Rear screen projection TVs are dead

Mitsubishi has announced the end of its rear projection screen TVs. For many years if you had big-screen TV, it was typically a rear projection style unit. As pricing on LCD and plasma TV sets came down and screen sizes increased, consumer interest in rear projection TVs waned.

Mitsubishi was the last manufacturer producing these relics from the past, but the company has informed its authorized service centers 73-inch, 82-inch, and 92-inch DLP projection TVs will be discontinued.

Mitsubishi Electrical Visual Solutions America (MEVSA) president and CEO Junichi Nose stated that the change was part of an "important change in business direction, which will necessitate a corresponding restructuring of the MEVSA organization."

MESVA's Max Wasinger added, "We are in the midst of an orderly exit from the DLP TV business. MEVSA will now focus on B-to-B (projectors, display wall, printers, digital signage, monitors, etc.) and the home theater projector business."

Mitsubishi's line of projection screen TVs were far from inexpensive. The 75-inch LaserVue TV sold for about $4,000 at retail locations around the country.

80lbs is very manageable, though 18" is less manageable.
I think these would be great tv's for the optimal room setup - but a 2 inch thick tv you don't have to worry about having the perfect room setup.

Also - did they ever fix the viewing angle? Horrible viewing angles is what put me off of DLP - but it's possible they have improved this.

I've never noticed an issue really with viewing angles on DLP Rear Projection TVs, but those original Rear Projections I totally get what your saying.

Unless you are talking about the weird viewing issue some people have with DLPs in general...that I don't think is something you can fix with the TV.

Amazon dot com - Westinghouse 40" 1080p LED HDTV - $400 to the door. IDK, but I don't think I could bring myself to buy a rear-projection mainly because it's becoming so cheap to purchase an LED TV that has decent quality, and I can put it pretty much anywhere in the house - maybe if I had a larger, or better room setup as someone else mentioned...

All rear projection sets have a viewing angle problem. There's a tiny array of fresnel lenses just behind the screen which directs most of the light forward, causing image brightness to drop off if viewed from a different direction. In other words, the brightness falls off towards the sides because that light is being redirected straight forward to increase brightness when viewed straight on.

The problem with rear projection (and also front projection) is that all the light has to come from a single source - a bulb which is focused by a lens, shines onto a DLP, then goes to the screen. This means it gets really hot where the light is most concentrated. That limits the maximum amount of lighting you can use before overheating and melting start to become an issue. By the time that light is spread over a large screen, it's pretty dim. And so you need to concentrate it within a narrow angle to maintain brightness.

LEDs and older LCDs on the other hand can spread the light source out along the edges of the screen, allowing for higher overall light output without as much heat issues at any single point. LEDs in particular run very cool (are very efficient). Ideally you'd be able to use them in a projection TV, but they don't yet produce enough light to replace a halogen or arc bulb. I was really hoping laser LED projectors would make up for this deficiency, but that technology seems to have fallen by the wayside.

My Samsung RPTV uses an LED light engine (made in New Jersey BTW). It is 5 years old. You aren't saying anything new.

Personally, I've never understood the attraction to many "thin" hang on the wall TVs for home theater setups. Good speakers are going to have depth, the AV equipment has depth, so does the Blu-ray. And I haven't seen any cable boxes made flat either. Most people don't install their equipment in another room or closet.

So for most peoples homes, the AV equipment and speakers hang out, so why does the TV need to be flat. Gives a recessed look that's not too flattering.

I'll agree that the flat TVs are ideal where you don't really have too much equipment.

Also - did they ever fix the viewing angle? Horrible viewing angles is what put me off of DLP - but it's possible they have improved this.

DLP always had very good horizontal viewing angles but poor vertical viewing angles. But to be honest, on DLP TVs this size (65"-90"), it's almost impossible to get into an angle where you see it. You literally have to be 1 ft from the TV and have your head on the ground or near the ceiling to have the picture wash out. Certainly not a position most chose to watch TV from.

I had absolutely no trouble lifting my 42" DLP myself when I had it. I believe it was about 40 lbs.

But 42" is no longer a relevant number.
You can get a 42" LCD TV for less than $600 which is ridiculously light and runs ridiculously cool.

That's kinda the point. Even the 7x" LCD screens are becoming crazy cheap --- check them out in Costco, or the Best Buy house brand Insignia some time.

Yes, snobs can find a thousand things to complain about in these cheap TVs; but the bottom line is that once a technology is "good enough" convenience beats supposedly better specs every time. We have seen this over and over again (starting, perhaps, with CDs, then on through MP3s, now in the space of dedicated game consoles. Every time the fans rise up and deny reality, insist that, no, the wonderful attributes of their favored technology are somehow relevant to this discussion. Mitsubishi, at least, hires realists who understand how the world works.

A 42" TV is worthless for home theater. Even casual viewing.


Because you will never see the resolution. In order to 'see' the 1080p resolution on a 42" HDTV you have to sit 5.5' away from it. If you are watching it from 12' away you aren't seeing any quality beyond a plain old DVD resolution, aka TV from the 50s-90s.

The LaserVue TVs are 13" deep, which is about the same depth as an AV receiver or Satellite DVR box.
