LCD Projector Maintenance: How to Change the Light Bulb

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 generally lasts a long time (1000-2000 hours of use), which means you won’t be changing the bulb very often. However, there’s a lot more to this than replacing a 60-watt bulb: the process is complicated, and replacement bulbs are expensive.

Older model (pre-2000) projectors typically have an expected lamp life of around 1,000 hours, while newer projectors may have lamps that are expected to last 2,000 hours or more. Check the tech specs for your specific projector for expected lamp life, and if you’re getting close to the max, get an extra bulb so you’re not caught off guard. Some projectors feature an Eco mode, which sacrifices a small amount of brightness in exchange for a much longer lifespan.

Replacement bulbs typically cost between $250 and $600, depending on the specific model. The average cost of a replacement bulb is around $340. If you choose to have the bulb replaced by a professional, that service will likely cost you another $100 or so. Be sure to check the warranty information on your specific projector unit; Depending on your specific unit and warranty, you may void your manufacturer’s warranty if you replace the lamp yourself.

If you prefer to change the bulb yourself, here are some simple tips on how to do it. Be sure to handle all parts of your projector (especially the bulb) with the utmost care and a gentle touch.

Step 1: Remove the access panel located on the back of your LCD projector. Usually just one screw holds the panel in place.

Step 2 – Loosen or remove the screws located on both sides of the lamp base. If the bulb does not come out easily (just a gentle pull), loosen the screws around it and try again.

Step 3: IMPORTANT: Remove the bulb without touching it, as it may be hot and extremely fragile. It’s a good idea to shield the bulb with a soft cloth during removal (rather than using your bare hands).

Step 4 – Replace the new bulb, making sure the socket is seated correctly. Be sure to be very careful when replacing the screws that were loosened in step 2.

Step 5 – Replace the access panel and screw in the single screw that holds the panel in place. You cannot test the projector until this panel has been successfully replaced.

Step 6 Now turn on your LCD projector to test its function. If the projector does not work properly, you will need to repeat steps 4, 5 and 6.

NOTE: When replacing the new bulb, rock it very gently to snap it into place; do not force the bulb as this may cause it to break or may damage the delicate connections inside your unit.

Of course, if you’d rather not worry about turning off one of these expensive lamps or damaging your LCD projector, why not rent one?
