PREVENTION OF ELECTRO STATIC DISCHARGE
The laser diode in the DVD mechanism may be damaged due to static electricity from clothes or the human body. Use caution
to prevent electro static damage when servicing or handling the DVD-mechanism.
1. Grounding for electro static damage prevention
Some devices, such as the DVD player, use an optical pickup (laser diode) that will be damaged by static electricity in the
working environment. Only attempt service after ensuring that all grounding procedures have been completed.
Put a grounded conductive material (sheet) or iron sheet on the area where the optical pickup is placed.
Use an anti-static wrist strap to discharge the static electricity from your body.

Warning for power supply
The primary side of the power supply carries live mains voltage when the player is connected to the mains even when
the player is switched off !
This primary area is not shielded so it is possible to touch copper tracks and/or components when servicing the player.
Service personnel have to take precautions to prevent touching this area or components in this area .
The primary side of the power supply has been indicated with a lightening stroke and a stripe-marked print on the printed wiring
board.
Note:
The screws on the DVD mechanism (position 50 in on the exploded view drawing) may never be touched, removed or
re-adjusted.
Handle the DVD mechanism with care when the unit has to be exchanged!
The DVD mechanism is very sensitive for dropping or giving shocks.
