SAFETY INFORMATION
CAUTION
A
This service manual is intended for qualified service technicians; it is not meant for the casual do-it-yourselfer.
Qualified technicians have the necessary test equipment and tools, and have been trained to properly and safely repair
complex products such as those covered by this manual.
Improperly performed repairs can adversely affect the safety and reliability of the product and may void the warranty.
If you are not qualified to perform the repair of this product properly and safely, you should not risk trying to do so
and refer the repair to a qualified service technician.
Where in a manufacturer's service documentation, for example in circuit diagrams or lists
of components, a symbol is used to indicate that a specific component shall be replaced only
by the component specified in that documentation for safety reasons, the following symbol shall
be used:
B
CAUTION
Danger of explosion if battery is incorrectly replaced.
Replaced only with the same or equivalent type recommended by the manufacturer.
Discord used batteries according to the manufacturer's instructions.

1. SERVICE PRECAUTIONS
1.1 SAFETY PRECAUTIONS
A
You should conform to the regulations governing the product (safety, radio and noise, and other regulations), and
should keep the safety during servicing by following the safety instructions described in this manual.
Please keep the distance of more than 13 cm from focus lens for safety when you check pickup and make adjustment,
and do not look straight at Laser Beam for more than 10 seconds.
1.2 NOTES ON DISASSEMBLY / ASSEMBLY
Before disassembling the unit, be sure to turn off the power. Unplugging and plugging the connectors during power-on
mode may damage the ICs inside the unit.
Please be sure to conduct line process to original status if you make assembling after repair.
B
1.3 NOTES ON REPLACING PARTS
Be careful in handling ICs. Some ICs such as MOS type are so fragile that they can be damaged by electrostatic
induction.
Please be careful of not to apply static charge onto integrated circuits, etc, when you conduct repair work.
Especially, please use soldering iron with its tip grounded.
Also, please use a pair of tweezers with static charge protection capability if there is the possibility of contacting to
device terminals, and avoid the use of metal-made tweezers.
Notes about installation and pin number description of Power IC (IC301: PA2032A)
C The Power IC, PA2032A used on the Tuner Amp Unit is a 25 pin IC.
The same PCB of the Tuner Amp Unit is used for other models that use a 27 pin IC, too.
So, the PCB has lands for a 27 pin IC.
When you replace the Power IC, install the Power IC onto 25 pins (2- 26 pin) located in the center of 27 pins for IC301.
Therefore, when you check the Power IC on the schematic diagram and the PCB connection diagram, you have to pay
attention as follows.

Notes on soldring
F
For environmental protection, lead-free solder is used on the printed circuit boards mounted in this unit.
Be sure to use lead-free solder and a soldering iron that can meet specifications for use with lead-free solders for
repairs accompanied by reworking of soldering.
