SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK 0OR DOTTED LINEWITH
MARK 0ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS
LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE
COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS
APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS
PUBLISHED BY SONY.
ATTENTION AU COMPOSANT AYANT RAPPORT
À LA SÉCURITÉ!
LES COMPOSANTS IDENTIFÉS PAR UNE MARQUE 0SUR LES
DIAGRAMMES SCHÉMATIQUES ET LA LISTE DES PIÈCES SONT
CRITIQUES POUR LA SÉCURITÉ DE FONCTIONNEMENT. NE
REMPLACER CES COMPOSANTS QUE PAR DES PIÈSES SONY
DONT LES NUMÉROS SONT DONNÉS DANS CE MANUEL OU
DANS LES SUPPÉMENTS PUBLIÉS PAR SONY.
1. Checktheareaofyour repair forunsoldered or poorly-soldered
connections. Checkthe entire boardsurface forsoldersplashes
and bridges.
2. Check the interboard wiring to ensure that no wires are
"pinched" or contact high-wattage resistors.
3. Look for unauthorized replacement parts, particularly
transistors, that were installed during a previous repair. Point
them out to the customer and recommend their replacement.
4. Lookforparts which, throughfunctioning, showobvious signs
of deterioration. Point them out to the customer and
recommend their replacement.
5. Check the B+ voltage to see it is at the values specified.
6. FLEXIBLE Circuit Board Repairing
•Keep the temperature of the soldering iron around 270°C
during repairing.
•Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
•Be careful not to apply force on the conductor when soldering
or unsoldering.
Unleaded solder
Boards requiring use of unleaded solder are printed with the lead-
free mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with
the lead free mark due to their particular size.)
: LEAD FREE MARK
Unleaded solder has the following characteristics.
•Unleaded solder melts at a temperature about 40°C higher than
ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to
about 350°C.
Caution: The printed pattern (copper foil) may peel away if the
heated tip is applied for too long, so be careful!
•Strong viscosity
Unleaded solder is more viscous (sticky, less prone to flow) than
ordinary solder so use caution not to let solder bridges occur such
as on IC pins, etc.
•Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.
SAFETY CHECK-OUT
After correcting the original service problem, perform the following
safety checks before releasing the set to the customer.
CAUTION
Dangerofexplosionifbatteryisincorrectlyreplaced.
Replace only with the same or equivalent type.

Checking of flash unit or replacement
of flash unit. (Note) Abnormality when flash is being
charged.
Note: After repair, be sure to perfom “1-2. PROCESS AFTER FIXING FLASH ERROR”.
1-2. PROCESS AFTER FIXING FLASH ERROR
When “FLASH error” (Self-diagnosis Code E : 91 : ** ) occurs, to prevent any abnormal situation caused by high voltage, setting of the
flash is changed automatically to disabling charge and flash setting.
After fixing, this setting needs to be deactivated. Flash error code can be initialized by the operations on the Setup screen.
Method for Initializing the Flash Error Code
Initializes the setting to the default setting.
1Select [OK] with von the control button, then press z.
The message “Initialize all settings Ready?” appears.
2Select [OK] with v, then press z.
The settings are reset to the default setting.

1-3. METHOD FOR COPYING OR ERASINGTHE DATA IN INTERNAL MEMORY
The data can be copied/erased by the operations on the Setup screen. (When erasing the data, execute formatting the internal memory.)
Note 1: When replacing the SY-144 board, erase the data in internal memory of the board before replacement.
Note 2: When replacing the SY-144 board or the IC202 on the SY-144 board, execute formatting and initialize the internal memory after
replacement.
Method for Copying the Data in Internal Memory
Method for Formatting the Internal Memory

NOTE FOR REPAIR
• Make sure that the flat cable and flexible board are not cracked of bent at the terminal.
Do not insert the cable insufficiently nor crookedly.
• When remove a connector, dont’ pull at wire of connector.It is possible that a wire is snapped.
•When installing a connector, dont’ press down at wire of connector.
It is possible that a wire is snapped.
•Do not apply excessive load to the gilded flexible board.
Cut and remove the part of gilt
which comes off at the point.
(Be careful or some
pieces of gilt may be left inside)
DISCHARGING OF THE ST-133 BOARD’S CHARGING CAPACITOR (C901)
The charging capacitor (C901) of the ST-133 board is charged
up to the maximum 300 V potential.
There is a danger of electric shock by this high voltage when the
capacitor is handled by hand. The electric shock is caused by
the charged voltage which is kept without discharging when the
main power of the unit is simply turned off. Therefore, the
remaining voltage must be discharged as described below.
Preparing the Short Jig
To preparing the short jig, a small clip is attached to each end of
a resistor of 1 kΩ/1 W (1-215-869-11).
Wrap insulating tape fully around the leads of the resistor to
prevent electrical shock.
1 kΩ/1 W
Wrap insulating tape.
Note: High-voltage cautions
Discharging the Capacitor
Short-circuit between the two points
with the short jig about 10 seconds.
R:1 kΩ/1 W

2-2-1. PEEL OFF OLD ORNAMENTAL RING A
The Ornamental Ring A has adhered to the Barrier Assy strongly and accordingly, use a soldering iron to weaken the adhesive force.
Heat four circled portions with the soldering iron.
Heating temperature is about 300ºC.
Beware of a burn since the entire Ornamental Ring becomes hot.
*As the adhesive force of Ornamental Ring A is considerably large, the forced peeling will damage the group-1 frame.
Insert the tip of tweezers, etc. into a notch of the group-1 frame and prize the ring.
*Take extreme care so as not to damage the coated surface of the group-1 frame.
In case of difficult peeling, heat the ring again with the soldering iron.
If this re-heating failed, it may be advisable that the ring be peeled while heating the portions 1→2in the under figure one by one
sequentially.
*Discard the removed Ornamental Ring A.

Apply an adhesive tape to two recesses on the top surface of the Barrier Assy.
Meeting a “notch” of the Ornamental RingA with a “projection” of the group-1 frame, push the Ornamental Ring A into the group-1 frame.
*The projection of the spring for preventing static electricity must be tilted.
Put the 60g weight on the Ornamental Ring A so that the Ornamental Ring A does not float up until the adhesive hardens.
Note: Be careful not to give a shock.
*After the weight was put, no gap must be present in full circumference between Ornamental Ring A and group-1 frame.
A gap, if present, causes the crackle sound NG.
*The weight must push in the Ornamental Ring A only.
If the weight is put on the mold part of the Barrier Assy, the Ornamental Ring A will float up.
Completion after 30 minutes.
