    Projector lifetime

    How long do you expect projectors to last? We have around 40 4 year old NEC VT58's and we are getting gradually more reports that they are feint. We've tried new bulbs and cleaning the muck off the whiteboards but some of them are just feint. Is this an expected end of life condition? Can we do anything about it? Do other makes last longer?

    Thanks

    We're starting to replace our worst VT58s, the NP110 or NP115 will drop straight in.

    You'll find the panels inside the projectors are deteriating and this is what is causing your problems. I'd start looking at a rolling program to swap them out, keep back the better ones for when ones still in service pop.

    When was this projector last serviced? How many hrs doers it have on it?
    I would expect projectors that are serveced to last around 12 to 15,000 hrs.
    this is ONLY if lamps have not been over run, by that i mean not run beyond their normal hrs, you should idealy change your lamps at around 2500 hrs, using beyond this will stress the ballest unit and give progressively dimmer output with each lamp change.
