There are two kinds of OPTICAL PICK-UP BLOCK in this set.
When replacing the OPTICAL PICK-UP BLOCK, make sure which
OPTICAL PICK-UP BLOCK it is following the “How to Identify”
in the figure shown below.

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.

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.

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)

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.

The disc tray lock function for the antitheft of an demonstration
disc in the store is equipped.

1. Press the  

I

/1

  button to turn the power on.

2. Press the  

DVD

  button to select “DVD”.

3. While pressing the

x

button, press the  

Z

  OPEN/CLOSE

button

until “UNLOCKED” displayed on the fluorescent indicator
tube (around 5 seconds).

When “LOCKED” is displayed, the disc tray lock is not released by
turning power on/off with the

I/

1

button.

New part of EEPROM (IC103) on the DMB15 board cannot be
used. Therefore, if the mounted DMB15 board is replaced, exchange
new EEPROM with that used before the replacement.
