This is a Hot Plug issue. there are two fixes (one somewhat reliable and the other very reliable. Both force a Hot Plug reset.

#1 (somewhat reliable):
Instal an HDMI splitter between the STB and whatever is next in line.
Plug the splitter in an automated timer, turn it off every night and then back on in the AM.

#2: (very reliable):
Instal the Ethereal HDM-AIO2 between the STB and whatever is next in line.
Connect the HDM-AIO2 to a relay on your control system (if you do not have on use our CS-IRKITCCUS for this function [Link: metrahometheater.com]).
Every time you turn off the TV open the relay, when the TV is turned on close the relay.
