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.

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 > Lead-Free Solder

1-4 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.

General Description > Overview
About DVD-R and DVD-RW disc
How are DVD-R and DVD-RW discs different?
The essential difference between DVD-R and DVD-RW is that DVD-R is a record-once medium, while DVD-RW is a re-recordable/erasable medium. You can re-record/ erase a DVD-RW disc approximately 1,000 times.
Can I play my recordable discs in a regular DVD player?
Generally, DVD-R discs and DVD-RW discs recorded in Video mode are playable in a regular DVD player, but they must be ‘finalized’ first. This process fixes the contents of the disc to make them readable to other DVD players as DVD-Video discs. DVD-RW discs recorded in VR (Video Recording) mode are playable in some players.
This indicates a product feature that is capable of playing DVD-RW discs recorded with Video Recording format.
What are ‘recording modes’?
There are two recording modes available using this recorder: VR mode and Video mode. When recording to a DVD-R disc, recordings are always in Video mode. DVD-RW discs can be formatted for VR mode recording or Video mode recording.
VR mode recording
• 4 different picture quality/recording time settings available (XP, SP, LP, EP)
• Not playable on regular DVD players
• Recordings can be extensively edited
Video mode recording
• 4 different picture quality/recording time settings available (XP, SP, LP, EP)
• Playable on regular DVD players (after finalizing)
• Limited editing features
Is editing a DVD like editing a video tape?
No. When you edit a video tape you need one video deck to play the original tape and another to record the edits. With DVD, you edit by making a ‘Playlist’ of what to play and when to play it. On playback, the recorder plays the disc according to the Playlist.
About word ‘Original’ and ‘Playlist’
Throughout this manual, you will often see the words Original and Playlist to refer to the actual content and the edited version.
Original: content refers to what’s actually recorded on the disc.
Playlist: content refers to the edited version of the disc — how the Original content is to be played.
About DVD+R and DVD+RW disc
How are DVD+R and DVD+RW discs different?
The essential difference between DVD+R and DVD+RW is that DVD+R is a record-once medium, while DVD+RW is a re-recordable/erasable medium. You can re-record/ erase a DVD+RW disc approximately 1,000 times.
DVD+RW mode recording
• 4 different picture quality/recording time settings available (XP, SP, LP, EP)
• Playable on regular DVD players
• The edited contents is playable on regular DVD players only after finalizing
• Recordings can be edited the title/chapter
DVD+R mode recording
• 4 different picture quality/recording time settings available (XP, SP, LP, EP)
• Playable on regular DVD players (after finalizing)
• Any edited contents are not be compatible on regular DVD players. (Hide, chapter combine, added chapter mark, etc.)
• Limited title/chapter editing features
ote
DVD-Video Format (Video mode) is a new format for recording on DVD-R/RW and DVD+R/RW discs that was approved by the DVD Forum in 2000. You may therefore experience problems playing recordable DVD discs in some players. Symptoms include video artifacts, audio and/or video dropouts and playback suddenly stopping. Our company cannot take responsibility for problems playing discs recorded on this recorder in other players.

See Dolby AC3. 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. Digital Versatile Disc. A huge amount of digital data for video (movie) and audio can be recorded on this disc, whose size is the same as CD. One type of DVD standard disc, on which high-quality audio can be recorded One type of DVD standard disc, to which writing once is possible (recordable type) One type of DVD standard disc, to which writing up to 100,000 times is possible One type of DVD standard disc, to which writing up to 1000 times is possible One type of DVD standard disc, on which high-quality video and audio can be recorded Video recording/playback standard that applies to DVD-Video, DVD-R and DVD­RW Video recording/playback standard that applies to DVD-RAM and DVD-RW: This allows versatile editing functions, differing from the DVD Video Format. 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.

Explanation
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. Secure Digital Music Initiative: This conference was established by hardware makers, the Recording Industry Association of America (RIAA) and music industry companies, to protect copyrights of musical compositions. To make adjustment for clearer playback image, by reducing noise that appears on screen during videotape playback.
