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:

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.
Heat sink becomes hot areas. Be careful not to burn yourself.

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.

1.3 NOTES ON REPLACING PARTS C


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)
The Power IC, PA2032A used on the Tuner Amp Unit is a 25 pin IC.
D
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.
