HDTVs and the heat generated from them

hey yall, i need a bit of advise on hdtvs. here’s the deal:

i bought a 42" Vizio using 1080p with my ps3 and boy did it turn my room into a desert! it was so hot after about 1 hour of gameplay. after about a month, i got fed up with it and returned it. just fyi, i was using this tv in my bedroom.

anyhow, i’m looking for an hdtv that doesn’t give off so much heat. something between 32"-42" and at least 720p. any suggestions as to what i should get?

please help. thanks in advance.
