The temperature light red. What should I do?

• The projector is overheating, which automatically turns the projector off. Let the projector cool for a few minutes, then turn it back on. Make sure nothing is blocking the ventilation vents. Check to see if the air filter is clogged. If it is, clean the filter by following the steps in your User's Guide. Let the projector cool for a while after cleaning the air filter. If the projector continues to overheat after you clean the air filter, the problem may be caused by damage to the cooling fan or internal circuits.
