Thermal protectors (SW901, SW902)
There are the thermal protectors (SW901, SW90) inside of
the projector to detect the internal temperature rising abnor-
mally. When the internal temperature reaches near 100˚C,
the thermal protector cuts off the current supplied to the
power supply circuit.
To reset the thermal protection function, disconnect the AC
cord and leave the projector at the normal surrounding tem-
perature for about 45 minutes. The thermal protectors will
automatically reset when the internal temperature becomes
normal (around 60˚C).
