SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY SHADING AND MARK ! ON

REPLACE THESE COMPONENTS WITH SONY PARTS
WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS
MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY.
The units in this manual contain a self-diagnostic function. If an error occurs, the STANDBY/TIMER lamp will
automatically begin to flash.
The number of times the lamp flashes translates to a probable source of the problem. A definition of the STANDBY/
TIMER lamp flash indicators is listed in the instruction manual for the user’s knowledge and reference. If an error
symptom cannot be reproduced, the remote commander can be used to review the failure occurrence data stored in
memory to reveal past problems and how often these problems occur.
1.DIAGNOSTIC TEST INDICATORS
When an errors occurs, the STANDBY/TIMER lamp will flash a set number of times to indicate the possible cause of
the problem. If there is more than one error, the lamp will identify the first of the problem areas.
Result for all of the following diagnostic items are displayed on screen. No error has occured if the screen displays a
“0”.

For errors with symptoms such as “power sometimes shuts off” or “screen sometimes goes out” that cannot be confirmed, it is possible to bring up past occurances of failure for confirmation on the screen:
[To Bring Up Screen Test]
In standby mode, press buttons on the remote commander sequentially in rapid succession as shown below:

5. HANDLING OF SELF-DIAGNOSTIC SCREEN DISPLAY
Since the diagnostic results displayed on the screen are not automatically cleared, always check the self-diagnostic
screen during repairs. When you have completed the repairs, clear the result display to “0”.
Unless the result display is cleared to “0”, the self-diagnostic function will not be able to detect subsequent faults after
completion of the repairs.
[Clearing the result display]
To clear the result display to “0”, press buttons on the remote commander sequentially as shown below when the
diagnostic screen is being displayed.
Channel [8] / 0
[Quitting Self-diagnostic screen]
To quit the entire self-diagnostic screen, turn off the power switch on the remote commander or the main unit.

Using Your New TV
Pull the power cord out by the plug. Do not pull
the power cord itself. Even if your TV is turned
off, it is still connected to the AC power source
(mains) as long as the power cord is plugged in.
Unplug the TV before moving it or if you are not
going to use it for several days.
Install the TV on a stable TV stand and floor
which can support the TV set weight. Ensure that
the TV stand surface is flat and its area is larger
than the bottom area of the TV.

Preset the channels automatically
Tips
• If you want to stop automatic channel presetting, press SELECT twice.
• If your TV has preset an unwanted channel or cannot preset a particular
channel, then preset your TV manually (see page 10).
Notes
• If you connect a monaural VCR, connect the yellow plug to
(the yellow
jack) and the black plug to
-L (MONO) (the white jack).
• If you connect a VCR to the 8 (antenna) terminal, preset the signal
output from the VCR to the program number 0 on the TV.
• If both
(S video input) and t 1 (video input) at the rear of your TV
are input at the same time, the
(S video input) is automatically
selected. To view the video input to t 1 (video input), disconnect the
S video cable.
• Do not connect video equipment to the t 2 (video input) jacks at the
front and the rear of your TV at the same time; otherwise the picture will
not be displayed properly on the screen.
• When no signal is input from the connected video equipment, the TV
screen becomes blue.
