How to Relamp a Projector
Projector lamps are the most critical component in how a projected image looks. A fresh lamp with low hours will give bright crisp detail and vivid color on the projection surface. A lamp that has been used many hours will project a dim image with dull and inaccurate colors. Replacing the lamp at the manufacturer's specified hour limit is a simple process that will help maintain picture quality and reduce the risk of complete lamp failure at a less than convenient time.

Power the projector off. Unplug the power from the projector once the cooling fan has stopped running, and allow it to cool completely. The lamp is a sealed unit and cools slowly. Allow at least an hour for the lamp to cool enough to handle it safely.

Tips & Warnings
After replacing the lamp module, reset the lamp hours counter within the menu the next time the projector is powered on. This will maintain an accurate schedule for when the lamp will need to be replaced again.
Touching the glass lamp surfaces will leave traces of oil from the skin on the glass. Once the lamp gets hot, the oil causes weakening of the glass and results in premature lamp failure and the possibility of the lamp exploding within the projector.
