Check the Thermal Switch
The thermal switch is designed to open when the temperature inside the projector gets too high. When
the switch opens, the power supply shuts down, turning the projector off.
When the projector shuts down after operating for a few minutes or when the lamp fails to strike after
repeated attempts at startup, check the thermal switch. First, power up the projector with the top off (page
60). Let the projector run until it shuts down. Measure resistance across the terminals at the thermal
switch. If the resistance is
infinite
(
Ω)
, replace the lamp housing, which includes the thermal switch.
For removal and replacement, see page 26.
NOTE
You can also check the continuity of the safety switch, which fastens to the lamp housing next to
the thermal switch. When the switch is closed, it should measure zero ohms. If the resistance is
infinite
(
Ω)
, replace the lamp housing, which includes the thermal switch.
