Chapter One About Maintenance
1.1 Safety precautions
1.1.1 Precautions for antistatic
Movement and friction will both bring static electricity which causes serious damages to integrated
IC. Though static charge is little, when a limited quantity of electric charge is added to large-
scaleintegrated IC, as the capacitance is very small in the meantime, now the integrated IC is very much
easy to be struck through by static electricity or the performance will decrease. Thus static electricity
prevention is of extraordinary importance. The following are several measures to prevent static
electricity:
1. Use a piece of electric conduction metal with the length of about 2 metres to insert into the earth,
and Fetch the lead wire from the top of the surplus metal and connect to the required static electricity
device. The length and depth of the metal embedded under the earth should be determined according to
the wettability of the local soil. For humid places, it may be shorter, and longer and deeper for dry places.
If possible, it can be distributed and layed in terms of “#” shape.
2. On operating table-board, the antistatic table cushion should be covered and grounded.
3. All devices and equipments should be placed on the antistatic table cushion and grounded.
4. Maintenance personnel should wear antistatic wrist ring which should be grounded.
5. Places around the operating position should also be covered with electric conduction cushion or
Painted with antistatic paint.
1.1.2 About placement position
1. Audio power amplifier cannot be installed in places with high temperature and humidity.
2. Positions for placement should be stable and secure.
1.2 Maintenance method
1.2.1 Visualized method
Directly view whether abnormalities of collision, lack of element, joint welding, shedding welding,
rosin joint, copper foil turning up, lead wire disconnection and elements burning up among pins of
- 1 -
Page 6
Elements appear. Check power supply of the machine and then use hands to touch the casing of part of
elements and check whether they are hot to judge the trouble spot. You should pay more attention when
using this method to check in high voltage parts.
1.2.2 Electric resistance method
Set the multimeter in resistance position and test whether the numerical value of resistance of each
point in the circuit has difference from the normal value to judge the trouble spot. But in the circuit the
tested numerical value of resistance is not accurate, and the tested numerical value of integrated IC's
pins can only be used for reference, so the elements should be broken down for test.
1.2.3 Voltage method
Voltage method is relatively convenient, quick and accurate. Set the multimeter in voltage position
and test power supply voltage of the player and voltage of a certain point to judge the trouble spot
according to the tested voltage variation.
1.2.4 Current method
Set the multimeter in current position and test current of the player of a certain point to judge the
trouble spot. But when testing in current method, the multimeter should be series connected in the
circuit, which makes this method too trivial and troublesome, so it is less frequently used in reality.
1.2.5 Cutting method
Cutting method should be combined with electric resistance method and voltage method to use.
This method is mainly used in phenomena of short circuit and current leakage of the circuit. When
cutting the input terminal voltage of a certain level, if voltage of the player rises again, it means that the
trouble lies in this level.
1.2.6 Element substitution method
When some elements cannot be judged good or bad, substitution method may de adopted directly.
1.2.7 Comparison method
A same good PC board is usually used to test the correct voltage and waveform. Compared these
data with those tested through fault PC board, the cause of troubles may be found.
Through the above maintenance method, theoretical knowledge and maintenance experience, all
difficulties and troubles will be readily solved.

Figure 3.2.1.1 Flash circuit schematic diagram
2. Working principle: Flash Memory is the storage unit of the player, all MP3 and waveform files
should be stored in FLASH. Flash module is composed of FLASH chip TC58512FT and peripheral circuit
to finish internal files’s working of read, write and delete. 3.3V voltage circuit provides 3.3V voltage for
Flash working. R53 and R54 is pull up resistor of /CE1 and CE2, R52 is pull up resistor of R/B1, R61 is
the pull down resistor of /WP,Vcc is power supply pin of FLASH, /CE is chip selection signal, high level is
effective, VCC33 provides 3.3V voltage and FLASH begins to work. /RE, /WE are read effective and
write effective signal end respectively to control read and write function of FLASH. I/O1 - I/O8 are 8 data
lines to complete the exchange of FLASH and external data to realize functions of write, delete and edit
of MP3.
When MP3 is powered on, 3.3V voltage supplies power for Flash through Vcc, /CE inputs 3.3V high
level signal and Flash begins to work effectively. When MP3 is playing musical and recording files, /RE

Pin VIN is ISL6294 power input pin, that is input end of USB 5V power; BAT is output pin of ISL6294, that
is input end of lithium-ion battery; /CHG is charge state indication end; when /CHG is low level, it means
machine is in charge, or else it means the charge finishes; IMIN is min charge current setup end, that is,
when charge current is lower than the current set by this end, charge is terminated. Setup of min charge
current is realized through selecting external resistor R2. The relation between min charge current /
MIN
and R2 is shown as follows:
(mA)
- 18 -
Page 23
From the above, we know that min charge current is 20 mA.
IREF is charge current setup end and ISL6294 uses this reference current to charge lithium battery.
Relation between charge current I and external resistor is shown as follows:
REF
Triode Q9 in circuit is used as charge current selection. When users use computer to charge battery,
PNX0102 outputs Sl6294, which is low level, Q9 cuts off and R11 is connected into circuit. From the
above, IREF is about 100 mA; when users use charger to charge battery, PNX0102 outputs ISL6294,
which is high level, Q9 is saturated on, R2 and R11 are connected parallel into circuit. From the above,
IREF is about 200m A. The reason for this design is that USB jack of some computers (for instance,
some PC) cannot provide large current to charge battery.

2. Working principle: battery protection circuit is mainly composed of battery protection IC S8261
and internal dual N groove MOSFET ECH8601. S8261 is the protection IC of the lithium-ion polymer
chargeable battery of internal high precision voltage detect circuit and delay circuit. DOUT and COUT
pin are over discharge (when lithium battery voltage is lower than 2.4V) protection output end and over
charge (when lithium battery voltage is higher than 4.2V) protection output end. The two pins are high
level when working normally; MOSFET is on and lithium battery voltage outputs to the player through
protection board; when in protection, the two pins output low level to control MOSFET to cut off power.
Over current detect (short-circuit protection) is fulfilled through the control of DOUT and COUT output by
V- pin when detecting short-circuit state; when battery is in short-circuit, voltage on V- external resistor
R1 will have a sudden change, V- detects that voltage on R2 increases immediately and then outputs to
control DOUT and COUT and outputs low level at the same time to control MOS tube to cut off battery to
protect battery.

and whether screen has display and result is that there is no display; take down machine and check
power supply 3.3V and 1.8V, we find that 3.3V decreases to 0.6V; use power adapter to suppl power,
input 5V is normal, charge enable end is high level and it is also normal; observe carefully and find that
pin 2 of U3 (TPS79301) has false welding; after weld again, trouble is removed.
[ Example 2 ] Symptom: machine cannot be switched on
Description: press ON button, screen has no display and headphone has no output.
Analysis and troubleshooting: firstly make sure whether machine cannot be switched on or power
not on; connect with power adapter or computer and check whether screen displays normally; connect
with power adapter and charge can display, which means that power and rear stage circuit working is
normal; power on/off circuit, through a light touch switch Sw1, forms loop after closing; signal produces
and enters U6 (PIC10F200) pin 1 high level to make pin 4 produce a high level to give power an enable
end signal to control whether the whole circuit works; test SW1 switch, press SHUT and check whether
it is on; when testing, we find that Sw1 has false welding; after welding again, trouble is removed.
[ Example 3 ] Symptom: cannot connect with computer
Description: no response and no OSD after connecting with computer
Analysis and troubleshooting: firstly make sure whether charge and power on are normal and the
result is normal; use diode level of multimeter to test the resistance to ground of D+, D- data signals in
USB terminal position and it should be close to several hundred ohm, but we find that D+ resistance
value is normal, D- resistance value is infinite and USB terminal has false welding; after welding again,
trouble is removed.
[ Example 4 ] Symptom: noise appears when tuning
Description: noise appears when tuning.
Analysis and troubleshooting: firstly judge whether tuning components or common part has trouble,
whether one side of headphone has sound when listening, and the result is normal; then switch to tuning
- 25 -
Page 30
State, search radio station automatically, tuning is normal, which means power supply, data and clock
are normal; we remote external interference, receive the nearest local radio station and check whether it
is clear, and the result shows noise still exists; circuit that causes noise is high frequency tuning and
mixed frequency part; carefully check and find that pin 37 of tuning U12(TEA5767HN)is false welding;
weld again and trouble is removed.
[ Example 5 ] Symptom: noise appear when playing
Description: headphone output noise when playing
Analysis and troubleshooting: if there is noise when playing, it is BGA that has trouble, for playback
and other functions are all normal, only there is noise, so it is necessary to analyse whether decode [art
or rear stage causes this trouble, when playing 1KHZ standard signal, there should be sine wave signals
and not any noise; test P3, N3 waveform close to BGA, so we judge that it is BGA that has trouble; after
changing it, trouble is removed.
[ Example 6 ] Symptom: no OSD
Description: screen has no display
Analysis and troubleshooting: firstly confirm whether trouble lies in power or screen itself; power on
and listen to the sound and sound s normal, so it is preliminarily judged that power supply 3.3V and 1.8V
are both basically normal. Firstly test voltage on two ends of L2 and it is about 4.3V, which is basically
normal; then test voltage on two ends of D8 and find that anode has no 13V voltage, take down display
screen and there is still no; check input end voltage and enable voltage and they are basically normal,
then check FB end voltage of feedback pin and it is obviously low, EN enable end has false welding,
after welding again, trouble is removed.
[ Example 7 ] Symptom: screen has mosaic
Description: display screen has mosaic and display has disorder
Analysis and troubleshooting: this troubleshooting is the same with that of no screen display, with
the difference is that power supply is normal; firstly confirm whether the screen itself has trouble or
circuit has trouble, change display screen and trouble still exists, then use oscillograph to test the 8-digit
number of OLED screen and find that flat cable holder of display screen has false welding, after welding
again, trouble is removed.
[ Example 8 ] Symptom:
Description:
Noise when playing recording files
Noise when playing recording files
Analysis and troubleshooting: schematic diagram of record circuit is shown in the figure, it is mainly
composed of microphone and microphone power bias circuit, MIC switches the external voice signals
recorded into electric signals, through being coupled by C71, output to ADC circuit of PNX0102 and form
- 26 -
Page 31
WMA files through software coding to save in Flash.When repairing this kind of machine, firstly play files
and check whether there is noise and there is no; check recording circuit and power supply is normal;
when recording, use oscillograph to test C71 and there is noise interference, after changing MIC, trouble
is removed.
[ Example 9 ] Symptom: cannot connect with computer
Description: no display after connecting with computer and disk cannot be found
Analysis and troubleshooting: if software program is incorrect or lost, machine may probably not be
switched on or machine failure will happen; when this trouble appears, please fresh the software firstly;
firstly check whether software upgrading is available and then down load software program; after
upgrading software, trouble is removed.
[ Example 10 ] Symptom: cannot charge
Description: charge mode can display but in fact charge function is not available
Analysis and troubleshooting: charge mode and charge can both display but the player cannot be
fully charged; after 3 hours, unplug power adapter and power on, low battery charge displays and then
power off automatically; you may enter charge mode and there is charge indication, which means there
is power input,
BAT and CHG are normal, so we should consider charge control pin, check IMIN current
control end, when current of this pin is very small, charge stops; R11 has false welding; after welding
again, trouble is removed.

3.5.3 Function introduction to TPS79301
1. Description
The TPS793xx family of low-dropout (LDO) low-power linear voltage regulators features high power supply rejection ratio (PSRR), ultralow noise, fast start-up, and excellent line and load transient responses in NanoStar wafer chip scale and SOT23 packages. NanoStar packaging gives an ultrasmall footprint as well as an ultralow profile and package weight, making it ideal for portable applications such as handsets and PDAs.
- 53 -
Page 58
Each device in the family is stable, with a 2.2-µF ceramic capacitor on the output. The TPS793xx family uses an advanced, proprietary BiCMOS fabrication process to yield extremely low dropout voltages (e.g., 112 mV at 200mA, TPS79330). Each device achieves fast star-up times (approximately 50µs with a 0.001-µF capacitor) while consuming very low quiescent current (170 µA typical). Moreover, when the device is placed in standby mode, the supply current is reduced to less than 1 µA. The TPS79328 exhibits approximately 32 µVRMS of output voltage noise with a 0.1-µF bypass capacitor. Applications with analog components that are noise sensitive, such as portable RF electronics, benefit from the high PSRR and low-noise features as well as the fast response time.

3.5.4 Function introduction to G690L263T71
1. Description
The G690/G691 are microprocessor (µP) supervisory circuits used to monitor the power supplies in µP and digital systems. They provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V, +3.3V, +3.0V- powered circuits.
These circuits perform a single function: they assert a reset signal whenever the VCC supply voltage
- 54 -
Page 59
declines below a preset threshold, keeping it asserted for at least 140ms after VCC has risen above the reset threshold. Reset thresholds suitable for operation with a variety of supply voltages are available.
The G691L has an open-drain output stage, while the G690 have push-pull outputs. The G691L’s open-drain RESET output requires a pull-up resistor that can be connected to a volta ge higher than VCC. The G690L have an active-low RESET output, while the G690H has an active-high RESET output. The reset comparator is designed to ignore fast transients on VCC, and the outputs are guaranteed to be in the correct logic state for VCC down to 1V.
Low supply current makes the G690/G691 ideal for use in portable equipment. The G690/G691 are available in 3-pin SOT-23 packages.

3.5.5 Function introduction to TPS62200
1. Description
The TPS6220x devices are a family of high-efficiency synchronous step-down converters ideally suited for portable systems powered by 1-cell Li-Ion or 3-cell NiMH/NiCd batteries. The devices are also suitable to operate from a standard 3.3-V or 5-V voltage rail.
With an output voltage range of 6.0 V down to 0.7 V and up to 300 mA output current, the devices are
- 55 -
Page 60
ideal to power low voltage DSPs and processors used in PDAs, pocket PCs, and smart phones. Under nominal load current, the devices operate with a fixed switching frequency of typically 1 MHz. At light load currents, the part enters the power save mode operation; the switching frequency is reduced and the quiescent current is typically only 15 µA; therefore it achieves the highest efficiency over the entire load current range. The TPS6220x needs only three small external components. Together with the tiny SOT23 package, a minimum system solution size can be achieved. An advanced fast response voltage mode control scheme achieves superior line and load regulation with small ceramic input and output capacitors.

3.5.8 Function introduction to ISL6294IRZ
1. Description
The ISL6294 is a cost-effective, fully integrated high input voltage single-cell Li-ion battery charger. The charger uses a CC/CV charge profile required by Li-ion batteries. The charger accepts an input voltage up to 28V but is disabled when the input voltage exceeds the OVP threshold, typically 6.8V, to prevent excessive
- 59 -
Page 64
power dissipation. The 28V rating eliminates the overvoltage protection circuit required in a low input voltage charger.
The charge current and the end-of-charge (EOC) current are programmable with external resistors. When the battery voltage is lower than typically 2.55V, the charger preconditions the battery with typically 20% of the programmed charge current. When the charge current reduces to the programmable EOC current level during the CV charge phase, an EOC indication is provided by the CHG pin, which is an open-drain output. An internal thermal foldback function protects the charger from any thermal failure.
Two indication pins (PPR and CHG) allow simple interface to a microprocessor or LEDs. When no adapter is attached or when disabled, the charger draws less than 1µA leakage current from the battery.

Assembly and Disassembly Process
In order to get to know the structure of X19 (RU) more easily and directly, now we use pictures to present each key point of disassembly and assembly process before all users to prevent users from operating blindly and to damage elements, so we hope you can operate according to the instructions strictly.
Note: all operations must be with strict anti-static measures. Operators must wear anti-static gloves or wrist ring; electric screwdriver must be grounded effectively and articles, such as nippers must be removed static before using!
4.1 Disassembly process for the player
1. Remove the bottom casing by exerting strength in MIC hole (A in the figure) and pay
attention not to damage the aluminum alloy surface casing.
2. Use “+”-shaped screwdriver to remove screws A, B and C and then remove the stainless
board according to the arrow direction.
