Safety Precaution for Repair

1-1 Cautions

PRODUCT SAFETY NOTICE

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.

CAUTION

There is a high-voltage section inside the DVD video

recorder. When repairing or inspecting it, take great care

to prevent electric shock: Use an isolating transformer,

CAUTION

This product contains a laser diode of
higher class than 1. To ensure contin­ued safety, do not remove any covers
or attempt to gain access to the in­side of the product. Refer all servicing
to qualified personnel.

wear gloves, etc.

Safety Precaution for Repair > Electrostatic Protection Measures / Cautions When Handling DVD Drive

1-2 Electrostatic Protection Measures

Semiconductor components can be damaged by static electricity charged on clothes, human body,
etc. Take great care when handling components to avoid electrostatic damage, and perform
servicing in an environment where grounding is complete.

(1) Grounding work bench

Lay out an antistatic mat on work bench, and then use the ground plate to ground the work bench.

Antistatic mat

1M ohm

Ground

(2) Grounding human body

Use an antistatic wrist strap to discharge any static electricity charged on the body. Also, use a
tester for wrist strap to make sure that the wrist strap is working normally. Note, however, that
static electricity charged on clothes will not be discharged by wrist strap: Therefore do not allow
your clothes to touch the semiconductor components.

Antistatic wrist strap

1M ohm

1-3 Cautions When Handling DVD Drive

The optical pickup in DVD drive has a high precision structure: Be sure to observe the following
cautions.

1) Do not subject optical pickups to any severe vibrations or
impact during movement, installation or disassembly.

2) When performing repair work, do not perform disassembly
any further than that described in this manual.

3) Never turn the semi-variable resistors for adjustment in
optical pickup or DVD drive.

4) NEVER look into the objective lens in optical pickup or
directly view the laser light: You could lose your eyesight.

Do not directly look at laser light
from pickup.

Safety Precaution for Repair > Cautions When Handling HDD (Hard Disk Drive)

1-4 Cautions When Handling HDD (Hard Disk Drive)

HDD is a high precision device, and is very susceptible to vibrations or impact. Even if HDD
operates normally immediately after it has been subjected to vibrations or impact, a problem may
occur after it is used for a while: When servicing, take great care with the following.
There are two types of HDD: CSS format (head remains on disk regardless of operation status) and
ramp loading format (head moves away from disk during no operation). The impact resistance
characteristics are slightly different for the two. When servicing, observe the following cautions
regardless of the format:

(1) Cautions during unpacking

1) Do not subject the HDD to any impact when placing on desk: The head hitting against the desk
could result in damage.

2) If condensation occurs because of the environment, leave the HDD without being turned on for at
least 3 hours until it adapts to surrounding environment. If the HDD is turned on while the head
is sticking to disk because of condensation, the disk may be damaged.

(2) Cautions during transportation

An HDD is more susceptible to vibrations or impact when it is turned on or operating than during
no operation.

1) Do not move the HDD while it is turned on: If the HDD is subject to any impact while the disk is
rotating, i.e., the head hitting against the disk, breakage could result.

2) Move the HDD approximately 2 minutes (approximately 30 seconds for surveillance system
devices) after turning it off and unplugging its power cord from AC outlet. The disk will still be
rotating by inertia immediately after the HDD is turned off: Subjecting the HDD to movement at
this time could destroy it.

(3) Cautions during operation

1) Do not unplug the power cord from AC outlet during operation: This could damage the data on
HDD. Be sure to turn the HDD off before unplugging the power cord.

2) Do not hit the HDD: The head hitting the disk could result in breakage.

(4) Caution during packing

1) Use the packing material of relevant model: Material superior in impact resistance is used. Using
other packing materials could result in fault.

(5) Cautions when handling unassembled HDD

1) Hold the HDD at both sides so that the circuit board surface is facing below: Holding the HDD at
the top and bottom could cause the head to drift, which could result in fault.

2) Do not touch the terminal or pattern on circuit board.

3) Place HDD on a spot where cushion is pasted with the circuit board surface facing below.

4) Do not hold or place stacked HDDs.

5) Do not drop or hit HDD against anything: Dropping HDD from even 5 mm high on a work bench
with high stiffness could cause fault.

Safety Precaution for Repair > Lead-Free Solder

1-5 Lead-Free Solder

The printed circuit board that uses lead-free solder is adopted. To protect the global environment,
use the recommended lead-free solder also during servicing.
Read and observe the following before soldering:

Caution

ALWAYS wear protective goggles during soldering so that no solder smoke or scattered solder
enters the eye. Lead-free solder may scatter at high temperatures of 600°C.

(1) Characteristics of lead-free solder

The melting point of lead-free solder is 30-40°C higher than that of lead based solder.

(2) Lead-free solder for servicing

Use the following lead-free solder for servicing:
Recommended lead-free solder and composition of alloy (wt%): Sn-3.0Ag-0.5Cu or equivalent

Information:

For composition of alloy, Sn is tin; Ag is silver; Cu is copper; Bi is bismuth; Pb is lead.

(3) Soldering iron for servicing

The temperature of soldering iron tip must be adjusted according to the points to be soldered: Use
an antistatic soldering iron with thermal control function.
When removing components, take care not to damage any surrounding component or pattern. When
attaching components, observe the heating time in the following table so that the components are
not destroyed by heat.

Tip temperatures for different soldering points:

Point to be soldered

Surface-mounted (chip) parts [other than
those shown below]
Surface-mounted (chip) parts [for DVD
cameras, cellular phones only]
Discrete parts
Chassis, metal shield, etc.

320 ± 30°C
[heating time: less than 5 seconds]
350 ± 10°C
[heating time: less than 3 seconds]
380 ± 30°C
420 ± 30°C

Tip temperature

(4) Cautions when using lead based solder

It is recommended that you use lead-free solder when servicing, but it is also possible to service
using lead based solder. However, if lead based solder is used for servicing, take care with the
following:

1) Before using lead based solder, remove the lead-free solder completely from the point to be
soldered.

2) For additional soldering for repair, set the soldering iron tip temperature for lead-free solder, mix
lead based solder and lead-free solder sufficiently. Do not perform any repair using the bare
soldering iron tip without adding solder, since it will cause secondary failure due to lack of
strength.

About HDMI

HDMI (High Definition Multimedia Interface) supports
both video and audio on a single digital connection for
use with DVD Players, Set-Top Boxes, and other AV
devices.
HDMI was developed to provide the technologies of
HDCP (High-bandwidth Digital Content Protection).
HDCP is used to protect digital content transmitted
and received.

HDMI has the capability to support standard,
enhanced, or high-definition video plus standard to
multi-channel surround-sound audio, HDMI features
include uncompressed digital video, a bandwidth of up
to 5 gigabytes per second, one connector (instead of
several cables and connectors), and communication
between the AV source and AV devices such as
DTVs.

HDMI, the HDMI logo and High-Definition Multimedia
Interface are trademarks or registered trademarks of
HDMI licensing LLC.

Additional Information for HDMI

• When you connect a HDMI or DVI compatible
device make sure of the followings:

-Try switching off the HDMI/DVI device and this

recorder. Next, switch on the HDMI/DVI device
and leave it for around 30 seconds, then switch
on this recorder.

- The connected device’s video input is set correctly

for this unit.

- The connected device is compatible with

720(1440)x576i or 720x576 progressive video
input.

• Not all HDCP-compatible DVI devices will work with
this recorder.

- It’s impossible copy protected-DVD title’s playback

in non-HDCP devices.

• If you select the HDMI output, outputs other than
digital tuner output - such as D1/D2/D3 video out­puts, component video outputs, S1 video output and
video output (from yellow jack) - cannot be dis­played.

Function to correct the gradations on dark portions to make dark scenes easier­to-see.
Content Protection for Recordable Media: Copyright protection function that is
suitable for online distribution of music.
One type of DVD standard disc, to which writing once is possible (recordable
type)
One type of CD standard disc, to which writing up to 1000 times is possible
Used for outputs of HDTV video signal format. Since signals for brightness and
colors are independently handled for components signals (Y: luminance signal;
PR/PB: chrominance signals), degrading of image will be reduced.
A device that decodes the data coded and recorded on DVD Video and restores it
to video and audio signals. This processing is referred to as decoding.
A difference between maximum and minimum levels of audio recorded on disc:
Measured in decibel (dB) units. If the dynamic range is compressed (audio DRC),
the minimum signal level will increase and the maximum signal level will
decrease: This will reduce the higher audio signal - such as burst sound - so that
the low-level audio signal - such as human voice - can be heard more clearly.
Audio coding format developed by Dolby Laboratories in U.S, also simply
referred as AC3 format: Supports 5-channel full-range sound and one channel
for sub-woofer sound playback.
Dynamic Range Control: Adjusting the audio range of maximum and minimum
levels (dynamic range) will improve audio signal when, for example, dialog is
hard to hear or user is watching movies late at night.
Digital Theater System: Sound system as for movie theaters developed by US
Digital Theater Systems, Inc. The number of channels provided by DTS is the
same for Dolby AC3.

Explanation

DVD recorders normally use data that is common between images, and
individually record different data for each image.
I-picture: Images recorded independently for the reference of commonly used
data.
P-picture: Images created from past I-picture or P-picture
B-picture: Images created from both I and P pictures, which interact between
both types
Since I-picture delivers the highest image quality, selecting I-picture is
recommended when adjusting image quality.
Joint Photographic Expert Group: International standard format for
compressing still images.
Moving Picture Experts Group: Standard related to compression of digital video
and audio. MPEG2 is a higher standard of MPEG and is applied to video (movie)
requiring higher quality.
One of three audio compression standards (layers 1-3) defined by MPEG

MPEG1 Audio Layer-3: Audio data digital compression technology.
Audio is usually converted to an electrical signal and transmitted from DVD to a
device such as amp: When audio is converted to a digital signal, this optical
digital audio output can be transmitted on optical fiber.
Most DVD videos are produced assuming that they will be displayed on wide TV
screen (aspect ratio of 16:9): If they are displayed on TV screens with 4:3 aspect
ratio, 16:9 images will not quite fit on 4:3 screens. There are two ways of
displaying 16:9 images on 4:3 TV:

· Pan & Scan: Cuts out the left and right ends of images and displays them on
whole screen.

· Letterbox: Reproduces 16:9 images on 4:3 screens with black bands across the
top and bottom of screen.

One format to play Video CD: User can select desired screens and data while
watching the displayed menu screen.
This function converts interlaced images to non-interlaced images and displays
them. It can play back 24-frame/second images included in DVD movie software,
etc.
The video signal is separated into chrominance (C) and luminance (L) signals
and transmitted to TV: This delivers clearer images.
Sampling slices audio waves (analog signal) at a specified time interval, and
digitizes the levels of the sliced waves. The slicing number per second is referred
to as the sampling frequency: The higher the number, the closer the sound to
the original.
Windows Media Audio: Codec that was developed by Microsoft Corporation in
USA.
This technology localizes sound at any position using only two front speakers, by
subjecting the L and R signals to matrix operation. It uses the four transfer
functions from L/R speakers located at specified positions to both ears of listener
located in a specified position, taking into account the shape of head and the
effect of earlobes, and the two transfer functions from any position to both ears.
