The latest
2004 line of CRT Sony Projection TV sets represent the best option in
terms of picture quality and size for your dollar. They may not be as
compact and lightweight as LCD or DLP rear-projection
sets, yet the Sony CRT projection HDTV's are relatively inexpensive.
Further more, picture quality
is among the best one can find, with unbeatable black level performance no
other LCD or DLP projection TV can achieve.
Introducing the Sony 'WS655'
Series of CRT Rear Projection HDTV Sets
The 'WS655'
series is Sony's 2004 line of CRT rear projection TVs. These
represent a step-up over Sony's 2003 KP-xxWS510 series.
This latest series of Sony wide
screen CRT RPTVs comprise the
Sony KDP-51WS655, a 51" CRT
rear projection TV, and its bigger brother, the 57"
Sony KDP-57WS655
HDTV.
Both sets come with identical
features and specifications except for a different screen size.
Main features include:
-
HD MICROFOCUS™ CRT and Lens System
with DRC® MultiFunction Technology and MID®-X Multi Image Driver Circuitry
-
Built-in HDTV ATSC tuner for
over-the air reception of high definition broadcasts with PIP support
-
CineMotion 3:2 pulldown technology
with auto detect and reversal to display a film-frame-accurate picture when
playing back 24-frame-per-second movies.
-
Playback Auto 16:9 Enhanced Mode
-
Built-in enhanced Memory Stick®
media slot to view your family photos onscreen and listen to MP3 audio.
-
CableCARD™ Slot for digital cable
reception with no need for an extra set-top-box.
-
A host of inputs and output -
including a HDMI/HDCP Interface

These CRT-technology-based Sony projection TVs represent a relatively inexpensive
large screen TV option for the home theater.
OK, maybe not as cheap as some
other brands, but surely affordable considering
the accompanying list of interesting features and technical specifications.
In fact, the smallest in this series
of Sony projection TVs - the
51" KDP-51WS655 is selling
online at less than $2,000, while the slightly bigger model, the 57"
Sony KDP-57WS655 HD-CRT Projection TV is selling
at amazon for less than $2,100 - worth considering over the smaller 51"
model if you have got the necessary room space.
An interesting list of
features, enhancements, and high-tech specifications
Sony CRT Rear Projection:
A
Detailed Technical Analysis
As
indicated earlier on, both products in this series of Sony
projection TV sets share the same technical specifications and features -
the only difference being a different screen size. Interesting to note here
that these relatively inexpensive Sony CRT rear projection models share a
number of
similar audio/video specs and features found on the more expensive Sony LCD
projection TVs.
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 projection TV sets 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,
Digital Reality Creation® (DRC)
Multifunction:
These CRT Sony rear projection TVs are also capable of making a good show out
of a standard-definition video signal through Sony proprietary
Digital Reality Creation
MultiFunction Circuitry.
Unlike conventional line doublers, the DRC Multifunction feature replaces
the signal’s NTSC waveform with the HD equivalent, while doubling the number
of vertical and horizontal lines. This results in four times the picture density for
quality sources, such as DVD, satellite and digital camcorders.
In the process, it also increases the video signal's signal-to-noise ratio
to ensure rich, natural-looking images from any source.
In addition, the 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 CRT Light Engine: These CRT Sony projection TVs make use of
quantity three High Definition MICROFOCUS™ 7-inch high
brightness monochrome type picture tubes optically coupled with 3 large diameter F1.1 lenses
in a
horizontal in-line arrangement and using a liquid cooling system. The use of
HD MICROFOCUS™ CRT ensures bright crisp clear high definition images.
The
convergence process uses both Sony proprietary auto Flash Focus as well as
63-point manual adjustment.
Other
picture enhancement features include:
-
Clear Edge VM™ Wideband Velocity Modulation,
which improves the definition at picture edges, creating sharper images
by slowing the CRT (cathode-ray tube) beam's horizontal scanning during
demanding work - say, when rendering transitions from light to dark
parts of an image - and speeding it up when scanning easily rendered
sections, like broad dark areas.
-
HD Detailer™ Wide Band Video Amplifier with its high bandwidth frequency
response, is capable of supporting finer picture quality, especially for HD sources.
-
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.
-
Screen Surface:
The screen makes use of a high contrast screen with an A/R (Anti-Reflective)
coating to help reduce glare.
Other features include:
-
Built-in Memory Stick media slot
allows quick, easy viewing of digital photos (JPEG
images), MPEG-1 video, as well as listening to MP3 audio.
-
A 3D Digital Comb Filter - this is the best type of comb filter
available today since in addition to separating the Y (luminance or
black and white) and C (chrominance or color) elements of a video signal, a 3D Y/C
filter also performs two additional key functions - that of comparing
three consecutive horizontal scan lines within a single video frame, and
also of analyzing each frame in advance. In this manner, a 3D Y/C filter
is able to ensure the best possible picture.
-
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).
-
Inputs and Outputs: These Sony
projection TV sets come equipped with a full range of inputs and outputs
- an HDMI (High-Definition Multimedia Interface), which permits a direct
digital connection with a compatible DTV set-top box, 2 component-video
inputs, 4 composite-video inputs, 3 S-video inputs (with 1 each
composite-/S-video on the front panel for ready connection to a
camcorder or gaming console), and 2 RF coaxial inputs for hookup with an
older VCR, cable box, or antenna.
HDMI
is 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.
-
Audio: These CRT Sony projection TV
sets support MTS Stereo and Auto SAP, and include an onboard 2-way speaker
system powered by a 20 watts per channel (x 2) amplifier. An optical
digital-audio output is also included that lets you pass a Dolby Digital
5.1-channel surround-sound signal to a compatible audio/video receiver
or other surround processor for powerful, enveloping sound through your
home theater multi-channel speaker system.
-
Parental Control: (V-Chip) allows parents to block unsuitable
programming from younger viewers.

Concluding Remarks
Pros: Considering the list of features
and technical specifications, these Sony projection TV sets represent an
inexpensive - presently selling at around $2000 online - HDTV big
screen option for your home theater.
The use of the HD MICROFOCUS CRT and lens
system renders these sets capable of delivering superb picture quality with
vivid, bright detailed images - better than many other similarly priced rear
projection TVs. Sound quality is very good for a TV. In addition, the built-in HDTV tuner and cable card slot
represent savings of a few hundred dollars in the form of a dedicated
set-top-box.
Cons: None considering the price - except that they are bulky and
heavy - BUT this applies to all CRT type rear projection TVs.
