Keep Your Projector Running SmoothlyTake these simple measures to avoid projector disaster.by Rich Malloy
You’re all set to give a crucial presentation. Your gear is carefully laid out and connected. Your laptop booted up uneventfully, and your PowerPoint file is sitting there on the desktop waiting to be shown. A few minutes before showtime, you press the power button on the projector as you’ve done so many times before. Nothing. Maybe you didn’t press it firmly enough. You press it again. Harder. Even harder still. You check the AC cable and try a different outlet. You’re due up any second now, and you suddenly realize that your projector has somehow died. What should you do?
Preventive TipsOf course, the best way to handle a serious equipment meltdown is to avoid it altogether. Yes, the technology gods can be ruthless when an important presentation is on the line, but they seem to be kindest to those who respect them. Keep in mind that your equipment will fail eventually. The smart presenter is always prepared.
Keep Spare Parts HandyAccording to manufacturers, a typical projector lamp will last an average of 2,000 hours. That’s the equivalent of a two-hour presentation every business day for four years. But that number is merely an average; half will fail before that. In other words, there’s a reason most lamps are under warranty for only 90 days. Personally, I’ve had two projector lamps fail on me, one that died sometime around the predicted 2,000-hour mark as expected, and the second at far less than 100. A well-cushioned replacement lamp (ranging from $300 to $450) is not the only thing you need. Also bring spare batteries for your remote control, an extra AC extension cord, and a screwdriver to replace the lamp.
Learn How to Replace Lamps
How many presenters does it take to replace a projector lamp? The process is harder than you might think, and certainly more difficult than it should be. Several small screws may have to be carefully removed and replaced. Also, the old lamp could be dangerously hot, and you must be careful not to touch certain parts of the new lamp. And if the above weren’t daunting enough, keep in mind that replacing a lamp in front of a large, increasingly impatient audience won’t make things any easier. Get a head start by doing a dry-run lamp replacement in the privacy of your office, so you’ll have a better idea of what’s involved.
Keep an Eye on the Lamp “Odometer”
Usually there is no warning when a lamp fails, but there may be a clue. Most projectors have an odometer of sorts--a log of how many hours its lamp has been operating. Check this semiannually, such as whenever you change the clocks, so that you have some idea of when the lamp may expire. (We also suggest keeping track of your warranty, as electronic devices seem to have an uncanny tendency to fail just after that agreement expires.)
