Guys...I have had a blast playing with and watching CRT. But something today made me realize my reality. Went to RC Willy today to lok at couches....While my wife used the restroom, I strolled to the electronics section and there it was. A 92 inch mitsubishi led. I thought who couls afford this? I then see the price at 4000. Great picture and 1080p looked so lifelike. Is this the death to the home peojector? I am wondering if costs to manufacture these guys are just getting cheaper ans cheaper that size almost does not have a huge separation. Maybe I am just upset I saw it but I still wonder. Perhaps I should looke at it as a challenge to get my CRT that sharp. Now the unit normally sells for 8000 but it is on sale and they need to make room for the 102 inch model. Perhaps I fell in love of was druged by the size.

I could not find where it was LED. They are getting better, but $4000 is still a lot of money. I don't think this is the death of the home theater pj. It will still take awhile to get a lot larger and inexpensive. In contrast, one can buy a RS45 and high power screen for $3500 and have both a bigger screen and better image.

Are you sure it was an LED not a DLP rear projector? I didn't know that Mits made a 92" LED. Anyway...It might look nice in the store...Turn out all the lights and fade to black will look more like fade to gray.
Tonight I had a bunch of people over to watch Super 8. Everybody said WOW that was just like a real theater only the sound was much better...I don't think you would get that response from folks watching a rear projector or even a big ass flat panel.

No question that the ridiculous price drop in the super large flat screens will put them in a lot more homes over a theatre type situation.
I can't wait to see the stats though how many people accidentally smash their screens. 
I also can't wait in 2-5 years when they will start to be thrown away. 
I got in a 46" 2.5 year old Samsung LCD TV. 1080p, although no mention in the specs of anything but 60-Hz refresh. 2 capacitors gone in the power supply, about $,90 in parts, 14 minutes labor. Sold on CL last night for $350. THAT'S A PROFIT!
Did I mention I got 30 more projectors in yesterday? Pix to follow...

How long does the bulb lasts in these DLP RPTVs, are about the same as bulb projectors or somewhat longer?

I have to agree with everyone else, the TV was only 4 thousand dollars 
I am about to hang a CRT and dial in the audio on a friends brand new HT. total cost of the entire room and gear was $6K. That includes framing, doors, electrical, paint, carpet, inspection, + the audio and video system with Premium Quad 22L2 floor standing towers( piano lacquer finish), center, surrounds, Da-lite high-power screen, and Marantz Sr 5006 receiver. NEC PGX was used and cost about $500. with mounting bracket and new moome external HDMI transcoder.
I don't care how sharp it is, to me a 4K$ throw-away TV with 2 to 4 year lifespan is frickin nuts,

It is funny that pjs used to cost more than RPTVs and now it looks like it is the other way around. You can get Mits DLP pj for around $2500.

I have over 12,000 hours on my Sony LCD RPTV. Although i seriously doubt i'm the norm. It's starting to get a bit dim, might pick one up on amazon for 50 bucks. Pretty sure everybody else rocking that model has thrown them in the trash so bulb prices have come down a bit lol.

You have 12,000 hours on ONE lamp, Verge? That may be some sort of record... I've NEVER heard of a UHP lamp running anywhere near that long. You may want to change it before it explodes and takes the optical block with it.

Curt-
That is a nice profit!!! You have something there on the smashed TV thing. My daughter scratched the front of my Plasma with a screwdriver.

Yes they certainly can explode and make a real mess.

My bro inlaw / sister have an LG DLP rear pro with more than 12,000 on the original lamp. I would think this is pretty normal since they are substantially less bright...

Hmm... I see relatively late-model TVs on craigslist all the time with dead bulbs, though. The lamp wattage ratings aren't different, I don't think, like 120-150w vs 250w for a lot of front projectors. Perhaps some models of RPTV use a higher-wattage bulb, but drive them at a lower power rating. I wonder how many die at 3000 hours for every one that lasts 12,000.

Well its anyones guess without looking into it, but i dont think you need 2,500 lumens on a rear pro, when 500 is tons, anything more is just a waste of energy in every sense of the word.
In my experience with SVGA Mitsubishi LCD ( 1,000 lumen and 650:1 ) SVGA Epson LCD ( 1,800 lumen and 500:1, 2,000 lumen and 400:1 ) and XGA Infocus DLP projectors ( 2,000 lumen and 1,000:1, 2,500 lumen and 1,000:1 ), higher lumen rating means nothing to the quality of the picture, which im quite sure you know all too well. And my 700 lumen Sony VPH 1001QM smashes the f*** out of the lot of them if the lights are off. Next best was without a doubt the Mitsubishi, with the 2 Infocus DLPs bringing up the rear with pathetic reds, in order of mega rediculous brightnesses...

That has a hell of alot to do with it yes.

Waiting on the blue polarizer to fail anyway.
