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.

1-2 Electrostatic Protection Measures

Semiconductor components, including optical pickups, may be damaged by static electricity charged
on clothes, human body, etc. Take great care when handling it to avoid electrostatic damage.

1-2-1 Grounding for prevention of electrostatic damage

Perform servicing in an environment where grounding is complete.

Grounding work bench (Fig. 1-2-1)

1) Lay out a conductive material (conductive sheet) or iron plate under the work bench on which
semiconductor components, such as optical pickups, are placed to ground the bench.

Grounding human body (Fig. 1-2-2)

1) Use an anti-static wrist strap to discharge static electricity charged on human body. Note,
however, that static electricity charged on clothes will not be discharged by anti-static wrist
strap: Be careful that your clothes do not touch the semiconductor components, such as optical
pickups.

1-2-2 Cautions when handling optical pickup - only for DVD products

1) The optical pickup has a high precision structure: Do not subject it to any impact.

2) Do not perform disassembly further than that described in this manual.

3) Never turn the semi-variable resistors in drive unit block.

Safety Precaution for Repair > Lead-Free Solder

1-3 Lead-Free Solder

To protect the global environment, lead-free solder is used in this product.
Be sure to read the following before soldering.

Caution

Be sure to wear protective goggles so that no solder smoke or scattered solder enters the eye
during servicing. Lead-free solder may scatter at high temperatures (600°C).

1-3-1 Characteristics of lead-free solder

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

Composition of alloy (wt%): Sn-3.0Ag-0.5Cu
Melting temperature: Approx. 220°C

1-3-2 Solder for servicing

It is recommended that you use lead-free solder whose characteristics are the same as that used in
this product, although it is also possible to service using lead based solder. However, if lead based
solder is used for servicing, some precautions are necessary. (Neglecting these could decrease
strength, causing malfunctions.)

Cautions when using lead based solder:
When replacing components, remove the lead-free solder previously used for soldered points as far as

possible.

For additional soldering, melt lead-free solder completely and mix well with lead based solder. Never

perform repair using the bare soldering iron tip without adding solder.

1-3-3 Soldering iron for servicing

It is recommended that you use a soldering iron with thermal control function, with which the
temperature at its tip can be set.
Lead-free solder melts at a temperature 30-40°C higher than lead based solder. Therefore,
workability will be reduced unless you use a soldering iron whose temperature is high, whose
temperature at tip does not change greatly (heat capacity is large), and that can be set to match the
work points.

Recommended soldering iron:
With thermal control function (temperature setting range: 320-450°C)

Recommended tip temperatures for different work points:

Work point

Circuit board with surface-mounted (chip) parts
Circuit board without surface-mounted (chip) parts
Chassis, metal shield

Recommended tip temperature

320°C ± 30°C
380°C ± 30°C
420°C ± 30°C

General Description

2-1 Overview

Model DV-RX5000U is the first Hitachi DVD video recorder.
The DV-RX5000U has a Time Navi function that allows user to designate the time of playback
scenes in 1-minute units, in addition to a Direct Navigation function that allows direct selection of
recorded images, thereby achieving the speedy, easy operability unique to disc.

2-1-1 Service method

For servicing the DV-RX5000U, repair only the exterior components that are assigned as service
parts: Do not attempt any other servicing besides that described in this manual.
Note that the servicing method may change as needed to improve serviceability: Pay attention to
the technical bulletins that will be periodically issued hereafter.

2-1-2 Disc information

2.8 GB, 8 cm (3")

We recommend using Hitachi Maxell discs as they have been con­firmed to be compatible with this unit. Other discs may not perform
correctly.
Do not allow the disc to become dirty or scratched. Fingerprints,
dirt, dust, scratches or deposits of cigarette smoke on the record­ing surface may make it impossible to use the disc for recording.
Discs with programs recorded in PAL already cannot be recorded
on using this unit.

play

DVD-RAM

DVD-RAM recorded on this unit may not be compatible with
other DVD players. Consult the manual for the player to deter­mine compatibility with these DVD-RAM discs.

This unit is compatible with both non-cartridge and car tridge
DVD-RAM, but the write-protect tabs on cartridge-type discs give
better protection to your recordings.
Picture aspect ratios, regular 4:3 or widescreen 16:9, are recorded
as they are received.

DVD- R

In order to play a DVD-R recorded using this unit on another
playback source, the disc must first be finalized .

Once a DVD-R is finalized, it becomes DVD-Video.
You can record onto the available space on the disc and perform
editing functions, such as giving titles to discs and programs and
erasing programs before finalizing.
When programming is erased from a DVD-R, that space does not
become available. Once an area on a DVD-R is recorded on, that
area is no longer available for recording, whether the recording is
erased or not.
It takes about 30 seconds for the unit to complete recording man­agement information after recording finishes.
This unit optimizes the DVD-R for each recording. Optimizing is
carried out when you start recording after inserting the disc or
turning on the unit. Recording onto the disc may become impossi­ble if optimizing is carried out too many times.
Play may be impossible in some cases due the condition of the
recording.
The video is recorded in a 4:3 aspect irrespective of the video sig­nal input.
