The aging method of both lcd and plasma is the reduction of light producing capability so running the backlights higher or your plasma brighter will in theory reduce the life of the display.
Plasma tv heats up room.
Actually all light energy from the plasma or any light bulb turns to heat.
So a 500w plasma will heat the room exactly the same as a 500w.
Having a ceiling fan isn t going to do a whole lot.
Depends which model you re going for.
Remember in order for the hot air to leave the room an equal amount of cooler air must enter the room.
Still a bit less heat than on a pana plasma though.
You need to put the heat somewhere else if you don t want it in your room.
As it turns out my tv uses less than 20w a figure i found pretty quickly by looking up my model on the manufacturer s.
That s a big tv and i m sure its drawing at least a few hundred watts of power.
Plasma tvs generate more heat and use more energy than lcd tvs due to the need to light phosphors to create images.
Yeah i dont own a single plasma but my 55in toshiba lcd gets pretty hot.
So its basically a psuedo space heater.
The problem is that the heat is not leaving the room.
So you need to increase the ventilation through the room.
In the winter i don t even need to put the heat on because my tv makes my bedroom warm enough on it s own.
However i suspect most of the sets won t last that long anyway with faults scrapping the sets before screen aging makes them unuseable.
However this problem diminished over the years due to pixel orbiting and related technologies.
Plasma tvs are more vulnerable to burn in of static images.
The plasmas where i work at do generate a fair amount of heat but nothing out of the ordinary.
It warms the dust in the air and walls of the room.
Essentially all of that power its drawing is going to eventually turn into heat in your room.
I have a 42 panasonic viera plasma tv.
Plasma tvs ranging from 42 65 inches use 90w 214w when powered on.
This is actually a common problem in equipment and computer rooms.
Now if you compare a 32 inch lcd tv that uses 50 watts when powered on to that of a 100 watt light bulb you d need two tvs to equal the bulb s output.
