1.

Check the area of your repair for unsoldered or poorly-soldered
connections.  Check the entire board surface for solder splashes
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.

Look for parts which, through functioning, show obvious 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.

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.)

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.

After correcting the original service problem, perform the following

safety checks before releasing the set to the customer.

CAUTION :
Danger of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type.

The data can be copied/erased by the operations on the Setup screen. (When erasing the data, execute formatting the internal memory.)

When replacing the SY-127 board, erase the data in internal memory of the board before replacement.

When replacing the SY-127 board or the IC381 on the SY-127 board, execute formatting and initialize the internal memory after 
replacement.

Copies all images in the internal memory to a “Memory Stick”.

1

Insert a “Memory Stick” having 32 MB or larger capacity.

2

Select [OK] with v on the control button, then press z.
The message “All data in internal memory will be copied Ready?” appears.

3

Select [OK] with v , then press z.
Copying starts. 

Use batteries with enough capacity or the AC Adaptor (not supplied). If you attempt to copy image files 
using batteries with little remaining capacity, the batteries may run out, causing copying to fail or possibly 
corrupting the data.
You cannot copy individual images.
The original images in the internal memory are retained even after copying. To delete the contents of the 
internal memory, remove the “Memory Stick” after copying, then execute the [Format] command in 

 

Internal Memory Tool.
You cannot select a folder copied on a “Memory Stick”.
The setting of 

 (Print order) marks is not copied even when you copy data.

OK

See the following procedure.

Cancel

Cancels the copying.

Formats the internal memory.

Note that formatting irrevocably erases all data in the internal memory, including even protected images.

1

Select [OK] with v on the control button, then press z.
The message “All data in internal memory will be erased Ready?” appears.

2

Select [OK] with v, then press z.
The format is complete.

OK

See the following procedure.

Cancel

Cancels the formatting.

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.

Initializes the setting to the default setting.

1

Select [OK] with v on the control button, then press z.
The message “Initialize all settings Ready?” appears.

2

Select [OK] with v, then press z.
The settings are reset to the default setting.

Make sure that the power is not disconnected during resetting.

OK

See the following procedure.

Cancel

Cancels the resetting.
