JVC 32 inch LCD Heat

My new JVC 32 inch LCD LT-32E478
appears to be running hot - ie there is
noticable heat from the top vents.
(rated Power Consumtion 159W)

There is a Menu Picture option named
"Energy Saver Mode" that "adjusts the
level of back light brightness" - values
between -30 and +30 (default +20)

I put an accurate thermometer on the
top vents and with a room temperature
of 75F-24C the vent temperature was
101F-38C with "Energy Saver Mode" at
-30; 108F-42C at value 0 and 117F-47F
at value +30.

Should i be concerned that these values
are too high - implying a shortened life
span- since a friends same model has
no noticable heat at the top vents?

Am i naive in hoping that a $1000 TV
might last ten years since it replaced
a 1988 CRT model that produced as
much heat but lasted almost 20 years?

Yes, these sets will generate heat when in operation, and depending on the
ambient temperature, seem to produce an exoborant amount. The operations
manual should indicate operational temperature ranges, JVC customer
relations should be able to determine if the product is within appropiate
terms when given your data.
BTW, you fail to explain if the set is wall mounted, placed on it's standard
table stand, or confined within an entertainment cabinet. As with any
display device, the product should not be within a confined place, at least
8.5cm on each edge, minimum 10cm on top, and 10-20 cm space behind.

My first set was or seemed too hot, except no hotter than what two 90W
bulbs running together 180W, though. But due to problems a
replacement set was indicated. This second set is cooler, judging
from the back vents (and stepping up to it without a shirt - I can
feel heat being radiated from the the large pannel). But things are
different now with my entertainment center. Whereas before, I'd
shelved the LCD beneath, to lower the LCD somewhat below a horizontal
plane of sight viewed from a couch, comfortable and ideal. That's no
longer the case, and now I have to look up a little. After the first
set died, I put back in the shelves and moved everything beneath the
LCD. I don't want to take chances. The LCD sits topmost now without
anything obstructing it (before, with the first set, the LCD was
marginally enclosed yet within manufacturer parameters given free
clearance). There's also never been backing material, or front
framing, so it's just shelving that always been free space front and
back. It's not actually quite fair to say it's cooler, lacking the
exact setup as before. Top shelved, though, the replacement unit -
seems- to be, unless there's a later model discrepancy and greater
design or engineering efficiency for heat dissipation, I'm unaware.

Aside from longevity, that is after awhile, I may adapt to the idea of
that 32" of 180W radiating in my face, if I replace it with a newer
37" or larger and use the 32" instead a 19" Samsung LCD on this
computer (hm.... Even with the 32" LCD's "power saving mode", I
wonder, the Samsung takes a beating from rigorous use, being switched
on and off frequently from a computer running 24/7.

Yes, thanks for your reply. The heat produced is
less than my old 19 inch CRT but i am concerned
when my JVC was warm yet a friends Toshiba
LCD 37 inch and another of my same model
seemed to produce no heat at their top vents.

Manual gives no clue Nor the faqs at the JVC
web site. I sent a message re my above post
to the support at jvc.com

Its on a cadennza well away from anything else.
Due to my heat concern, i have my 19 inch
house fan pointed its way which really helps
to keep the vent tempurtures below 10F
above ambient.

Perfectly normal.

I was surprised too, when I stood near my 37 inch lcd hdtv. The
heat was noticable from a foot or two away. LCD is supposed to be
cool, I thought. You pay a price for that beautiful picture. Now if
it was like the LCD on my wris****ch, it could run on 10 watts.
