Just got the Samsung 55" 7100 series and have the 8000 series in our bedroom up stairs. For the past couple of days when I go down stairs in the morning I notice that the 7100 is on by the Samsung light being lit, it's also in standby mode as the red light is glowing. We have DirecTV and I'm thinking that maybe the remote from the up stairs TV is turning on the 7100 down stairs. I don't have a clue.
What do you guys think could the problem? I'll investigate it further when I get home later today.
I just noticed this on my Samsung F7100 as well. Seems to occur @ ~6:45PM each day. The screen never actually turns on, but the TV set itself does, which causes my Denon receiver to turn on too. My Monster power strip turns on my Denon when the TV turns on.
Perhaps it's some type of firmware auto-update feature?
