What does it mean when the ON/STANDBY light flashes red on my Sony VPL-CX125?

If the ON/STANDBY indicator on your Sony Projector is flashing red twice repeatedly, it indicates that the internal temperature is unusually high. Check to ensure that nothing is blocking the ventilation holes. If you are using the projector at a high altitude, make sure that “High Altitude Mode” in the Setup menu is set to “On.”
