Safety Instructions, Warnings, and Notes
2. Safety Instructions, Warnings, and Notes
EN 5SD-5.31SL 2.
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

Now start the terminal program. Make sure that the service-pin
(pin 1702-2) of the µP is pulled low.
The terminal program of your PC should now display: “DVDv6
Diagnostic software version ...”. This message already means
that the µP is running. This is also an indication that the first
basic nucleus (nucleus number 1) has been executed during
diagnostic start-up. The other commands can be carried out by
selecting the “command input” and simply type the reference
nbr. to do the test or select the “Menu - driven” test.
To be sure that the µP is able to run the diagnostic software,
serial port will be checked during start-up.

5.9.1 Menu Interface
The menu interface is part of the Level 2 / Second Line
diagnostic mode. Via the menu interface it is possible to control
the execution of the Diagnostic Nuclei.
Set-up Physical Interface Components
Hardware required:
• Service PC
• one free COM port on the Service PC
• special cable to connect DVD player to Service PC
The service PC must have a terminal emulation program (e.g.
OS2 WarpTerminal or Procomm /Windows Hyperterminal)
installed and must have a free COM port (e.g. COM1). Activate
the terminal emulation program and check that the port settings
for the free COM port are: 19200 bps, 8 data bits, no parity, 1
stop bit and no flow control. The free COM port must be
connected via a special cable to the RS232 port of the DVD
player. This special cable will also connect the test pin, which
is available on the connector, to ground (i.e. activate test pin).
Activation
Switch the player on and the following text will appear on the
screen of the terminal (program):

5.8 Overview of Interfaces
The table below shows an overview of the user interfaces of the
Diagnostic Software. The table is based on logical interface,
interfaces as seen from user perspective. A logical interface
can use one or more physical interface components. The DVD
has only a single RS232 port, implying that all interfaces using
this port are mutually exclusive.
