1. SAFETY PRECAUTIONS
1. The design of this product contains special hardware, many
circuits and components especially for safety purposes. For
continued protection, no changes should be made to the
original design unless authorized in writing by the
manufacturer. Replacement parts must be identical to those
used in the original circuits. Service should be performed by
qualified personnel only.
2. Alterations of the design or circuitry of the products should
not be made. Any design alterations or additions will void the
manufacturer’s warranty and will further relieve the
manufacturer of responsibility for personal injury or property
damage resulting therefrom.
3. Many electrical and mechanical parts in the products have
special safety-related characteristics. These characteristics
are often not evident from visual inspection nor can the
protection afforded by them necessarily be obtained by using
replacement components rated for higher voltage, wattage,
etc. Replacement parts which have these special safety
characteristics are identified in the parts list of Service
manual. Electrical components having such features are
identified by shading on the schematics and by ( ！) on
the parts list in Service manual. The use of a substitute
replacement which does not have the same safety
characteristics as the recommended replacement part
shown in the parts list of Service manual may cause shock,
fire, or other hazards
4. Don’t short between the LIVE side ground and
ISOLATED (NEUTRAL) side ground or EARTH side
ground when repairing. Some model’s power circuit is
partly different in the GND. The difference of the GND is
shown by the LIVE: ( ) side GND, ISOLATED
(NEUTRAL): ( ) side GND and EARTH: ( ) side GND.
Don’t short between the LIVE side GND and ISOLATED
(NEUTRAL) side GND or EARTH side GND and never
measure with a measuring apparatus (oscilloscope etc.) the
LIVE side GND and ISOLATED (NEUTRAL) side GND or
EARTH side GND at the same time. If above note will not be
kept, a fuse or any parts will be broken.
5. If any repair has been made to the chassis, it is
recommended that the B1 setting should be checked or
adjusted (See ADJUSTMENT OF B1 POWER SUPPLY).
6. The high voltage applied to the picture tube must conform to
that specified in Service manual. Excessive high voltage can
cause an increase in X-Ray emission, arcing and possible
component damage, therefore operation under excessive
high voltage conditions should be kept to a minimum, or
should be prevented. If severe arcing occurs, remove the AC
power immediately and determine the cause by visual
inspection (incorrect installation, cracked or melted high
voltage harness, poor soldering, etc.). To maintain the proper
minimum level of soft X-Ray emission, components in the
high voltage circuitry including the picture tube must be the
exact replacements or alternatives approved by the
manufacturer of the complete product.
7. Do not check high voltage by drawing an arc. Use a high
voltage meter or a high voltage probe with a VTVM.
Discharge the picture tube before attempting meter
connection, by connecting a clip lead to the ground frame
and connecting the other end of the lead through a 10kΩ2W
resistor to the anode button.
8. When service is required, observe the original lead dress.
Extra precaution should be given to assure correct lead
dress in the high voltage circuit area. Where a short circuit
has occurred, those components that indicate evidence of
overheating should be replaced. Always use the
manufacturer’s replacement components.
9. Isolation Check
(Safety for Electrical Shock Hazard)
After re-assembling the product, always perform an isolation
check on the exposed metal parts of the cabinet (antenna
terminals, video/audio input and output terminals, Control
knobs, metal cabinet, screw heads, earphone jack, control
shafts, etc.) to be sure the product is safe to operate without
danger of electrical shock.
10. The surface of the TV screen is coated with a thin film which
can easily be damaged. Be very careful with it when handle
the TV. Should the TV screen become soiled, wipe it with a
soft dry cloth. Never rub it forcefully. Never use any cleaner
or detergent on it.
(1) Dielectric Strength Test
The isolation between the AC primary circuit and all metal
parts exposed to the user, particularly any exposed metal
part having a return path to the chassis should withstand a
voltage of 3000V AC (r.m.s.) for a period of one second.
(…Withstand a voltage of 1100V AC (r.m.s.) to an appliance
rated up to 120V, and 3000V AC (r.m.s.) to an appliance
rated 200V or more, for a period of one second.)
This method of test requires test equipment not generally
found in the service trade.
(2) Leakage Current Check
Plug the AC line cord directly into the AC outlet (do not use
line isolation transformers during this check). Using a
“Leakage Current Tester”, measure the leakage current from
each exposed metal part of the cabinet, particularly any
exposed metal part having a return path to the chassis, to a
known good earth ground (water pipe, etc.). Any leakage
current must not exceed 0.5mA AC (r.m.s.).
However, in tropical area, this must not exceed 0.2mA AC
(r.m.s.).
●Alternate Check Method
Plug the AC line cord directly into the AC outlet ( do not use
a line isolation transformer during this check.). Use an AC
voltmeter having 1000 ohms per volt or more sensitivity in
the following manner. Connect a 1500Ω10W resistor
paralleled by a 0.15μF AC-type capacitor between an
exposed metal part and a known good earth ground (water
pipe, etc.). Measure the AC voltage across the resistor with
the AC voltmeter. Move the resistor connection to each
exposed metal part, particularly any exposed metal part
having a return path to the chassis, and measure the AC
voltage across the resistor. Now, reverse the plug in the AC
outlet and repeat each measurement. Any voltage measured
must not exceed 0.75V AC (r.m.s.). This corresponds to
0.5mA AC (r.m.s.).
However, in tropical area, this must not exceed 0.3V AC
(r.m.s.).
This corresponds to 0.2mA AC (r.m.s.)

9. DVD Part: Introduction of MTK1389D maintenance
NOTE: MTK1389D is a type of LSIC for DVD decode .MTK1389D IC consists of
RF,SERVO,DSP,DECODE,VIDEO DAC and AUDIO DAC.
1. Under normal power supply conditions, the maintenance plan for MT1389D mono-chip is: first the reset
circuit resets the MT1389D, after the crystal oscillator circuit gave the clock signal to MT1389D, MT1389D will
start the initialization check for Flash、E2PROM、SDRAM, after everything is checked to be normal, it will start
initialization check for built-in Audio DAC, servo and motor Driver IC .
2. If the all the a.m. parts are good, then MT1389D will send signal to motor Driver to drive the servo
system，pick up then to generate DVD light for collection, tracing the main shaft to check if there is any disc, and
confirm if it is CD format or DVD format disc. If the disc is in DVD format, the system will read the data from the
disc directly; if it is in CD format built-in servo will drive the CD laser to send out CD light and read the data, the
data then will be amplified through built-in RF amplifier and sent to MT1389D decode part for data processing,
released by MPEG and resolved into video data and audio data, then they will be returned to analog signals
through built-in VIDEO DAC、AUDIO DAC.
Decoder section
3. There is power supply, clock and reset, but the system does not work.
1）Check if all the address wires required for FLASH are exist, and if they are in normal status,
especially check if the A0~A15 of FLASH have normal signals, if there aren’t, then inspect MT1389D to see if
there is faulty soldering. If there are normal signals at A0~A15, check if the address data signal of MT1389D
and SDRAM is normal. If it is normal, then check the signal at A16~A19 of MT1389D; if there are also signals,
then check the video output wires and AV filter circuit; if there is no signal, then check the corresponding pins
of MT1389D to see if there is any short circuit, break or faulty soldering.
4. System in normal operation, but the audio has no sound.
1）Because the AUDIO DAC is built in MTK1389D IC.you need to check the lower passing amplifying
circuit and the MUTE circuit at the back of the LPF circuit. Also check if there is any power supply to the LPF
circuit.
2）Check if the power supply voltage required for playing is at normal level.
Servo Section
5. After the LOGO of the machine shows normally, there is no OSD display. This problem mainly is caused
by the abnormality built-in RF and servo, possible problems may be:
1）Built in RF and its surrounding circuits have problems.
2) Servo part of MT1389D has problems.
6. OSD display is normal，while there is no action of servo part（feeding motor does not work, main shaft does
no turn, possible fault status are:
1) The corresponding signals giving by MT1389D to DMSO、FMSO are missing, the reason may be the
problem of MT1389D or the communication between MT1389D and motor Driver IC SA5668.
2) Not output from Motor Driver, the reason may be the problem on motor Driver or its corresponding
circuit.
7. Servo part in good status, while there is no pick up action（no light, no focus）
1）No light, check the power supply（power supply for pick up）, or the light producing driving circuit to see
if they are in normal status.
2）No focus, check MT1389D to see if there is signal output from FOSO、TRSO.
Secondly, check motor driver to see if there is F+、F-、T+、T-signal output.
Thirdly, check the external corresponding circuit of the motor driver to see if there is any problem.
8. All the servo part has action, while it cannot read out the disc
1）Check MT1389D if there is RF net picture output, if there isn’t, then it must be the problem of
MT1389D and external surrounding circuits, it there is output, then it might the problem of MT1389D
and its surrounding circuits.
2）There is RF signal，but not in normal status，then check MT1389D and surrounding circuits.
3 ）Everything is normal, but the disc cannot be read out, check MT1389D and its surrounding circuit
