Notes on chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be
damaged by heat.
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.
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.

SECTION 1
SERVICING NOTES
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK
OR BASE UNIT
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.
LASER DIODE AND FOCUS SEARCH OPERATION
CHECK
Carry out the “S curve check” in “CD section adjustment” and check
that the S curve waveform is output several times.
NOTE 1:
Regarding the notification symbol “R”
Because the number of the operating buttons of this product
are limited, some operations require use of the operating
buttons of the remote commander (RM-SP320 supplied with
the product). When a specific operation requires use of the
operating buttons of the remote commander (RM-SP320), “R”
is added to the specific operating procedure in this manual.
Example  MENU/NO “R”  The  MENU/NO  button of remote
commander.
NOTE 2:
Incorrect operations may be performed if the test mode is not
entered properly.
In this case, press the  ?/1  button to turn the power off, and
retry to enter the test mode.
DISC TRAY  LOCK
The disc tray lock function for the antitheft of an demonstration
disc in the store is equipped.
Procedure :
1. Press the  ?/1  button to turn the set on.
2. Press the  FUNCTION “R”  button or touch the  FUNCTION
button to set DVD function.
3. Insert a disc.
4. While the power is ON (excluding the mode of Power-ON
Animation mode), touch the  
x  
Sensor (on Touch Panel) and
press the  A  button simultaneously for several seconds.
5. The “Locked” display appears for a while and disc cannot be
removed any more even if the  A  button is pressed.
* To release this mode, repeat the above operation. The
“Unlocked” display appears and the Disc Tray Lock mode is
canceled.
Note:
When “LOCKED” is displayed, the slot lock is not released by
turning power on/off with the  ?/1  button.
NOTE OF REPLACING THE DMB07 BOARD
When replacing the DMB07 board, since the adjustment value is
not set up correctly,  “Drive Auto Adjustment” can’t be performed.
In this case, initialize Memory in the following procedures.
Procedure:
1. Set the test mode. (See page 25)
2. Press the [2] key of the remote commander, and set the “DRIVE
MANUAL OPERATION”. (See page 27)
3. Press the [6] key of the remote commander, and set the “2-6,
Memory Check”. (See page 29)
4. Press the [CLEAR] key of the remote commander, and initialize
Memory.
