Leave it like that for some time, approximately five minutes, and then turn it on again. Try it and see whether the Xfinity Cable Box is still blinking green. If it is, move to the next solution.
Are the cables and connectors connected firmly and properly?

After you check all the cables and connectors the green blinking light should be fixed. If by any chance, it is still blinking, try the following step.

Is your remote malfunctioning?
