Replacement Parts for Projectors

Get a deal on replacement home theater projector components

Home theater projectors deliver an entertainment experience that simply can't be beat, but over time, the working parts in these units will wear out. The two most common replacement parts for projectors are bulbs and lamps; many consumers confuse projector bulbs and lamps, thinking the two are interchangeable when they are, in fact, not quite the same thing. The bulb is a single component of the lamp system, and can be replaced independently if it's the only part causing problems.

Replacement Lamps vs. Replacement Projector Bulbs

Projector lamps produce light internally, using small but strong electrical discharge components, and in a home theater projector, the lamp accounts for the entire light production process, including the generation of the electrical impulse. The bulb is only one part of the lamp, which converts the incoming electrical discharge into light. Think of your projector system as being the same as your bedside lamp; if the bulb burns out, you don't need to replace the whole lamp -- you just need to get a new bulb. On the other hand, if the lamp itself isn't working, a new bulb won't do you any good.

The first thing you should do if your projector stops working is refer to your owner's manual, or contact the manufacturer to ask how to troubleshoot the problem correctly. You need to determine whether you need to replace the entire lamp or just the bulb, and the proper method for doing so differs from manufacturer to manufacturer and model to model.

Once you've determined which component needs replacing, there are a few other important tips to keep in mind. First, remember that not all lamps and not all bulbs are compatible with all projector systems. You need to make sure that the replacement bulb for a projector, or the replacement lamp, will work with your system. Your safest bet is to choose a replacement part made by the same manufacturer as your projector.

Keep in mind that projector bulbs and projector lamps are far more expensive than typical lamps and light bulbs. You should be prepared to spend several hundred dollars on these replacement parts, as they rely on intricate and precise technology which is expensive to manufacture.
