Flexible Circuit Board Repairing

• Keep the temperature of the soldering iron around 270 ˚C during repairing.

• Do not touch the soldering iron on the same conductor of the circuit board (within 3 times).

• Be careful not to apply force on the conductor when soldering or unsoldering.

Notes on chip component replacement

• Never reuse a disconnected chip component.

• Notice that the minus side of a tantalum capacitor may be damaged by heat.

Service Tool List

Ref.No. Tool Name Part No. Usage

1 Service Tool 9100 (CD-ROM) J-2500-377-1 Board Test

In replacing the following parts, replace the board altogether.

Board Name Ref. No.

Main Board IC201, 202, 203, 601, 901 Sub Board IC803

Precautions on repairing the main board:

1. IC202 and 203 store music data. These parts are special packages called TCP, and they are very sensitiv e to a shock. Therefor e, do not touch these parts or leads directly, or do not give a shock.

2. IC601 and 901 are CSP packages. Do not give a shock to these parts.

3. The ground pattern around the board is in a height restriction “0” zone. Do not put a solder in this zone.

Precaution on repairing the sub board:

1. Special ID has been written to the IC803. When this part seems to be faulty, replace the sub board altogether.

Additional precaution:

1. This set can cooperate with PC using the ID written to the set. After repaired, confirm the connection and check in/check out using the “OpenMg JukeBox”.

1-2. Board Replacement

This set consists of two boards, Main and Sub, and the contents of respective boards are as shown in Table 1. Table 1

Board Name Contents

Main board Music data, Battery adjustment value, Equalizer

initial value, CODEC program

Sub board ID/IK, Music information on Main board

If either board was replaced during repair, the music data in Main board do not match the music information in Sub board, and therefore be sure to perform the following checking and work. Replacing the board causes the conditions as listed in Table 2.

Table 2

Replaced Board Conditions

Main board Music data, if stored in set, are cleared. How ever, the data can be recovered

by connecting the set to the same PC as that used when check-out was executed. (Supposed check-in)

Sub board Music data, if stored in set, are cleared, same as in the Main board replacement.

Also, the data are not recoverable because ID/IK are changed.

Preparation

Replacing the board causes the music data in Main board and the music information in Sub board to be unmatched, thus requiring the music data in Main board and the music information in Sub board to be initialized. T o initialize these data, perf orm the following checking and work. In performing the work, set the boards in position. Also, do not load the battery (the power is supplied through the USB cable).

1-1

Procedure

1. From the PC, start “VMC_TEST” (J-2500-377-1) of the service tool.

2. Confirm that the following screen appears.

3. Connect the set with an exclusive cable. At this time, make sure that “Open” is displayed at the part 1 of the following screen. The “Open” display means that the set is connected to PC normally (“Close” is displayed when the set is disconnected). Also, confirm that the “PC” is displayed on the LCD of the set.

1-2

4. Click the “Press Button” at the part 2 of the following screen.

5. Check that, after several seconds, “Complete!” is displayed in the “Result” field at the part 3 of the following screen. Also, check that “1 PC” is displayed on the LCD of the set.

Precautions

1. Never disconnect the cable during work.

2. If the PC is hung up during work, disconnect the cable and close the “VMC_TEST” once, and then retry from the beginning.

3. After the work, make sure that the check-in and check-out can be executed using the PC application “OpenMG Jukebox”. Also, confirm that the checked out data can be played normally.

1-4. Test Mode

This set has the T est mode in the microcomputer , and the use of e xclusive application softw are on the PC side can check various functions.

Preparation

1. From the PC, start the T est mode “Vmo_Check.e xe” (J-2500-377-1) of the sevice tool, and confirm that the following screen appears.

2. Connect the set with exclusive cable (the po wer for the set is supplied from USB), then check that the part 1 on the following screen is “Open”, and also “1 PC” is displayed on the LCD of the set. (Part 1 becomes “Close” if disconnecting the cable again.) At this time, a sine wave is generated from the headphone.

Supplement: If the part 1 does not become “Open”, the USB of the set will be faulty.

Also, audio signals are outputted from the reference signal in the DSP of the set.

Description of Service Mode Operation

1. Checking the Functions of Audio Section Clicking the Up/Down at part 2 of the screen can change the output frequency. Also, clicking the Up/Down at part 3 can change the volume. Clicking the L/Stereo/R/Mute at part 4 can change the output.

2 3

2. Battery Threshold Value Reading and Measurement When the Test mode is selected, the threshold values for the remaining battery capacity written in the set are displayed at the part 5. These values are adjusted values at the shipment, and inherent data. The threshold values are provided separately for the PLAY and for the IDLE; values are at scale 3→4, scale 2→3, scale 1→2, and OFF from the right to left. Standard threshold value is given with “1024/1.8 × Battery T erminal Voltage”, and the battery terminal voltages to respective threshold values are as follows.

OFF Scale 1→2 Scale 2→3 Scale 3→4

At idle 1.05 V 1.13 V 1.20 V 1.31 V At play 1.00 V 1.10 V 1.18 V 1.30 V

Click the part 6, and the calculated value corresponding to the voltage will be displayed if the voltage is applied to the battery terminals. For example, if 1.2 V is applied to the battery terminals, approximate 680 is displayed.

3. LCD Test Clicking the FULL/COL 1/COL 2/OFF respectively at part 7 can cause the LCD on the set to turn on full LCD, column 1, column 2, or turn off LCD.

4. Flash Memory Read/Write Check Clicking the part 8 can check the read/write of the flash memory. If normal, “Success” is displayed.

5. CODEC Info Check The CODEC program versions written in the set can be checked, and they are displayed when the Test mode is selected (part 9). At the shipment, they are as follows (these values vary when the progr ams are updated).

Name Version

CODEC1 AT3 8 CODEC2 MP3 7 CODEC3 blank 0 CODEC4 blank 0

1-5

Supplement: As the CODEC Info has been written in the EEPROM on the Sub board, it may be said that the EEPROM operation is OK,

if the information is displayed normally.

6. Firmware Info Check The microcomputer program version and the flash memory capacity can be checked, and they are displayed when the Test mode is selected (part 0). At the shipment, they are as follows (these values var y when the program is updated).

Ver (microcomputer version) 38 Flash Size 63766528

7. Key Check Click the part qa with any key on the set pressed, and “ON” will be displayed in the field corresponding to that key.
