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.

Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 ºC 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.

• For improvement of audio quality, many special screws and acetate tapes are used in this unit. Be careful when
disassembling/reassembling this unit, and be sure to restore the unit to its original state.

• As IC9011 (ROM) on the SERVICE MAIN Assy is fixed to the board with a special adhesive, it is not provided as a
service part. If replacement of IC9011 (ROM) is required, replace the entire SERVICE MAIN Assy.

• As the tray aluminum (VAH1456) and the tray panel base (VNK6455) are strongly adhered with double-back tape,
replace both parts when either needs to be replaced.
For attachment, adhere the tray aluminum (VAH1456) so that it is placed at the center of the tray panel base (VNK6455).

Items to be checked after repair (BD players)

To ensure the quality of the product after repair, check the recommended items shown below:

See the table below for the items to be checked regarding video and audio:

* (ex.) SC-LX81, SC-LX71.

Item to be checked regarding video Item to be checked regarding audio

Block noise Distortion

Horizontal noise Noise

Dot noise Volume too low

Disturbed image (video jumpiness) Volume too high

Too dark Volume fluctuating

Too bright Sound interrupted

Mottled color

Color disappearance

No. Procedures Item to be checked

1 Check the version of the firmware in Service mode.

The version must be the latest.
If the version is not the latest, update the firmware.

2

Check if all the symptoms pointed out by the customer have been
addressed. If a symptom pointed out by the customer is
attributable to a particular disc, that disc must be played back.

The symptoms in question must not be reproduced.
Video, audio, and operations must be normal.

3

Measure playback error rates at the innermost and outermost
tracks, by playing back the following discs:
BD-ROM test disc (GGV1308)
DVD test disc (GGV1025)

If the symptoms are related to the PQLS (Precision Quartz Lock
System), check PQLS operations.
(For checking PQLS operations, connection with an amplifier*
that supports the PQLS is required.)

The error rates must be 1.0e-3 or less.
This procedure can determine if the drive is degraded.

For checking PQLS operations, connect the player with the
customer’s amplifier then check that “PQLS” is lit in the display
window on the unit. (See [3] Front Panel Display in
“2.4 PANEL FACILITIES.”)

4 Check playback of a CD disc (track search). Audio and operations, such as a search, must be normal.

5

Check playback of a DVD disc (menu operations, title/chapter
search).

Video, audio, and operations, such as a search, must be normal.

6

Check playback of a BD disc (menu operations, title/chapter
search).

Video, audio, and operations, such as a search, must be normal.

7 Check the cabinet.

Check for any scratches or dirt that have been made or attached
on the cabinet after receiving the product for repair.

Before shipping out the product, be sure to clean the following positions by using the prescribed cleaning tools:

Position to be cleaned Cleaning tools

Pickup lenses Cleaning liquid : GEM1004
Cleaning paper : GED-008

The mark found on some component parts indicates the importance of the safety
factor of the part. Therefore, when replacing, be sure to use parts of identical
designation.
: The power supply is shown with the marked box.

Digital video signals from IC1001 are processed at IC9002 and IC9504 then output to IC5009, IC5509, and IC6301. If only either an
HDMI or analog video signal is output, check the reset and clock signals from around the relevant IC:
No HDMI MAIN video output available: Relevant IC: IC5009
No HDMI SUB video output available: Relevant IC: IC5509
No analog video output available: Relevant IC: IC6301
If no video signal is output, check the reset and clock signals from around IC9002 and IC9504.

 Pressing of the POWER key is detected by the IC4001 Submicrocomputer on the MAIN Assy.
The IC4001 then outputs a POWER_ON signal to the SYPS Assy.

 After receiving the POWER_ON signal, the SYPS Assy activates, secondary
Power[SW+12 V], setting it to ON.

 Communication between the R8A34019BG and the DDR2 SDRAM starts.

 Communication between the R8A34019BG and the FLASH_IC starts.

It takes about 1 minute to complete the startup process.

 The R8A34019BG (IC1001), the core LSI, starts up. {RS-232C connector CN1601,
log it to ON}

• Check the power ON sequence.

• Check in the log that the model number of the drive has been recognized.
Example: “PIONEER BD-** BDV-****, ATAPI CD/DVD-ROM drive”
If it is not recognized, check the power for the SPATA a n d ATA si gnals.

• According to the descriptions on the video block, check the power to
the relevant IC and for the reset/clock signals.

• Check that the ID No. and destination are set properly.

• Check that the drive operates properly.

• If an audio signal is not output from any of the analog audio connectors:
Check that power for each is supplied from AUPW to AUJB.
Also check the MCLK, BCK, and LRCK input signals between the MAIN and
AUJB Assys.

• If an audio signal is not output from a particular analog audio connector:
Check the ADATA0-3 input signals between the MAIN and AUJB Assys.
Check the digital input and analog output signals to/from the corresponding
DAC.

• Check that interlocked HDMI power On/Off functions properly.
If it does not function, check the signal between Pin 19 of the HDMI (MAIN)
connector and Pin 23 of IC4001.

• If the LEDs and video outputs cannot be turned on and off:
Check that the KEY0 signal between the MAIN and FLKY Assys responds to
pressing of the PureAudio key.

• If the audio power cannot be turned on and off: Check switching of the 12-V
power supply and RY_ON signal between the MAIN and ACSW Assys.
