Product Description

Toshiba takes digital light processing (DLP) technology into the future with the 52-inch TheaterWide 52HM84 HD-ready rear-projection TV. The 16:9 52HM84 uses a proprietary system called TALEN (Toshiba Advanced Light Engine); based on the Texas Instruments HD2+ DLP chip, it enhances brightness and contrast while keeping the 1,280 x 720 progressive resolution (720p). Toshiba's TheaterWide TVs challenge direct-view CRT models when it comes to reproducing deep blacks and details in dark or shadowy scenes.

Toshiba takes digital light processing (DLP) technology into the future with the 52-inch TheaterWide 52HM84 HD-ready rear-projection TV. The 16:9 52HM84 uses a proprietary system called TALEN (Toshiba Advanced Light Engine); based on the Texas Instruments HD2+ DLP chip, it enhances brightness and contrast while keeping the 1,280 x 720 progressive resolution (720p). Toshiba's TheaterWide TVs challenge direct-view CRT models when it comes to reproducing deep blacks and details in dark or shadowy scenes.

What is DLP?
The DLP processor DLP, or digital light processing, is a technology that bounces a colored light beam across an array of hundreds of thousands of hinge-mounted microscopic mirrors attached to a single chip, called a micromirror device (below, pictured with the head of a pin).
DLP mirrors dwarfed by the head of a pin
Each of the mirrors can be pointed toward or away from the light source thousands of times per second, providing not only minute color detail, but also sharper resolution than even LCD displays.
Detail of resolution comparison between LCD and DLP
This set is HDTV ready (it needs an optional high-definition receiver to get HD signals), but can improve standard-definition video, thanks to Toshiba's multistep PixelPure video processing system, which optimizes the three main picture quality factors: resolution, contrast, and color. All incoming signals are converted by the built-in scaler to match the DLP chip's native 720p resolution.

PixelPure encompasses eight different processing circuits. Among its components are 6.2- million-pixel oversampling (for higher perceived resolution), real-speed progressive scanning (which uses additional sampling points to create smoother diagonal lines), a Magic Square algorithm (for smooth, natural color gradation), Dynamic Contrast Enhancer (for higher perceived contrast and increased color saturation), and Color Detail Enhancer (to maintain fine image detail in color-saturated areas).

DLP technology uses an optical semiconductor, known as the Digital Micromirror Device, or DMD chip, to digitally manipulate light. The chip contains a rectangular array of up to 1.3 million microscopic mirrors, each measuring less than one-fifth the width of a human hair. A DMD panel's micromirrors are mounted on tiny hinges that enable them to tilt either toward the light source (on) or away from it (off), creating a light or dark pixel on the projection surface. The bit-streamed image code entering the semiconductor directs each mirror to switch on and off up to several thousand times per second, enabling the mirrors to reflect pixels in up to 1,024 shades of gray.

The HD2+ DLP chip ensures an ultraclean image by filling in the dimples, or vias, in the mirrors to avoid stray light. It increases both brightness and contrast, resulting in an impressive color-corrected contrast ratio (2,200:1) at 1,100 ANSI lumens. The set's TheaterFine HD Super Fine Pitch screen reduces the physical space between the lines on the lenticular screen, resulting in a finer, sharper, more detailed picture.

Toshiba's DFine Hi-Speed VSM (velocity scan modulation) improves contrast and overall picture sharpness, while the CableClear DNR+ digital noise reduction optimizes poor NTSC signals from antenna or cable, further eliminating video noise ("snow") for a clean, crisp image. Cinema Mode circuitry (3:2 pulldown switch) identifies original film-based content from DVDs, then reassembles the frame sequence to more accurately reproduce the original 24-frame-per-second material.

A 3-D Y/C (4 MB, 10-bit) digital comb filter with Vertical Contour Correction helps eliminate dot crawl and color bleed and significantly reduces detail noise, seen as shimmering or flicker, in complex or intricately detailed scenes. Color temperature controls allow you to adjust white balance. The Warm setting reduces the color temperature to an NTSC standard 6,500 degrees Kelvin and delivers a redder image that is ideal for display in a dimly lit room. Medium and Cool setting provide a progressively bluer image for the best picture as room light levels are increased.

The 52HM84 has plenty of inputs for connecting all your audio and video components. In back you'll find two RF, two composite video, two S-Video, and two HD ColorStream component video, as well as a High-Definition Multimedia Interface (HDMI) digital input. HDMI is an uncompressed, all-digital audio-video interface that supports standard, enhanced, or high-definition video, plus eight-channel digital audio--all on a single cable. A set of front composite and S-video inputs make hooking up a game console or camcorder a snap.

Other features include HD Window dual-tuner POP (picture-on-picture) with PIP sound for listening to two programs simultaneously, the new Radiance DC lamp with high brightness and lower power modes for extended life, individual audio-video settings by input type, sleep and wake timers, Real Speed progressive scanning to create smoother diagonal lines, the Color Transient Improver for sharp transitions on color changes without bleeding, and the Color Detail Enhancer to maintain fine image detail in color-saturated areas.

Aside from the 20-watts-per-channel stereo speaker system, the 52HM84 uses MTS for programming with stereo sound, and SAP for receiving a second audio track in another language. Meanwhile, SRS WOW combines 3-D Sound (simulated surround sound from any stereo audio) with TruBass (yet another low-frequency enhancement) and Focus (which clarifies voices). The StableSound volume leveler eliminates drastic volume spikes while changing channels or when channels go to a commercial break.

After over a year you'd think Toshiba would have enough lamps on hand to replace all of the faulty ones they sell with their TV?

Size Name: 52" Screen Size Verified Purchase
I spent over two years looking at high definition televisions before settling on the Toshiba. The features that sold me were the outstanding picture quality, both brightness and clarity, as well as the very reasonable price for the size and features of the set. I spent several months watching the prices in the retail stores, but never found the price dipping much below the $3000 that every retail store seems to want to sell it for.

I have never purchased an item as large as this from Amazon, and I was a bit reluctant to do so. Given the reviews to date and comments regarding reliability, I was concerned about buying from a company that did not have a good extended warranty option available. While Amazon does sell third party contracts, I did not find them to be particularly well known. I was leaning toward buying the unit from Sears, where the extended warranty is supported by a very large service organization, and the organization is staffed by full time Sears employees who have always been very professional with other items I have needed service on. The down side was a $700 difference in price between Sears and Amazon.

What finally convinced me to choose Amazon over the local retailers was that I was able to double the warranty by charging it on my American Express card. My only other hesitation was that I needed the unit carried up a flight of stairs, and while I knew that the local Sears delivery person would carry it up, I was not sure what to expect from a trucking company contracted by Amazon.

My set was delivered yesterday by Eagle Freight. They scheduled my delivery between noon and 5:00 pm, and they showed up at 4:00 pm, after first calling to let me know they were on their way.

I researched televisions before buying the 52HM84. I compared DLP, LCD and Plasma. I decided on the DLP due to its size and picture quality. I had narrowed my research down to the Mitsubishi and the Toshiba - since these both us the HD2+ DLP chip. The Mitsubishi had a glare on the screen and the Toshiba didn't. The quality of the picture is outstanding. The technology to clean up messy analog signals is outstanding. I could not be happier with this purchase. I highly recommend a buyer to purchase the matching Toshiba ST5284 stand for the set. Together - the set is perfect! GOOD WORK TOSHIBA!

Size Name: 62" Screen Size
I have upgraded from a high def Toshiba 4:3 projection TV. I ordered this TV from BuyDig as they gave you 10 days in home in case something was wrong with the TV. Currently their price is the same here but with threshold free shipping and $99 White Glove service. Amazon will have you deal directly with the manufacturer in the event there is something wrong with the TV upon delivery. At first, I was a bit disappointed with the picture until the cable company came to bring a second HD box for the 4:3 TV thatI had moved to the bedroom from where the new TV was going. The cable Tech set the HD box to normal with 1080i and the picture was amazing. As good as any picture I had seen in the stores. Whether it was DLP or plasma. I am not using the DVI hookup rather I am using the High end composite cables. The unit is also hooked up to a home theater. I have the TV set up in the basement which has always been the TV room in the house. Im glad thats where it is as I was able to move the sofa back to a viewing distance of between 11 to 12 feet. Too close and its overwelming. If the TV had been in a normal size room I would have selected the 52" monitor. I had selected the Toshiba over the competition due to the higher end chip and my previous experience with Toshiba. In addition, in relation to the other DLP models it was less expensive with in my opinion a better picture. Finally, I purchased the matching stand from ABT electonics as they asked $289 which included $20 shipping. The matching stand is a must if you are spending the money on this TV. The only thing I will continue to reseach is getting a replacement lamp so when the day comes when that goes I can change it as the instructions to change it appear simple. Enjoy this set!

Size Name: 46" Screen Size
We received the TV in mid Dec/2004. We like it a lot.

Worked great for about 2 weeks and suddenly would not turn back on.

Figured out that if we unplugged it, it would come back on after being unplugged for a minute.

The authorized Toshiba service people here have given up after 2 service calls and 2 parts replacements.

Each time the replacement part was ordered it took 6 weeks!

We have been limping along by unplugging it every night.

3 weeks ago the lamp blew. The lamp has a 1 year warranty and it was less than 6 months old.

BUT! Toshiba doesn't have any. It has been on backorder for 3 weeks now and they have no idea when any will show up. Each week they say "Please try again in a few days".

It's a great tv when it works, like it a lot. But, going on to a month without any tv is no fun I can tell you.

Toshiba found a replacement bulb soon after I wrote this review and express shipped it to us. Since then we've replaced the bulb twice (about once a year) without any supply problems. The bulbs are expensive -approx $200!
We figured out the issue oursleves with not being able to turn it back on - it has something to do with using an HDMI cable to connect the tv to an old Dish Network DVR. We switched to using composite cables and everything has been fine since.
