Thank you for telling me about the Casio. Any idea on the price of one? There are certain things to consider about working in a public school. If I were to go and get my own projector then the district would most likely never replace that bulb or update any of our ceiling mounted projectors. To them that means problem solved. We are having trouble with many of them not just the ones I am speaking of here. The district purchsed these and installed them. They did not ask the teachers what we thought or for input. It really is their responsiblity to keep the technology current and operable.

I do not know who gave her that quote of $900. I do know that they do not contract out specialists to install these bulbs. I believe the head of maintenance has been doing most of this.( Do not quote me on that but almost positive). They put in Smartboards in many classrooms and teachers were upset bc they were off center or not put in a logical place. This is all getting very frustrating to me. One teacher was recently told that her projector which was put in a year ago (An Epson) not sure specs had overheated and they accused her of leaving it on for days and not turning it off. She did turn the projector off each day.

The Casios have pricing available online. I believe about $1,200.

They are more expensive, most likely than what you have now, but they have ZERO maintenance costs. No lamps to replace over the life of the projector. Much like a LCD TV, you put it up, then can forget about it forever.

The reality is that schools often purchase projectors by looking at the bottom line price instead of actually buying a product that has the lowest cost of ownership. Not only is the Casio cheaper to maintain, by far, it is more reliable, which means more teacher usage of the product and greater teaching reliability. It also draws less power than many comparible traditional projectors.

But, when you figure the school board likely won't just ship you a lamp to install, and that many teachers won't climb up on a ladder to remove a projector to reinstall a new lamp, then you start to understand that someone else has to be paid to do that for you. So, the price goes way up. Especially for ONE lamp. The lamp is $300 (or more) and the labor likely has a 4 hour minimum. Of course the person won't be allowed onto school grounds DURING school hours, so you also are paying for after hours time for the technician.

Shoot, if you are in the DC area, I could get you a much better quote!

I have not posted bc I have been making do with no screen and no bulbs. Finally,some of the teachers wanted me to do powerpoint with the students. I told them I would love to but it would be almost impossible to show them how to create a presentation without the screen to teach from. My principal said he will now look into ordering the bulb. I went into the lab today and the projector was gone from the ceiling. He said it had so much dust on the bulb and that is why it most likely wasn't working. Not sure about that but at least there is progress!! I told him to please order a remote as well.

Nope, dust does not make a bulb go bad or fail. Make sure (if you can) that he orders an OEM, not a cheaper "generic" of "compatible". He'll be wasting money.

First, if there is so much dust in the projector, the image on the screen is very dim. You can clean the projector, all from inside to outside, every part of the projector.
Second, if your projector had been working for years, maybe about 5-6 years, the inside lens, refraction glasses and filter are all old for work. In this case, you will change it for a new projector.
Third, if the lamp is working over 1000 hours or more, it reached the end of this lamp life. You need to replace a new lamp.

Please check.

Regards and Thanks.
