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.

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.

When replacing the lens, write down the Tele Limit Data given on the data sheet of the replacement lens for service.
Execute the J20 Write Zoom Calib Value.
For details of adjusting method, please refer to the Service manual ADJ of DSC-J20 (9-834-665-5[]).
