Inserting the Region Code after replacing the Main PCB

NOTE
• After replacing the Main PCB and System Micom (IC23), the region code should be inserted.
• The unit will not work properly if you do not insert the correct region code.
• You must use the remote control

Select the "AUX" mode and then press the "Tuner Memory" button on the remote control for 4-5 seconds

You should see the “T-MODE” message display on the VFD. Press the “▼” direction button during this message.
NOTE: The “T-MODE” indicator on the VFD only appears for a very short time.

You can see “TEST - -” on the VFD. Insert the number “46” to select the Region Code.

After step (3), you can see “- - -” on the VFD.
Insert the Region Code (see Table on next page) corresponding to the model and area in which you reside in using the “0-9” buttons on the remote control. And then turn off the power.

In order to check if you inputted correctly, please do Number 1, 2, 3 again and then during “TEST - -” MODE insert number 47. After that, you can check the option code which you inserted. For example, you can see “000US5”. It means that you inserted region code “000” and the region is USA which supports 5.1CH Audio output. If it is “047EU2”, it means that you inserted region code “047” and the region is Europe which supports 2.1ch Audio output.

SONY BDP S370 - SERVICE MODE - BU AND BU ASSEMBLY REPLACEMENT

SONY BDP S370 - SERVICE MODE - BU and BU ASSEMBLY REPLACEMENT

BU & BU Assy Replacement Procedure.

Applicable to Sony BDP-BX37/S270/S370/S373/S470.

BU REPLACEMENT

Before BU Replacement.

* Enter Service Mode: Press < OPEN/CLOSE >, < PLAY >,< STOP > and plug in AC Power.

* Inside *Service Mode Menu Select [8] Drive.

* Inside *Drive Select [7] OP Check Menu.

* Inside *OP Check Menu Select [3] dIOP then press 'ENTER'.

* Specification Diop BD: 6mA DVD, CD: 9mA.  [If no - IOP out of specification need BU replacement > Optical Block Unit (BU) replace] {If Yes AC Power OFF}.

BU (Optical Block) Repair. BDP 5G (BDP-S370) series component structure is as same as conventional DVD Players.   However BD player requires precise read out functions and also secure contents Protection system.  Since above requirement, it is necessary to set/adjust BU data to EEPROM.

The following cases need Adjustments;

(1) Replace BU (MB is original)

(2) Replace MB (BU is original)

(3) Replace both BU and MB.

JIG Requirement

# Digital camera (recommend with macro mode)

# Barcode decoder (5GBUJIG) installed in JIG PC’s

# USB memory

# ESD work bench.

The servo adjustment procedure will be carried out during OP data writing.  There is no manual adjustment procedure. LD ON TIME history doesn’t carry over. Do not touch any optical block parts, Turn Table and during replacing. BD Laser diode is very sensitive.

BU Adjustment.

* Remove the defective BU from Loading Assy and also remove BU insulator (4pcs)

* Unpack new BU and take OP Data Barcode photo by camera.

* Assemble BU with Insulators to Loading Assy (tighten screw with 2kgf)

* Decode the OP Data Barcode photo using BDBUDEC.exe and save the test data to USB memory (File Name: BuData.txt)

* Enter Service Mode and insert USB memory to USB connector.

* Select [8] Drive > Select [1] Drive OP data Write > Select [2] Mode: 1 or 2 Press ENTER. {Mode: 1 BDP-BX37/S270/S370/S373/S470} {Mode:2 BDP-BX57/S570}

* IOP in specification > Turn AC Power OFF.

* Turn Power ON and check playback performance using BD,DVD & CD.

In case of BU assy replacement:

• OP related data for new assy is controlled by BU factory
• All of data is recorded into a barcode label
• The label is put on the assy
• Service parts will be followed
• In service, the data should be read out from problem assy
• The read data should be saved to new assy.

Fact finding:

• The label is “DATA MATRIX” format
• The number of data is 91 words
• The method of reading and saving is required when BU and main board are replaced.

• All of BU data on the barcode label is shot by digital camera in order to make a JPEG file of BU data.
• Application software in the PC makes digital data from JPEG file.
• The converted data is stored to USB memory.
• The USB memory is connected to BDP 5G unit.
• In service mode, there is a command to save the data from USB memory to board memory.

The application software will be a service jig with J parts number as service jig, and the recording media will be CD-R.
