What are "regional codes"?
Motion picture studios want to control the home release of movies in different countries because theater releases arenit
simultaneous (a movie may come out on DVD in the US when itis just hitting screens in Europe). Therefore they have
required that the DVD standard include codes which can be used to lock out the playback of certain discs in certain geo-graphical
regions. Players sold in each region will have that regionis code built into the player. The player will refuse to play
these "region coded" discs which are not allowed in the region. However, regional codes are entirely optional. Discs without
codes will play on any player in any country. Some studios have already announced that only their new releases will have
regional codes. There are six regions:
1. United States and Canada 2. Europe and Japan
3. Far East (except Japan & China) 4. South America and Oceania
5. Africa and the Middle East 6. China (except Hong Kong)

REGION CODE
THE DISCS THAT THE DV7000 CAN HANDLE
The following discs can be played back with a DV7000.
Note: The regional code of the discs must meet to the regional
code of the DV7000.
DVD INFORMATION
Below is a glossary of the new terms related to DVD.
Title:
A disc may have more than one story/movie on it, so each
story/movie is called a "title".
For example, if there are 2 movies on the disc, they are
separated into Title 1 and Title 2.
Chapter:
A title may also be separated into chapters.
For example, a movie (title) may be separated into 3 scenes
(chapters).
Subtitles:
DVDs are recorded with up to 32 different subtitle languages.
If a disc has more than one subtitle language, you can select
the subtitle language that you want to read.
Soundtrack language:
DVDs are recorded with up to 8 different soundtrack languages.
If a disc has more than one language, you can select the
soundtrack language that you want to listen to.
Multi-angles:
On some DVDs, scenes have been filmed from different angles
(up to a maximum of 9). On these discs, you can select the
angle that you want to watch. Please refer to the DVD's manual
to see which scenes have multi-angles.
Cancelling password for parental press the DIMMER button

5. DISASSEMBLY
1. Open the tray and remove the escutcheon (050B).
REMARK : If the tray doesn't work, put a small
screwdriver into the hole as shown in picture
and slide the knob. Then the tray comes out.
After the first centimeter it is possible to pull
the tray out by hand. (see fig.1)
2. Remove 6 screws and remove the top cover.
3. Remove a top right side screw on the power supply PCB
and remove the GND lug wire.
4. Remove 3 connectors of the wire harness from (or to )
front panel assembly.
5. Remove 2 screws of left and right side of the front panel
assembly.
6. Remove the front panel assembly.
7. Remove the retainer on the DVD mechanism.
8. Remove FFC and wire harness from the DVD main PCB
which mounted under the DVD mechanism.
9. Remove 4 screws and remove DVD mechanism module.

6-1-1. Removal of the MECHANISM BLOCK
1) Turn the unit's power on and press the "EJECT" button to
eject the DISC TRAY.
2) Disconnect the power cord and remove the DISC CLAMPER
BLOCK.
3) Completely remove the DISC TRAY by pulling it outwards
while pulling up both of the stopper tabs alternately.
Fig. 6-1
4) Disconnect the two flat cables from the P803 connectors
and one flat cable from the P808 connector on the MAIN
PCB.
5) Disconnect the P807 connector on the MAIN PCB.
6) Remove the four a retaining screws and remove the
MECHANISM BLOCK from the chassis.

6. REPLACEMENT OF PRINCIPAL COMPONENTS
6-1-2. Removal of the TRAVERSE MECHA.
1) Remove the four b screws on the MAIN PCB and then
disconnect the P800 connector on the MAIN PCB.
Fig. 6-3
2) Short the laser diode protection circuit on the PICK UP
BLOCKÕs flexible cable with solder as shown.
Caution
To protect the laser diode from damage caused by high voltage
static electricity, a laser diode protection circuit has to be
shorted before disconnecting the flexible cable (P200 connector
on the MECHANISM PCB). It is recommended that you put
solder on the top of the soldering iron as shown in Fig. 3-5
then short the circuit at once.When you replace theTRAVERSE
MECHA., be sure to connect the P200 connector before
removing the solder at the shorted parts.

3) Carefully disconnect the two connectors (P500, P600) and
the two flat cables (P200, P300) on the MECHANISM PCB.
Fig. 6-6
4) Using tweezers, release the four retaining HOOKs of the
TRAVERSE MECHA. from the rubber insulators being
careful not to damage the rubber insulators.
Fig. 6-7
5) Remove the TRAVERSE MECHA. from the MECHANISM
BLOCK.
6) Reassemble in the reverse order for installation. Never
remove the solder on the flexible cable before connecting
the P200 connector on the MECHANISM PCB.
6-2. Replacement of the SPINDLE MOTOR
Because the SPINDLE MOTOR position is very critical, jitter
adjustment should be performed after replacement.
1) Disconnect the P300 connector on the MECHANISM PCB.
2) Insert a Philips type screw driver into the hole on the TURN
TABLE of the SPINDLE MOTOR and remove the two
screws.
6-3. Replacement of the PICK UP BLOCK
Replacement of the PICK UP BLOCK itself is not
recommended because its azimuth adjustment is very
critical and requires a special jig. If PICK UP BLOCK
replacement is necessary, replace with an entire
TRAVERSE MECHANISM only.

8-1. DVD JITTER ADJUSTMENT
1. Stick the provided small round sticker (0.1 mm thickness) at
the innermost position of a DVD disc as shown and make a
swayed DVD disc.
Fig. 8-2
2. Play back the swayed DVD disc and press the F.F button
repeatedly until the pickup block reaches the outermost
position of its movable range. Next, press the PAUSE button.
3. Set the oscilloscope to the DC input mode and connect it to
the TP201 (HOT) and the TP102 (D.GND) on the MAIN
PCB.
4. Adjust the a screw and b screw alternately so that the AC
and DC level of the waveform is minimum. (DC level should
be less than 1.8 V, AC component should be minimum.)
Fig. 8-3
NOTE: If the SPINDLE MOTOR is replaced, this jitter
adjustment should be performed for proper performance.
8-2. SLICE LEVEL ADJUSTMENT
1. Play back an ordinary DVD disc (single side, one layer) and
press the F.F button repeatedly until the pickup block reaches
almost the center position of its movable range.
2. Set the oscilloscope to the DC input mode and connect it to
the TP201 (HOT) and the TP102 (D.GND) on the MAIN
PCB.
3. Adjust the VR202 so that the DC level is minimum. (The DC
level should be less than 1.8 V)
8-3. CD TRACKING BALANCE
1. Set the VR110 at its center position prior to the adjustment.
2. Connect an oscilloscope to the TP150 (TE) on the MAIN
PCB.
3. Play back an ordinary CD-disc and then set it to the PAUSE
mode. If the play mode does not be engage, turn the VR110
at ±15 degrees. If the play mode does still not be engage
even when the VR110 is turned at ±15 degrees, turn the
VR110 at ± 30 degrees and try it again.
4. Observe the waveform and adjust it so that the level A of the
waveform is the same as level B.

Test point : TP107(+), TP120 (+) TP105 (GND)
Equipment : Digital Multi Meter (DC voltage)
1. Press the mains switch (POWER BUTTON) while depressing
the PLAY button and STOP button.
2. Status will be on the TEST mode 2 and FL display shows
<TEST 2>. After a couple of seconds FL display shows
<TEST2 OK>.
3. Press the button. Then the FL display shows <E3 02>
and the status will be in AS adjustment mode.
4. Measure the DC voltage at the test point TP107.
5. Press the button again. Then the DVD laser will light ON
and the FL display shows <E3 00>.
6. Press the button again. Then the CD laser will light ON
and the FL display shows <E3 01>.
7. Adjust the voltage at the test point TP120 by VR121, that the
value must be same as TP107 (10mV) value measured on
#4. process.
8. Press the button twice of time. Then the DVD laser will
light ON and the FL display shows <E3 00>.
9. Measure the DC voltage at the status DVD laser light ON.
Adjust the voltage at that status 35mV (±10mV) lower than
“CD laser light ON “status by the trim resister VR120.
10.Press the button again. Confirm the DC voltage at the
status CD laser light ON.
(DC voltage must be 35mV higher than the status DVD
laser light ON.)
11.Power OFF the mains switch (POWER BUTTON).
