When the TEMP indicator and the
LAMP indicator are illuminated
There are two indicators on the control panel of the projector which give
information about the operating condition of the projector. These indicators
illuminate or flash to warn you about problems that have occurred inside the
projector, so if you notice that one of the indicators is on, turn off the power
and check the table below for the cause of the problem.
