I have a 43" Plasma TV, and was wanting to mount it on the wall above my fire place. I was reading online, that the ambient heat of the fire place may cause damage to the unit, but only if the TV was on. Therefore, if the TV is off and I have a fire going, I have nothing to worry about... or so I read! However, when I am home, the TV is usually turned on. So in the winter, I can either watch TV or I can have a fire going! heheh I wonder which I would pick! Anyway... I was just curious if anyone else has this set up? If so, have you encountered any problems?
