							80Replacing the Lamp
Replacing the Lamp
Replace the lamp with a new one if a message displayed on the projected image (page 90).
Use an LMP-E220 projector lamp (not supplied) for replacement.
 The lamp remains hot after the projector is 
turned off. If you touch the lamp, you may 
burn your finger. When you replace the 
lamp, wait for at least an hour after 
turning off the projector for the lamp to 
cool sufficiently.
 Do not allow any metallic or inflammable 
objects into the lamp replacement slot after 
removing the lamp, otherwise it may cause 
electrical shock or fire. Do not put your 
hands into the slot.
If the lamp breaks, contact qualified 
Sony personnel. Do not replace the lamp 
yourself.
 When removing the lamp, be sure to pull it 
out straight, by holding the designated 
location. If you touch a part of the lamp other 
than the designated location, you may be 
burned or injured. If you pull out the lamp 
while the projector is tilted, the pieces may 
scatter if the lamp breaks any may cause 
injury.
1Turn off the projector, and disconnect 
the AC power cord from a wall outlet.
2When the lamp has cooled 
sufficiently, open the lamp cover by 
loosening 1 screw. 
3Loosen the three screws on the lamp 
(1) then pull out the lamp by its grab
