Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous
radiation exposure.

•

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.

•

Never reuse a disconnected chip component.

•

Notice that the minus side of a tantalum capacitor may be
damaged by heat.

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.

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 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.

1. Turn ON the [POWER] or [OPERATE] button and press [CD]

button to CD position.

2. Open the CD lid.
3. Turn on S801 with screwdriver, etc. as following figure.
4. Press the  N X  (CD) 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.

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