Notes on chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be
damaged by heat.
Flexible Circuit Board Repairing
• Keep the temperature of 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.

adjustment to the MIN side fully (counterclockwise direc-
tion).
2. Connect a digital voltmeter to CN501 (TP) and CN601
(TP).
1P : ’side, 2P : ‘side
3. Turn ON the power button, and adjust RV501 and RV601
sothatthedigital voltmeterdisplay becomes22 mV± 2mV
within 5 seconds.
4. After the adjustment, turn OFF the power button.

EXPLODEDVIEWS
NOTE:
• -XX, -X mean standardized parts, so they may have
some difference from the original one.
• Items marked “*” are not stocked since they are
seldom required for routine service. Some delay
should be anticipated when ordering these items.
• The mechanical parts with no reference number in
the exploded views are not supplied.
• Hardware (# mark) list and accessories and pack-
ing materials are given in the last of this parts list.
The components identified by mark !
or dotted line with mark !are critical
for safety.
Replace only with part number
specified.
