Last night, three shows scheduled to record at 9PM, did not, all three with the message "No Signal". Another show at 9:30 showed the same status, so I looked back through more of the recording history and found what appear to be random shows not being recorded with the "No Signal" error.
I've also noticed that the tuner seems to "go to sleep" after not being used for a while. For example, I'll turn on the TV in the morning and there's nothing there. Toggling the channel up or down "wakes" the tuner and programming appears.
We've been listening to Pandora lately, but not as far back as some of the shows that claim to have not been recorded because of no signal.
Is there a reason that the signal would randomly drop?
Is there an "uptime" monitor where I can see when the signal is up or down?
Should I change a setting such that the tuner never "sleeps?"
