I got a Sharp video projector for free but the lamp is dead. Well, not so free: the lamp costs $550 and up to replace.

So I either have a free white elephant that sits on a shelf useless or a I need a pricey lamp to get it running. I was hoping to use it for my scraping classes.

Is there a low cast work around for video projection lamp? I was thinking of a quartz halogen lamp and accepting the yellow color and its own power supply but I suppose there's a reason why these gadgets have to have a pricy and exotic lamp to make them work.

Help.

You can buy lower cost replacements on the bay - but I don't think you could get much brightness out of QH lamp. The problem is the size of the arc in the original lamp. It is very small so the optics can be designed to be efficient and handle the three colors needed for projection. The filament on a QH is just too large. Further, the spectrum of the QH is wrong for the application. I would either buy a cheaper e-bay bulb or a cheap new projector. Probably not much more than your bulb.

I had an infocus 720p projector. Tried and off brand lamp and did not have good results at all. Hard starting.

Which model do you have? You can buy a refurb Infocus Screenplay 5000, 1100 Lumens, 1280x720 3LCD native HD, all sorts of inputs, for about $550.

I ended up buying a Panasonic AU-1000U 1080P projector. I love it! 1920x1080 res on a 108" screen! Halo 3 looks so good...

The lamps in the machines are high intensity discharge. Cant substitute anything since the light needs to be a specific beam shape. Plus the projector itself needs to have a signal from the lamps ballast circuit to signal all good. There were a couple LCD projectors that used a tungsten lamp but they were not very bright when new and you had to use them in a pitch black room.

i work in the AV business and what model do you have i may have a good useable bulb sitting around. No there is no work around that can get you the colors that are needed for a correct picture.

Aw heck!! I was hoping... Oh well. Looks like if I want a projector I have to step up and buy one. Thanks you responders.

Anyone want a projector cheap?

As in box you mean CRT? My parents still have the toshiba 27" I bought them years ago.

Projectors are great but not for everyone. You need to have a decently light controlled room for one.

actualy the new projectors can be used in well lit rooms i have a 3500 lumen projector and i use it out side to watch moves in dusk for the neighborhood.
I still need to know what projector you have and i may have a bulb for you.

Yeah, but a 3500 lumen projector at 720 or 1080 is way past the $1600 I paid for my Pani!

You know what, it is depressing enough getting my arse whupped all over by 12 year olds on my 59" screen playing Halo3, some of those little butts have some nasty little mouths too:p

Jason, the unit is a Sharp Notevision XG-P10XU. If you have a bulb with a few miles left on it for peanuts, I will be most grateful.

Sorry Forrest i have only lamps for newer proj. if it has a bulb in it try this

unplug
press down arrow, right arrow, and enter at same time then turn on it should reset the the lamp hours wich will let you turn the projector on. Lamps are set at 2000 hours and ones it hit it it shuts the proj off and it can not be turned on untill you reset lamp hours. I have seen lamps go for 4000 hours they just get dimmer and dimmer.
