Thanks for your replies everybody, in particular masterying01.
This morning my wife and I were discussing which set to buy, and after I explained about bulb replacxement, potential rainbow effect, my wife wants us to get the Sony KDS55A2000. It's about $600 more than the Toshiba and Samsung, but my wife pointed out that if we have to replace bulbs at $250+ a pop, there really *is* no difference in price. It's hard to argue with logic like that.
masterying01- have you had any experience with the Sony? Has anyone else?
Thanks again for all your help.
You'll not be disappointed. It's the best HD RP TV (look at all the acronyms) on the market. I used to sell them all, was able to look at and test them all with SD and HD programming, and I bought the Sony.
When I bought mine I also bought the bulb. It will sit on a shelf until needed. This way, when it finally dies, I won't have to wait for a replacement. Pop it in and order another.
I think I made a mistake in my previous post. I thought the Sony KDS55A2000 used LEDs, not a bulb, but I was wrong. There goes my wife's argument in favor of the Sony.
with the exception of CRT based RP. There is in development a laser based light engine. Supposed to be available this year. As for the Sony, read another comment here:

The technology is changing so fast. The cost of LEDs is dropping fast, the brightness is going up. In a year or two all the lamps will be LED, long life low power usage and NO color wheel!
To get around the lamp issue look at LCD direct view or plasma sets. John
I keep reading statements that LEDS are being developed that will replace the current crop of DLP bulbs. This is probably a really stupid question but I am wondering if these new LED bulbs will be able to be used as the light source in the same TVs that currently use the DLP bulbs.
Thanks for any insight you can give me.
Time will about that.
JVC and Sony do not use a color wheel in their LCoS sets, but they do have a lamp. John
I work on these tv's. We have seen the DLP color wheel crack, split, and otherwise cease function. It's not too hard to replace...can even be done in the home. Unfortunately, some manufacturers are not supplying the color wheel. They will only give the "Engine", which is the whole unit associated with the light...and it is VERY expensive. No, these color wheels are not generic, and there are at least 2 types now. There are also all kinds of other problems with the DLP tv also. The DLP and the plasma tv will both go the way of the 8 track. THe future is with the LED, LCD, and even further out...the thin film. Wouldn't take a DLP as a gift.
Funny a year ago I bought a Toshiba 72" d.l.p beast it was at that time state of the art hottest t.v. on the market Well after a year its now a piece of junk and all you pros tell me what a fool I was to buy it. Sorry but the picture quality still looks as good as anything on the market and hooked up to my New Sony blue- ray player the picture is out of this world I have had no problems at all and could care less about changing a lamp every 3 years.In closing I remember going back 40 years you had to be a t.v. repairman just to keep those t.v.s running . testing tubes every month or so, pulling the tuner out every year to clean the tuner noe days folks want a t.v that will last a thousand years of trouble free service TALK ABOUT SPOILED HA HA stewee
Last year I had to compare LCD and DLP projectors for the local library. What I found at the time is that DLP have better blacks but because consumer DLP projectors only have one chip and hence a color wheel, there is a troublesome artifact. You will perceive a color breakup on fast moving objects and end credits. The same thing happens if you move you head or eyes and some people have actually claimed that the effect caused headaches.
Stay tuned SONY has a solution in their new technology.
I also have been in a quandary over similar issues. The color wheel failing or spending a noisy squeeky lifetime creating the theatre room from hell item, overshadowed by concerns with the light source. Escalation of misgivings over cost and availability of light source had put the motivation to expend nearly $3,000.00 on a 3 year product that would apparently not last out the warranty period trouble free on the back burner.
Other major concern was the 850W to feed the mercury bulb of a worthy display and the probable need to have an electrician out to ensure that that sort of power was being safely sent to that area.
Recently we had viewed a laser based product. I am sure we will be holding out a bit longer with the 35 inch Panasonic old fashioned fat giant cathode monster eye in deference to the laser products which are scheduled for sales in time for the '07 games season.
BUY THE PLASMA.
With some Sony models, bulb life is definitely not all you need to worry about!
There's also the green blob problem. For more info, Google "Sony green blob" (without the quotes).
I don't understand why anyone would buy a DLP or LCD rear projection tv when you know the bulbs don't last very long at all. At at $250.00 - $400.00 a pop thats crazy. I mean look at plasmas, they last 60,000 hours to half brightness. Thats like 8 hours a day for 20 years and really who has a tv thats 20 years old now so the odds that you have that plasma 20 years from now is pretty slim. Don't listen to people telling you to spend huge amounts of money on a 1080p set right now. Unless you get HD-DVD or Blu Ray your not going to really get the full affect that that tv can deliver(and untill that war is over i'm sticking with dvd). I've talked to guys that work for Comcast and they said we're looking at about 4 to 5 more years before 1080p is broadcast on cable. With all the analog channels still out there they simply don't have the bandwidth to support digital, analog and high speed internet on the same line. I bought a 42" Philips Ambilight plasma from Sears for 1299.00. The tv looks great and didn't cost a fortune, plus i don't have to worry about replacing a bulb in a year or two. Good luck finding the tv you want!!!
I always have to defend my d.l.p. monster lamps, color wheels, and fans, But after 14 months of trouble free service and stunning picture quality Ial stick with what I have thanks Lamp still blazing brite $200 replacement cost and 2 minutes to replace it I know where you guys are coming from I guess I just got a cherry ha ha also Many many friends and family have seen this beast and no one has sceen the rainbow effect I agree newer sets are more trouble free I can care less Casino Royal on blue ray POPS on my junk ha ha. remembering the golden age of t.v you had to be a t.v. repairman just to own one. So $200 means nothing to me stewe
