SAFETY INFORMATION
This service manual is intended for qualified service technicians; it is not meant for the casual do-it-yourselfer.
A Qualified technicians have the necessary test equipment and tools, and have been trained to properly and safety 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 safety, 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
- Safety Precautions for those who Service this Unit.
When checking or adjusting the emitting power of the laser diode exercise caution in order to get safe, reliable
results.

Caution:
1. During repair or tests, minimum distance of 13 cm from the focus lens must be kept.
2. During repair or tests, do not view laser beam for 10 seconds or longer.

CAUTION:
USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE
SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.
C

CAUTION
CLASS 1M INVISIBLE LASER RADIATION WHEN OPEN. DO NOT VIEW DIRECTLY WITH OPTICAL INSTRUMENTS

WARNING!
The AEL (accessible emission level )of the laser power output is less than CLASS 1
but the laser component is capable of emitting radiation exceeding the limit for
CLASS 1.
A specially instructed person should do servicing operation of the apparatus.

Laser diode characteristics
Wave length:
DVD:660 nm to 670 nm
CD:780 nm to 800 nm
Focus lens on Maximum output:
CD:6.26 mW(Emitting period :9 sec.)
DVD:1.27 mW (Emitting period : unlimited)

Additional Laser Caution
E
Transistors Q1103 and Q1104 in PCB drive the laser diodes for DVD and CD
respectively. When Q1103 or Q1104 is shorted between their terminals,
the laser diodes for DVD or CD will radiate beam. If the top cover is removed
with no disc loaded while such short-circuit is continued, the naked eyes may
be exposed to the laser beam.

CAUTION
F
Danger of explosion if battery is incorrectly replaced.
Replaced only with the same or equivalent type recommended by the manufacture.
Discord used batteries according to the manufacture's instructions.

1. SERVICE PRECAUTIONS
1.1 SERVICE PRECAUTIONS
A

1. 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.
2. Be careful in handling ICs. Some ICs such as MOS type are so fragile that they can be damaged by electrostatic
induction.
3. 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.
4. To protect the pickup unit from electrostatic discharge during servicing, take an appropriate treatment
(shorting-solder) by referring to "the DISASSEMBLY" .
5. After replacing the pickup unit, be sure to skew adjustment.
B
6. During disassembly, be sure to turn the power off since an internal IC might be destroyed when a connector
is plugged or unplugged.
7. After the replacement of LS1 mecha, connect ACC and BUP, and then press RESET button.
->Some functions such as BOOK mark may not work normally.
8. Connector CN5001 in the monitor unit : When you remove the flexible from the CKS5951,
hold up the end of the flexible holddown part to remove it.
->There is a possibility of breakage of connector pin.
9. Connector CN5001 in the monitor unit : CKS5951 is a connector of both contact points.
If you insert the flexible inversely, there is a possibility of IC damaged because of unintended connection.
So please take care not to insert it inversely. If perchance you insert it inversely, you need to replace the unit.
10. The FFC styling between mother unit and DVD mecha (LS1) requires careful attention. Fold FFC to the
mecha side and style it. C
11. Eject lock
How to enter:Reset with [VOL-] key and [SOURCE] key pressed.
Summary:DISC EJECT behavior of built-in DVD mecha is prohibited
It is for DISC antitheft from the storefront display.
With or without DISC, the behavior of pressing EJECT key during the EJECT lock is as follows.
During grille closed
Press EJECT key -> Grille is opened.
*The key is valid at the point of being pressed (BEEP). To Leave the key makes grille opened.
During grille opened
Press EJECT key -> Grille is closed.
*The key is valid at the point of being pressed (BEEP). To Leave the key makes grille opened
Remarks: [Notes] EJECT lock is not unlocked by turning ACC ON or product reset. D
To unlock it, you need to operate keys as above.
For existing model (AVH-P9DVA), it is unlocked by turning ACC ON or reset.
12. Background display data is stored in IC5201. So, if you replace the IC, the user photo data will be lost.
13. Mechanism cover (Sheet: CNN3003) is NOT reusable. If you removed it, please replace it with the new one.
14. If the gasket (CNN2782) on the FM/AM tuner unit was damaged or lost, then the reception sensitivity would
be poor. So, replace it with the new one.

NOTE: When you remove the top case

NG OK

Don't put tweezers or something
into these holes to remove the top
case Use these holes to remove the top
case.

1.2 NOTES ON SOLDERING

A 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.

Compared with conventional eutectic solders, lead-free solders have higher melting points, by approximately 40 C.
Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 C in general, although
the temperature depends on the heat capacity of the PC board on which reworking is required and the weight of the tip of
the soldering iron.

Compared with eutectic solders, lead-free solders have higher bond strengths but slower wetting times and higher melting
temperatures (hard to melt/easy to harden).

B The following lead-free solders are available as service parts:
Parts numbers of lead-free solder:
GYP1006 1.0 in dia.
GYP1007 0.6 in dia.
GYP1008 0.3 in dia.
