This manual is the latest at the time of print, and does not include the modification
which may be made after the printing, by the constant improvement of product.
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 10kΩ 2W
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 1500Ω 10W 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 MTK1379 maintenance
1. Under normal power supply conditions, the maintenance plan for MT1379 mono-chip is: first the reset
circuit resets the MT1379, after the crystal oscillator circuit gave the clock signal to MT1379, MT1379 will
start the initialization check for Flash、E
start initialization check for 7Audio DAC, MT1336 and motor Driver.
2. If the all the a.m. parts are good, then MT1379 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 MT1336 will drive the CD laser to send out CD light and read the
data, the data then will be amplified through MT1336 and sent to MT1379 for data processing, released by
MPEG and resolved into video data and audio data, then they will be returned to analog signals through
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 MT1379
to see if there is faulty soldering. If there are normal signals at A0~A15, check if the address data
signal of MT1379 and SDRAM is normal. If it is normal, then check the signal at A16~A19 of
MT1379; if there are also signals, then check the 8 video data wires; it there is no signal, then
check the corresponding pins of MT1397 to see if there is any short circuit, break or faulty
soldering.
2)If all the a.m. conditions are good, but there is still no video signal output, then the filter circuit after
MT1379 shall be checked.
4. System in normal operation, but the audio has no sound.
1)Check if all the signals of DATA, MCLK, BCLK, LRCK and reset required by the Audio DAC are
exist, if there is signal missing, then check the signal line between MT1379 and Audio DAC. If the
line is connected properly, but there is no signal, then check if there is any welding problem at the
corresponding pins of MT1379. If it is still OK, it is probably the problem on MT1379 itself.
2)All the required signals are exist, while there is no audio output. Then you need to check the lower
passing amplifying circuit and the MUTE circuit at the back of Audio DAC. Also check if there is
any power supply to the Audio DAC.
3)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 between servo and MPEG, possible problems may be:
1) T1336 and its surrounding circuits have problems.
2) Servo part of MT1379 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 MT1379 to DMSO、FMSO are missing, the reason may be the
problem of MT1379 or the communication between MT1379 and motor Driver.
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 MT1379 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 MT1336 if there is RF net picture output, if there isn’t, then it must be the problem of MT1336
and external surrounding circuits, it there is output, then it might the problem of MT1369 and its
surrounding circuits.
2) There is RF signal,but not in normal status,then check MT1336 and surrounding circuits.
3 )Everything is normal, but the disc cannot be read out, check MT1369 and its surrounding circuit

PROM、SDRAM, after everything is checked to be normal, it will
