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.
UNLEADED SOLDER
Boards requiring use of unleaded solder are printed with the leadfree mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with
the lead free mark due to their particular size)
: LEAD FREE MARK
Unleaded solder has the following characteristics.
• Unleaded solder melts at a temperature about 40 ˚C higher than
ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to
about 350 ˚C .
Caution: The printed pattern (copper foil) may peel away if the
heated tip is applied for too long, so be careful!
• Strong viscosity
Unleaded solder is more viscous (sticky , less prone to flow) than
ordinary solder so use caution not to let solder bridges occur
such as on IC pins, etc.
• Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.

SERVICING NOTES
1-1. Introduction
This document describes the “operation check for inspection (Test mode)” and “adjustment after board replacement for repair”.
In performing these works, connect this set to the PC via a USB cable and use the following tool.
Tool list
Ref. No. Tool name Part code Application
1 Service Tool 9140 (FD) J-2507-037-1 Board check (Test mode) and readjustment after board replacement
1-2. Board Repair
1. In performing the work, the set should be in a complete state (all components assembled).
2. Install the “OpenMG Jukebox” and “WMP7 Plug-in” (CD-ROM) in the PC in advance.
3. Do not start up other applications in the PC.
4. This set has the Test mode, and the use of exclusive application (Service Tool) on the PC side enables various function checks and the
voltage adjustment.
5. For the LOGIC board in this set, if either part listed in Table 1 is faulty, be sure to replace the board block. Also, when a part on the
POWER board was replaced or a combination of LOGIC board and POWER board was changed due to the board replacement,
perform 1-5 "Adjustment When Board was Replaced/Repaired".
6. The data in Table 1-2 have been written to the LOGIC board.
7. In repairing other than above parts, repair as usual.
Table 1-1.
Board name Ref. No
LOGIC board IC601, IC602, IC603, IC901

1-3. Operation Check for Inspection (Test Mode)
Precautions
1. Be sure to remove the battery from this set. (The power is supplied via USB cable)
Operating the set in the Test mode with the battery loaded could c lear necessary information.
2. If operation check was performed for inspection, execute “Play Info Initialize” in qd (see page 7) to return respective functions to
initial positions (see Table 1-5 on page 7). In such a case, record current position of each function before executing “Play Info
Initialize” in qd, if necessary.

Work procedure
Preparation:
1. Make sure that no battery is loaded in the set.
2. Start up the test mode “apollo_service.exe” of the service tool (J-2507-037-1) from the PC, and check that the following screen
appears.
3. Connect PC to this set with a USB cable. Check that the block 1 of the following screen “open”, and “1PC” is displayed on the LCD
of the set. (The block 1 will “close” if the set is disconnected again)
At this time, a sine wave is outputted from the headphone. Also, the model name is displayed in the block qd of the screen.

Note: If the block 1 does not “open”, the circuits in LOGIC board will be faulty. Audio signals are outputted from the reference signal in the DSP of
the set.

1. Audio Block Function Check
Clicking the UP or Down button in block 2 of the screen allows you to check with various output frequencies. Also, clicking the UP or
Down button in block 3 can check variations of volume. Clicking the L, Stereo, R, or Mute button in block 4 can change audio output
status.
2. Battery Threshold Value Reading and Measurement
Connect an exclusive USB cable to the set, and available battery threshold values (converted values corresponding to voltage values)
written to the set at the shipment will be displayed at 5. (See Table 1-3)
These threshold values are inherent values of the set, but if they were readjusted during the board repair, newly set threshold values
(converted values corresponding to voltage values) are displayed.
Table 1-3.

Voltage set value 1.00 V 1.15 V 1.25 V 1.35 V
Converted value (ref.) 320 368 400 432
Note: The threshold values (conver ted values corresponding to voltage values) are different every set.
3. LCD Test
Clicking FULL (full lit), COL1 (column 1), COL2 (column 2), or OFF (full off) in block 8 results in all ON, column 1 ON, column 2 ON,
or all OFF of the LCD on the set respectively.
4. CODEC Info Check
The CODEC programs and their versions written to the set can be checked. (block 9)

1-5. Adjustment When Board was Replaced/Repaired
When a part on the POWER board was replaced due to the repair or a combination of LOGIC board and POWER board was changed due
to the board replacement, perform 1. "Readjustment of Voltage for Battery Threshold Value" and 2. "Execution of Play Info Initialize" in
[Work Pr ocedure].
Replacing the board in this set will cause the status as shown in Table 1-4.
Table 1-4.
Board name Set status after board replacement
LOGIC board Music data and music information data stored in the set are cleared and not restored.
Precautions
1. Do not disconnect the USB cable in the midway of work.
2. If the operation on the PC side is not accepted during work, disconnect the USB cable and close the “apollo_service.exe” file, then
restart from the beginning.

Work Procedure
1. Readjustment of Voltage for Battery Threshold Value
Readjust the voltage through the steps given below.
(1) Start up the Test Mode "apollo_service.exe" in the Service Tool (J-2507-037-1) from the PC, and connect the set to the PC with an
excusive USB cable, and the following screen will appear.
At this time, the battery threshold values of available voltage written to the board are displayed at 5.

(2) Apply the specified set voltage in Table 1-5 to the battery terminals from regulated DC power supply.
Then, click the button 6, and the converted values (threshold values) corresponding to the applied voltage will be displayed. Under
this condition, click the button 7 and newly converted values (threshold values) will be written in the "AD Level" at 5.
(3) For each step in Table 5, apply the specified set voltage so as to write the converted value (threshold value).
Table 1-5.
Condition OFF Scale 1→2 Scale 2→3 Scale 3→4
Voltage set value 1.00 V 1.15 V 1.25 V 1.35 V
Converted value (ref.) 320 368 400 432
Note: The threshold values (conver ted values corresponding to voltage values) are different every set.
Precautions
1. The regulated DC power supply to be applied should have as less ripple as possible within the voltage accuracy +/–0.01 V.
2. Use properly calibrated measuring instrument for the measurement of voltage to be applied.
3. Do not solder directly the battery terminals when applying the voltage. Use clips, etc. to connect to the battery terminals.

3. Checking after Repair
(1) After work, check that the set operates normally through the operation in 1-3. “Operation Check for Inspection (Test Mode)” (see page
3).
(2) Make sure that the check-out and check-in can be made using the PC applications “OpenMG Jukebox” (CODEC programs “MP3” and
“ATRAC3”) and “Windows Media Player 7” (CODEC program “WMA”). Also, make sure that the checked out data can be played
normally.
Note: Do not start up the “OpenMG Jukebox” and the “Windows Media Player 7” simultaneously.
(3) For an installation and acquisition method of “Windows Media Player 7” (CODEC program “WMA”), refer to the follo wing instruc-
tion.
