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 COMPO-
NENTS WITH SONY PARTS WHOSE PART NUMBERS APPEAR AS 
SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY 
SONY. 

LES COMPOSANTS IDENTIFIÉS PAR UNE MARQUE 0 SUR LES 
DIAGRAMMES SCHÉMATIQUES ET LA LISTE DES PIÈCES SONT 
CRITIQUES POUR LA SÉCURITÉ DE FONCTIONNEMENT. NE REM-
PLACER CES COMPOSANTS QUE PAR DES PIÈCES SONY DONT 
LES NUMÉROS SONT DONNÉS DANS CE MANUEL OU DANS LES 
SUPPLÉMENTS PUBLIÉS PAR SONY.

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 350°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.

Danger of explosion occurs if battery is incorrectly replaced.
Replace only with the same or equivalent type.
Dispose of used batteries according to the instructions.

This unit uses 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.)

Be careful to the following points to solder or unsolder.

•  Set the soldering iron tip temperature to 350°C approximately.
 

If cannot control temperature, solder/unsolder at high temperature 
for a short time.

 

Caution: The printed pattern (copper foil) may peel away if the 

heated tip is applied for too long, so be careful!

 

 

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.

•  Be sure to control soldering iron tips used for unleaded solder and 

those for leaded solder so they are managed separately. Mixing un-
leaded solder and leaded solder will cause detachment phenomenon.

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

Note1:  When replacing the Main Board Assy, erase the data in internal memory of main board before replacement.
Note2:  When replacing the Main Board Assy, execute formatting and initialize the internal memory after replacement.

Dedicated A/V cable is not supplied with this model.
For details of the dedicated A/V cable, refer to the “ACCESSORIES” page.

Formats the memory card or the internal memory.
When you use a memory card with this camera for the first time, it is recommended to format the card
using the camera for stable performance of the memory card before shooting. Note that formatting
permanently erases all data on the memory card, and is unrecoverable. Save precious data on a
computer, etc.

1.  MENU 

 

 (Settings) 

 

 (Memory Card Tool) or 

 (Internal Memory Tool) 

 [Format] 

 [OK] 

 

Note that formatting permanently erases all data including even protected images.

Copies all images in the internal memory to a memory card.

1.  Insert a memory card with sufficient free capacity into the camera.
2.  MENU 

 

 (Settings) 

 

 (Memory Card Tool) 

 [Copy] 

 [OK] 

 

Make sure there is sufficient battery power. Otherwise, the battery power may run out when you
attempt to copy image files, causing the copy to fail and possibly corrupt the data.
Images cannot be copied individually.
The original images in the internal memory are retained even after copying. To delete the contents
of the internal memory, remove the memory card after copying, then format the internal memory
([Format] in [Internal Memory Tool]).
A new folder is created on the memory card and all the data will be copied to it. You cannot choose
a specific folder and copy images to it.
