I agree about the intern thing. Not my choice. Not wise on their part either. I have a very supportive superintendant. He is new to the district which is a great time to innovate change. I plan on writing grants this year. (Looks like it will be necessary.) Once I get my facts straight and deal with IT and then if I have to: meet w my super I can start to get things done. I found the specs on the projector at one lab.( Custodian is my bud and was still there) Not the one I posted about. In this lab the old tech teacher left a note saying the bulb needed to be replaced. It is a Dukane Liquid Crystal Projector 8755B. There is no remote to be found and she used a stick to power on and off. I will not do that. It could harm the equipment. So.. I haven't been able to check the quality of image projection thus far but I have a feeling it isn't going to be good. I refuse to power the projector on and off with a stick and standing on a chair to reach the projector itself is out of the question. It does not make any sense at all. See what you can find on that Dukane model if you possibly can. I will give you the specs on the other one asap. Also, I have a feeling it WAS a simple cable connection to split. Almost positive. I wasn't in the lab at the time ironically. This is going to be a long year.

That's an ancient projector, by technology standards. This link has the specs as well as a link to download the users manual. The lamp is somewhere around $240 - $260 for an OEM lamp.

I would not spend ANY money on repairs if the projector fails, the cost would be as much as a new projector. I WOULD, however, get a replacement remote. Hitting with a stick is stupid and may cause problems, such as knocking it out of alignment if too aggressive and the mount is not real secure.

Not sure if I replied to your last response! So stressed out over these projectors not working. I am only seeing the post and all responses when I click reply to topic also. The other lab has the projector Optoma EP 732. (Boy do I need my glasses) Checked the back of the hard drive. Yup. One in two out. Basic Cables. A Sherwood Stereo is back there too which I guess would be good for sound but the plastic piping connecting to the panel is annoying. Can't find its remote either. Thanks for links on the other projector. Haven't been able to do much in either lab with the students. The problem also is this.... I just have to wait until they get back to me about the bulb or decide to come out and check it. At least now I will know what the projectors really need and be able to discuss it when them. Please tell me what you know about the Optoma and there is also Mimio software for the screen and the screen panel but the other teachers didn't use it. I think it makes the screen more interactive I am hoping. Do you know anything about using Mimio with the screen?

This is one thing I always stress to my friends and family when they ask me questions...Google is your friend.

Here is a site that has the manual for the Optoma...

http://www.manualowl.com/p/Optoma/EP732/Manual/116410

I don't know anything about Mimio, but guess what...

http://www.mimio.dymo.com/

And the "splitter", they MUST use something like this when sending a video signal to multiple displays...

http://shop.texasmediasystems.com/Extron-P2-DA2xi-Two-Output-VGA-Distribution-Amplifier_p_1054.html

There are cheaper units, a lot of them are junk. But anytime you "SPLIT" a video signal, the level available to drive the display is cut dramatically. You may well see the image improve if the splitter were removed and the output went straight to the projector.

Your use(or misuse)of terminology concerns me. You said cables coming out of the hard drive. I hope you meant "computer" or "computer tower" as the hard drive is an INTERNAL component that would not have monitor cables coming from it.

And then there is the comment about "plastic piping" and "panel". I have no idea what you're talking about there. It helps us help you when the descriptions are accurate, because if we have to guess, we could be way off.

By the way, both projectors are at least 6 years old and should be replaced with new projectors when feasible. You do not want to spend a dime on any repairs for those should it come up.

Sorry I am so stressed out. I do not know why I put hard drive in that statement. That is not what I meant to say. My brain sometimes works faster than what I type. My Dad is a former programmer and "think thank' guy. My brother started the first digital law firm in this state. How do you think they feel? lol They get frustrated as well bc they are more advanced than me. I must always remind them... Pretend like you don't know and teach me. Such as: imagine yourself walking into a classroom of 20 kindergarten children. The parents are at the door. They all want and need your attention. Children and parents alike. You must give them everything you have for the entire day to give them the best education possible. They go to computers. They see their teacher ( Now me) Other teacher is my mentee. They can't log on bc server is down. No image bc bulb is.... Pleae be patient. I am learning. You sound just like my Dad or brother.
I do not know your "language" yet and you do not know mine. Children are important here. As far as my misuse of terms: please forgive me. If you told me a child was 'very low ' I would tell you that is not the correct language. You should say this child is struggling academically with such peers. But.. this is my language... not yours.
I hope I have managed to make a point and not offend you. I am also hoping you are starting to see how different the two worlds are. One is the computer and all that entails. One is human. We teachers may be replaced one day. We discuss it all the time. So... if you want to continue helping me I would appreciate it. If you can't tolerate my level of novice I understand.
