That is because older early model plasma TVs were like toaster ovens. I was
at a trade show, where we had to wait for the next demonstration in a long
hallway that was lined on both sides with plasma TVs when they first came
out. It was like the inside of an oven, you could feel the radiant heat from
the screen on your skin much like a tropical sun burning your skin. They
have improved them greatly now, the heat from the screens is minimal.
My LG 47" LCD runs 241 watts according to their web site. I also found they
no longer list the consumption on TV aside from standby that is 0.3 watts.
So, I checked Samsung to see what they offered. They just state it exceeds

Code limits how close a wood fireplace mantel can be to the fireplace
opening based on the size of the opening and the projection of the
mantel into the room. Assuming that there is a mantel, it does meet
Code, and it doesn't catch on fire frequently, if you are that
concerned about melting plastic on the TV, above the mantel, I'd be
more concerned about getting out of the house because it's on fire.
Check it out - throw a thermometer on top of your mantel and fire up
the fireplace. Get it good and hot. You'll see that your imagination
is running away with you.
Fireplaces throw heat out more than they do straight up, and the
people in that room would be sitting in their underwear sweating
bullets before the thermometer registered 100 F. In other words, a
hot summer day without AC.
I was surprised by the number of posters who commented on the viewing
angle being a pain in the neck, and I suppose it would be if the
furniture and/or person's typical viewing position is erect. When I'm
watching TV I'm usually on my way to horizontal. I have my feet up on
the coffee table and my neck is supported by the back of the couch.
When I'm sitting like that when I look straight ahead I'm looking dead
center of the screen.
A lot of people with the TVs above the fireplace get those double
recliner couches, and that's just about the most comfortable way to
watch TV there is. You can't watch a low down TV comfortably in one
of those recliners, least I can't, as the angle now makes me crane my
head forward, and that does bother my neck. And the higher the TV
(within reason), the more people can more easily see the TV, which may
or may not be an issue for some people.
But don't take my word for it, use one of the online viewing angle
calculators, or check out an AV forum, such as:
As far as the soot that people mentioned, again, if you have a mantel
then it's not really a concern. I've never seen soot that curled up
and around and back to the wall above a fireplace. If you're having
that much soot, or really any appreciable soot at all, then there are
issues with the chimney's draw and/or the size of the fire that is
being built, and those should be remedied as they are potentially
serious problems whereas a TV's location is not.
That is half true. If the ambient temperature is higher than the specs
listed for the TV you will put a strain on the unit, and void any
warranty. Most all electronic appliances, like a TV, have a low and
high ambient temperature in their specs. If you exceed that temperature
you put a strain on the electronics because the heat sink won't do its job.
Ambient temperature matters. I just grabbed the first manual I could
find in the manual folder and it's for a DVD player. Specs. say the
ambient temperature range is 41ºF to 95ºF. The temp above a fireplace
can surely go over 95ºF.
Void any warranty...? Huh? Is there some sort of temperature sensor
in a TV with the ability to record the temperature? If you live in a
hot climate, are all warranties void? That makes no sense.
As far as the strain, I've had roaring fires and ambient temperatures
over 100 F and there's no picture breakup or anything like that
(frankly, not even sure how a high temperature would affect a TV - not
really sure what would happen). I'm not arguing that the TV is immune
to temperature, just that the people would be affected more than the
And we're talking about TVs, not DVD players, right? Here's what I
pulled off of Panasonic's site:
For a 50" Plasma TV
Operating Temperature 32°F - 104°F (0°C - 40°C)
For a 42" LCD TV
No operating temperature listed
Interesting yes. I'm not sure what point you are trying to make? It
appears you are saying to ignore the factory operating temperature
specs? Well hell yes, we can all go over the factory specs on most
everything we own without immediate damage. The manufactures don't
advise it, I don't advise it, you seem to believe that it doesn't
matter. Whatever. It's your choice.
No, Tony, I am saying that people are imaging there will be a heat
issue affecting the TV over the fireplace in some noticeable way, the
same way that they are imaging that the viewing angle is always
uncomfortable with it up there.
I have never heard of a heat issue with a TV above the fireplace, have
you? Here's a thread of three years duration, and there's no mention
of actual heat related problems, only WAGs that there would be a
It's interesting (I know, I find a lot of things interesting!) that
that thread started off almost the exact same way as this one, with
the same concerns and assumptions, and nowhere in there is a mention
of heat-related damage to the TV. There are many other threads with
essentially the same information, but I chose that one to post as it
was over a long time frame and addressed the same questions that were
brought up here.
I would not hang a TV over a wood stove, a vent-free gas fireplace or
over a fireplace that did not have a projecting mantel, or if the
fireplace is more or less constantly on in the winter. The surest way
to determine if it is safe enough for the new TV is to test the
ambient temperature above the fireplace with a thermometer while a
roaring fire is going. Anything else is guessing.
