1. General Section
1.1. Cautions/Warnings

1.1.1. Product Safety Notice

Parts marked with the symbol
in the schematic diagram have
critical characteristics.
Use ONLY replacement pares recommended by the manufacturer. It is
recommended that the unit be operated from a suitable DC supply or
batteries during initial check out procedures.

1.1.2. Leakage Current Check/Resistance Check

Before returning the unit to the customer, make sure you make
either (1) a leakage current check or (2) a line to insulated
resistance check.
If the leakage current exceeds 0.5 milliamps, or if the resistance
from chassis to either side of the power cord is less than 240 K
ohms, the unit is defective.
WARNING: DO NOT return the unit to the customer until the
problem or located and corrected.
1.2. Safe Warnings
1.2.1. Protection of Eyes from Laser Beam
To protect eyes from invisible laser beam during servicing
DO NOT LOOK AT THE LASER BEAM

Page 2

Daewoo DM-K40 Service Manual

1.2.2. Laser Caution

CAUTION
Adjusting the knobs, switches, and controls, etc. or taking actions
not specified herein may result in a harmful emission of laser
beams. This CD Changer must be adjusted and repaired only by
qualified service personnel.
Laser symbol:

THIS IS COMPACT DISC PLAYER IS CLASSIFIED AS A CLASS 1 LASER

PRODUCT.
THE LASS 1 LASER PRODUCT LABEL IS LOCATED ON THE REAR EXTERIOR.

1.3. Precautions
1.3.1. ESD Precautions in Repairing
1.3.1.1. Do not apply excessive pressure on the mechanical
parts (moving pares), including the Pickup Block, as
extremely high mechanical precision or required in these
parts.
1.3.1.2. When soldering the microprocessor and signal
processing ICs, use a ceramic soldering iron or a soldering
iron whose metal part is grounded since they are not
resistant to static electricity.
1.3.1.3. When removing the solder or soldering the laser shorting
lands for the Pickup Block, use a ceramic soldering iron or
a soldering iron whose metal part is grounded since the
Page 3

laser diode or not resistant to static electricity.

1.3.2. DVD Loading Unit Precautions when handling the Mechanism
Block
1.3.2.1. Do not loosen any screws in the Pickup Block.
1.3.2.2. Do not adjust any screws in the Mechanism Block except
for Tilt Adjust Screws, as they are adjusted precisely at
the factory.
1.3.2.3. Replacement of the Pickup Block is impossible. Always
replace the Traverse Assy when the Pickup Block needed
to be replaced. Do not touch the lens or lens holder of the
Pickup Block.
1.3.2.4. The Guide Rails of the Pickup Block are greased. Take
care when handing.
1.3.2.5. When you try to slide the Pickup Block, do not press or
pull it directly. Always turn the dive gears with your fingers.
1.3.2.6. Be sure that the anti-slipping rubber on the turntable or
clean. If there is dust or it is greasy, clean the part with the
liquid that contains 50% each of alcohol and water.
1.3.2.7. When removing the Mechanism P.C.B. Assy, you need to
short-circuit the laser diode shorting lands beforehand.
1.4. Software Upgrade
You can upgrade DVD Player using the software we provide as following step:
Creating a software upgrade CD
Use only a new CD-R/CD-RW(not an erased one).
Give the CD a name of your choice(e.g. version and unit name).
Burn the unpacked documents on the CD-R/CD-RW.
The root directory(uppermost level) of the software upgrade CD
Attention: If a failure should occur during the software upgrade (e.g. a mains failure), it
may happen that the units function and a restart of the upgrade function are no longer
possible. If this should be the case, you must replace the intergraded FLASH ICs with
preprogrammed ICs (see corresponding spare parts list).
Insert the upgrade CD (see corresponding spare parts list) and observe the hints on
the display and on the screen of the TV set.
Carry out an initialization of the set.
Displaying the Software Version Number
Press one after the other the STOP and EJECT buttons on the unit.
Press theOSD with the remote control.
Using the cursor buttons on the remote control, select the software version MICRO
Version or CUSTOMER VERSION .The respective software version number then is
displayed

3.2. Read Disc Trouble Service Flow Chart

Read disc problem in a DVD player is a very complicated issue that
may involve complex issues. This problem is not only relation to the
electronic circuit, but also very much relation to the operation
environment.
DVD loading unit is a very complicate part that contains big number of
ESD components, which require specific equipment, tools and
technique to repair; in general, service technician is not suggested to
disassemble the DVD loading unit. It is suggest proving the trouble
and replacing the complete DVD loading unit, instead of repairing the
DVD loading unit in local workshop.
It is suggested to prove the faulty of a DVD loading unit by
replacement by a good DVD loading unit.
Before checking the "NO Disc" Trouble, ensure excluding the
following possibilities:
The test disc is damage.
AC power supply voltage dropped below the minimum required
level.
DVD disc region code and color system is not matching to the
DVD player or system setting.
Moisture condensed inside the unit. (Power on the unit, without
disc loaded, for 1/2 to 2 hours).
