possible solutions above and then wait until the projector has cooled down completely before plug-
ging in the power cord and turning the power back on. (At least 10 minutes.)

the projector, and the power supply recovers immediately after that, the lamp indicator will illumi-

trolled automatically. The sound of the cooling fan may change during operation because the fan
speed may change and this is not a malfunction.
