1. SERVICE PRECAUTIONS
1.1 SERVICE PRECAUTIONS
1.2 NOTES ON SOLDERING
1. You should conform to the regulations govering the product (safety, radio and noise, and other regulations),
and should keep the safety during servicing by following the safety instructions described in this manual.
2. Be careful about an internal sharp edge.
3. Be careful in handling ICs. Some ICs such as MOS type are so fragile that they can be damaged by
electrostatic induction.
4. Be careful in handing made from metal parts. There might be burr at the edge of it.
5. Two kinds of resetting are available
1) Press RESET Button at the lower left of Front Panel.
Without entire initialization.
Microcomputer restarting (emergency resetting at function trouble) .
2) Perform [Default Setting] initialization in System Menu
Perform product initialization except a part of items.
Please carry it out when updating software.
6. Any component parts in the DVD Mechanism Module of this model can not be supplied.
If you need to replace any parts in the DVD Mechanism Module, replace whole of DVD Mechanism Module.
7. The sheet (121490000888) fixing a flexible cable onto the DVD mechanism is not reusable.
If you removed this sheet, replace it with the new one.
8. Disc Removal Method At No Power
You can add a about 3V-4V DC voltage between "Load+"(Red) with "Load-"(White).
Press [RESET] with a pen tip or other pointed
instrument.
RESET
White : Load-
Red : Load+
For environmental protection, lead-free solder is used on the printed circuit boards mounted in this unit.
Be sure to use lead-free solder and a soldering iron that can meet specifications for use with lead-free solders for repairs
accompanied by reworking of soldering.
Compared with conventional eutectic solders, lead-free solders have higher melting points, by approximately 40 C.
Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 C in general, although
the temperature depends on the heat capacity of the PC board on which reworking is required and the weight of the tip of
the soldering iron.
Compared with eutectic solders, lead-free solders have higher bond strengths but slower wetting times and higher melting
temperatures (hard to melt/easy to harden).
The following lead-free solders are available as service parts:
Parts numbers of lead-free solder:
GYP1006 1.0 in dia.
GYP1007 0.6 in dia.
GYP1008 0.3 in dia.
