NOTES  ON  CHIP  COMPONENT  REPLACEMENT
• 

Never reuse a disconnected chip component.

• 

Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.

FLEXIBLE  CIRCUIT  BOARD  REPAIRING
• 

Keep the temperature of 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.

CAUTION
Use of controls or adjustments or performance of procedures 
other than those specifi ed herein may result in hazardous radia-
tion exposure.

The laser diode in the optical pick-up block may suffer electro-
static 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 fl exible 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 refl ective surface by the objective lens in the optical 
pickup block. Therefore, when checking the laser diode emission, 
observe from more than 30 cm away from the objective lens.

NOTES  ON  DUALDISCS
A DualDisc is a two sided disc product which mates DVD record-
ed material on one side with digital audio material on the other 
side. However, since the audio material side does not conform to 
the Compact Disc (CD) standard, playback on this product is not 
guaranteed.

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)

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 viscous (sticky, less prone to fl ow) 
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.

On repairing CD section, playing a disc without the lid (CD), use 
Chuck Plate Jig.

LASER  DIODE  AND  FOCUS  SEARCH  OPERATION
CHECK
1.  Turn ON the [OPERATE] or [POWER] button and press [CD] 

button to CD position.

2.  Open the CD lid.
3.  Turn on S1001 with screwdriver, etc. as following fi gure.
4.  Press the [

N

 

X

] (CD) button.

5. Confi rm the laser diode emission while observing the object-

ing lens. When there is no emission, Auto Power Control cir-
cuit or Optical Pick-up is broken.

  Objective lens moves up and down three times for focus 

search.

When installing a new OP unit, be sure to connect the fl exible 
printed circuit board fi rst of all before removing the static electric-
ity prevention solder bridge by unsoldering. 
Remove the static electricity prevention solder bridge by unsolder-
ing after the fl exible printed circuit board has already been con-
nected. 
(Do not remove nor unsolder the solder bridge as long as the OP 
unit is kept standalone.)
