The circuit boards used in these models have been processed using
Lead Free Solder. The boards are identified by the LF logo located
close to the board designation e.g. F1, H1 etc [ see examples ]. The
servicing of these boards requires special precautions to be taken as
outlined below.
CAUTION
Lead Free Soldered Boards
example 1
example 2
It is strongly recommended to use Lead Free Solder material in order to guarantee optimal quality of new solder joints. Lead Free Solder is
available under the following part numbers :
Due to the higher melting point of Lead Free Solder the soldering iron tip temperature needs to be set to 370 degrees centigrade. This requires
soldering equipment capable of accurate temperature control coupled with a good heat recovery characteristics.
For more information on the use of Lead Free Solder, please refer to http://www.sony-training.com

BX-1L SELF DIAGNOSTIC SOFTWARE
BX-1L chassis TV’s contain a self diagnosis function. In the event of an error occurring, the STANDBY LED indicator will automatically begin
to flash. The number of times the STANDBY LED indicator flashes translates to a probable source of the problem. 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 error occurs, the STANDBY indicator will flash a set number of times to indicate the possible cause of the problem. If there is more
than one error, the indicator will identify the first of the problem areas.
The result for all of the following diagnosis items are displayed on screen. No error has occured if the screen displays a “0”.
* If a+B overcurrent is detected, then the vertical deflection is detected simultaneously. The symptom that is diagnosed first by the micro
controller is displayed on the screen.
** Refer to Screen (G2) Adjustment on page 19.

1. In order to reduce the influence of geomagnetism on the
set’s picture tube, face it in an easterly or westerly direction.
2. Switch on the set’s power and degauss with the degausser.
1. Input an all white signal from the pattern generator. Set the
Contrast and Brightness to normal.
2. Set the pattern generator raster signal to a Red raster.
3. Move the deflection yoke to the front and adjust with the
purity control so that the Red is at the centre and the Blue
and Green take up equally sized areas on each side of the
screen. [See Fig.3-1 - 3-3].
4. Move the deflection yoke backwards and adjust so that the
entire screen becomes Red. [See Fig.3-1]
5. Switch the raster signal to Blue, then to Green and verify
the condition.
6. When the position of the deflection yoke has been
determined, fasten the deflection yoke with the screws.
7. If the beam does not land correctly in all the corners, use a
magnet to correct it. [See Fig.3-4]

4. If the V.STAT magnet is moved in the direction of the (a)
and (b) arrows, the Red, Green and Blue points move as
indicated below.
1. [Moving horizontally], adjust the H.STAT control so that
the Red, Green and Blue points are on top of each other at
the centre of the screen.
2. [Moving vertically], adjust the V.STAT magnet so that the
Red, Green and Blue points are on top of each other at the
centre of the screen.
3. If the H.STAT variable resistor is unable to bring the Red,
Green and Blue points together at the centre of the screen,
adjust the horizontal convergence with the H.STAT variable
resistor and the V.STAT magnet in the manner indicated
below.
[In this case, the H.STAT variable resistor and the V.STAT
magnet influence each other].
The movement of the magnets interact with each other and so
the respective dot position should be monitored while carrying
out this adjustment.
Use the H.STAT VR to adjust the Red, Green and Blue dots so
that they coincide at the centre of the screen
(by moving the dots in the horizontal direction).
