Power and Start-up Problems
The projector communicates its status via an LED located on the keypad. When this status LED is green, you know
that the projector is working properly. When the status LED is solid red or flashing red, you know there are lamp,
power or startup problems. The frequency with which the status indicator blinks red indicates one of several error
codes. These error codes provide crucial information about projector malfunctions. In addition, this projector
includes an LCD message that provides you with additional information.
