Replacing a lamp
If the screen becomes dark, the color looks unusual, or
the LAMP indicator on the front of the monitor flashes,
it is time to replace the lamp with a new one.
Before replacement
• Be sure to use the Sony XL-100U lamp unit (not supplied) for
replacement. Use of other lamps causes damage to the
monitor.
• Do not remove the lamp for any purpose other than
replacement.
• Before replacement, be sure to turn off the monitor and unplug
the power cord.
• When replacing the lamp, let it cool down completely, as the
surface of the lamp remains hot for at least 30 minutes after the
power has been switched off.
• Do not leave the removed lamp near the inflammable
materials.
• Do not pour water onto the removed lamp, nor put any object
inside the lamp.
• Do not put inflammable materials and metal objects inside the
lamp receptacle on the monitor, after removing the lamp. Do
not touch the receptacle.
• Fit the new lamp securely, otherwise the screen may become
dark, or it may cause fire.
1
Turn off the power switch on the monitor
and unplug the power cord.
Wait at least 30 minutes to allow the lamp to cool
down before replacing it .
2
Remove the front panel.
3
Untighten the screw with a coin or similar
object to remove the lamp cover.
4
Loosen the two screws that secure the
lamp, then pull out the lamp.
The lamp is very hot immediately after use. Never
touch the front glass of the lamp or the
surrounding parts.
Loosen the two screws with the hexagon
head wrench (supplied with the lamp).
Pull out straight towards you by holding the
handle.
Replace the removed lamp into the empty box of
the replacement lamp.
5
Mount the new lamp and tighten the two
screws securely.
6
Mount the lamp cover and tighten the
screw.
7
Mount the front panel.
Be careful not to damage the speakers of the
monitor.
Notes
• Do not touch the front glass of a new lamp or the glass of the
lamp receptacle. This may reduce picture quality or lamp life.
• Be sure to attach the lamp securely. Otherwise, the monitor
will not turn on.
• A laud sound may be heard when the lamp burns. This is not
dangerous.
• Consult your Sony dealer for the XL-100U lamp unit.
Pull the panel towards you, holding its right
end. Be careful not to damage your nails.
Hold the monitor tightly.
