Cautionary Notes
Before beginning the procedure, please read
through this document. The matters described may
differ according to the model.
Back Up User Data!
User data may be lost during the course of the procedure. Refer to Saving and
Loading Data(p. 16) in the Service Notes and save the data. After completing
the procedure, restore the backed-up data to the product.
Part Replacement
When replacing components near the power-supply circuit or a heatgenerating
circuit (such as a circuit provided with a heat sink or including a cement
resistor), carry out the procedure according to the instructions with respect to
the part number, direction, and attachment position (mounting so as to leave
an air gap between the component and the circuit board, etc.).
Parts List
A component whose part code is ******** cannot be supplied as a service part
because one of the following reasons applies.
• Because it is supplied as an assembled part (under a different part code).
• Because a number of circuit boards are grouped together and supplied as
a single circuit board (under a different part code).
• Because supply is prohibited due to copyright restrictions.
• Because reissuance is restricted.
• Because the part is made to order (at current market price).
Circuit Diagram
In the circuit diagram, “NIU” is an abbreviation for “Not in Use,” and
“UnPop” is an abbreviation for “Unpopulated.” They both mean non-mounted
components. The circuit board and circuit board diagram show silk-screened
indications, but no components are mounted.

Important Notes When Replacing the T-Bar
The T-bar Assembly (#71789367) is available as an older type (1-A in the
figure) and a new type (1-B). The older type has a back fitting attached.
Similarly, the Shield Cover (#05121512) is also available as an older type (11-A)
and a new type (11-B). The older type has a wider opening.
When replacing the older-type T-bar Assembly (1-A) with the new type (1-B),
be sure to also replace the older-type Shield Cover (11-A) with the new type
(11-B).
That is to say, the new type of T-bar Assembly (1-B) must not be used in
combination with the older type of Shield Cover (11-A). Refer to the following
chart for the specific combinations that are acceptable.
* Only the new types (1-B and 11-B) are suppled as service parts.
T-bar Assembly Shield Cover Production numbers of
products where used
1-A 11-A Through ZW90699
1-B 11-B ZX00700 and after T-bar Assembly Shield Cover Combination possible
1-A 11-A Good
1-A 11-B Good
1-B 11-A Not good
1-B 11-B Good

Verifying the Version
Number
1. Using a video cable, connect the PREVIEW OUT jack on the V-8 to the
video input jack on the television monitor.
2. Hold down the [MENU] and [ENTER] buttons and press the [POWER]
switch.
* Continue to hold down the [MENU] and [ENTER] buttons until the Test Mode
menu screen appears.
V-8 Test Mode appears on the television monitor, and the version
number is displayed on the right side of the top line.
Saving and Loading Data
Saving Data
You save the setting data stored on the unit to an external MIDI sequencer or
computer installed with a MIDI-sequencing program (“MIDI sequencer”) by
sending the setting data to it as MIDI data (bulk dump).
* When youíre using an external MIDI sequencer, set the device IDs for the V-8
and the external MIDI sequencer to the same value. To set the device ID for the
V-8, go to the MIDI Setup menu and make the setting for Device ID.
1. Connect the MIDI OUT/THRU connector on the V-8 and the MIDI IN
connector on the MIDI sequencer.
2. Operate the MIDI sequencer to enable it to receive MIDI data.
3. Press the [MENU] button to display the menu, choose MIDI Setup, then
press the [ENTER] button.
4. Use [ ] or [ ] to choose MIDI Bulk Dump, then press the [ENTER]
button.
5. Start recording on the MIDI sequencer.
6. Use [ ] or [ ] to choose Yes, then press the [ENTER] button.
The MIDI data is sent from the V-8.
* To cancel, either press the [MENU] button, or select No and press the [ENTER]
button.
7. Stop recording on the MIDI sequencer.
8. Press the [MENU] button several times to make the menu disappear.
Loading Data
This imports setting data saved on a MIDI sequencer into the V-8.
* When youíre using the V-8 with an external MIDI sequencer, check to make
sure that the device IDs for both are using the same setting. To set the device ID
for the V-8, go to the MIDI Setup menu and make the setting for Device ID.
* Under Utility, set Memory Protect to OFF.
1. Connect the MIDI IN connector on the V-8 with the MIDI OUT connector
on the MIDI sequencer.
2. Start playback on the MIDI sequencer.
MIDI data is sent from the MIDI sequencer. When the V-8 receives the
MIDI data, the settings are overwritten.
3. Stop playback on the MIDI sequencer.
Performing a Factory Reset
Hold down the EFFECTS-A [1 FEEDBACK] and [4 MULTI] buttons and press
the [POWER] switch.
FAC appears on the display and a factory reset is executed.
When the factory reset finishes, the V-8 starts up.
* The Test Mode settings 01: Tbar SET(p. 18) and 02: Contrast SET(p. 18)
and the color system (NTSC or PAL) are not initialized. For each, the setting in
effect before the factory reset is retained.
How to Initialize
Unlike a factory reset, performing initialization initializes the Test mode 01:
Tbar SET(p. 18) and 02: Contrast SET(p. 18) settings. Also, the color system
is set to NTSC.
* When the circuit board has been replaced, be sure to execute initialization.
To perform initialization, hold down the [1 MIX], [BPM SYNC], and
[TRANSFORMER B] buttons and press the [POWER] switch.
Int appears on the display for several seconds, after which ntSC is displayed,
and the V-8 starts up.
* To ensure correct operation of the V-8ís video faders, after initialization, execute
the Test Mode’s 01: Tbar SET(p. 18) and 02: Contrast SET(p. 18).
Changing the Color System
At powerup, the V-8ís display shows the color system.
When the color system is NTSC, the characters ntSC are displayed, scrolling
from right to left.
When the color system is PAL, PAL is displayed.
After the color system is displayed, the V-8 starts up.
To change the color system, hold down the PREVIEW OUTPUT SELECT [1]
and [OUTPUT] buttons and press the [POWER] switch.
If the color system before powerup was NTSC, PAL is displayed, the color
system is set to PAL, and the unit starts up.
If the color system before powerup was PAL, ntSC is displayed, the color
system is set to NTSC, and the unit starts up.

How to Update the System
The system can be updated by receiving the update data containing the
programming (SMF format) as MIDI data.
Items Required
• Computer installed with a MIDI sequencer (UpdSMF, etc.)
• USB-MIDI interface (UM-1EX, etc.)
• MIDI cable and USB cable
• Update data (obtained via Service Net)
Procedure
1. Copy the update data to the computer.
The update data is made up of files like the following.
V-8_01.mid, V-8_02.mid,..., V-8_16.mid
* The number of files may vary, depending on the version.
2. Connect the computer and the V-8 via the USB-MIDI interface.
3. Set the [MEMORY] control on the V-8 to 1.
4. Hold down the [TRANSFORMER A], [1 MIX], and [TRANSFORMER B]
buttons at the same time and press the [POWER] switch.
The [ENTER] button flashes and nld is displayed.
5. Press the [ENTER] button.
Ers is displayed, and after a short while, the display changes to ---.
6. On the MIDI sequencer, play back the update files in numerical order (V-
8_01.mid, V-8_02.mid,..., V-8_16.mid).
The display shows 000, and this value is then incremented.
Updating the system takes approximately 6minutes.
When the update finishes, CnP is displayed.
7. Switch off the power to the V-8.
* When you have updated the system after replacing the circuit board, be sure to
execute initialization. Also, execute the Test Mode and make the settings for 01:
Tbar SET(p. 18) and 02: Contrast SET(p. 18). The color system is set to
NTSC after initialization. If necessary, change this to PAL.
* When only a system update has been performed, carry out only a factory reset,
without executing initialization.
