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.
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.
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK
OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic
breakdown because of the potential difference generated by the
charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic breakdown 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.

CHUCK PLATE JIG ON REPAIRING
On repairing CD section, playing a disc without the lid (CD), use
Chuck Plate Jig.
• Code number of Chuck Plate Jig: X-4918-255-1
SECTION 1
SERVICING NOTES
LASER  DIODE  AND  FOCUS  SEARCH  OPERATION
CHECK
1. Turn ON the POWER button and press FUNCTION button to
CD position.
2. Open the lid (CD).
3. Turn on S801 with screwdriver, etc. as following figure.
4. Press the CD  N X  button.
5. Confirm the laser diode emission while observing the objecting
lens. When there is no emission, Auto Power Control circuit or
Optical Pick-up is broken.
Objective lens moves up and down three times for focus search.

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 viscous (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.
