Step 2Install New Bulbs

Install New Bulbs
First, unplug the projector and open the top cover. On every projector I've seen, there is a little button you have to push in on the side of the writing surface. Push this button in and the whole top cover (including the writing surface) will lift off.

You will see the light bulb chamber right in the middle. Lift the lens covering the light bulb chamber and remove whatever bulbs are in there. Remember, to get a bright enough light, we are going to replace the stock bulbs with our new ones.

Carefully insert the new bulbs where the old ones were. Do not touch the bulbs with your bare hands or you will shorten their lifespan. Usually the bulbs will come in some kind of packing material that can be used to help insert the new bulbs without touching them directly.

Close the cover to the bulb chamber, and you're all set.
