The projection lamp, which illuminates the picture, 
has a limited life.
If the screen becomes dark, the color looks unusual, 
“Projection lamp is nearing end of life. Please replace 
the lamp.” appears on the screen, or the LAMP 
indicator on the front of the LCD projection TV 
flashes, it is time to replace the lamp with a new one 
(not supplied).
This television uses a replaceable lamp as its light 
source. Over time, the screen will gradually grow 
darker as the lamp ages. Although rare, the lamp may 
make a small pop and will no longer light up. The 
lamp should be replaced after about 8,000 hours, 
which is the standard amount of time it takes for the 
lamp brightness to be reduced by half. Because the 
actual lamp life will vary depending on the operating 
conditions and environment, 8,000 hours is an 
estimate, not a guarantee.

Electric appliances can cause fire or high temperature, 
resulting in injury or death. Be sure to follow the instructions 
below.

Å Use a Sony XL-2400 replacement lamp (not supplied) for 

replacement. Use of any other lamp may damage the LCD 
projection TV.

Å Do not remove the lamp for any purpose other than 

replacement. Doing so may cause injury or fire.

Å Do not put flammable materials and metal objects inside 

the lamp receptacle of the TV after removing the lamp. 
Doing so may cause fire or electrical shock. Do not touch 
the lamp receptacle once the lamp has been removed.

Å When the lamp eventually burns out, you may hear a 

noticeable pop sound. This is normal and it is inherent to 
this type of lamp.

Å In rare instances, the bulb may pop inside the lamp unit, 

but the lamp unit is designed to contain all of the broken 
glass pieces inside the lamp unit.

Turn off the power on the main unit. Wait 
several minutes, then unplug the power 
cord.
(The cooling fan will continue to blow for 
about two minutes after turning the power 
off.)

Wait at least 30 minutes after unplugging 
the power cord to allow the lamp to cool 
down before replacing it. To avoid being 
burned, do not touch the lamp receptable 
once the lamp has been removed. 

Take the new lamp out of the box. 
Do not touch the glass portion of the new 
lamp.

Å Do not shake the lamp. Vibration can damage the 

lamp or shorten its life.

Å Avoid touching the front glass of a new lamp or the 

glass of the lamp receptacle. This may reduce picture 
quality or lamp life.

Remove the outside lamp cover.

Remove the lamp door.

Turn the knob counterclockwise to OPEN and pull 
out the cover.

This product contains mercury. For disposal or 
recycling information, please contact your local 
authorities.

Å Do not leave the used lamp near flammable 

materials or within the reach of children.

Å Do not pour water onto the used lamp or put any 

object inside the lamp. Doing so may cause the 
lamp to burst.
