- Lamp Replacement: The projector lamp has a finite lifespan. When the lamp life indicator appears, or the image brightness significantly decreases, replace the lamp according to the instructions provided in the full service manual or by a qualified technician. Always allow the projector to cool down completely before attempting lamp replacement.
