Indicators
The indicators show the current status of your TV. If there is a change in the
condition or a problem with the TV, the indicators will flash or light up in
the manner described below to let you know that it requires your attention.
Indicator Flashing because...
POWER/ green : The lamp for the light source is preparing to turn
STANDBY flashing on. When it is ready, it turns on.
red : The lamp door or the lamp is not securely attached.
The red indicator will continue to flash in intervals of three
blinks at a time until the lamp door or the lamp is placed
correctly. When the lamp door or the lamp is securely
attached, the TV will turn on with green indicator.
LAMP indicator The projection lamp has burned out. Replace it with new
flashes one (see page 86).
TIMER indicator is When one of the timers is set, the indicator will remain lit
lit (will not flash) even when the TV is turned off.
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. Note the following:
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).
The light emitted from the lamp is quite bright when your TV i s in
use. To avoid eye discomfort or injury, do not look into the light
housing when the power is on.

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 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 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.
The lamps contain mercury. For proper disposal of the used lamps,
follow and observe the local ordinances. See page 89.
How to Replace the 1 Turn off the power on the main unit. Wait several minutes, then unplug
Lamp 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 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.
Do not shake the lamp. Vi bration can damage the lamp or
shorten its life.
Avoid touching the front glass of a new lamp or the glass of
the lamp receptacle. Th is may reduce picture quality or lamp
life.

SELF DIAGNOSIS FUNCTION
1. Summary of Self-Diagnosis Function
- This device includes a self-diagnosis function.
- In case of abnormalities, 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.
- If the 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.
The display "0" means that no malfunctions occurred.

- Release of POWER/STANDBY indicator blinking
The POWER/STANDBY indicator blinking display is released by removing the plug from
the power or leaving for 2 minutes.
4. Self-diagnosis screen displays
- In cases 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.
- Quickly press the remote command button in the following order from the standby state.

- The results display is not automatically cleared. In case of repairs and after repairs, check
the self-diagnosis screen and be sure to return the results display to "0".
- If the results display is not returned to "0" it will not be possible to judge a new malfunction
after completing repairs.

2 : Temp When the temperature sensor on the S2 board detects high temperature, or IIC
line connector (CN8410:AGU board, CN7180:S2 board) is not seated securely,
the TV-micro tums off the lamp.
When the temperature sensor on the HB board detects high temperature, or IIC
line connector (CN8004:AGU board, CN7020:HB board) is not seated securely,
the TV-micro tums off the lamp.
3 : Lamp cover The rib at the back of the lamp cover closes the SW on the T1 board. The lamp
closes the SW on the T2 board.
It is monitored by the BE micro (pin133 of IC4100) and tums off the lamp when
it is opened.
4 : Fan Fan rotation is detected by ``FAN-PROT" and the TV-micro (pin 38 of IC8002)
tums off the lamp when it is ``high".
5 : Lamp Driver When the ``LAMP-PROT" (pin132 of IC4100) is high, the lamp is not tumed
on. If the ``LAMP-HV-DET" (pin134 of IC4100) is low at the same time, it
is classified as no high voltage of the lamp driver.
6 : Low B error When no ``B_12V" is detected, pin 128 of TV-micro is low and it tums off the
main power.
7 : Audio When DC voltage is detected at the speaker output, pin 149 of TV-micro is low
and it tums off the main power.
8 : D-OVP When overvoltage of ``B_12V" is detected, pin 127 of TV-micro is low and it
tums off the main power.
10 : ATSC-OVP When overvoltage of ``Q_10.5 V" is detected, pin 126 of TV-micro is low
and it tums off the main power.
LAMP : Lamp When the ``LAMP-PROT" (pin132 of IC4100) is high, the lamp is not tumed
on. If the ``LAMP-HV-DET" (pin134 of IC4100) is high at the same time, it
is classified as no lamp or a dead lamp.
