Solution
Make sure that the ambient temperature is within specs: higher then 10°C (50°F). Let
the projector acclimate. Do not ignite the lamp, otherwise there is a risk for condensate.
Replace the temperature sensor at the air outlet channel.

Solution
Ensure that the air inlets are not blocked. Provide a sufficient free area at the front of the
projector so that fresh air can freely enter the air inlet channel.
Check if the wire unit (reference 11 image 5-28) of the temperature sensor is connected
with the power distribution board.
Replace the Fan Control Board. See "Replacing the Fan control board", page 278.
Replace the temperature sensor at the air outlet channel.
