SECTION  1
SERVICING  NOTES
The laser diode in the optical pick-up block may suffer electrostatic
break-down because of the potential difference generated by the
charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic break-down and also
use the procedure in the printed matter which is included in the
repair parts.
The flexible board is easily damaged and should be handled with
care.
NOTES  ON  LASER  DIODE  EMISSION  CHECK
The laser beam on this model is concentrated so as to be focused on
the disc reflective surface by the objective lens in the optical pick-
up block. Therefore, when checking the laser diode emission,
observe from more than 30 cm away from the objective lens.
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 viscou-s (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.

Replacement of K4D263238G-VC36T (IC5500) on the BE board
and 
µ
PD61120AF1-100-JN1-A (IC3100) on the N board used in
this set requires a special tool.
NOTE  OF  REPLACING  THE  EEPROM (IC103)  ON
THE  DMB13  BOARD
EEPROM (IC103) on the DMB13 board cannot exchange with
single. When EEPROM (IC103) on the DMB13 board is damaged,
exchange the entire mounted board.
NOTE  OF  HANDLING  THE  P  BOARD (Part No. A-
1115-078-G)
When the P board is replaced by a repair for a fee, throw away the
P board after obtaining consent of not returning of the P board to
the customer. When throwing away the P board, be sure to throw
away after destroying P board physically with the hammer etc.
ABOUT  THE  CASE  WHERE  “DEMO”  OR  “LOCKED”
IS DISPLAYED  ON  THE  FLUORESCENT  INDICATOR
TUBE
The case where “DEMO” or “LOCKED” is displayed on the
fluorescent indicator tube when operating this set, refer to LIFT
DEMO MODE (page 39) (for case where “DEMO” is displayed)
and TRAY LOCK MODE (page 35) (for case where “LOCKED” is
displayed) on the Section 4. TEST MODE.

DVD block
CAUTION
When performing the repair with the DVD block 
in up state, place a pedestal to prevent the part 
to be repaired from falling, as shown below.
Note: If the DVD block of the set to be repaired can be moved up 
and down, set the DVD block to the position described 
below according to the part to be replaced, so that you can 
disassemble the set easily.
(The set can be disassembled even if the DVD block cannot 
be set to the specified position.)
1. If a part of DVD block is replaced:
Set the DVD block to the down position.
2. If a part other than DVD block is replaced:
Set the DVD block to the up position.
