Additional Laser Caution 1. Laser Interlock Mechanism · Loading switch (S101 on the LOAB Assy) is used for interlock mechanism of the laser. When this switch turned ON in SW2 (CLOSE) side (OPEN signal is 0 V and CLOSE signal is 3.5 V), a laser becomes the status which can completely oscillation. Furthermore, the laser completely oscillates in the disc judgment and disc playback. When player is power ON state and laser diode is not completely oscillating, 780 nm laser diode is always oscillating by half power. · Laser diode is driving with Q307 (650 nm LD) and Q308 (780 nm LD) on the DVD MAIN Assy. Therefore, when short-circuit between the emitter and collector of these transistors or the base voltage is supplied for transistors turn on, the laser oscillates. (failure mode) · In the test mode , there is the mode that the laser oscillates except for the disc judgment and playback. LD ON mode in the test mode oscillates with the laser forcibly. The interlock mechanism mentioned above becomes invalid in this mode. 2. When the cover is open, close viewing through the objective lens with the naked eye will cause exposure to the laser beam. : Refer to page 25.

1. SERVICE PRECAUTIONS
1.1 NOTES ON SOLDERING
· 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.

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.

5.4 SPECIFICATIONS FOR THE PROTECTION CIRCUITS FOR THE DIGITAL AMPLIFIER
A
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.
B
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 (35, 38, 47, 50 pin) of the each power stage ICs (IC3201, IC3301, IC3401).
C
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).
D
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 (21-pin), which are monitored every 30 ms, become more than 2Vrms more than 45% in one minute.
E
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.

5.5 PASS/FAIL TEST PROCEDURE OF HDMI TRANSMITTER IC
A
1
In a case where the HDMI video signal is not output
No Malfunctions are caused around IC201 BE IC. Yes
Is the analog video signal output?
B
Check if the HOME MENU or VCD playback picture is displayed when this unit is connected to a PC monitor equipped with a Yes DVI input. Purpose: To check if the HDMI output line, including the terminal, is in failure. (An HDMI <-> DVI conversion cable is required for checking.) No
Check if the initialization process for HDCP, etc. is OK by connecting this unit with a Pioneer Plasma Display equipped with an HDMI input. NG OK The customer's monitor may not be compatible with this unit. Confirm the name of manufacturer and model of the monitor, and get a specific description of the failure. Then look for an identical case in a collection of past cases, or consult the design section. In some cases, upgrading the software or firmware for both the DVD player and the monitor will solve the problem. The HDMI transmitter IC (HDCP process block) may be in failure. Change IC201 or IC931.
C
Pass/fail test of BE IC (IC201: DVD MAIN Assy) Conduct proving of R264, R265, R267 and R271 (33 ohms x 44 set), and R266 (27 MHz clock) with an oscilloscope to check whether each signal varies in amplitude between H (3.3 V) and L at reproducing VCD, and whether 27 MHz clock is correctly output. NG Malfunctions are caused around IC201 BE IC or in IC201.
OK
Malfunctions are caused in HDMI IC (IC931 : DVD MAIN Assy) or in the output line between IC931 and CN931. In this regard, the frequency is around 1 GHz at the CLK and DATA line between IC931 and CN931, which makes it difficult to observe the waveform by a general oscilloscope. Check the connection with the HDMI connector and the HDMI cable, as well.
D
2
In a case where the HDMI audio signal is not output
No Change mode.
The initial setting provides no sound. Has HDMI sound been changed in STAND-BY MENU? Yes Is a correct signal found by proving the output of 216 pin and 211 pin of IC201, R248 (HSPDIF) and R240 (HCLK : 22/24MHz clock) with an oscilloscope? Yes
E
No
Malfunctions in IC201.
Is the signal as described above sent to the input of IC931? Yes Is the HDMI image output? No Malfunctions are caused in the output line between IC931 and CN931. Check the HDMI connector, as well.
No
Malfunctions around IC931.
Yes
Malfunctions in IC931.

5. Operations during Service Test Mode
· Basically, operations in Service Test mode are the same as in Normal mode. However, to indicate that the unit is in Service Test mode, the following are displayed when the functions are changed: [Functions]
DVD/CD USB TUNER LINE1 LINE2
A
[FL display]
D V D U S B T X L N 1 L N 2 S E R V S E R V S E R V S E R V S E R V
· When the function is set to LINE2, the Surround setting is fixed to X-STEREO (5 CH STEREO), which is only for Service Test mode. (In Normal mode, it is fixed to 2 CH STEREO.) In such a case, do not check the sound through the headphones, because headphone operation with X-STEREO (5 CH STEREO) is not guaranteed. If you wish to check the sound through the headphones, use a function other than LINE2.
B
6. Failures
· Depending on the types of errors, one of the following error messages will be displayed when the unit is turned on:
P R T C T E
A protection circuit was activated: 1. The V+10, V+5 or V+6R8 was short-circuited (See the protection circuit on "10.2 DVD MAIN ASSY (2/5)"), or the value at V+10, V+5, or V+6R8 exceeded the standard value because of an abnormality in its power section. 2. The XPROTECT port (22-pin) line up to the system-control computer (IC5501) was short-circuited by grounding or was broken.
D V D P R T C T
C
Abnormality in the DVD section 1. The V+5V, or V+3 was short-circuited, or the value at V+5V, or V+3 exceeded the standard value because of an abnormality in its power section. 2. The VDET port (17-pin) line up to the system-control computer (IC5501) was short-circuited by grounding or was broken. (See VDET circuit on "10.2 DVD MAIN ASSY (2/5)")
E E P E R R
1. Breakage or short-circuiting of the communication line between the microcomputer (IC5501) and the EEPROM (IC5502) can be suspected. 2. A failure in the EEPROM (IC5502) can be suspected.
OC OC E R R E R R 1 2
D
· If "OC ERR 1, 2" is not displayed when the unit is turned on in Normal mode, short-circuiting of the speaker terminals can be suspected. (It causes speaker cable "+", "-" short.) · If "OC ERR 1, 2" is displayed again when the unit is turned on in Normal mode, the following causes can be suspected: 1. One or more of the ICs among the three digital amplifier ICs (IC3201, IC3301, and IC3401: TAS5122DCA) on the DAMP Assy is in failure. 2. The line between one of the above digital amplifier ICs and the speaker terminals is short-circuited. 3. The SHUTDOWN port (77-pin) line from one of the above digital amplifier ICs to the system-control computer (IC5501) is short-circuited by grounding or is broken.
O V E R T EMP
· If "OVERTEMP" is not displayed when the unit is turned on in Normal mode, the unit is normal. The protection circuit was activated because the temperature at the three digital amplifier ICs (IC3201, IC3301, and IC3401: TAS5122DCA) had become too high. Because it is likely that this was a temporary temperature rise, lower the volume of the speakers. · If "OVERTEMP" is displayed again when the unit is turned on in Normal mode, the following causes can be suspected: 1. One or more of the ICs among the three digital amplifier ICs (IC3201, IC3301, and IC3401: TAS5122DCA) on the DAMP Assy is in failure. 2. The XOTW port (79-pin) line from one of the above digital amplifier ICs to the system-control computer (IC5501) is short-circuited by grounding or is broken.

8.2 ID NUMBER AND ID DATA SETTING
A
Caution: For the DVD players compatible with DVD-RW, for playback of a DVD-RW disc (CPRM) and for the DVD players possessing HDMI output, for HDCP process, it is necessary that an individual ID number and ID data are set for each player. If the ID number and ID data be not properly set in the manner described below, future operations cannot be guaranteed. The ID number is written on the yellow label at the rear panel of the player. If there is no yellow label, before downloading FLASH ROM, take note of the ID number set following the procedures outlined in "ID Number Confirmation Mode" on the next page. Note: Enter ID numbers while the unit is in Stop mode so that the values set will be immediately written to the flash ROM. Setting an ID number or ID data is required in the following case: If "No NUM" or "NO DATA" is displayed on the FL display for a few seconds immediately after the power to the player is turned on or during Stop mode. JIGS AND MEASURING INSTRUMENTS
5 After entering all 9 digits, if you press the SEARCH key, the unit unconditionally sets the input number as the ID number. Then the unit automatically enters Player's Data Input Mode. (The SEARCH key is not accepted after all 9 digits have been entered.)
