Check the thermal switch
The thermal switch is designed to open when the temperature in the lamp housing gets too high. When
the switch opens, the power supply shuts down, turning the projector off.
When a projector shuts down after operating for a few minutes, you need to check the thermal switch
operation. First, power up the projector with the top off (page 102). Let the projector run until it shuts
down. Measure the resistance at the cable connections. If the resistance is
zero
, replace the safety
switch assembly, which includes the thermal switch.
