Replacing the Lamp
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.

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-5200 replacement lamp (not supplied) for replacement.
Use of any other lamp may damage the 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 receptacle 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.
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 are similar to those of a fluorescent lamp, so you
should dispose of it in the same way.
How to Replace the
Lamp
1
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.)
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 receptacle once the lamp has been removed.

3 Take th e 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.
4 Remove the outside lamp cover.
Release the two clamps as shown in the illustration below.
5 Remove the lamp door.
Turn the screw counterclockwise and slide the lever to the left. Remove
the door.
6 Pull out the lamp.
Hold the indented grooves on the top corners of the lamp, 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.
Hold this part of the lamp

•Do not touch the inside of the lamp compartment.
•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.
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.
•The lamp compartment is tilted, as shown in the following
illustration.
•If the lamp is not securely reattached, the self-diagnostic function
may be triggered and the POWER LED blinks three times.
8
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.

9
Put the outside lamp cover back in its place.
Replace the cover, inserting it from the left side. Press the two tabs on
the right side to secure the cover.
10
Turn on the TV and set the
settings. 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.

For customers in the United States:
This product contains mercury. Disposal of this product may be regulated if
sold in the United States. For disposal or recycling information, please
contact your local authorities or the Electronics Industries Alliance
(http://www.eiae.org).
•
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.

SAFETY CHECK-OUT
( US model only )
After correcting the original service problem, perfom the follow-
ing safety checks before releasing the set to the customer:
l. Check the area of your repair for unsoldered or poorly-sol-
dered connections. Check the entire board surface for solder
splashes and bridges.
2. Check the interboard wiring to ensure that no wires are
“pinched” or contact high-wattage resistors.
3. Check that all control knobs, shields, covers, ground straps,
and mounting hardware have been replaced. Be absolutely
certain that you have replaced all the insulators.
4. Look for unauthorized replacement parts, particularly transistors, that were installed during a previous repair. Point them
out to the customer and recommend their replacement.
5. Look for parts which, through functioning, show obvious
signs of deterioration. Point them out to the customer and
recom mend their replacement.
6. Check the line cords for cracks and abrasion. Recommend
the replacement of any such line cord to the customer.
7. Check the condition of the monopole antenna (if any). Make
sure the end is not broken off, and has the plastic cap on it.
Point out the danger of impalement on a broken antenna to
the customer, and recommend the antenna’s replacement.
8. Check the B+ and HV to see they are at the values specified.
Make sure your instruments are accurate;be suspicious of
your HV meter if sets always have low HV.
9. Check the antenna temminals, metal trim, “metallized” knobs,
screws, and all other exposed metal parts for AC leakage.
Check leakage as described below.
LEAKAGE TEST
The AC leakage from any exposed metal part to earth ground and
from all exposed metal parts to any exposed metal part having a
return to chassis, must not exceed 0.5mA (500 microampers) . Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or
RCA WT-540A. Follow the manufacturers’ instructions to
usc these instruments.
2. A battery-operated AC milliammeter. The Data Precision 245
digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a
VOM or battery-operated AC voltmeter. The “limit” indication is 0.75V, so analog meters must have an accurate lowvoltage scale. The Simpson 250 and Sanwa SH-63Trd are
examples of a passive VOM that is suitable. NearIy all battery operated digital multimeters that have a 2V AC range
are suitable. (See Fig. A)
HOW TO FIND A GOOD EARTH GROUND
A cold-water pipe is guaranteed earth ground;the cover-plate retaining screw on most AC outlet boxes is also at earth ground. If
the retaining screw is to be used as your earth-ground, verify that it
is at ground by measuring the resistance between it and a coldwater pipe with an ohmmeter. The reading should be zero ohms. If
a cold-water pipe is not accessible, connect a 60-l00 watts trouble
light (not a neon lamp) between the hot side of the receptacle and
the retaining screw. Try both slots, if necessary, to locate the hot
side of the line, the lamp should light at normal brilliance if the
screw is at ground potential. (See Fig. B)

SECTION 1
SELF DIAGNOSIS FUNCTION
1. Summary of Self-Diagnosis Function
-This device includes a self-diagnosis function.
-Incaseofabnormalities, the POWER indicatorautomatically blinks. It is possible to
predict the abnormality location by the number of blinks. The Instruction
describes blinking of thePOWER 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 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 lowe
