                 Chapter One About Maintenance



     1.1 Safety precautions
     1.1.1 Power supply
     When maintenance personnel are repairing DVD TV, he should pay special attention to the power
with 220V 800V 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 display screen
     1. Display screen is breakable article, so please protect carefully when carrying and prevent fingers
or hard objects striking the screen to damage structure of the screen.
     2. When cleaning screen, do not use organic chemicals. You should use cloth and use small
amount of special cleaning liquid in places difficult to clean.


                                                     -1-
     1.1.4 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.



     1.1.5 About placement position
     1. Never place TV 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 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.



     1.2.2 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.



     1.2.3 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.



    1.2.4 Element substitution method
     When some elements cannot be judged good or bad, substitution method may de adopted directly.



     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 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.



    1.2.7 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.
