1.4 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.

The part listed below is difficult to replace as a discrete component part.
When the part listed in the table is defective, replace whole Assy.

Notes about installation and pin number description of Power IC (IC1301: PA2032A)
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.
