    FIRE!!!

    Cleaning a projector yesterday in a primary school, blowing the dust off with a can of air next thing that appears is a large flame out the side of it. luckily it went out straight away, now I have been asked to see if I can get this projector repaired. hmmmmmmmmmmm.

    Anyone got any Idea how to repair a burnt projector?

    Yes, but it'll cost about £350 and will involve fitting a new case.

    i did the same thing once. was in a rush to clean the filters and left the projector on, blew the canister of air into a filter and it must have shot out a jet out it as liquid as i heard a loud pop and then could smell my eyebrows burning

    left a nice large hole in the filter but the projector itself was fine luckily

    This is caused by the propellants (usually propane and butane) in the can of air burning in the projector. I'm guessing the projector was either switched on or had only just been turned off?

    Is the projector actually showing any signs of damage? If not, it is unlikely it was damaged as the air/propane/butane burn so quickly there was unlikely to be any build up of heat enough to do any damage.

    That's ace! I'm not tempted to try it though, but the propellant in air dusters is flammable (says here 13% by mass flammable content), and some projectors do get mega hot...

    Thats one of the reasons why they state to leave them turned off for a preiod of time before changing the bulb to allow the high temperatures to drop.

    I use a giottos rocket blower for all of my projector cleaning no chance of igniting propellants then.

    I don't care what the situation is, there is no excuse for using the word sense around 6 year olds. you should be ashamed of yourself
