Information on MAN-H/MAN, DRV-R, MOD
and HDM Circuit Boards
If a fault is located on the MAN-H/MAN circuit
board, the entire circuit board must be replaced
for servicing.
If there is a fault in the DRV-R, MOD or HDM
circuit board, the entire disc drive unit must be
replaced, since these circuit boards are
included in this unit.
Because of this servicing method, this service
manual does not include any schematic circuit
diagrams.
For circuit board diagrams, the manual
includes the simple diagrams, which show only
the information that is necessary for
troubleshooting.

Safety Precaution for Repair
1
1-1 Cautions
Many electrical and mechanical parts have special safety-related characteristics. These are often not
evident from visual inspection nor can the protection afforded by them necessarily be obtained by using
replacement components rated for a higher voltage, wattage, etc. Replacement parts which have these
special safety characteristics are identified in this Service Manual. Electrical components having such
features are identified by marking with a
on the schematics and the parts list in this Service Manual.
The use of a substitute replacement component which does not have the same safety characteristics as
the HITACHI recommended replacement one, shown in the parts list in this Service Manual, may create
shock, fire, or other hazards. Product safety is continuously under review and new instructions are issued
from time to time. For the latest information, always consult the current HITACHI Service Manual. A
subscription to, or additional copies for, HITACHI Service Manual may be obtained at a nominal charge
from HITACHI SALES CORPORATION.
PRODUCT SAFETY NOTICE
CAUTION
There is a high-voltage section inside the DVD video
camera/recorder: When repairing or inspecting it, take
great care to prevent electric shock: Use an isolating
transformer, wear gloves, etc.
CLASS 1
LASER PROCTECT
CAUTION
This product contains a laser diode of
higher class than 1. To ensure contin-
ued safety, do not remove any covers
or attempt to gain access to the in-
side of the product. Refer all servicing
to qualified personnel.
CAUTION CLASS 2M LASER RADIATION WHEN OPEN
DO NOT STARE INTO THE BEAM OR VIEW
DIRECTLY WITH OPTICAL INSTRUMENTS.
Lithium battery; danger of explosion if battery is incorrectly replaced. Replace only with the same or
equivalent type recommended by the equipment manufacturer. Discard used batteries according to
manufacturer's instructions.
When replacing the lithium battery it is important to use the same type and connect it correctly.
WARNING:
Lithium batteries contain dangerous chemicals.
Handle and dispose of with great care.
Do not throw in a fire.
Do not short circuit it.
For disposal place in a plastic bag and put in waste bin.
CAUTION
CAUTION (COLOR LCD)
LCD display; the liquid crystal display (LCD) panel is mode by highly precise technology.
More than 99.99% of its picture elements (pixels) are effective, but some (less than 0.01%) may appear
as colored bright dots. This mode not indicate a fault as the LCD panel stretches the limits of current
technology.
