TV's don't have the same issues as computers, because they typically
have no plug-in cards. I think it's been tried, largely
unsuccessfully, in the past.

Turn it off if you are not watching or listening to it for more than
30-60 minutes, I'd say.



The plug in cards don't have anything to do with it, the argument is mostly
for mechanical components like hard drives and fans. I think it largely
stems from the fact that a drive with marginal bearings or some other
problem is most likely to fail to start up from cold a while before it fails
while warm and running. Same with light bulbs that most often fail at
turnon, but while people will argue both ways, I'm convinced that reasonable
power cycles will have no effect on the life of a piece of equipment. Don't
flip it rapidly off and on, but if you walk away for more than a few minutes
shut it off.
