You’ve just tried to turn your projector on and nothing’s happening! Your first thought might be “the bulb has gone”. But actually projector failure can be for a whole number of reasons, ducts get clogged, components overheat, parts can melt. If you want to keep your projector running smoothly you’re going to have to maintain it.
Projector bulbs can last years, they typically last longer then the manufacturers ratings and if you are using it once a week in the church hall then you may see it go on for a decade! So first off, have a think about how often you have used the projector and if you are years off the natural lifespan then you might have to consider whether something else has failed.
If your bulb shows obvious physical signs of damage, for example it exploded, then this is the time that replacing the bulb should be your first port of call. But be aware that there could be a fault with the system that actually caused the blow out in the first place, bear that in mind before you swap in an expensive new bulb.
If there is no obvious sign of bulb damage and it’s still young in its life then replacing the bulb may not help. Depending on the cost of the bulb, it might be worth having an expert look it over.
Look after your Projector
Projectors have to run under tough conditions, long hours and hot conditions. Remember to follow your projector’s maintenance plan, if you manufacturer has offered advice on how to take care of it, how to keep it clean and running efficiently, then put their instructions into action! As a general rule you’ll want to keep it in a cool dust free setting and clean out the vents regularly. Some models have economy modes that will preserve the lifespan further still.
In most cases, the cheaper consumer home projectors are designed to outlive their warranty and not always much longer. Going for a branded product and avoiding the dirt cheap imported models should give a better experience in the long run.
