The latest
Grand WEGA Sony LCD projection TV sets are taking home
entertainment to the next level.
Picture quality is superb, come with an
integrated HDTV tuner, and they are stylish and slim. Price-wise, they compete well with similar
products from other brands.
We
review some of the top-selling products in the range of LCD rear
projection TVs from Sony to see what's on offer for the home theater.
Introducing the Sony Grand WEGA
'KDF' Range of LCD Rear Projection HDTV Sets
All products in the
'KDF' range of Sony rear projection TV sets share similar features
and specifications.
The real major differences between the various models are different product
dimensions and weight - which vary according to the product screen size.
The smallest in the Sony's
line of Grand WEGA LCD RPTV's is the
Sony KDF-42WE655 - a 42-inch wide screen rear projection
HDTV.
The other extreme in terms of
screen size - not only within the Sony range but also within the
full range of available rear projection TVs from other major manufacturers - is
the 70-inch wide screen
SONY KDF-70XBR950
LCD rear projection TV. Surely
not as slim and lightweight as the rest of the models, but at such a huge
display size, this is more than expected for a rear projection TV.
Other popular products in the range of Sony Grand WEGA LCD rear projection TVs
include:
-
Sony KDF-50WE655 : this succeeds the highly rated Sony KF-50WE610 and
is the 50-inch version of the KDF-42WE655
-
Sony KDF-55WF655 : this is the 55-inch version of the KDF-42WE655
-
Sony KDF-60XS955: this 60-inch HDTV set is a step-up version of the
KDF-60WE655.
All sets include an integrated HDTV tuner that is capable of receiving
over-the-air broadcasts, as well as digital cable TV. There is also a cable
card slot, a memory slot to view your digital camera pictures, and 2:3
pull-down. In addition, all models except for the KDF-70XBR950 come
with a HDMI™ interface as standard.
Thanks to
the use of Sony proprietary WEGA light engine and the latest LCD ('Liquid
Crystal Display') micro-display projection technology, these Sony rear
projection TV sets are capable of delivering exceptional picture detail and
vivid bright colors across the full screen surface.
In addition, though not as slim as a
wall hanging Plasma TV, yet these Sony LCD projection TV sets are stylish,
relatively lightweight, and slim - requiring no more than 15 to 20 inches in
depth - depending on the screen size. The only except is the 70" Sony LCD
rear projection TV with its 25.5" depth - yet it is still compact in
comparison to what would be required for a CRT RPTV.

Surely,
Sony are the undisputable leaders in the field of home entertainment and
video technology - their products have always been synonymous with quality
and reliability. However the real seller for these great feature rich
Sony LCD projection TV sets is not the Sony brand name but the price.
They do not come cheap - maybe a bit more expensive, but still compete well
with similar products from other brands.
In fact, the smallest in this range
of Sony LCD rear projection TVs - the
Sony 42" KDF-42WE655 is selling
online at around $1,900. If one were to take into account the slight
difference in screen size, this would fall in line with the slightly bigger
46-inch
Toshiba 46HM94 DLP HDTV. Similarly, the Sony 50-inch
and the 55-inch models are within the same price bracket of the
Toshiba 52HM94 52" DLP HDTV.
Sony LCD projection TVs only start to get
somewhat more expensive than the average with the larger 60-inch and 70-inch
wide-screen models, with the 60-inch model selling on amazon at
$3,300.
Even so, these prices for the Grand
WEGA range of Sony LCD projection TVs still
contrast heavily with the prices of plasma TV sets, which at $5,000
for a new 50-inch HDTV plasma model, renders plasma a relatively expensive
big screen option.
An interesting list of specifications,
features, and enhancements.
Sony LCD Projection TVs: A
Detailed Technical Analysis
As
indicated earlier on, these products in the 'KDF' ranges of Sony rear
projection TVs share very similar specifications and features - with the
real significant difference being a different screen size.
All
sets feature a wide 16:9 aspect ratio screen and offer
compatibility with standard-definition 480i,
enhanced-definition 480p, and high-definition 720p and 1080i signals.
Integrated HDTV Tuner:
These
Sony LCD projection TVs come with a built-in HDTV tuner which can receive both
over-the-air broadcasts as well as digital cable broadcasts (ATSC and QAM).
This means that there is no need to spend a few hundred dollars in an
external HDTV decoder to feed in high definition signals.
The tuner supports
picture-in-picture through Sony's TwinView PIP, a feature that lets you view any 2
sources simultaneously - side by side, even at different image resolutions,
These Sony LCD projection TV sets are also capable of making a good show out
of a standard-definition video signal through Sony proprietary
Digital Reality Creation
MultiFunction Circuitry. This raises standard definition signals to HD
quality to display clear, stable images from any video source. MID-X Multi
Image Driver Circuitry scales all incoming standard and high definition
signals to the configuration of the panel without degrading signal quality.
Sony WEGA LCD Light Engine: Sony rear projection TVs utilize LCD
technology in their light engine. Sony make use of 3 different 1,366 x 788
wide-XGA format, high-resolution LCD panels, one for each of the RGB color
component (resulting in a total of 3.28 million dots of resolution). This
calls for a more complex optical setup but at the same time, it gets rid of
the color wheel found in most DLP sets - often associated by some with the
rainbow effect.
The WEGA Engine system
maximizes picture performance from any video source by minimizing the number
of digital-to-analog conversion processes.
The optical engine used in
these Sony LCD projection TV sets also
features a special 11-element lens system responsible for the lightweight,
ultra-slim cabinet. The lens system bends the light path, creating an
ultra-short focal point while maintaining high brightness. A 100W or
132W user-replaceable ultra-high-pressure lamp is used as the light source;
lamp wattage varies according to model. This proprietary system delivers
vivid images from the center of the screen all the way to the edges.
This set-up frees the user
from having to make any convergence adjustments. In addition, as with other
micro-display projection technology, these Sony LCD projection TV sets do
not suffer from burn-in; this is not the case with phosphor-based CRT and Plasma
displays.
When it comes to these Sony
LCD projection TV sets image quality, our only minor complaint
is their black-level
performance, or rather their ability to accurately render black and very
dark picture areas. Surely there has been a huge step-up from some previous
models, something which brings Sony LCD rear projection TV sets on par with
most competing DLP models - but still not as good as some CRT-based RPTV's.
Sony's Digital Reality
Creation (DRC) circuitry ensures high picture resolution, while
proprietary Direct Digital Circuitry increases the video signal's
signal-to-noise ratio before it reaches the DRC circuit, ensuring rich,
natural-looking images from any source.
3:2 Pulldown: Sony's
CineMotion 3:2 pulldown detection and reversal is a handy feature for
watching progressive-scan movie programs in their native 24-frame format.
Digital video mastering introduces a common distortion when adjusting 24
frames-per-second movies to 30 fps video; 3:2 pulldown digitally corrects
this distortion, removing the redundant information to display a
film-frame-accurate picture.
Other features include:
-
Built-in Memory Stick media slot
allows quick, easy viewing of digital photos (JPEG
images) and MPEG-1 video. It can also display customized slide shows
using MP3 files for background music.
-
Channel Fix
lets you select a specific TV channel (3, for example) for cable box
reception. Then you can control a compatible cable box via the TV remote
without inadvertently changing the TV from Channel 3.
-
A CableCARD
slot
gives
you the option to connect to cable TV without a set-top box, giving you
access to analog, digital cable, HDTV, and premium cable channels like HBO
and Cinemax (if supported by your cable company).
-
Sony's
exclusive S-Master 1-bit digital amplifier produces 15 watts per
channel (x 2), ensuring high power for superb, clear dialog.
-
HDMI
(High-Definition Multimedia Interface) - a lossless, uncompressed,
all-digital audio/video interface to link the set with any audio/video
source (such as a set-top box, DVD player, or AV receiver). HDMI supports
standard-definition (SD), enhanced definition (ED), or high-definition
(HD) video, plus multi-channel digital audio - all using a single cable. It
transmits all ATSC HDTV standards and supports up to 8-channel digital
audio, with bandwidth to spare to accommodate future enhancements and
requirements.
Note that HDMI Interface is not
available on the Sony KDF-70XBR950; this is a slightly older Sony LCD
projection TV model that was released in late 2003; in
comparison, the other models were released in late 2004.
A few minor
differences
We have
stated that these Sony rear projection TV sets share very similar
specifications - with the real major difference being a different screen
size. This doesn't mean that there aren't any differences in the supported
features and enhancements between the various series.
For
example, the XS955 Series
of Grand WEGA televisions offers additional features over other
products in the 'KDF' range of Sony LCD projection TV sets, including
advanced menu functions that are typically found only in service menus:
-
Gamma
correction (bright and dark balancing),
-
Black correction (enhances contrast),
-
White balance (fine-tunes white intensity),
-
Detail enhancement (sharpens the picture), clear white (emphasizes whites),
and
-
Live Color with an assortment of enhancement option levels - this is an
innovative circuit that emphasizes blues and greens without affecting reds
for a more natural, vivid picture.

Concluding Remarks
Pros: Affordable sets from the leader in
the field. These Sony LCD projection
TV sets represent a huge leap forward in the performance of LCD rear-projection televisions - in particular when it comes to the black-level
performance. Still not exactly in line with the bulkier CRT-based RPTV's,
yet these Grand WEGA line of DLP RPTV products compete well with their DLP
counterparts.
In addition, the use of
three different LCD panels - one for each color component - in place
of the typical color wheel used in some other rear projection TVs ensures
that viewers will not suffer from any rainbow effect.
Cons: These Sony LCD projection TV sets do not come with lamp
brightness adjustment - a feature available on the Toshiba range of DLP rear
projection TV sets. This may render a too bright a picture for viewing in a
darkened room - in particular with the smaller screen size sets.
Fan noise may be noticeable
especially during passages of low volume sound.
Our final complaint concerns channel labeling - no matter how much time it
takes to label all your favorite channels, at the instant you perform a
scan to update the channel programming on your Sony LCD projection TV, all your labeling
work goes down the drain as the scan process seems to erase all channel
labels!
