SAFETY CHECK-OUT
After correcting the original service problem, perform the following
safety checks before releasing the set to the customer.
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.
SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH
MARK 0 ON 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 .
Unleaded solder
Boards requiring use of unleaded solder are printed with the leadfree 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.

• NOTE FOR REPAIR
1. SERVICE NOTE
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.
Cut and remove the part of gilt
which comes off at the point.
(Take care that there are
some pieces of gilt left inside)
When remove a connector, don't pull at wire of connector.
Be in danger of the snapping of a wire.
When installing a connector, don't press down at wire of connector.
Be in danger of the snapping of a wire.
[Discharging of the FLASH unit’s charging capacitor]
The charging capacitor of the FLASH unit 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 DSC-H1 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.
Discharging the Capacitor
1 Remove the main section.
2 Discharge the capacitor on the ST -123 board for about 10 seconds
by using the short jig.

• METHOD FOR COPYING OR ERASING THE DATA IN INTERNAL MEMORY
p
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-127 board, erase the data in internal memory of the board before replacement.
Note: 2 When replacing the SY-127 board or the IC381 on the SY-127 board, execute formatting and initialize the internal memory after
replacement.
Method for Copying the Data in Internal Memory
Copy
Copies all images in the internal memory to a “Memory Stick”.
OK
Cancel
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 pr es s z.
Copying starts.
Copying
102_COPY
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.
See the following procedure.
Cancels the copying.
Method for Formatting the Internal Memory
Format
Formats the internal memory.
Note that formatting irrevocably erases all data in the internal memory, including even protected images.
OK
Cancel
1 Select [OK] with v on the control button, then press z.
The message “All d ata in internal memory will be erased Ready?” appears.
2 Select [OK] with v, then press z.
The format is com
lete.
See the following procedure.
Cancels the formatting.
• 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
Initialize
Initializes the setting to the default setting.
OK
Cancel
See the following procedure.
Cancels the resetting.
DSC-H1
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.
