Cause and Remedy

Check to see that nothing is blocking the ventilation holes.

Ensure that "High Altitude Mode" in the Setup menu is set to
"On."
The fan is broken.

Consult with qualified Sony personnel.
Unplug the AC power cord from the wall outlet after the ?/1 key
goes out, plug the power cord to the wall outlet, and then turn the
projector on again. If the ?/1 key flashes in red and the problem
persists, the electrical system has failed. Or the interior of the unit
reached a high temperature, and the temperature fuse has burned out.

The installation angle is outside the proper range.
