Switches the TV on or off.
Note
Make sure that the TV is completely switched off before
unplugging the AC power cord. Unplugging the AC
power cord while the TV is turned on may cause the
indicator to remain lit or may cause the TV to
malfunction.
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 switching 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-5100 replacement
lamp (for KS-60R200A/50R200A, not supplied) or XL5300 replacemant lamp (for KS-70R200A, supplied).
How to replace the lamp, see page 39.
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.

RM-GA006 RM-GA006 RM-GA006
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) when the
screen becomes dark or the color looks unusual; (2)
when on the front of the TV flashes; (3) after
approximately 8,000 hours of use (for KS-60R200A/
50R200A) or 4,000 hours of use (for KS-70R200A);
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-5100 replacement lamp (for KS60R200A/50R200A, not supplied) or XL-5300
replacemant lamp (for KS-70R200A, 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.
1 Switch off the TV. Wait several minutes,
then unplug the power cord.
(The cooling fan will continue to operate for
about two minutes after switching the TV
off.)
3 Take the new lamp out of its package.
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.
For KS-60R200A/50R200A, turn the screw
with a screwdriver counterclockwise and
remove the cover.
For KS-70R200A, release the clamp and
remove the cover.

turn the knob to the left until the marks on
the lid and the case line up. Remove the
door.
KS-70R200A
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.

inform you when the next lamp
replacement is needed.
Notes
•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 switch on the TV.
•Consult your Sony dealer for a Sony XL-5100
replacement lamp (for KS-60R200A/50R200A) or
XL-5300 replacement lamp (for KS-70R200A).
•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.

SELF DIAGNOSIS FUNCTION
1. Summary of Self-Diagnosis Function
-This device includes a self-diagnosis function.
-Incaseofabnormalities, the 1-On/ standby
predict the abnormality location by the number of blinks. The Instruction
describes blinking of indicator.
the 1-On/ standby
-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 1-On/ standby indicator only blinks for one of the
following diagnosis items. In case oftwo or more malfunctions, the item which first
occurred blinks. If the malfunctions occurred simultaneously, the item with the lowe
blink count blinks first.
-The screen display displays the results regarding all the diagnosis items listed below.
Thedisplay "0" means that no malfunctions occurred.

When the inside temperature sensed with IC3150,
IC3200 and IC2000 mounted on S1 board, S2 board
and C board respectively exceed the threshold,
DEM (Display Engine u-com) detects it and makes
turn off the lamp.
When the lamp cover is opened or harness from T
board is off, DEM detects it and makes turn off the
lamp.
Note: 50,60 inch…Not Insert Lamp House
When any FAN is stopping or harness is not
connected correctly, DEM detects it and makes
turn off the lamp.
Note: Handle With Care
When the ballast is not working correctly, DEM
detects it and makes turn off the lamp.
When 11V, 7 V, 16.5V, Audio Vcc line is low,
bimetal or PS8205(AG board) is open, TVM (TV ucom) detects it and makes turn off the lamp.
When DC is appeared at speaker +/- line or
happened audio amp failures, TVM detects it and
makes turn off the lamp.

When the temperature sensor and bus decoder ICs
do not return ACK on IIC bus to DEM, DEM detects
it and makes turn off the lamp.
When the lamp is broken, DEM detects it.

• If panel fan connector does not connect
– It cause fan error several minutes later from power on.
4. Self-diagnosis screen displays
-Incases of malfunctions where it is not possible to determine the symptom such as when the power goes off
occasionally or when the screen disappears occasionally, there is a screen display on whether the malfunction
occurred or not in the past (and whether the detection circuit operated or not) in order to allow confirmation.
