LCD/Plasma over fireplace

Archived from groups: alt.tv.tech.hdtv (More info?)

It will probably affect the display of the plasma, the LCD may be unaffected
but it probably may shorten the lifetime of the lamp due to the added
ambient heat. It seems that he actual temperature of the plasma generated
within the cells can be affected as a result of lower than or higher than
average ambient surroundings. Also by drafts created by the thermal
differences at the particular location you are proposing. Check with the AV
forums or manufacturers regarding these effects. IMHO I would also be
concerned about the effect of any combustion by-products on the sets.

Yes, it's a really bad idea..
Heat kills electronics in many different ways..

Increases the probably of electrolytic caps failure..
It reduces the ability of critical components to dissipate heat
build up.
It adds to mechanical thermal stresses. Materials expand and
contract at different rates. The more heat, the greater the stress.
Enough high stress cycles and things start to crack and break.
Virtually all materials degrade faster at higher temps.

Lastly, it will probably void your warrantee.. Since you'll be
operating and/or storing the TV outside its rated environmental
specs.

Consider any flat panel TV as a fragile precision instrument...
treat it well, and keep it cool location.

You may be better off rearranging your room layout. However, unless
you want a smaller set or to use the TV as a computer display for gaming
& surfing, the plasma will provide the better picture.

No way I'd consider a Plasma there, not likely an LCD, and I'd really
try to avoid anththing above the fireplace.

On the other hand, I'm very familiar iwth unvented gas fireplaces and
have no issue with them. The problem is that heat is the worst enemy
you can imagine for flat panels in particular. Really bad idea.

I wouldn't even put a painting there, especially if it's hot.
Everybody knows that there are only two legitimate things to put there:
either a crossed pair of flintlock rifles, or your mother's ashes.

"Unvented fireplaces are very common in loft conversions in Chicago. It

burns gas, it's not really any different to a HVAC unit. "

Sorry to burst your bubble, but an unvented fireplace is very different
from a gas furnace HVAC unit. Every gas furnace is vented to the
outside, while an unvented fireplace sends all the combustion
byproducts into the living space, instead of outside. Normally, these
combustion byproducts are not enough to cause health problems if the
fireplace is run occasionally, which is why they are allowed. However
they do contribute some small amounts of unwanted and unhealthy gases
which could be a problem for those with breathing difficulty. Also, if
the fireplace malfunctions, it can emit dangerous levels of carbon
monoxide.
