When should I replace the projection lamp?

• When one of the following conditions occurs the projection lamp should be replaced: 1. The projected image gets darker or starts to deteriorate. 2. The Error light on top of the projector is flashing red in 1-second intervals. 3. The LAMP REPLACE message appears on the screen when the projector lamp comes on (after about 1500 hours of use). To view the number of hours your lamp has been used, check the About menu.
