I have a 37-in LCD that I use with various sources. There are times, like when listening to a podcast, monitoring a download, etc, when I don't need the TV turned on constantly but just need to monitor occasionally. Or a I might just want to listen to a music channel via my cable service.
During such times, is it better to frequently turn the TV on and off, or should I leave it on for the duration? To give a specific example, yesterday I turned it off and on 7 or 8 times over the course of just over an hour.
I'd like to leave power consumption aside for this question and just focus on the TV's longevity.
