Hmm, I've certainly never had that happen to me, but then again I do 
turn my lcd's off occasionally. if you google for lcd burnin you will 
find several pages that say lcd's don't have burnin. What's happening to 
you would probably not be considered burnin, maybe ghosting? But lcd's 
do have lamps that eventually burn out and need replacing, so it is 
advisable to turn off your tv when you're not using it to save on bulb 
replacement.

You can't burnin an lcd by having the same image on it for 2 hours a day 
and then leaving it off for a couple hours though, like you can with 
crts, which is what he is afraid of I think.
