The projection lamp, like all lamps, will eventually 
lose brightness and functionality, which affects the 
overall performance of your TV. How long the 
lamp maintains its brightness will vary depending 
upon your usage and environmental conditions. To 
maintain the quality of your viewing experience, 
Sony recommends that you replace the lamp (1) 
after approximately 8,000 hours of use; (2) when 
the screen becomes dark or the color looks 
unusual; (3) when the LAMP LED on the front of 
the TV blinks; or (4) when the lamp replacement 
message appears on the TV screen.

s Use a Sony XL-5200 replacement lamp (not 

supplied) for replacement. Use of any other 
lamp may damage the TV.

s Do not remove the lamp for any purpose other 

than replacement. Doing so may cause injury 
or fire.

s 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.

s 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.

s 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.

s This TV’s lamp contains mercury and should 

be disposed of properly. Consult your local 
authorities regarding safe disposal. The 
material contained in this lamp is similar to 
those of a fluorescent lamp, so you should 
dispose of it in the same way.

Turn off the power on the main unit. Wait 
several minutes, then unplug the power cord.
(The cooling fan will continue to operate 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 receptacle once the lamp 
has been removed.

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

~

• Do not shake the lamp. Vibration can damage the lamp 

or shorten its life.

• 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.
Press the clamp and the button at the same 
time to release the cover.

Remove the lamp door.
Turn the screw counterclockwise and slide the 
lever to the left. Remove the door.

Pull the lamp out of the TV.
Hold the indented grooves as shown in the 
illustration, and pull the lamp straight out. If 
the lamp is hard to remove, pull the right side 
of the lamp for additional traction.

~

• The lamp is very hot immediately after use. Do not 

touch the inside of the lamp compartment, the glass 
portion of the lamp, or the surrounding parts. 

• After the used lamp has cooled, place it into the empty 

box of the replacement lamp. Never put the used lamp 
into a plastic bag.

Slide the new lamp into its place.
Insert the new lamp by pressing the two parts 
firmly into place as shown in the illustration. 
Make sure the lamp is securely mounted into 
the compartment. Failure to do so may cause a 
fire or the screen to go dark.

Reattach the lamp door.
Replace the door by inserting the two tabs in 
the slot from the left side. Slide the lever to 
the right and then turn the screw clockwise to 
secure the door.

~

• If the lamp is not securely reattached, the self-

diagnostic function may be triggered and the POWER 
LED blinks six times (see page 24).

Put the outside lamp cover back in its place.
Replace the cover, inserting it from the right 
side. Press the clamp on the left side to secure 
the cover.

Plug in the power cord. Turn on the TV and 
set the 

 option in the 

 settings (see page 43). This setting is 

necessary to inform you when the next lamp 
replacement is needed.

~

• Until you set the Lamp Replacement option, a 

message announcing that the lamp is at the end of its 
life will appear every time you turn on the TV.

• Consult your Sony dealer for a Sony XL-5200 

replacement lamp.

• Take great care when replacing the lamp or plugging 

in/unplugging the connecting cords. Rough handling 
may cause the TV to fall, damaging the TV, the TV 
stand and the floor.

Lamp in this product contains mercury. Disposal 
of these materials may be regulated due to 
environmental considerations. For disposal or

s Do not leave the used lamp near flammable 

materials or within the reach of children.

s Do not pour water onto the used lamp or put 

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

Perform the adjustments in the following sequence. 

1.  Remove the Vertical Position Support plate by removing the silver screw, then pull the plate 

straight off.

2.  Perform Vertical geometry adjustment to achieve the best possible straight up-and-down 

vertical alignment of both the right and left sides of the picture. Grasp the adjuster knob and 
slide right or left into positions 1 through 5. 
NOTE: Use the screen assembly bezel inner edges as your reference and align the cross-
hatch outer most right and left lines to this edge.

3.  Re-install and securely screw the Vertical Position Support plate back into position. Make 

sure to rotate the plate to the proper tab thickness for effective vertical position support. 
NOTE: There are four different tab thicknesses to choose from on the inner side of the plate. 
With the plate off, note the position of the Optical Block post in the chassis hole and the area 
below the tab to choose the proper thickness.

4.  After reinstalling the Vertical Position Support plate, confi rm that the Vertical Geometry 

adjustment is OK.

5.  If the Vertical Geometry has shifted repeat steps 1 through 4 until you have achieved the 

best possible Vertical Geometry on the picture. 

 

If the Vertical Geometry is OK after re-installing the Vertical Position Support plate, then 
proceed to Step 6.

6.  Perform the Horizontal Geometry adjustment to achieve the best possible straight horizontal 

edge along the top of the picture by removing the silver screw for the adjustment. 
NOTE: The screw goes through the hole in the plastic chassis and a hole in the internal 
adjustment wheel. 
Turn the adjustment knob with a quarter until a hole on the internal wheel aligns with the 
hole in the chassis. Reinstall the screw securely and check the horizontal alignment on the 
screen. 
Repeat this process if needed until you achieve the best possible horizontal geometry. Use 
the screen assembly bezel upper inner edge as your reference and align the cross-hatch 
upper most line to this edge.
