Projector bulbs gradually fade (dim in brightness) as they age, or get used up. Eventually, like any bulb, the filament will burn out and you'll have no picture.

Perhaps on an overhead projector. :p

Most DLP units use a metal halide lamp which falls under high intensity discharge. (HID)

Some facts about MH lamps:

You can damage the lamp if you move it while running, or change its position while running and/or hot from operation. I don't want to get into the technical facts of what causes this, but a lot of people neglect this fact and wonder why their lamp dies very quickly! This really applies to PJ's as they are frequently picked up and moved while hot or running. (DO NOT DO THIS!) If you need to move it and cannot shut down - cool off, by all means move it slowly without tilting or turning it over! That is very bad for the bulb. Excessive vibration is also bad when running so this is something to consider if your movie room has a matrix of 144 18" woofers connected to a pole pig, ahem amplifier. :)

The colour temperature of the emission will often shift as the lamp ages. Some more than others. Better sets can adjust for this and some cannot adjust well at all and the whites just look plain funky. The shift is always warmer. (at least on Earth it is!)

The lamps do drop off in output as they age but the transition is graceful providing you don't abuse the lamp. Lamps do suddenly fail and that's the nature of the beast. One thing is certain: if you abuse it , the LAMP WILL FAIL and SOON.

Cheers!

If you only make $14K a year and want to leave a TV on for 16 hours a day, maybe you should get out of the house and get a better job???

Thanks you, the television is going back! Nothing will make me change my mind.Its supposed to arive at 11, but i wont accept it.
I don't think the goal of people responding to this thread is to make you change your mind about returning the TV. I think the main point here that people are trying to drive home is...you're an idiot. It's a very simple point.

Everything is done.

Television got returned.Got full refund.

Bought instead a HDTV CRT Rear protection 46" Hitachi 46F510

Im receiving it tomorrow.

Yes it was my mistake of accepting that deal.The store was kind enough to take it back.The television never arrive to my home anyway, so it cost them nothing in shipping.I call them before the store ship it so it remain in the store.

It was a DEMONSTRATION television.Only GOD know how many hours the bulb was used already( was this television in display for 6 month already? At 12 hours a day? )I dunno.But i got the feeling i would have to replace the freaking bulb in less than 6 month.

Hey i took my decision.I decide to get this CRT HDTV instead of this DLP at half price.Ill die with my decision there.I bought the CRT at another store and this store dont accept refund.

Just a second.How the hell can u consider me stupid???

I just paid 2k on a television and every freaking year ( YES i am someone who watch, pardon me, who keep his television open 16 hours a day ) i have to pay 200-300 dollars to get the bulb replace???

I just hardly SAVED this 2k to buy one of these television and i dont have the budget to invest 300 more per year to get the stupid bulb replace.For god sake i am not making 50k a year but 14k a year....

Bulb DIE at around 5k hours( compagny claim 8k hours )Do the math 5k / 16 = 312 days

I knew by getting a discount from 3200 CAN to 1800, there was a catch.And it was that.

Tomorrow, the store is getting back the television.

Too bad, it was the nicest looking picture i ever saw...Log live my old CRT tube 36' trinitron :)
When u spend 2k on something.You expect that to give you 5y + of pleasure.Not 1....

This is like bitching and whining that you bought a BMW and can't afford to maintain it you fvcking moron. I'm typing this out on a DLP television myself, which I just bought before xmas, so yes, I CAN and will speak on this topic.

Perhaps you should have bought the extended warranty if you're so damn paranoid. Get over it.

PS: What jacked up school of match did you attend to decide, from your extremely extensive experience that builbs *will* die "at around 5k hours"?

haha, lovely.

You returned a kickass tv for an IMO crappy (in comparison) and outdated rear projection CRT?

Hell if your doing CRT, at least do a real CRT to get some good blacks.... I for one can't stand those RP CRT's....

LOL @ thread.

I've worked with some photography bulbs that produce practically no glare on object they are lighting up... but the bulbs only last like 3 or 5 hours or something insanely short like that. And cost $20 a pop.

hahaha...o m g...i nominate the OP for most illogical of the year, and we're only on the second month! A CRT rear projection is worse, imo, than a DLP set.

First off, a CRT projection needs constant convergence alignments. If the user menu doesn't have fine engouh adjustments, you're gonna have to mess around with the service menu; messing in the service menu can often void your warranty.

CRT projection tubes are much more expensive to replace than a DLP light bulb.

and the list could go on and on.

wow. just wow.

You better take them both back and buy a book of "PLURALS" and read it about 16 hours a day and save the rest for an "internal bulb replacement" for yourself and no you can't do it yourself. Actually why do you want this set if you have a "crt 36' Trinitron" ? A 36 foot Trinitron should be large enough for almost anyone.
Perhaps you are looking at it thru the wrong end of your telescope again.

I work at Walgreens. There are a few things that really get under my skin:

1. A customer wanting us to refund the difference when something they bought three months ago happened to go on sale. (We do it, and I'll explain below.)
2. A customer who expects us to stop helping other customers to help them.
3. A customer who shops past closing time, refusing the help I offer them when they're looking for something. After searching for a good 20 minutes after closing, they ask where it is, only to find it on the shelf right behind them.
4. A customer who demands a discount on late film when the power goes out
5. A manager who micromanages an employee who's been with the company longer than they have
6. A customer who wants to return something that's heavily used and past its usable life.

My favorite was when a customer returned a beach chair on July 5th after using it to watch fireworks out at Cocoa Beach, but there are plenty of other examples, such as a mostly-empty bottle of pills that "upsets her stomach" or a banged and scratched up toy that "quit working right after they bought it". Fvcking thieves will rot.

Fvcks like these raise retail prices for everyone. Retailers are put into the position of catering to them because all their competitors have to kiss ass to them as well to try to win loyalty.
