The light on my X1 box keeps flashing. What does this mean?




Below you will find a list of our X1 boxes and what the lights mean.

Xi3, Xi4, XiD and XG2 TV Boxes

Device Status Power Light

The "Loading/Rebooting"  status on our Xi3, Xi4, XiD and XG2 devices usually occurs after an update. To view more information about our X1 lights see here:



If you believe it may be an issue with your device, we recommend cleaning the device, ensuring it is in a well-ventilated area and rebooting the device (unplugging it from the wall outlet, wait 1 minute and then plug it back in). If you continue to experience this after rebooting the device and it occurs outside your Daily Update Time window you could also be experiencing low signal to your box or a defective device. You can test the outlet by connecting a different box there. If the issue persists with another box, you are likely in need of a technician visit. If you do not experience this issue with your other box, you likely need to replace the defective device. You can replace it by taking it to a local Xfinity store (find your local store here: or we can help you replace it by posting your request here:
