• 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.

Do NOT use a soldering iron whose tip temperature cannot be controlled.

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).

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.

NOTES ON BTL DRIVE

As a signal to drive the BTL is output from the negative speaker terminal, DO NOT short-circuit between the negative
speaker terminal and ground, such as the chassis.
Do not short-circuit between the plus speaker terminal and ground, such as the chassis, too.

Case when this diagnosis is required :

When playback of any disc, including a test disc (DVD: GGV1025, CD: STD-905), cannot be performed

How to diagnose

In the case mentioned above, degradation of the laser diodes (LDs) mounted on the Pickup PCB is suspected.
Measure the voltage between the two ends of one of the resistors mentioned below.

Measure the voltage between the two ends of R322 or R325 on the 08 DVDM
Assy. If the voltage is 0.4 V or higher, the 650-nm LD is degraded.

No playback of a DVD :

Measure the voltage between the two ends of R321 or R326 on the 08 DVDM
Assy. If the voltage is 0.4 V or higher, the 780-nm LD is degraded.

No playback of a CD :

If the measurements show degradation
of an LD, replace the DVD MECHA
Assy.

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 77: SHUTDOWN
Low voltage at this pin means overcurrent or voltage too low (= V+B27) at a Power Stage IC.

Pin 79: 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 84) 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: Indication on the FL display: OC ERROR
Conditions: If the SHUTDOWN ports, which are monitored every 10 ms, become low 7 times in succession

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.

Abnormal temperature detection 3: Indication on the FL display: OVERTEMP
Conditions: The PCONFIG ports (pin 21), which are monitored every 30 ms, become more than 2 Vrms more than 45 %
in one minute.

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.

• BREAKDOWN CATEGORY: Depends on the error displayed during POWER ON.

[Only for models without DSP]

• When function is switched to LINE 2 (LINE for areas beside Europe, Japan), SURROUND mode will switch to
X-STEREO (5CH STEREO) just for the TEST MODE. (NORMAL MODE: 2CH STEREO)
At this point, sound checking can't be done using HP.
(HP operation cannot be guaranteed for X-STEREO (5CH STEREO))
All functions, other than LINE2 (LINE for areas besides Europe) can be used for sound checking using HP.

[Models with DSP]

• Change the ADV mode to X-STEREO (5 ch STEREO) mode for multi CH output.

Protect circuit is operating.

1. Depending on the different power supply abnormalities, V+10, V+5, V+3R3 short-circuit occured or V+10, V+5, V+3R3
has exceeded the stipulated standardized values.

2. In the system microP (PDC175A, PDC176A) somewhere, the XPROTECT line has either shorted to ground or has
been disconnected.

1. Depending on the power supply abnormalities, V+6R8, V+5V, V+3 short-circuit occured or V+6R8, V+5V, V+3 has
exceeded the stipulated standardized values.

2. In the system microP (PDC175A, PDC176A) somewhere, the VDET line has either short to ground or disconnected.

1. Communication line to the EEPROM could either be disconnected or short.

2. The EEPROM IC itself could be faulty.

• If error display does not come on again when POWER ON in the NORMAL MODE, this could mean that the speaker
terminal is short.

• If error display comes on, the following conditions are some possibilities:

1. In the AMP Block, either one or more of the digital amp IC has broken down.

2. Short-circuit occurred somewhere between the faulty IC(s) and speaker terminal.

3. The XSD SHUTDOWN line has either short to ground or disconnected somewhere between the faulty digital amp IC
and system microP (PDC175A, PDC176A).

O C E 1RR

• The error is mainly caused by the short circuit at the POWER SUPPLY Unit .

• The error will also occur when V+BSW is too low.
