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 colour looks unusual; (2) 
when 
 on the front of the TV flashes; or (3) after 
approximately 8,000 hours of use.
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 (for KDS-55A2000) or XL-5300 
(for KDS-70R2000) 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.
1
Switch off the TV. Wait several minutes, 
then unplug the mains lead.
(The cooling fan will continue to operate for 
about two minutes after switching the TV 
off.)
2
Wait at least 30 minutes after unplugging 
the mains lead 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 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.

Remove the lamp door.
Turn the screw counterclockwise. Then 
slide the lever to the left (KDS-55A2000) or

Remove the door.

Pull out the lamp.
Hold the indented grooves on the top 
corners of the lamp. Then pull the right side

Notes
• Do not touch the inside of the lamp compartment.
• The lamp is very hot after use. Never touch the glass 
portion of the lamp or the non-designated 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.
Make sure the lamp is securely mounted 
into the compartment. Failure to do so may 
cause a fire or the screen to go dark.

Notes
• The lamp compartment is tilted.
• If the lamp is not securely reattached, the self-

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

Turn on the TV and set the Lamp 
Replacement option in the Set-up menu 
(page 32).
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-5200 (for 
KDS-55A2000) or XL-5300 (for KDS-70R2000) 
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 example, the indicator flashes three times, then there is a two second break, followed by another three flashes, etc.
2
Press 
1 on the TV (front) to switch it off, disconnect the mains lead, and inform your dealer or Sony 
service centre of how the indicator flashes (number of flashes).

Picture flashes initially when 
changing to HDMI mode or 
when switching on the TV in 
HDMI mode
• This is probably caused by the authentication process between HDMI 
equipment and the TV. It does not indicate a malfunction.
A white oval image appears on 
the screen
• This is due to strong light reflecting off both the TV screen and reflections 
coming from behind the screens.
• Position your TV away from strong ambient light or sunlight, or lower any 
ambient lights.
Sound
Problem
Cause/Remedy
No sound, but good picture
• Press 
2 +/– or % (Mute).
• Check that “Speaker” is set to “On” in the “Set-up” menu (page 32).
Noisy sound
• See “Picture noise” causes/remedies on page 52.
Channels
Problem
Cause/Remedy
The desired channel cannot be 
selected
• Switch between digital and analogue mode and select the desired digital/
analogue channel.
Some channels are blank
• Scrambled/Subscription only channel. Subscribe to the Pay Per View 
service.
• Channel is used only for data (no picture or sound).
• Contact the broadcaster for transmission details.
Digital channels are not 
displayed
• Contact a local installer to find out if digital transmissions are provided in 
your area.
• Upgrade to a higher gain aerial.
General
Problem
Cause/Remedy
The TV turns off automatically 
(the TV enters standby mode)
• Check if the “Sleep Timer” is activated, or confirm the “Duration” setting of 
“On Timer” (page 31).
• If the inside of the TV grows warm while Cooling Mode is set to “High”, 
the TV automatically switches to standby mode.
(When Cooling Mode is set to “Normal” under the same conditions, the 
mode switches to “High”, the cooling fan starts, and a loud whirring noise 
may be heard.)
The TV turns on automatically
• Check if the “On Timer” is activated (page 31).
Some input sources cannot be 
selected
• Select “AV Preset” in the “AV Set-up” menu and cancel “Skip” of the input 
source (page 34).

Uneven color uniformity 
appears on the screen when 
the TV is powered on
• After turning on the TV,  you may notice a slight color (tint) variation in 
certain areas of the picture. This will last only a few minutes each time you 
turn on the TV. This is a normal temperature characteristic of the 
components and not a malfunction.
The remote does not function
• Check that the remote is set correctly for the equipment you are using.
• Check whether the equipment you want to use corresponds to the function 
button being pressed (page 15).
• If the remote does not operate the equipment even when the remote has been 
set correctly to the equipment, enter the necessary code as explained in 
“Programming the remote” (page 45).
• Replace the batteries.
 indicator flashes in red
• Replace the lamp (page 47).
The TV does not switch on
• The TV cools down its projection lamp after being switched off. It takes up 
to two minutes for the picture to come back after the TV is switched on 
again. Wait for a while until the picture returns.
Cannot play shooting games
• Some shooting games that involve pointing a light beam at the TV screen 
with an electronic gun or rifle cannot be used with your TV. For details, see 
the instruction manual supplied with the video game software.
Standby indicator flashes in 
intervals of some blinks at a 
time
• Three blinks: The lamp cover or the lamp itself is not securely attached.
• Two blinks: If there is a considerable rise in temperature inside the TV such 
as when any ventilation openings are blocked.
• Other: Consult your dealer or service.
A slight creaking noise occurs 
from the bottom part of the TV
• Advanced Iris applies a mechanical iris system. When Advanced Iris is 
turned On/Off, a natural creaking noise occurs due to the basic structure of 
the optical unit. The creaking sound is an inherent nature of this system and 
is not a defect.
High Temperature Warning 
message appears
• This message will appear when there is a rise in temperature inside the TV. 
Make sure to remove dust from the ventilation slots on the rear and both 
sides of the TV. In addition, make sure that there are no obstacles in front of 
the ventilation slots. If no blockage is found, you may need to set Cooling 
Mode to “High”, otherwise the TV will turn off. With Cooling Mode set to 
“High”, if the message reappears and the TV turns off again, the TV may 
need servicing. Call your local Sony Service Center.
