Circuit Protections
There are the thermostat switches (SW903, SW904, SW905 and SW906)
inside of the projector to detect the internal temperature rising abnormally.
When the internal temperature reaches near 90˚C, the thermostat opens to
stop the operation of the power supply circuit.
The thermostat will automatically return to normal condition when the inter-
nal temperature becomes normal.
