Shattered bulb inside SMART UF45 projector

[mr_anthony]

At my public school we had lamp bulb for a Smart UF45 projector burn out, pop and shatter within the unit, fortunately most of the glass stayed within the lamp housing. The projector hangs upside down and faces to the rear which leaves the access panel facing down and easy to service with a ladder. Following instructions downloaded from Smart's website I removed the old lamp, didn't originally notice any pieces of glass when I shined my phone camera's light up there. After inserting the replacement bulb and ensuring all the screws were tight, plugging it back in, the fan powers on but after 5ish minutes with just the fan and no picture, I get 5 beeps and right lights (blinking lamp, solid power.) I double check everything two or three times with the same results before I call my boss. My boss recommends double checking the access panels, I do that to also no success. Upon my bosses instruction I remove the projector unit from the boom and bring it back to my desk/workbench which is when my boss notices that one of the screws were loose and there were tiny shards of glass I did not see before.

Since this is the only type of this projector we have and since the media center specialist uses it for almost every class period, I must get it cleaned and working asap, therefore what is the best way to clean tiny slivers of broken glass from the inside of the projector when you don't have a vacuum and is there anything I should be aware of that could be causing the projector reject the lamp? Also could I have done any damage by having the loose mounting screw which I originally thought was tight?

Thank you in advance!

You need some safety eye glasses to protect yourself from any small shards of glass and you either need to suck or blow the glass out - if you don't have anything to do this then you will need to purchase something.

 

We use this air duster for this sort of thing: Metro Vacuum ED500 DataVac 500-Watt, 0.75-HP Electric Duster | Staples®

 

You could try shaking it over a bin bag to catch any loose glass but I wouldn't recommend that option as you may damage the projector.

Have you reset the lamp hours on the projector?

Even with a new lamp these wont operate until this has been changed. With the projector in stand by mode, hold down the up arrow for 10 seconds until a beep is heard. Then hold down the down arrow for 10 seconds until a lounder beep is heard. At that point start the projector up as normal.

 

This can be tested ont eh bench with just a power cable and a remote to turn it on.

I have about 15-20 of these projectors, I let all of lamps die as best I can and still turn on fine after a lamp change.

 

PM me if you need more help.

Thank you for your reply, I will check with my boss to see if we have something like that on hand.

Thank you for your reply, yes during one of my attempts I did do the reset as per Smarts website. May be it was just a loose screw, I forgot the remote in the media center so I'll stop over today and pick it up and try it again.

 

I'll update you on my progress later today.

 

Thank you again.

Sorry everybody, kinda dropped the ball on this one.

 

Final update: it turns out the spare bulb we had might have been defective/used. After getting a brand new/refurbished lamp in, the projector came to life.
