Why has the amber LED on my X1 DVR been on recently while watching TV?

I did the opposite.  I turned on Power Saving, and the light went off.  I don't know if it's going to go on again in the morning.  We'll see.

Ever since Comcast has been doing work in my area, i.e., cable work of some sort. The Amber LED has been on my TV Box. Does this have something to do with the cable work being done outside?

This is not a permanent fix but if you are tired of looking at that amber light go to settings, device settings, device lights, power light brightness and select you don't have to change anything just exit and the lights go out until the next update if they would just add that sequence to their coding we wouldn't have to do that manually

The data light on my box was red but thanks to your suggestion about changing the brightness back to zero and then reset to level one did the trick for now. That light has been annoying me for two weeks! Thank you so much for your helpful post.
