Troubleshooting
Cause and Remedy
c Check the setting of "High Altitude Mode" in the Setup menu
(see page 38).
c Check the ventilation holes are not blocked.
c Make sure the room temperature is not too high.
To maintain the product reliability of the projector's components,
the rotation speed of the fan increases and the fan becomes
slightly noisier, when the room temperature exceeds normal. The
approximate normal temperature is 25°C.
Cause and Remedy
• The lamp cover or the air filter cover is detached.
c Attach the cover securely (see page 47).
• The lamp has reached the end of its life.
c Replace the lamp (see page 46).
• The lamp has reached a high temperature.
c Wait for 60 seconds to cool the lamp and then turn on the power
again.
The shutter fails to operate properly.
c Consult with qualified Sony personnel.
• The internal temperature is unusually high.
c Check to see that nothing is blocking the ventilation holes.
• The projector is being used at a high altitude.
c Ensure that "High Altitude Mode" in the Setup menu is set to
"On."
The fan is broken.
c Consult with qualified Sony personnel.
Unplug the AC power cord from the wall outlet after the ON/
STANDBY indicator goes out, plug the power cord to the wall
outlet, and then turn the projector on again. If the ON/STANDBY
flashes in red and the problem persists, the electrical system has
failed.
c Consult with qualified Sony personnel.
• The lamp must be replaced.
c Replace the specified lamp (Lamp 1 or 2) (see page 46).
* The lamp that needs to be replaced lights.
• The lamp temperature has been high.
c Wait for more than 60 seconds so that the lamp cools, and then
turn on the power again.
* The lamp that has fails to light is shown.
The projector is in muting mode.
c To cancel it, press the MUTING (PIC) key on the Remote
commander.
