LCD Flat Panel vs. LCD Rear Projection
 

Can someone point me to a web site that discusses LCD Flat Panel vs. LCD
Rear Projection? Particularly as to their respective viewing cones.
Thanks.

Burn-in on RP LCD is another concern, due to the
dramatically higher watts/sq.cm. vs. backlit LCD.
Have a look at:
"Long-Term Data Projector Color Performance Test"
http://snipurl.com/sj6q
from:
http://www.dlp.com/dlp_technology/dlp_technology_white_papers.asp
Keep in mind that TI has a dog in the race :-)

RPTVs (CRT, LCD, DLP) with uniform on- and off-axis
performance may well exist, but I have yet to see one.
Everything I've seen so far has objectionable
light-fall-off/hot-spot. But if I were inclined to get
an RPTV, it would probably be DLP.

Still waiting for LED-backlit 1920p 8-bit 10mS LCD,
at a reasonable price in the ~40in range. DLP is already
there, except for the uniformity problem, and possibly
issues related to single-chip/color wheel (soon to be
LED color switching).

AVSForum.com will have the information that you need.

Just as an FYI, I have been burdened with getting rid of two 57" AQUOS
and two 65" AQUOS sets that OneCall.com has in their warehouse. For
some reason we had them shipped to us instead of the normal drop
shipment situation that Sharp forces everyone to follow. I am willing
to sell them at cost in order to just get rid of them if you decide you
are interested. (No, can't post the price or Sharp will have a cow and
I will be in the unemployment line.)

Email me if you are interested though and put AQUOS somewhere in the
title of the email so I actually read it. ;-) I will then call you to
(or give you my number) so we can work out the details.

Thanks,

Well if you do, hope you have better luck with it than I have had with
mine. My Sharp DLP was great for almost six months and then it
started developing a noise. After a fan change out, the servicer
determined it was the color wheel making the noise. So they installed
a new light engine. That took care of the noise but then I had a
problem with the picture. Many, but not all, programs I watched, both
SD and HD, had problems with the color. It's hard to describe exactly
but there are smears of color that shouldn't be there. Where it
really shows are on tight shots of people--their skin will have
reddish blotches like they have some kind of skin disease. There are
other ways that it shows that are harder to describe, but it makes for
a crappy picture. Yet I can turn to another channel and get an
absolutely beautiful picture.

What my authorized servicer decided to do after consulting with Sharp
was to replace the light engine again. They brought the set back
today, and it didn't help at all. The guy made a comment along the
lines of "in the old days I'd just make some adjustments, but I don't
make any to these sets." Then he made another comment about lack of
support from manufacturers.

I don't know what else I can do at this point but to call Sharp Monday
and raise some hell. I have a three year extended warranty on the
damn thing but that's worthless if I can't find someone who can
actually repair it!!

Meanwhile the same programming on my Westinghouse 37" LCD looks great!

indeed adjustments that can be made in the service menus. The one that
strikes me with a the light engine replacement is the color wheel phase
such that the DLP activates when the 'window' is centered. This _is_
an adjustment for the Samsung. The service manual is a .PDF and cost me
like $30 for both the monitor and set top box (ours is old -- 12/2003)
on a CD. You might look into that possibility. I know you have the
warranty but sometimes it's worth checking it out yourself.

Thanks, G², I'll look into it.
