CAUTION-1

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.

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.

2. Information on DVD-RAM Discs

2.1 Comparison of DVD-RAM Discs

The 4.7GB DVD-RAM is standardized as Version 2.0 with respect to the 2.6GB DVD-RAM (Version 1.0), and the major

differences are as follows:

The 8-cm DVD-RAM media is standardized as Version 2.1: It can be used with disc removed from cartridge as well as in

cartridge in the same way as with 12-cm DVD-RAM Type 2.

Notes: 1) In addition to the above, the 4.7GB DVD-RAM has a new defect control system to handle real time recording of

AV data.

2) Among the rewritable DVD standards, only the 4.7GB DVD-RAM is standardized for the 8cm size.

2.2 DVD Video Recording Standard

The DVD video recording standard is a newly established common standard to record video on DVD in real time. The DVD

video standard has already been used for read-only DVD, but it was previously exclusively for playback, so the following

were difficult:

Recording in real time

Addition or deletion of video/audio

Editing

The DVD video standard was reviewed to establish a DVD video recording standard which defines the devices for achieving

the characteristics inherent in disc, starting with the following, in addition to the capabilities of real-time recording and editing

on rewritable DVD media:

Note 2: There are two types of DVD-RAM: Disc used only while it is in cartridge (Type 1) and disc can be removed from

cartridge (Type2).

2.4 Available DVD- RAM Discs

There are two types of DVD-RAM disc: for video camera and for PCs. Be sure to use 8 cm DVD-RAM discs (1.4 GB on one

side, 2.8 GB on both sides) noted for video camera use (for AV) with this DVD video camera/recorder.

Most discs for video camera use (for AV) can be removed from their cartridges for recording. Some discs for PC, however,

cannot be removed from their cartridges, and some can be removed but recording cannot be made on them. For details, read

the instruction sheet provided with discs or consult the disc maker.

Examples of discs that cannot be used on this DVD video camera/recorder:

8 cm DVD-RAM discs for PC, CD, DVD-ROM, DVD-Video, MO, MD, iD, floppy disks,etc.

E1 - 4

2.5 Initializing (formatting) DVD- RAM Discs

This DVD video camera/recorder can use only DVD-RAM discs for AV formatted in accordance with the UDF 2.01 file system:

No recording can be made on an unformatted disc.

2.6 Handling DVD- RAM Disc

When the DVD-RAM disc is used for an extended period of time, the temperature will increase because of the heat

inside the DVD video camera/recorder: Be careful when removing the disc.

The DVD-RAM disc is a very delicate recording medium. Leave the disc in the cartridge when using it in this DVD

video camera/recorder.

Do not remove the disc from the cartridge unless needed, and do not open the shutter of cartridge.

Be sure not to touch disc surfaces.

Take great care so as not to scratch or stain disc.

Be careful not to allow the cartridge with disc to fall.

Be careful not to allow condensation.

To store disc cartridge, insert it in plastic case provided.

Do not place the disc cartridge in following places:

Where exposed to direct sunlight for a long time.

Where the humidity is high, or in dusty place.

Where exposed to heat from heater, etc.

Where there may be condensation.

2.7 Removing DVD- RAM Disc from Cartridge

Tip:

The side that will be recorded when SIDE A of disc faces the hand strap is the

opposite side to the "SIDE A" indication.

Cautions:

Most generally available 8 cm DVD- RAM discs can be removed from cartridges

if they are for video cameras; However, before removing disc from cartridge,

read the instruction sheet provided with the disc or consult the disc maker.

Take care with the following when handling the removed disc:

Be sure not to touch disc surfaces.

Be careful not to drop the disc removed from cartridge.

Be sure not to bend the disc.

Do not leave the disc outside the cartridge.

Do not subject the disc to heat.

Do not write on disc with a ball- point pen or pencil.

Be sure not to wipe disc surfaces with thinner,water or anti- static agent.

Use dry, soft cloth to lightly wipe off dust or dirt that adheres to the disc. Never use solvents to clean the disc.

If the disc is removed from cartridge and the data stored by this DVD video camera/recorder is rewritten on devices other

than this DVD video camera/recorder,recording or playback may not be normal,or Disc Navigation may not operate

normally,when the disc replaced in cartridge is used on this DVD video camera/recorder again.

The cartridge protects the surfaces of disc on which high- density recording is possible.Once removed from cartridge, the

disc can be replaced in the cartridge and used with this DVD video camera/recorder, but be sure to observe the

following:

Before replacing the disc in cartridge, make sure that disc surfaces are not scratched,and that no dirt or fingerprint

adheres to them.

Do not record,edit or delete on the disc when scratches, dirt or fingerprints cannot be removed even if disc surface is

cleaned.

When replacing the disc in cartridge, insert it until a click is heard.

Writing similar to recording is be performed even with simple editing or deletion. Make sure that editing or deletion has

been securely performed with the disc removed from cartridge.

Write-protect tabs

The DVD-RAM disc cartridge has write-protect tabs to prevent overwriting

on recorded data. Make sure that the write-protect tab is set to the side

where recording is possible.

Cautions:

Dust, scratches or dirt on the disc surface may cause block noise

because of the principle of disc recording. This does not indicate a fault.

Be careful when handling the disc so that no dirt or fingerprints adheres

to the disc.

This DVD video camera/recorder has a function that allows recording,

avoiding portions of the disc with dust, scratches or dirt [The DVD video

camera/recorder sets to pause ( ) status and automatically restarts

recording ( REC )] .

This will interrupt recording for several seconds to several minutes, and

multiple thumbnails will be created in one recording as shown in the

figure. In this case, the recordable time will decrease.

4. Explanation of Trouble Messages

A message may appear while you are operating the DVD video camera/recorder. If a message appears, refer to the following

table and take appropriate corrective action.

E1 - 10

Message

Cannot remove scenes

Cannot delete scenes

Please update disc

Reformat for camera

Continue?

Error on disc

All data will be deleted

Continue?

Cause

This may occur when

scene that was edited for

division, etc. is to be

unload.

This may occur when

scene that was edited for

division, etc. is to be

deleted.

The thumbnail at the start

of program or play list may

not appear when disc

edited on device other

than this DVD video

camera/recorder is used,

or, when editing, such as

combining, is performed on

this DVD video camera/

recorder.

The number of entered

scenes has reached the

limit that can be entered,

so the control information

for generating thumbnails

cannot be added.

Has the disc been initial-

ized on a PC?

Has initializing the disc on

a PC been interrupted?

Troubleshooting

Combine the divided scenes,

and then unload them.

Combine the divided scenes,

and then delete them.

If thumbnail is information is

insufficient, Disc Navigation

will automatically create

thumbnails after it starts.

Combine several scenes or

delete (unload) them.

Choose "Yes" and initialize the

disc when using it on this DVD

video camera/recorder.

Technical explanation

This appears if CELL is to be

divided (increased) when the

number of CELLs has reached

the limit of 999. (If recording

continues without editing on

this DVD video camera/

recorder, 1 scene will make up

1 EP or 1 CELL. If scenes are

combined, the number of EPs

will decrease, but the number

of CELLs will not decrease. If

CELL is to be divided at the

upper limit number of CELLs,

several scenes must be

deleted in this status without

traversing multiple CELLs. (*2)

Same as above.

This appears if a disc in which

EP is not attached to the

beginning of program or play

list is inserted (this occurs

when EP was not attached to

the beginning of program or

play list when editing was

performed on devices other

than this DVD video camera/

recorder, or scenes traversing

multiple programs were

combined, and thumbnails

cannot be displayed on Disc

Navigation screen). This

message appears when Disc

Navigation is started first after

power is supplied: Operation

following message instructions

will attach EP to the beginning

of program or play list, thereby

enabling thumbnails to be

displayed.

This appears if the number of

scenes has reached 999 when

control information is being

updated. (*1)

This appears if the disc has a

file that has been recorded in

a format that cannot be

detected by UDF2.0. (This

problem will be solved if the

disc is formatted on this DVD

video camera/recorder.)

This appears if the disc has

logically been destroyed. (The

problem frequently occurs

because of problem in the

UDF file system.) Although the

disc for which this message

appeared cannot be used as

is, it may be usable after it is

initialized (Note, however, that

all recorded data will be

deleted).

-----

The temperature inside the

DVD video camera/

recorder is too high, and

reading or writing of the

data on disc may not be

performed normally.

It is possible that the

system cannot normally

complete writing of file

when power is turned off

for some reason during

recording or editing

(deleting, dividing or

combining scenes, or

creating play list). Selecting

"Yes" will automatically

repair the video file, but

even if "No" is selected,

the same message will

appear when the DVD

video camera/recorder is

turned on next time. (Do

not remove the disc while

the DVD video camera/

recorder is recognizing it:

lqnoring this will deactivate

the file repair function.)

Troubleshooting

Remove the disc and wipe off

fingerprints, dust, etc. before

reusing it, or use another disc.

Turn off the DVD video

camera/recorder with the disc

being used in it, connect AC

adapter/charger, and then

power the DVD video camera/

recorder again. Scenes will be

repaired.

Delete unnecessary scenes

before using this disc, or use

another disc.

Turn the DVD video camera/

recorder off and wait for a

while. The temperature will be

effectively decreased if the

DVD video camera/recorder is

placed in a well-ventilated

spot.

Follow the instructions on

screen, taking note of the

following cautions:

Data may not be repaired,

depending on the timing

when power was turned off.

Data may not be repaired

normally if data recorded on

another recorder is mixed in.

The repaired data may be

different from the original

recorded content because of

partial deletion of defective

portion.

Since the date/time for repair

is added to the repaired data

(only the corrected portion

for partial repair), the original

date/time information will be

lost.

Since all movies, and then all

stills, are repaired, the order

of recorded contents will be

lost.

(In case of message (3) only)

Technical explanation

This appears if formatting of

disc could not be normally

performed (writing could not

be done to specified address).

This appears if power is shut

off for some reason during

movie recording. This DVD

video camera/recorder has a

function that automatically

saves files if power is shut off

during movie recording: This

function will repair some files

when the DVD video camera/

recorder is restarted (it may

take 10-20 minutes to repair

files). The DVD video camera/

recorder must be stably

powered using AC adapter for

restart.

This may appear if some

operation, such as adding

thumbnails, etc., is attempted

when the recordable area on

disc has been nearly used up.

This appears if recording,

playback, etc. is performed in

an environment near the limit

of allowable operating tem-

perature (humidity) for an

extended time. This message

will not appear in ordinary

situations of use, and reliability

of recorded data will decrease

in a situation where this

message appears.

*1: The number of recordable scenes on this DVD video camera/recorder is 999: Since the maximum number of EPs (record

ing points) defined by the RTR standard (DVD-RAM recording standard) is 999, and 1 EP is allocated to 1 scene, this

limitation exists.

*2: The number of recordable CELLs (minimum recording unit) on this DVD video camera/recorder is 999. This limitation

exists because the maximum number of CELLs defined by the RTR standard (DVD-RAM recording standard) is 999.

5. Troubleshooting Guide of DVD Video Camera/recorder

Cautions: 1) This DVD video camera/recorder incorporates a laser emitter block and high-voltage section:

Take great care when performing work.

2) Disassemble and reassemble the DVD video camera/recorder according to "Chapter 2 Disassembly".

Do not dismantle the R block any farther than the status shown in Fig. 5-1.

3) Be careful not to short-circuit TL (test land), IC pins, etc. during work.

4) Use the frame of ANA or DIG circuit board for GND.

The whole circuit board must be replaced in the following cases because components of these circuit boards are not available

as service parts. Judge whether the circuit boards shown below are defective, referring to the troubleshooting guide on the

following pages:

ANA circuit board

DIG circuit board

PHD circuit board [to be replaced together with mechanism unit] on R-block (drive block).

Notes: 1) Use the specified "check points" only for reference: Estimate the "Troubleshooting due to check results" method

from the "symptom" and try replacing circuit boards, components, etc., as needed.

If it is absolutely necessary to confirm check points, etc., pull them out from circuit boards using lead wires, etc.

2) This troubleshooting guide describes only major defects: The listed causes of defects and troubleshooting may not

always apply.

3) Troubleshooting guide assumes that connectors are correctly connected and that cables are not damaged or

disconnected: Make sure that all connectors and cables are correctly connected, and that they are not damaged.

4) This troubleshooting guide assumes that disc is normal. If there is any abnormality in disc, a trouble message will

appear: Perform appropriate troubleshooting, referring to “Explanation of Trouble Messages” described previously.

5) For check point locations, refer to the circuit board diagram shown in Chapter 6.
