Chapter One About Maintenance

1.1 Safety precautions

1.1.1 Power supply

When maintenance personnel are repairing DVD players, he should pay special attention to the

power board with 220V AC and 330V DC which will cause hurt and damage to persons!

1.1.2 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.

1.1.3 Precautions for laser head

1. Do not stare at laser head directly, for laser emission will occur when laser head is working, which

will Hurt your eyes!

2. Do not use wiping water or alcohol to clean laser head, and you may use cotton swab.

Page 7

1.1.4 About placement position

1. Never place DVD player in positions with high temperature and humidity.

2. Avoid placing near high magnetic fields, such as loudspeaker or magnet.

3. 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

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.

Page 8

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.

Section Two Unit Circuit Principle

3.2.1 Working mode introduction

1. External input: externally-inputted video signals input to U15 (TVP5146) for input source

selection and A/D conversion. TVP5146 converts NTSC, PAL video signals to digital component

video signals and transmit to DMN-8652 for MPEG encoding, signals after encoding are sent to

DVD recorder driver for disc recording storage, or sent to hard disc for storage, meanwhile convert

to analog video signals through the video decode and D/A converter inside DMN-8652 for output,

and analog video signals output through filtering, clamping and amplifying. Externally-inputted

audio signals firstly input to AV board (U15 MSP3415) for NICAM processing and sound source

selection and then input to U1 4052 for channel selection, audio signals after selection are sent to

A/D converter CS5340 of decode board, CS4360 converts analog signals to digital audio signals

and input to A IN jack of DMN-8652, after DMN-8652 encode processing, input to loader and hard

disc for storage. At the same time, digital audio signals output from A OUT jack of DMN-8652 to

send to DA converter CS4360, CS4360 converts digital audio signals to analog signals and analog

signals output after being amplified.

2. DV input: DV signals input to decode board through DV jack board, the cable transceiver

(TSB41AB1) of decode board decodes the inputted DV digital signals and sends the data after

being decoded to 1394 jack of DMN-8652 directly, DMN-8652 performs encoding processing to

signals and sends to DVD recorder driver or hard disc for recording storage after encoding,

meanwhile make signals after encoding output from DMN-8652 analog video output jack (VDENC)

and AVOUT analog audio output jack and users can watch programs at the same time when

recording.

3. DVD signal output: DMN-8652 communicates with DVD Recorder through ATAP jack, disc

information read out by DVD Recorder is sent to DMN-8652 for decoding through ATAP jack, the

data after decoding are sent to analog video output jack (VDENC) and digital audio output jack

AOUT for output. The working principle of hard disc playing is the same with that of disc playing.

- 42 -

Page 48

4. USB jack: DMN-8652 has a USB1.1 jack that supports two modes of low speed and high

speed transmission. USB data is sent to USB jack of decode board DMN-8652 through jack. The

working principle is the same with that of hard disc playing, and only the jack is different.

2. D/A conversion circuit (decode board part)

When the player is working, decode chip U1 DMN-8652 reverts the disc information sent from

loader to digital audio signal, and outputs audio data through the pin of decode chip AOUT module

to send to CS4360 for D/A conversion, analog 5.1CH audio signals output, through coupling

capacitor and filtering capacitor C243-C248 for filtering, audio signals are sent to socket CN4 and

then to AV for amplifying and output. The outputted signals have SUBWOOFER, CENTER,

REAR_R, REAR_L, A_R_OUT A_L_OUT and optical and coaxial signals (OPTECAL, APDIF_OUT)

of digital audio output.

Audio signals output through pin 11 of TUN1, and mono channel audio signals may also output

from pin 14. Now we do not use pin 14 to output mono channel audio signals. Audio signals TV_IF,

through C80 C81, are coupled to NICAM decode IC U6 (MSP3415) for NICAM decode, and at the

same time the audio input of SCART1 SCART2 also inputs to U6 for channel selection of audio

input. Audio signals after switching are outputted by pin 30/31 of U6. When machine is set in TV

signal input, BTSC_AINL and BTSC_AINR outputs audio signals of TV, and TV audio signals after

being decoded output from pin 30, 31 of U6 to send to UI.

of sound sources: front audio input (F_AUDIO), rear audio input (R_AUDIO), audio signals inputted

by NICAM decode IC (BTSC_AINR BTSC_AINL), sound source or FM sound source used by LOOP

function (this ground not used). Audio signals input from pin 1, 2, 4, 5, 12, 14, 15, 11 of U1, U1 has

two groups of 1-in-4 electric switch, after U1 selects the input sources, outputted by pin 3, 13 to

audio A/D conversion circuit. The output is controlled by the level of pin 9, 10 of U1.

by pin 13, 3 of U1 to CN2 and transmit to decode board CN6. The inputted audio signals are directly

inputted to audio A/D converter CS5340 (U18) for A/D conversion.

Analog audio signals input from pin 16, 12, digital audio signals AI_D0 after A/D conversion

input to DMN8652 directly for encoding and recording. DMN8652 outputs this audio signal at the

same time. Audio output circuit outputs audio signals.

IIC bus control circuit

IIC bus a kind of simple, dual-direction, two-wire system and synchronous series bus

developed by PHILIPS company. Only two wires (serial clock line and serial data line) needed that

information can be transmitted between elements connected on the bus. This bus is high-

performance serial bus with functions of ruling required by multiple host machine system and

synchronization of high/low speed device which is used widely.

2. IIC bus level switch principle

In this player, decode board IIC bus uses 3.3V level, while elements such as AV board tuner

need to use IIC of 5V level, so a level conversion circuit is added on circuit. This circuit utilizes the

on/off features of MOS tube, when main chip outputs 3.3V pulse, UGS is 0V, MOS pipe cuts off,

under the function of pull-up resistor, D electrode of MOS tube has 5V pulse that outputs to AV

board to realize level switch. When main chip is low level, UGS is 3.3V, MOS tube is on, and D

electrode of MOS pipe is low level.

3. Data transmission criterion of IIC bus

Data transmission once of IIC bus from host machine is called a frame, composed of start

signal, address code, several data byte, replay bit and stop signal. When communication starts up,

a start signal (when high level is on SCL line, a drop edge produces on SDA line), address code (8-

bit) of subordinate machine and read-write signal are sent automatically; when communication

stops, host machine sends a stop signal (when high level is on SCL line, a rise edge produces on

SDA line). During the course of data transmission, when high level is on SCL line, data on SDA line

must be confirmed steady; when data of a byte is transmitted, a relay signal must be sent by

receiver. Transmission speed of bus is 100kbps (standard) - 400kbps (high speed). When +5V

power supply is adopted, input level is ruled as VILmax=1.5V, VIHmin=3V; when wide power

voltage is adopted, level is ruled as VILmax=1.5VDD, VIHmin=3VDD. In this player elements

controlled by two levels of 5V and 3.3V are adopted, so a level conversion circuit is added in the

connecting end of AV board and IIC bus of decode board to increase the stability of system.

4. IIC bus defined by DMN8602 is used to control each function circuit in this player. To make

understanding easier, we suppose DMN8602 is host machine, other chips are subordinate machine,

host machine sends control information and receives state report information sent back from each

subordinate machine and sends new control information according to the report information to

function circuit required to control. Subordinate machine may carry out the control information sent

from host machine and report the state information of this machine to host machine to realize the

control function of I2C bus through dual-direction information exchange course. In which 24C16 is

state memorizer that mainly saves information set by user and required to store for the usage of

next time. Main functions of this player may be controlled by IIC bus (such as video A/D conversion,

audio D/A conversion, tuner channel selection, user information and NICAM decode).

3.2.10 DV jack circuit

In DV player and DVCAM player, a flat 4P or 6P port may be seen and this is often-called DV

digital jack. Sony names it i.LINK that accords with IEEE 1394 standard. The features are as

follows:

Transmit digital data directly, so there is no picture and audio deteriorate.

Only one cable is needed to make video, audio and control signal perform data multiplex

transmission.

With hot-plugging function, and data transmission among multiple devices is available.

Externally-connected DV signals input through DV jack board to DV jack chip TSB41AB1

through decode board socket J6 for processing.

TSB41AB1 is a DV jack IC responsible for conversing external DV signals to signals required

by main chip and inputting to main chip. The internal DV monitoring circuit can automatically detect

DV input. When system selects DV mode, DMN-8652 communicates with TSB41AB1; when DV

jack has signal input, signals inputted by DV input to pin 27-30 of TSB41AB1, after being processed

by TSB41AB1, and send to DMN-8652 doe encoding and decoding.

This player uses two IDE jacks connected with a “loader components” and a hard disc. Loader

components include servo circuit, laser head and mechanical part, with working principle the same

with that of other DVD player. We consider the hard disc as a whole in this player and the jack is

totally the same with loader. The pin introduction to IDE jack is shown in the following table:

Shown in the figure 3.2.12.2, it is a low level effective reset circuit, after power on, VDD power

charges C11 through R24, the voltage on two ends of capacitor cannot change suddenly, so Q1

base electrode is high level, Q1 is saturated on, RESET end outputs low level; the charge course of

capacitor makes the electric potential of Q1 base electrode decreases quickly, Q1 cuts off, RESET

3. Remote control circuit

The power supply of remote control circuit uses 5V_STB power to ensure the remote control

receiver can receive the instruction transmitted from remote controller in standby status. The

remote control instruction received by remote control receiver directly transmits to panel IC for

remote control decode.

In standby status, panel IC only receives the wake code transmitted from remote controller.

4. Standby working status

After power on, P_CTL_PSW control end is low level, now power board main power +12V, +5V,

+3.3V have no voltage output, 5V_STB and other supplementary winding power outputs normally

to provide reset circuit to reset U1 (pin 4 of U1) at the same time of power on, panel IC standby

module enters working status, in which Y2 and the clock circuit inside IC produce clock signal to

realize the time display and timing function in standby status, Y1 is externally connected clock of

D16316. In standby status, panel control IC and display screen have working power, so the display

screen of machine can normally display the time in standby status.

5. Working status after power on

When users are pressing POWER button on the panel or remote controller, UPD16312 enters

normal working status, P_CTL_PSW ens inputs high level, panel standby indicator light turns out,

the blue light of panel receives power and is on, main power output of power board is normal, each

circuit of the player begins working, machine displays power-on picture and enters working status.

After power on, audio circuit will produce noise in the course of power on, to avoid noise being

amplified outputted, panel IC (46PIN) outputs MUTE signal to mute circuit (working principle will be

introduced in mute circuit), after decode system works, it communicates with panel IC to fulfill

functions of panel display and remote control function operation.

3.2.13 AV circuit

2. Clock circuit: shown in the figure 3.2.13.2, clock circuit mainly provides a clock signal for

system, which can record year, month and date. Power supply means of External battery or

standby power is adopted, U2 is clock IC with working voltage between 2.0 and 5.5V, after machine

power off, battery Bt1 supplies power for U2 through D2, after the player power on or enters

standby status, 5V_STB supplies power for U2 through D1. D1 D2 makes a separation function in

the circuit.

3. SCART output mode control circuit

(1) CVBS/RGB output control circuit: when the machine is in power-on status, SCART terminal

is required to output RGB signal, we switch the output mode if machine in RGB state, shown in the

+5V power is 0V, Q29 cuts off, Q27 is controlled by VI_FSS end level of SCART input terminal, so

SC1_CVBS_RGB_SEL end is controlled by VI_FSS end, now output mode is decided by external

input source.

(2) Screen display ratio control circuit

When the machine is playing discs with different ratio pictures, if SCART terminal output is

needed, we set “screen ratio setup” item in machine setup page according to requirements, shown

in the figure 3.2.13.4, E5_GPIOX2 end of decode chip outputs level to make Q17, Q20 on,

AV_CONTROL end outputs the voltage required by screen ratio switch to TV set. When machine

enters standby status (machine enters LOOP working mode), AV_CONTROL ens is controlled by

pin 8 of SCART input terminal.

When the player is in DVD playback status or external input status, LOOP_DECODER_C end

is low level, CVBS/RGB switch circuit and screen display ratio control circuit are both controlled by

the control signals outputted by decode. Audio/video signals input to U8 and output from pin 14, 15,

4 of U8, audio signals are directly sent to SCART output terminal for output, video signals are

amplified through the amplified circuit composed of Q22 and then sent to SCART output terminal

for output. There is one group of input port in output terminals. Suppose output terminal is

connected with TV set, audio/video signals sent from TV set input from input port to NICAM decode

IC for selection, and input to main board for record usage. Video signals select through U10,

Q34/Q35 amplifies and inputs to main board for record usage. Audio/video signals sent from tuner

output through U9 to the output port of SCART input terminal to connect decoder or other re record

devices. Component video switches through U7 and we have introduced in video output part.

Remark: this player does not use DECODER function; to be easy to understand, we define

SCART (SC2) is input terminal, and SCART (SC1) is output terminal.

(2) LOOP working mode signal flow chart and working principle

When the player is in standby status, the machine enters LOOP working mode (only when

SCART input and output are inserted at the same time, there is LOOP working mode function),

LOOP_DECODER_C end is high level; pin 14, 15 of U8 output the audio/video signals inputted by

SCART input terminal to make signals of input terminal connect to SCART output terminal through

U8 for output. There is one group of input port in output terminal. When output ens is connected

with TV set, audio/video signals sent from TV set input from the input port, after selection through

U9, output to the output port of “SCART input terminal” for output. The component video signals

inputted by SCART input terminal output to the amplified circuit composed of Q13 Q14 Q15 through

U7 for output. When LOOP is working, CVBS/RGB output control circuit and screen display ratio

control circuit do not work and are totally controlled by input source.

Remark: LOOP function is a switch function, in this period, the machine has no contact with

external signal, but is only used as a switch port. To be easy to understand, we define Sc1 as

output terminal, and Sc2 as input terminal (different from principle diagram, only for reference).

Shown in the figure 3.2.14.2, microphone detect is fulfilled through judging the level change of

microphone socket MIC_DET pin; when microphone is inserted, MIC_DET +12V voltage suddenly

decreases to 0V, C13 C14 in the circuit discharge through Q3 to make Q3 continue on, MIC_DET

end keeps outputting high level to MIC signal in mute. For the electric charge of C13 C14

discharges quickly, after a period, MIC_DET end outputs negative voltage and MIC signal may

output normally.

The delayed time may be changed through changing the RC constant of C14 C13 R17 R19.

2. Working principle: after city power is inputted, through protection circuit and power grid

filtering circuit, it directly enters the rectification circuit composed of D9 D12, in which protection

circuit has over-voltage, over-current and temperature protection circuit. After being rectified, city

power changes to DC current (the effective value is 1.4 times of city power, that is 300V) and is

rectified by CE5. 300V power is divided into two ways: one way, through R6 voltage drop, is

supplied to the start pin of switch module (IC1_6), the other way, through the 24 winding of

transformer, arrives at the power pin of switch module (IC1_1) to make transformer perform the

storage and discharge of energy through the internal switch pipe. When discharging energy,

reverse peak voltage will produce, to prevent damaging the MOS pipe in switch module, the

absorption loop protects MOS pipe. 5-6 winding is sampling winding, when the primary winding of

transformer is discharging energy, the induction current forms between secondary winding and

sampling winding, and induction voltage forms on the two ends of each secondary winding, after

being rectified through secondary rectification diode, provides the required DC power for each

circuit of the player. For power wave is large, to provide stable DC output, one winding of output

end, after rectification and filtering (+5V or +3.3V generally), performs sampling, which is fulfilled by

IC3 and the sampling circuit composed of the peripheral); when output voltage is on high side, IC3A

K is on to make the light emission diode inside IC2 emit light to control the photo triode inside IC2,

CE is on to change the space occupation ratio of switch pipe control end to make the output voltage

become low, or else output voltage is on high side.

3. Working principle for standby switching to power on

Power-on standby: 5V_STB is supplied to panel IC13616 to make panel circuit begin working,

display screen displays time, P_CTL pin of panel IC outputs low level to V_CRL end output low

level, power of +3.3V +12V +5V cannot output (other power is normally supplied during this period),

and machine enters standby status. After panel or remote controller inputs power-on instruction,

P_CTL pin of UPD16316 outputs high level to make B+12V arrive at the switch control circuit of

+3.3V, +12V, +5V through C-E electrode of Q9. Q2/Q7/IC4 is on, +3.3V +12V +5V output is normal,

and the player enters working status.

4. Working principle

Shown in the figure 3.2.15.2,

B+12V voltage after being rectified by D2, through being filtered

by the filter composed of L2/CE3/CE4, inputs to pin 1 of power board IC4, IC4 is a +12V voltage

stabilizing IC with on/off control function, when machine is in standby, state is P_CTL which is low

level, Q6/Q9 cuts off, V_VRL end outputs low level, when control end of IC4 is low level, pin 2 of Ic4

has no voltage output. When machine switches from standby to power on, P_CTL outputs high

level, Q6/Q9 is saturated on, V_VRL end outputs 12V level,IC4 is on, pin 2 of Ic4 outputs +12V

voltage and machine enters working state.

3.3.1 Servicing cases

Example 1 Description: power not on

Symptom: after connecting to power, power indicator light is not on, panel has no screen

display, and panel buttons have no function.

Analysis and troubleshooting: according to trouble symptom, we can judge that trouble lies in

power part. Firstly observe fuse, and it is bot burnt down; use DC level of multimeter to test voltage

on two ends of Ce5 and it is normal, which should be 300V in normal conditions, so we preliminarily

doubt that power switch IC does not work normally, shown in the figure 3.3.1.1, test voltage of each

pin of Ic1 in turn and find that pin 3 is 0V, pin 3 is start pin and it should be 22V, power off the

machine, use multimeter the resistance of R6 and it is normal, then test and find that resistance to

ground of pin 3 of Ic1 is 0 ohm, adopt disconnection method to disconnect CE11 D17, and

resistance to ground of pin 3 of Ic1 is still 0 ohm, so we doubt that IC1 FSDM07652R has trouble,

after changing IC with the same specification trouble is removed.

Figure 3.3.1.1 Power circuit diagram

Page 72

Example 2 Description: machine failure after power on

Symptom: after connecting with power, power indicator light is on, picture of the player has

output, but after pressing POWER button, HELLO displays all the time, panel buttons have no

function.

Analysis and troubleshooting: this kind of troule may lie in many places: loader, decode board,

AV board, I2C bus and abnormal voltage. “Replace” method is often adopted to repair this kind of

trouble machine. Firstly judge which semi-finished components caused this trouble, then repair the

defective semi-finished products. Firstly use multimeter to test loader and hard disk power supply

5V, 12V. When testing 12V voltage, it is 0V. +12V voltage is mainly supplied for small fan, loader

and hard disk. Under the condition of multiple channel power supply, adopt disconnetion method to

decide trouble range. After disconnecting power supply of loader, test power board +12V power

supply voltage and it resumes normal, which means the trouble of loader causes that there is no

12V power supply. After changing loader, trouble is removed.

Example Description: no sound

Symptom: DVD playing, external signal switch and TV signal receiving have no sound.

Analysis and troubleshooting: according to trouble symptom, we can judge that trouble lies in

audio output circuit. Firstly use multimeter to test power supply of AV board audio amplifying circuit

and +\-12V voltage is normal, test input pin of AV board audio amplifying circuit U3 and there is

audio signal input, use oscillograph to test C33, C37 of AV board and there is audio signal output,

which means that front stage circuit is normal, so we doubt that mute circuit has trouble. Use

multimeter to test mute circuit AMUET and it is high level, which means that mute circuit has started

up and machine enters mute state. Use multimeter to test base electrode of Q6 and find that base

electrode voltage of this triode is 4.5V, test base electrode of Q8 and find that this pin is high level,

this pin voltage is sent out from panel IC UPD16316, so we doubt UPD16316 has trouble, after

changing it, trouble is removed.

Example 4 Description: machine failure after power on

Symptom: after connecting to power, power indicator light is on, picture of the player has no

output, and panel has no screen display, panel buttons have no function.

Analysis and troubleshooting: adopting troubleshooting method of example 2 we judge that the

reason that leads to machine failure is the trouble of main panel, which shows in the following

aspects: clock is incorrect or there is no clock, reset circuit cannot work normally, main panel U1

(UPD16316) cannot work normally. Use multimeter to test each pin of U1 (UPD16316) and the

voltage and reset are normal, use oscillograph to test 5MHZ crystal oscillator and there is no

Example 5 Description: clock cannot be saved

Symptom: after power off each time, panel screen does not display the local time and system

time is disordered.

Analysis and troubleshooting: this player has RTC function, only local time has been set, when

power on again after power off each time, the local time will be kept unchanged. If clock is not

accurate, firstly check AV board RTC circuit. Shown in the figure 3.3.1.2, firstly test whether power

supply of U2 is normal, if power supply is normal, then use oscillograph to test X1 32.567KHZ

crystal oscillator and there should be oscillation waveform when in normal conditions, but in fact

there is no waveform now. After changing the crystal oscillator with the same specification, trouble

is removed.

Figure 3.3.1.2 Clock circuit diagram

Example 6 Description: machine failure when receiving TV signal

Symptom: machine failure each time when receiving TV signal, that is, panel buttons and

remote controller have no function, and other functions are normal.

Analysis and troubleshooting: according to trouble symptom, this trouble lies in AV board tuner

circuit. Firstly use multimeter to test power supply of tuner and I2C bus voltage, which should be 5V

for tuner power supply and 5V for IIC bus, but in fact IIC voltage tested is 5V, power supply of tuner

is 0Vnormal, after analysing through schematic diagram, tuner power supply loop, after power

board +5V being filtered by FB1 inductor, is provided for tuner, test power board +5V voltage and it

is normal, observe FB1 inductor carefully and it has been broken, after changing elements with the

same specification, trouble is removed. (Tuner cannot work, so machine failure when receiving.)

Example 7 Description: cannot search TV signal

Symptom: picture has serious white dots when receiving but there is no image.

Analysis and troubleshooting: machine failure when receiving TV signals is mainly caused by

AV board tuner circuit, use multimeter to test its power supply and I2C bus voltage, power supply

5V and IIC bus 5V are both normal, in the course of searching, pin 2 BT of tuner has high and low

voltage variation, which means that tuner works normally,, we pay attention to check the peripheral,

use multimeter to test the resistance of R16 and it is infinite, which is 0 ohm in fact, after changing

resistor with the same specification, trouble is removed.

Example 8 Description: picture of external input had mosaic

Symptom: when switching to external signal input, TV picture has interference, there is no

picture but there is sound.

Analysis and troubleshooting: according to trouble symptom, we can decide that trouble

appears in external input video processing circuit, the flow of external input signal is that external

video signals input to AV board, after A/D conversion by U15, digital video signals after U15

conversion input to decode chip in the means of parallel data. Firstly we test each power supply and

reset circuit of decode board U15 TVP5146 and the result is normal, then use oscillograph to test

clock signal of pin 74, 75 and find that clock is 14.31818MHZ and waveform is normal. So we doubt

that U15 has trouble, after changing U15, trouble is removed.

Example 9 Description: no MIC

Symptom: no sound after inserting microphone, sound of DVD playing, TV signal receiving and

external switch is normal.

Analysis and troubleshooting: according to this symptom, we can roughly judge that trouble

appears in Karaoke processing circuit. Firstly use oscillograph to test OK signal input pin of AV

board and find that there is no OK signal input, so we decide that trouble lies in MIC board. Use

signal generator to act as signal source, the output part is connected to MIC socket of MIC board,

use oscillograph to detect waveform from front stage to rear stage. Use oscillograph to test pin3 of

OK signal U1 4558 and there is input signal, then test pin 1 of U1 and find that there is no signal

output, which means that 4558 does not work normally, test the power supply voltage -12V, +12V

and it is normal, check the peripheral elements and they are normal, so we doubt that 4558 has

trouble, after changing U1, trouble is removed (if there is no signal generator, microphone can be

used to replace.).

Page 75

Example 10 Description: no image when receiving TV signals

Symptom: when playing DVD, picture, sound and external sound are all normal, only when

switching TV set, there is no image but sound is normal.

Analysis and troubleshooting: working principle of the tuner used in this machine has some

differences form that of the tuner used in TV set. Audio and video of the tuner used in this player

have separate output, seen from the schematic diagram, pin 12 of high frequency tuner outputs

video signals, which are coupled through C29 capacitor to Q31, Q33 for amplifying to send to pin

22 of AV board CN2 socket and output to decode board. Firstly use oscillograph to test pin 12 of

tuner and there is video signal output, then test emitter electrode of Q33 and there is also video

signal output, when testing 22 pin of decode board CN6 and there is no waveform output. Use

multimeter to test the resistance between pin 22 of AV board CN2 and pin 22 of decode board CN6

and it is infinite, which should be zero in normal conditions. After changing 26P flat cable, trouble us

removed.

Example11 Description: no sound when watching TV program

Symptom: DVD playing, sound and image of external signals are normal, and there is no sound

only when in TV signals input.

Analysis and troubleshooting: outputted by pin 14 of AV board high frequency tuner, TV signals

are sent to AV board U6 for NICAM processing, then outputted to U1 through pin 30, 31 of U6 after

NICAM processing, then sent to decode board for audio processing after gating. Firstly check

whether audio system is normal, use oscillograph to test pin 14 of AV board tuner and audio output

is normal, check U6 output pin and there is no waveform output, check pin 2 of U6 and there is

audio signal input, which means that this U6 does not work normally. Firstly check power supply

and reset of U6 and they are both normal, so we doubt that clock of U6 is abnormal, use

oscillograph to test X2 crystal oscillator and find that there is no oscillation waveform, so we doubt

that crystal oscillator has trouble, after changing 18.432MHZ crystal oscillator, trouble is removed.

Example12 Description: external input has no sound

Symptom: sound and picture of DVD playing are normal, when switching external signal, there

is picture but on sound.

Analysis and troubleshooting: this kind of trouble mainly appears in externally-inputted audio

signal processing channel. When in troubleshooting, start from rear stage circuit of U1 of AV board.

Machine is switched to external AV state. Use oscillograph to test pin 3 and pin 13 of AV board U1

and there is audio signal output, so we judge that external input circuit of AV board is normal, test

pin 10, 12 of decode board U18 (CS5340) and there is also audio signal input, so we judge that AV

- 70 -

Page 76

Board and the line from AV board to decode board U18 are normal, test pin 4 of U18 and find that

there is no digital signal output, test each pin voltage of U18 (CS5340) and they are all normal,

each clock signal is normal, so we doubt that CS5340 has trouble, after changing CS5340, trouble

is removed.

to help servicing personnel to judge where trouble lies in accurately and quickly to improve servicing

skills. For the difference of oscillograph's type, model and tuner, a certain difference may exist, so the

servicing personnel are expected to pay more attention to check in daily operation.
