Projection Lamp
Your TV uses a projection lamp as its light source. As
with any lamp, it has lifespan and needs to be replaced
when the Lamp indicator flashes or the screen
becomes darker.
Notes
After turning on your TV, it may take a while (1 minute or
less) before the picture appears.
When the projection lamp wears out, the screen goes dark.
Replace the lamp with a new Sony XL-2400 replacement
lamp (not supplied). How to replace the lamp, see page 5.
Warning
The light emitted from the lamp is quite bright when your TV
is in use. To avoid eye discomfort or injury, do not look into
the light housing when the power is on.
– 4 –
Replacing the lamp
The projection lamp, which illuminates the picture,
has a limited life.
If the screen becomes dark, the color looks unusual, or
the LAMP indicator on the front of the projection TV
flashes, it is time to replace the lamp with a new one
(not supplied).
WARNING
Electric appliances can cause fire or high temperature,
resulting in injury or death. Be sure to follow the instructions
below.
Use a Sony XL-2400 replacement lamp (not supplied) for
replacement. Use of any other lamp may damage the
projection TV.
Do not remove the lamp for any purpose other than
replacement. Doing so may cause injury or fire.
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 receptable once the lamp has been removed.
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.
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.

1
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.)
2
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.
3
Take the new lamp out of the box.
Do not touch the glass portion of the new
lamp.
Notes
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.
4
Remove the outside lamp cover.
Disposing of the lamp
This product contains mercury. For disposal or
recycling information, please contact your local
authorities.
Do not leave the used lamp near flammable
materials or within the reach of children.
Do not pour water onto the used lamp or put any
object inside the lamp. Doing so may cause the
lamp to burst.
5
Remove the lamp door.
Turn the knob counterclockwise to OPEN and pull
out the cover.

6
Pull out the lamp.
Hook a finger through the loop of the lamp handle
and pull the handle upwards. Then pull the lamp
straight out.
Notes
The lamp is very hot immediately after use. Never
touch 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.
7
Put the new lamp into its place.
Mount the new lamp securely. Failure to do so
may cause a fire or the screen to go dark.
9
Put the outside lamp cover back in its
place.
Notes
Consult your Sony dealer for a Sony XL-2400
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.
Note
If the lamp is not securely reattached, the self-diagnostic
function may be triggered and the POWER/STANDBY
indicator flashes three times.
8
Reattach the lamp door.
Turn the knob back to CLOSE and secure the
cover.

WARNING!!
AN ISOLATION TRANSFORMER SHOULD BE USED DURING
ANY SERVICE TO AVOID POSSIBLE SHOCK HAZARD, BECAUSE OF LIVE CHASSIS.
THE CHASSIS OF THIS RECElVER IS DIRECTLY CONNECTED
TO THE AC POWER LINE.
SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY SHADING AND MARK ! ON THE
SCHEMATIC DIAGRAMS, EXPLODED VIEWS AND IN THE
PAR TS LIST ARE CRITICAL TO SAFE OPERATION. REPLACE
THESE COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY. CIRCUIT ADJUSTMENTS THAT
ARE CRITICAL TO SAFE OPERATION ARE IDENTIFIED IN THIS
MANUAL. FOLLOW THESE PROCEDURES WHENEVER CRITICAL COMPONENTS ARE REPLACED OR IMPROPER OPERATION IS SUSPECTED.

1. Summary of Self-Diagnosis Function
-This device includes a self-diagnosis function.
-Incaseofabnormalities, the POWER/STANDBY indicator automatically blinks. It is
possible to predict the abnormality location by the number of blinks. The Instruction
Manual describes blinking of the POWER/STANDBY indicator.
-Ifthe symptom is not reproduced sometimes in case of a malfunction, there is recording of
whether a malfunction was generated or not. Operate the remote command to confirm the
matter on the screen and to predict the location of the abnormality.
2. Diagnosis Items and Prediction of Malfunction Location
-When a malfunction occurs the POWER/STANDBY indicator only blinks for one of the
following diagnosis items. In case of two or more malfunctions, the item which first
occurred blinks. If the malfunctions occurred simultaneously, the item with the lower
blink count blinks first.
-The screen display displays the results regarding all the diagnosis items listed below.
Thedisplay "0" means that no malfunctions occurred.
