2.1 Safety Instructions
2.1.1 General Safety
Safety regulations require that during a repair:
• Connect the unit to the mains via an isolation transformer.
• Replace safety components, indicated by the symbol ,
only by components identical to the original ones. Any
other component substitution (other than original type) may
increase risk of fire or electrical shock hazard.
Safety regulations require that after a repair, you must return
the unit in its original condition. Pay, in particular, attention to
the following points:
• Route the wires/cables correctly, and fix them with the
mounted cable clamps.
• Check the insulation of the mains lead for external
damage.
• Check the electrical DC resistance between the mains plug
and the secondary side:
1. Unplug the mains cord, and connect a wire between
the two pins of the mains plug.
2. Set the mains switch to the 'on' position (keep the
mains cord unplugged!).
3. Measure the resistance value between the mains plug
and the front panel, controls, and chassis bottom.
4. Repair or correct unit when the resistance
measurement is less than 1 MΩ.
5. Verify this, before you return the unit to the customer/
user (ref. UL-standard no. 1492).
6. Switch the unit ‘off’, and remove the wire between the
two pins of the mains plug.
2.1.2 Laser Safety
This unit employs a laser. Only qualified service personnel may
remove the cover, or attempt to service this device (due to
possible eye injury).
2.2 Warnings
2.2.1 General
• All ICs and many other semiconductors are susceptible to
electrostatic discharges (ESD, "). Careless handling
during repair can reduce life drastically. Make sure that,
during repair, you are at the same potential as the mass of
the set by a wristband with resistance. Keep components
and tools at this same potential. Available ESD protection
equipment:
– Complete kit ESD3 (small tablemat, wristband,
connection box, extension cable and earth cable) 4822
310 10671.
– Wristband tester 4822 344 13999.
• Be careful during measurements in the live voltage section.
The primary side of the power supply (pos. 1005), including
the heatsink, carries live mains voltage when you connect
the player to the mains (even when the player is 'off'!). It is
possible to touch copper tracks and/or components in this
unshielded primary area, when you service the player.
Service personnel must take precautions to prevent
touching this area or components in this area. A 'lightning
stroke' and a stripe-marked printing on the printed wiring
board, indicate the primary side of the power supply.
• Never replace modules, or components, while the unit is
‘on’.
2.2.2 Laser
• The use of optical instruments with this product, will
increase eye hazard.
• Only qualified service personnel may remove the cover or
attempt to service this device, due to possible eye injury.
• Repair handling should take place as much as possible
with a disc loaded inside the player.
• Text below is placed inside the unit, on the laser cover
shield:

4. Press button on the remote control for 5 times.
5. The change should effect immediately with information
indicated on TV screen.
5.1.3 Software Upgrade via Download Disc
5.1.5 ComPair
There is no ComPair available for DVD580M player
5.2 Trouble Shooting
In this paragraph some troubleshooting tips are given to
diagnos the DVD580M player. For detailed diagnostics, check
the faulting tree since no built-in diagnostic software is
available in the player.
5.2.1 DVD Engine
The DVD engine is a non-repairable component. Hence, it is
necessary to determine if any fault condition of the player is
caused by the DVD engine before replacing it.
The engine is a stand-alone system, an integrated unit of Slot
loader and servo board, which does not need to be connected
to the decoder board to perform it basic operations. Once a
stable voltage is supplied to the engine,some mechanical
movement will be observed. Hence, to determine whether the
engine is faulty, remove the 40 pins flex cable and observe the
mechanical movement. If no mechanical movement is
observed, the engine should be faulty and it should be
reconfirmed with a working engine.
The Slot Loader has an optical unit consisting of two lasers,
one for CD with a wavelength of 780 nm, and one for, DVD with
a wavelength of 650 nm. If any one type of disc (DVD or VCD /
CD) cannot be identified by the player, it can be sure that the
fault is due to the engine.
The application software can be flashed into the DVD player by
means
of a CD-ROM disc. The CD-ROM disc has to be made with a
CD writer.
Note: Ensure the filename used for making the CDR must be
identical to the application software file name as display in the
player.
Application Software
1. Insert the DOWNLOAD DISC into the player.
2. The upgrading operation will start automatically.
3. Once the DOWNLOAD DISC is recognized, the player will
display the filename on the TV screen.
4. The word will flash on the TV screen indicates the
progress.
5. Once when the upgrading is completed, the word will
display momentary on the TV screen.
6. The TV screen will become BLUE and the player will goes
into standby mode.
5.1.4 Verify Setting
To check that the setting has change successfully.
1. Press button on the front of the player.
2. Press button on the remote control while display shown
EJECT.
3. Two lines text will appear on the TV screen. That is how it
looks like.
– TD580A.00B
– TDDVD580V02-ES
4. In the text, the following numbers refer to:
– TD580A.00B ==> refer to application software
filename.
– TDDVD580V02-ES ==> refer to application software
version.
