    Projector not projecting!!

    Are you ready for another installment of Little-Miss' stupid questions?!

    Right, a projector that hasnt long had its bulb changed "has blown" according to the staff. Apparently it went dim and then went off, but if i put a piece of paper in front of the projector there is still an image...basically like its not reaching the board....

    Can the throw on a projector just stop throwing?!

    If the bulb is on it's last legs it could be so dim that it can't project that far which is why you can see it on a piece of paper in front of the lens.

    How many hours has the projector/builb been in use for?

    Do you have another one with the same bulb you can test with?

    IFAIK the bulb is the throw on the projector

    Could be worth checking if some one has 'blanked' the projector. 9/10 there is a 'blank' button on the remote.

    Otherwhys I'd take the bulb out, you'll soon see if it's blown.

    The lamps are arcs, so if it's blown you'll get nothing at all. Check somebody hasn't fiddled with the brightness and contrast controls, switched on blanking, etc.

    Lamp alignment would also cause this problem, but you shouldn't be able to adjust that - it's factory set.

    You could try resetting the projector to factory settings (if you can see enough to do that), will clear any brightness issues. If possible test with another bulb from another working projector. If not get a new bulb as the old one (albeit not terribly old from the sounds of it) is a duff one. Check with supplier/manufacturer to make sure projector isn't covered by a bulb warranty before ordering!!

    Is it a projector if its not projecting?
    Have you cleaned the filters of late? As if it overheats its possible that it could blow a newish bulb?

    Also check if there is a reset function, normally key presses. We have recently found that some projectors (Mitsubushi) we have after changing the bulb and resetting the menu timer still act as if blown unless you carry out a 'reset' by holding various buttons down & turning the projector on. May be something like that.

    You should add a poll. My vote goes to "Teacher has ignored the large "please clean filter" warning for days/weeks".

    Ok, went back to check during break. Filters pretty clean, not clogged up. Now projector just turns itself straight back off again.

    Thinking bulb....which is a bit pants cus it's only had a new one in the last few months...they're so stupidly expensive to replace....wonder if its worth checking out a new projector with 3 years warranty....

    Isn't the bulb normally excluded from the extra warranty?

    Not necessarily. Most of the Epson education projectors include the lamp in the 3 year warranty. I know other manufacturers do this as well.

    Throwing distance of the projector is determined by the lens, hence short-throw, ultra-short throw, and long-throw. Some high end ones can have different lenses attached to modify the throwing distance

    If you have an identical projector somewhere else I'd swap the lamps to see if the problem follows the lamp.

    Otherwise, any of your kids bright enough to program a PSP for use as a remote control? Some of ours did it and were turning the projector off in the middle of each lesson.

    The projector isn't on 'No Show' is it?

    Look on the remote for a 'No Show'/'Mute' or siilar button.

    If it IS the bulb and it really has only lasted a few months - could be worth an argument with the seller - it certainly shouldn't have gone that quickly.
    IMHO the older the projector, the shorter time the bulb lasts - don't know why!
