[Important Check Points for Good Servicing]
In this manual, procedures that must be performed during repairs are marked with the below symbol.
Please be sure to confirm and follow these procedures.
1. Product safety
Please conform to product regulations (such as safety and radiation regulations), and maintain a safe servicing environment by
following the safety instructions described in this manual.
1 Use specified parts for repair.
Use genuine parts. Be sure to use important parts for safety.
2 Do not perform modifications without proper instructions.
Please follow the specified safety methods when modification(addition/change of parts) is required due to interferences such as
radio/TV interference and foreign noise.
3 Make sure the soldering of repaired locations is properly performed.
When you solder while repairing, please be sure that there are no cold solder and other debris.
Soldering should be finished with the proper quantity. (Refer to the example)
4 Make sure the screws are tightly fastened.
Please be sure that all screws are fastened, and that there are no loose screws.
5 Make sure each connectors are correctly inserted.
Please be sure that all connectors are inserted, and that there are no imperfect insertion.
6 Make sure the wiring cables are set to their original state.
Please replace the wiring and cables to the original state after repairs.
In addition, be sure that there are no pinched wires, etc.
7 Make sure screws and soldering scraps do not remain inside the product.
Please check that neither solder debris nor screws remain inside the product.
8 There should be no semi-broken wires, scratches, melting, etc. on the coating of the power cord.
Damaged power cords may lead to fire accidents, so please be sure that there are no damages.
If you find a damaged power cord, please exchange it with a suitable one.
9 There should be no spark traces or similar marks on the power plug.
When spark traces or similar marks are found on the power supply plug, please check the connection and advise on secure
connections and suitable usage. Please exchange the power cord if necessary.
a Safe environment should be secured during servicing.
When you perform repairs, please pay attention to static electricity, furniture, household articles, etc. in order to prevent injuries.
Please pay attention to your surroundings and repair safely.
2. Adjustments
To keep the original performance of the products, optimum adjustments and confirmation of characteristics within specification.
Adjustments should be performed in accordance with the procedures/instructions described in this manual.
4. Cleaning
For parts that require cleaning, such as optical pickups, tape deck heads, lenses and mirrors used in projection monitors, proper
cleaning should be performed to restore their performances.
3. Lubricants, Glues, and Replacement parts
Use grease and adhesives that are equal to the specified substance.
Make sure the proper amount is applied.
5. Shipping mode and Shipping screws
To protect products from damages or failures during transit, the shipping mode should be set or the shipping screws should be
installed before shipment. Please be sure to follow this method especially if it is specified in this manual.

The PCM signals output from the DVD decoder or AD converter are input to this section, and their volume and sound quality
are digitally adjusted. At the output stage, after conversion from PCM to PWM, the signals are output to the Power stage.
In this section, timing is controlled so that the MOSFETs on the high and low sides will not be turned on simultaneously. The
voltage of the PWM signals are raised to drive the gates of the MOSFET, and the PWM signals to drive the speakers are
output from the MOSFET at the output stage. Detection and protection functions against short-circuiting of the output
signals and temperature exceeding the standard value are also provided.
The carrier elements, high-frequency signals that are unnecessary for these speakers, are eliminated. The signals passed
through the LPF will become sine-wave signals, as shown in the figure above.

The protection circuits for the Digital Amplifier are activated, following the specifications shown below. The error indication on
the FL display shows the reason a protection circuit was activated.
Upon diagnosis of the Digital Amplifier, refer to the specifications for the protection circuits here and the overview of the Digital
Amplifier circuitry.
1. Overview
The system microcomputer monitors the ports for shutdown requests (pin 23: SD_AB and pin 24: SD_CD) and the ports for
abnormal-temperature detection (pin 25: /OTW) of the Power Stage ICs (IC3201, IC3301, and IC3401). As soon as any
abnormality is detected, it shuts the unit down.
To notify the user of the possibility of a too high a volume, when the unit is turned on the next time, the volume level will be set
to 0, and an error message will be displayed on the FL display.
2. Ports on the system microcomputer to be used for detection
Pin 71: SHUTDOWN
Low voltage at this pin means overcurrent or voltage too low (= V+B27) at a Power Stage IC.
Pin 78: XOTW
Low voltage at this pin means the temperature at the Power Stage ICs exceeded 125 °C.
Note: As one Power Stage IC is provided with two channels, three Power Stage ICs (in total 6 channels) are mounted in
this unit. For abnormality detection, the unit implements a logical OR operation regarding these three ICs.
Therefore, which IC is abnormal cannot be known directly. To find which IC is abnormal, it is required to check the
PWM outputs (pins 35, 38, 47, 50) of the each power stage ICs (IC3201, IC3301, IC3401).
3. Detection timing
Start : Detection starts 500 ms after the PWRCONT port (pin 34) of the system microcomputer becomes active by your
pressing the STANDBY/ON key.
Finish : When the STANDBY/ON key is pressed again (when the power-off process starts).
4. Operation of the protection circuits
The following three protection circuits are activated when the conditions shown below are met:
Overcurrent detection 1: Indication on the FL display: OC ERR 1
Conditions: If the SHUTDOWN ports, which are monitored every 10 ms, become low 7 times in succession
Overcurrent detection 2: Indication on the FL display: OC ERR 2
Conditions: The PCONFIG ports (pin 58), which are monitored every 30 ms, become more than 2 Vrms more than 45 %
in one minute.
Abnormal temperature detection 1: Indication on the FL display: OVERTEMP
Conditions: If the XOTW ports, which are monitored every 10 ms, become low in succession for one minute.
Abnormal temperature detection 2: Indication on the FL display: OVERTEMP
(Prerequisite: The XOTW ports, which are monitored every 10 ms, become low three times in succession.)
Conditions: The above prerequisite is upheld, and the conditions for an overcurrent detection are met.
5. Process when the protection circuits are activated
The unit is shut down within 30 ms after abnormality detection then the volume level is set to 0.
The unit can be turned on immediately after the shutdown.
