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.

- 1 -

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.

- 2 -

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.

3. RFO=A+B+C+D.

4. Focus error signal=(A+C)-(B+D) Trace error signal=E-F.

2. Working principle

(1) Laser tube: loader DVD laser diode wave length is 650nm and that of CD laser diode is 790nm;

if wave length is between 370nm and 750nm is visible light, laser during the course of reading DVD disc

is visible light and that if IR light when reading CD disc.

(2) Principle of laser head pick-up signal: laser beam projects onto disc vertically. When focus of

laser beam projects into disc, laser beam will produce reflection and reach light detect device through

reflection loop and switch into electric signals through photo-epectric conversion. The reflection loop

produced in non-pit information area and pin information area on discs are different and reflect into

different areas of light detect device, the photo-elecric diode in different positions of light detect device

will produce different signals to process light detect device diode signals and then produce digital

signals.

(3) Focus and trace winding: when laser head is reading signals normally, information side should

be in the focus of laser beam. Because of disc error and some factors, such as high speed rotation nd

mechanical error, laser beam will deviate from information side unavoidably to produce phenomena of

deflection and de-focusing; focus and trace coil are added to adjust laser beam to make it focus in

information area correctly.

(4) RF signal formation: when reading disc normally, light detect device will have 160MV vague eye-

shape waveform that are superposed on A, B, C, D, through being superposed by adder inside light

detect device, output RF signals from RFO pin; frequency when reading DVD disc is far higher than that

when reading CD disc and output range is about 1.4V.

3.2.2 Servo circuit

(MT1389HD+FLASH (16M) +SDRAM (64M)), and its servo circuit is mainly composed of front end signal

processing, digital signal processing and digital servo processing, digital signal processing IC MT1389E

and drive circuit Am58888, in which Mt1389 is also the main part of decode circuit. Servo circuit block

Figure 3.2.2.1 Servo circuit block diagram

2. Working principle: after power on or close to proper position (on loader frame for normal DVD, as

for PDVD, on PCB at the lower part of door), loader laser head begins to reset; after laser head reaches

proper position, detect switch will give a signal to Mt1389, Mt1389 begins to output focus, main axis and

light emission signals, machine begins to rotate, laser head begins to identify disc information and

decide whether disc is CD or DVD according to disc information to facilitate to output level from IOA pin

to make disc switch circuit and laser head PD IC make the relevant control action. At the same time,

Mt1389 adjusts laser output power through laser power control circuit.

After loader reading disc information, A, B, C, D, E, F signals are formed through photo-electric

conversion and sent out to Mt1389 (DVD only has A, B, C, D signals), and then inputted from pin 2~11,

18, 19 of MT1389. After being amplified and processed by the pre-amplifier inside MT1389, now signals

are separated to two part s for processing inside Mt1389. One part, through addition inside Mt1389 and

amplifying and subtraction circuit, produces servo error signal, after being processed by digital servo

- 18 -

Signal circuit, corresponding servo control signals form to output FOO, TRO, DMO, FMO digital servo

Control signals from pin 42, pin 41, pin 37, pin 38 of Mt1389 respectively, and FOSO, TRSO, DMSO,

FMSO, through integration circuit composed by resistor capacitor, and send to servo driver circuit for

amplification to bring along focus winding, trace winding, main axis electric machine and feed electric

machine after drive amplification. Among these, focus and trace servo are used to correct objective

position accurately; feed servo is used to bring along laser head to make radial large-scale move which

belongs to the preliminary adjustment to laser head position; and main axis servo is used to control main

axis electric machine to make it read signals in means of constant linear velocity and bring along disc to

rotate. After processing of amplification by VGA voltage control amplifier and equalization frequency

compensation inside MT1389, another part of signals are changed into digital signals through internal

A/D converter. When loader is reading CD/VCD signals, these signals are conducted EFM demodulation

inside MT1389, and then outputted to latter stage for AV decoding after finishing CIRC (Cross-

Interleaved Reed-Solomon Code) error correction inside. When loader is reading DVD signals, these

signals are conducted ESM demodulation inside MT1389, and then sent to latter stage for decoding

after finishing RSPC error correction inside. Normal DVD player has a open/close circuit to control the in

and out of door to reach the purpose of coneying discs; PDVD adopts manual open means and whether

it is close to proper position can be checked by detect switch.

3. Explanation to servo terms

(1) FOO: when rotating, disc may probably move upwards or downwards slightly to make the focus

of laser emitted by laser head cannot justly fall on data pit of disc, so laser head is required to move

upwards or downwards to make focus aim at data pit justly. When laser head is moving upwards or

downwards, it means that pick-up is making focus acts.

(2) TRO: data information is saved in disc in form of tracks. When disc is rotating, trace deviation

will produce and now laser head is required to be adjusted. In this process, it is objective, but the entire

pick-up, that moves forwards or backwards, and the moving range is very small.

(3) FMO: similar to acts of trace, the acts of feed are larger than those of trace. Feed conducts a

large scale movement firstly, and then trace moves slightly in this range. Feed moves for a while, and

does not move for another while; but trace moves all the time. Feed is rough adjustment and trace is fine

and acts are obvious when power on and selecting tracks.

(4) DMO: it is the top that holds up disc. Its rotation speed decides that of disc. Its rotation is

generated by an individual DC electric machine, in which rotation speed of DVD is twice over that of CD.

Pin 20/21 of Mt1389 is laser power detect input pin, pin 21 is DVD laser power strong/weak detect

signal input pin, pin 23 is VCD laser power drive control output pin and pin 22 is DVD laser power drive

control output pin.

LDV33

When reading VCD discs, laser power becomes weak, voltage of MDI pin decreases, voltage of pin

23 of Mt1389 decrease to make voltage of pin 19 of Xs301 increase to reach the purpose of promoting

laser power. When laser power is too strong, voltage of MDII pin increases to make voltage of pin 23 of

Mt1389 increase to make voltage of pin 19 of Xs301 decrease to reach the purpose of reducing laser

power to form an auto power control circuit.

When reading DVD disc, pin 21 is detect signal input pin, pin 22 is drive control output pin and

working principle is the same with that when playing VCD disc.

2. Working principle: after loading disc into the machine, IOA end of ,Mt1389 is defaulted high level

to make Q305 saturated on and form loop with CD laser power control circuit on loader. At the same time,

IOA directly reaches loader PD IC for switch and disc begins to rotate. When servo processing system

identifies that disc in machine is not CD, IQA pin outputs low level to make Q305 cut off, Q303 is on and

forms loop with DVD laser power control circuit on loader to perform the action of reading DVD disc.

After disc tray opens, IOA still keeps the state before opening disc. If the machine cannot identify which

disc is in this machine, IQA pin will switch continuously until disc has been read or system judges that

there is no disc in.

Note: Q303, Q304 are MOS pipe

2. Function: disc is always in high speed rotation state when machine is reading discs, when it is

necessary to open door and change another disc, MT1389 stops giving positive phase drive signals to

main axis drive circuit, but disc is still rotating due to the function of inertia. If the action of opening door

is carried out at this moment, disc will be worn, so the machine must apply brake to main axis. Whether

disc has stopped rotating or whether it is rotating reversely, decode chip cannot judge, so a main axis

control circuit is added to make decode chip can effectively monitor whether disc has stopped rotating.

3. Working principle: MT1389 has a built-in comparator composed of operational amplifier, in which

OP is the in-phase input end, OP- is reverse input end, OPO is output end. When playing normally,

electric machine is rotating in positive direction, voltage of OP+ is higher than OP-, voltage of OPO is

more than 1.4V. When it is necessary ti open disc door, main brake signals stop, electric machine is

eternal magnet, so when rotating, inductive electromotive force produces on two ends, through R320,

R319 sampling, to give to decode chip to make OPO output voltage lower than 1.4V and transmit to

MT1389 ADIN input pin through R318; when ADIN is high level, main axis does not make any acts, when

inside doubling circuit.

(3) Power: decode chip adopts 2 groups of power supply: 3.3V and 1.8V, in which 1.8V is mainly

provided for internal logic control circuit, which is called core voltage by us.

After power on, reset circuit performs reset to Mt1389 built-in CPU (8032) and FLASH, decode chip

outputs reset signals at the same time and performs reset to other circuits. After system reset, read

signals are firstly sent to FLASH to read out information saved inside FLASH, machine displays

power0on picture, servo system begins to work and check whether door os closed to proper position and

whether detect switch is shut, if not, action of closing door is performed. After detect switch is shut,

machine begins to perform the preparations of disc reading and panel display.

Playback process: laser head picks up disc information from discs, through being processed by

servo system, and sends to decode circuit for decoding, and signals after being decoded are saved in

SDRAM. When machine required to replay signals, decode circuit calls out information inside SDRAM

for output.

Save user information: information set by users is saved inside EEPROM and will be saved inside

IC forever if users does not update or reset this information.

Audio, video output circuit: at present, Mt1389 integrates video D/A converter, Mt1389 integrates

audio D/A converter inside, and manufacturers may select according to their own demands, therefore

when in audio decode output, part is analog output and part is digital output. Please refer to circuit

diagram and audio circuit for details.

2. Working principle: after power on, voltage of Dv33 increases to 3.3V and main chip power supply

is normal. Now, Tc208 cannot change voltage of Dv33 suddenly, base electrode of Q201 has current in,

Q201 is saturated on, URST is low level. Dv33 charges Tc208 through emitter electrode of R219 and

- 25 -

Q201 to make voltage of cathode of Tc208 decreases gradually. When this voltage is below 0.7V, Q201

cuts off, URST changes into high level, and the process for URST from low to hgih is called low level

effective reset signals by us. After power off, voltage of Dv33 decreases, Tc208 and Dv33 voltage

decreases together, D201 performs surge discharge and clamping to TC208.

2. Working principle: MT1389 has built-in video D/A conversion circuit, video output has R/B/G,

Y/Pb/Pr, Y/Cb/Cr, CVBS, Y/C output mode, in which R/B/G, Y/Pb/Pr, Y/Cb/Cr, Y/C cannot output at the

same time and need software to switch. CVBS is a separate output mode, 4-channel video signals

outputted by MT1389, after video filtering and clamping, output to video terminal.

Shown in the figure 3.2.9.2, capacitor C287, C288 and inductor L227 compose a low-pass filter to

filter high frequency interference signals except for useful signals; dual diode D211 composes a

clamping circuit. It is known from features of diode that the most range of composite video signal CVBS

cannot be over 5.7 and cannot lower than -0.7 in minimum, thus high voltage signals from TV set can be

prevented from burning down the player.

2. Quieting circuit working principle:

When the player is working normally, shown in the figure 3.2.11.1, when chip is outputting analog

audio signals, it outputs s low level signal at the same time to

VMUTE to make Q211 on, voltage of

Q211B electrode is about 2.7V, voltage of Q211 collector electrode is about 3.3V, so Q212 is also on;

voltage of B electrode is about 0.7V, voltage of Q213 E electrode is close to zero, Q213 cuts off, MUTE-1

is negative voltage, which is added to base electrode of mute pipe of audio output end to make mute

pipe cut off and audio signals output after being amplified by 4558. When in mute, MT1389 has no audio

signals that output to operational amplifier, so audio output end of the player should have no audio

output; electronic elements in circuit and IC will produce some noise to transmit to audio output end of

the player, in order to filter these noise, decode chip outputs a high level signal to VMUTE to make Q211

cut off, so Q212 cuts off, +5V power transmits through E C electrode of Q213 to base electrode of switch

pipe Q205-Q210 and circuit is in mute.

When the machine is not playing discs, decode chip outputs a high level signal to VMUTE to make

circuit enter mute.

3. Power-off quieting working principle:

Shown in the figure 3.2.11.1, when the player is working normally,

D204 is on, +5V charges

capacitor TC235 through D204, now voltage of emitter electrode of Q214 is lower than voltage of base

electrode and Q214 cuts off. When power off, +5V disappears, Q214 base electrode changes to low

level, and its emitter base changes into high level because of discharge of TC235, now Q214 is on,

collector electrode of Q214 (AMUTE) outputs high level to add to the base electrode of switch pipe

Q205-Q210, switch is saturated, the noise produced in the course of power on and off is bypassed to

ground, and power-off quieting function is realised.

(1) Power grid filtering circuit: various electromagnetic radiation exits in surrounding, so it will

produce interference to inputted AC current. The function of power grid filtering circuit is to filter there

interferences to make those that enter bridge rectification circuit are comparatively pure 220V AC power.

(2) Bridge rectifying and filtering circuit: the function of this circuit is to switch city power into DC

power. Voltage after rectifying and filtering is 1.414 times of input power, so the DC voltage on two ends

of TC501 is equal to 300V.

(3) Absorption loop: power always works in on/off state, so very high peak voltage will produce in

the course of power on and off. In order to protect switch IC better, a peak absorption loop is added.

(4) Filtering circuit: the function is to produce a comparatively stable and small ripple DC voltage. In

filtering circuit, “ "-type filter is adopted most of the time. The features of capacitor filtering are that

when load resistance is high and current is small, filtering is obvious; as for inductor filtering, when load

resistence is small and current is large, filtering is obvious. To constitute capacitor into “ "-type filter,

better filtering effect may be achieved.

- 29 -

(5) Feedback loop: the time length of “on” and “off” in the same cycle inside switch module VEPR22

is decided by feedback loop. Feedback loop samples +3.3V output voltage; when output level is too high,

voltage after being sampled is on high side, through feedback loop, space occupation ratio of pin 3

signal of VEPR22 is changed, “on” time reduced and output voltage begins to decrease. When output

voltage is too low, voltage after being sampled is on low side, through feedback loop, space occupation

ratio of VEPR22 increases, output voltage increases. Through the function of feedback loop, power

board outputs stable voltage. LM431 used in this power is a 2.5V comparator. Compare sampling

voltage with this 2.5V voltage, when sampling voltage is more than 2.5V (output voltage is on high side),

LM431 is on, light emission diode in photoelectric coupler begins to emit light to make the other end of

photoelectric coupler begin to be on; light emission of light emission diode is stronger, the degree of “on”

is larger, the time of “on” of switch module VEPR22 decreases, output voltage begins to reduce. When

sampling voltage is lower than 2.5V (output voltage is on low side), LM431 cuts off, “on” time of VEPR22

increases and output voltage increases, thus, through he auto control function of feedback loop, power

board can output comparatively stable voltage.

MIC part working principle: when microphone is inserted into MIC left, DET signals change from low

level to high level to make mute circuit of decode part off. No matter disc reading is available, audio

signals may be outputted. If this signal has trouble, microphone will have no sound when playback stops.

After being filtering, signals inputted by microphone output to pin 5 of U601 and signals after discharge

output from pin 7 of U601, after second amplifying, outputted by pin one of U601 to decode board

directly for Karaoke signal processing and output together with audio signals to fulfil Karaoke function.

2. Working principle: panel components are divided into main panel and subordinate panel. Main

panel is mainly composed of VFD display screen, drive chip V6312A, remote controller IR receiver and

indicator light; subsidiary panel is composed of power button and power indicator light.

VFD screen is a vacuum fluorescence display screen and working principle is the same with that of

CRT, which depends on striking fluorescence powder. GRID1 GRID8 is segment control, equal to grid

electrode, speed up electronic emission, responsible for the display selection with the netlike range in

screen. SEG1 SEG9 is bit control, connected on single character with fluorescence powder on it, and it

will emit light and display when electronics strike it and responsible for the display of character.

The function of U401 (V6312A) is to process data signals sent from decode board to drive screen to

display the relevant state, and scan the panel buttons matrix at the same time, after processing button

information, send to CPU in the means of digital signals to control the player to make the relevant action.

Pin 2 of remote control IR receiver HS0038B3V is 5V power supply pin, pin 1 is grounded, pin 3 is

output pin; after the receiver processes button information of remote controller, it outputs from pin 3 to

send to decode board directly.

Section Four Waveform diagram

This section collects signal waveform diagram of audio, video and each unit circuit with the

purpose 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.

Section Five Function Introduction to IC

3.5.1 function introduction to MT1389HD

1. Description

MT1389HD is a cost-effective DVD system-on-chip (SOC) which incorporates advanced features like

MPEG-4 video decoder, high quality TV encoder and state-of-art de-interlace processing.

Based on MediaTek’s world-leading DVD player SOC architecture, the MT1389E is the 3rd generation of

the DVD player SOC. It integrates the MediaTek 2nd generation front-end analog RF amplifier and the

Servo/MPEG AV decoder.

To enrich the feature of DVD player, the MT1389 equips a simplified MPEG-4 advanced simple profile

(ASP) video decoder to fully support the DivX1 Home Theater profile. It makes the MT1389-based DVD

player be capable of playback MPEG-4 content which become more and more popular.

The progressive scan of the MT1389HD utilized advanced motion-adaptive de-interlace algorithm to

achieve the best movie/video playback. It also supports a 3:2 pull down algorithm to give the best film effect.

3.5.16 function introduction to LM1117

1. Description

The LM1117 series of adjustable and fixed voltage regulators are designed to provide 1A output current

and to operate down to 1V input-to-output differential. The dropout voltage of the device is guaranteed

maximum 1.3V at maximum output current, decreasing at lower load currents.

On-chip trimming adjusts the reference voltage to within 1% accuray. Current limit is also trimmed,

minimizing the stress under overload conditions on both the regulator and power source circuitry.

The BM1117 devices are pin compatible with other three-terminal SCSI regulators and are offered in the low

profile surface mount SOT -223 package and in the TO-252 (DPAK) plastic package.

2. Features

Three Terminal Adjustable or Fixed Voltages 1.5V, 1.8V, 2.5V, 2.85V, 3.3V and 5.0V

Output Current of 1A

Operates Down to 1V Dropout

Line Regulation: 0.2% Max.

Load Regulation: 0.4% Max.

SOT-223 and TO -252 package available

3.PIN DESCRIPTION

PIN No. Symbol I/O Description

1 GND/adjust I Ground (fixed)/adjust (adjustable)

2 Vout O Voltage output

3 Vin I Voltage input

Chapter Four

Disassembly and Assembly Process

DVD players manufactured in BBK are largely identical but with minor differences and are mainly

composed of loader components, control panel components, decode and servo board components,

power board components, power amplifier board components, MIC board components and AV board

components. In order to speed up the compilation of “Service Manual”, we shall not give repeat

explanation to model with minor differences in chapter four “Disassembly and Assembly Process” for the

later compiled service manuals. For disassembly and assembly process in this chapter, please refer to

chapter 4 of “DK1005S Service Manual” or “DK1020S Service” .

The pictures of this model are shown as follows:
