How often you'll change the lamp in your LCD projector has a lot to do with how often you use the projector, and how old your unit is. The bulb typically lasts a long time (anywhere from 1000-2000 hours of use), which means you won't change the bulb very often. However, there's a lot more to this than replacing a 60-watt bulb -- the process is tricky and replacement bulbs are pricey.
Older model projectors (prior to the year 2000) typically have a lamp life expectancy of around 1,000 hours, while newer projectors may feature lamps that are expected to last for 2,000 hours or more. Check the technical specs on your specific projector to find out your expected lamp life, and if you're getting close to the max, secure an extra bulb so you won't be caught unprepared. Some projectors feature an eco-mode, which sacrifices a small amount of brightness in exchange for a much longer bulb life.
Replacement lamps typically cost between 0 and 0, depending on your specific model. The average cost of a replacement bulb is around 0. If you choose to have a professional replace the bulb, that service will likely run you another 0 or so. Be sure to check your warranty information on your specific projector unit - depending on your specific unit and warranty, you might void the manufacturer's warranty if you replace the lamp yourself.
If you prefer to change the bulb yourself, here are some simple tips that explain how to do just that. Be sure to handle all parts of your projector (especially the bulb) with extreme care and a gentle touch.
Step 1: Remove the access panel located at the rear of your LCD projector. Usually, just one screw is holding the panel in place.
Step 2: Loosen or remove the screws located on either side of the base of the lamp. If the bulb doesn't come out easily (with no more than gentle tugging), loosen the surrounding screws and give it another try.
Step 3: IMPORTANT: Remove the bulb without touching it, as it may be hot and is extremely fragile. It's a good idea to protect the bulb with a soft cloth during removal (rather than using your bare hands).
Step 4: Replace the new bulb, ensuring the plug is securely in place. Be sure to use great care while replacing the screws that were loosened in step 2.
Step 5: Replace the access panel and screw in the single screw holding the panel in place. You cannot test the projector until this panel has been appropriately replaced.
Step 6: Now turn your LCD projector on to test its function. If the projector doesn't function properly, you'll need to repeat steps 4, 5 and 6.
NOTE: When replacing the new bulb, wiggle it ever so gently to get it into place - do not force the bulb, as this can cause it to break or can damage the delicate connections inside your unit.
Of course, if you'd rather not worry about blowing out one of these expensive lamps or damaging your LCD projector, why not rent instead?
