I was looking at plasmas on ebay and stumbled across laser TVs. I don't keep up with AV anymore and this is the first I've heard of them. Are they any good?

They've only been available for a year or so, I think right? And, isn't Mits the only one shipping one at the moment?
I keep forgetting to check them out. I gotta get into a dealer here and see if I can find one.
I imagine some of the glamour just isn't there with them because everybody seems to be in "I wanna hang it on the wall" mode, and this is a boxy box more like a traditional (well, digital, actually) rear-projection set.
Gotta go check one out.

They are about 10-12 inches deep and the 65" model weighs around 130 lbs. And you can buy a special wall mount bracket from Mitsubishi to hang it.
What else would you like to know?

I'd say even "only" 10-12" deep is going to look pretty goofy hanging on most residential walls, unless you have a "cove" for it to occupy. Probably great to replace CRT RPTV's and in other types of installs... Commercial built-in type deals for bars could be great, I suppose. I can't imagine bulb maintenance costs in these bars where they have 10-12 LCD/DLP RP setups going 12+ hours/day. They'd burn through a thousands of dollars a year in bulbs, I'd think!
What else? I think what Phil's question was is what do they LOOK like? I mean, what does the picture look like? Is it like CRT, but sharper?
Oh, I have a question too, Mac... Do you know how they handle deflection? Rotating mirrors? Piezo-driven lenses or mirrors?

As far as a wall hanger I some what agree. A regular flat panel is at around 4.5" deep so its actually only about 5 to 6 inches deeper and at the smaller size one of 65" screen I would think this would take away from the ugly affect. But there are still those who want as thin as possible. But what if the picture on the laservue was WOW!!!!! Amazing difference like night and day. Those who are more concerned about PQ would probably be ok with the thicker device. But alas, many people dont even notice PQ and would still want the thinner flat panel.
From what I here from the ASC guys who have been factory trained on the laservue, they say the pic is amazing. It is DLP based with a 1080 DMD. The front screens are glass instead of plastic like past RPTV's. The lasers are class 4 which will cause eye damage and some believe this is why the screen is glass. All I can say is if the game remote goes through the glass you better cover your eyes quick. Power consumption is suppose to be way less then everything else out there.
I think the reason these are slow coming out is because of the problem in developing a blue laser. The technology for a low cost easy production blue wave length laser is just at 10 years now. Hard to tell how it will prevail. I think its been for sale now since later 2008.
As far as reliability, no techs that I know and that are Mitsu ASC have not reported any repairs. So either they are holding up well or there are not many out there yet.
I found a best price of 3999.00 for a 65" which seems in the park with LCD/plasma at that size. And if PQ and reliability were outstanding you think they would be selling like hot cakes. But people just seem to want those skinny, poorly ventilated, parts burning units instead.
I think the laservue comes in a 73" model also. I'll see what else I can find out. I can probably get a copy of the training manual if you guys are interested.
A new technology is also coming that I'm sure you'll hear about soon. Its LPD (laser phosphor display) but I'll leave comments on that for another thread.

Some review info:
The picture quality is fantastic across the board, from unruly action flicks to serene, Sunrise Earth-like films.
And the colors. You're not going to find a set that is capable of displaying colors quite like this one. If you're a Nebraska fan or you cheer for a team sporting a cardinal for a mascot, you're set. If George A. Romero's film collection never leaves your Blu-Ray player, or you're a Republican, you'll love the LaserVue.
LaserVue technology is a significantly lower level of power consumption compared to other HDTV technologies. The Kuro 60" plasma requires 524W for operation; a Sharp Aquos 65" LCD requires 525W; Mitsubishi's 65" LaserVue TV only needs 135W. On average, the LaserVue required one-third the power of a comparably sized LCD and one-fourth of a similar plasma set.]

OK, cool... Thanks for the info, Mac. I'm not a Nebraska fan, but I'm definitely going to have to get into a store and check out the "Republican reds".

According to laser-tv.org Sumimoto just developed the first "true" green laser last year. Before that they had to "double the frequency of an infrared laser" (HTH do you do that!?), but now Sumimoto can make a 531nm laser. Dunno how that translates to CIE coords but presumably it's the right color for TV.
EDIT: Hm, according to http://www.ledtuning.nl/cie.php, 531nm = X:0.162535425 Y:0.80123848. The Rec. 709 HDTV coords for green are X:0.3 Y:0.6 -- not even close. Looks like the 531nm point is waaay up in the pure-green area of the CIE 1931 chromaticity diagram, so I'm not sure why laser-tv.org was so excited about it. It may be pure green but it's not the right green for TV.

Any good? Any good? Of course they are good! They've got freakin' Lasers people!

I found a few threads on AVS about LaserVue. There are very mixed opinions about them. Some poeple love them and others are not impressed. There does seem to be a bit of a problem with the blue laser as mac mentioned, as well as a hotspot in the lower center due a curved lens or mirror that's necessary to achieve it's 10" thickness. Apparently Mitsubishi hasn't made that many of them, even halting production at one point because of a problem, and at this point are not promoting them, although it's rumored that this summer they will come out with new model(s).
Many feel that the market niche for this is 70" plus screen sizes at an affordable price. At 65", there are nice plasmas available for the same or less money that many feel have as good or better picture.
