cable box, HDMI into the TV.

 

I've tried switching inputs doesn't do a thing.

 

Does replacing the box help? This is super frustrating. Unplugging the stupid thing and plugging it back in works, but that takes ~5 minutes, and interrupts service to the rest of the house as well.

Re: Xfinity box won’t turn on

I have the same issue. Tried the following so far and still having the same issue:

1. Unplugged and plugged back in. Box reboots. Works. However if left for a few hours/overnight, it apparently goes into a sleep mode and doesnt “wake up.” I too do not have a power button.

2. A quicker way to reset the box is to restart via the My Account app. However, we should not have to do this every time to use the service

3. Got Xfinity to come and swap out my box. Next day, same issue.

you may have the one LED on front XG1v4 4K/UHD set to box DVR. Comcast said they are working on a fix for the issue. I just change TV input to roku or chromecast then back to the DVR and the TV wakes up the video connection (buffer of current channel still available).
