Disc Type Check

Judge automatically the loaded disc. As
the judged result is displayed at the bot-
tom of screen, make sure that it is cor-
rect.
If Disc Check Memory menu has not
been executed after EEPROM default
setting, the disc type cannot be judged.
In this case, return to the initial menu
and make a check for three types of
discs (SL, DL, CD).

On this screen, the servo on/off control necessary for replay is
executed. Normally, turn on each servo from 1 sequentially and
when CLVA is turned on, the usual trace mode becomes active. In
the trace mode, DVD sector address or CD time code is displayed.
This is not displayed where the spindle is not locked.
The spindle could run overriding the control if the spindle system
is faulty or RF is not present. In such a case, do not operate CLVA.

page. 2/2

On this screen, current servo adjusted data stored in the EEPROM
are displayed. The adjusted data are initialized by pressing the

[CLEAR]

 key, but be careful that they are not recoverable after

initialization.
Before clearing the adjusted data, make a note of the set data. This
screen will also appear if 

[0]

 All is selected in the Drive Auto

Adjustment. In this case, default setting cannot be made.
For reference, the drive has been designed so that the gain center
value is 20 and offset value is 80. Other values will be in a range
of 10 to 80. If extreme value such as 00 or FF is set, adjustment
will be faulty. In such a case, check for disc scratch or cable dis-
connection, then perform adjustment again.

### Mecha Aging ###

The ROM version, region code, OPT type, etc. are displayed if

 is selected in the Test Mode Menu.

The parenthesized hexadecimal number in the version number field
indicates the checksum value of the ROM.

Note : After down loading ROM data, sometimes it happens that

checksum is not the same as that of ROM data which has
been down loaded. In such a case, go back to the menu
and select “0. Syscon Diagnosis”, then select “1. All” in
“2. Version”. If the result of this operation does not give
an agreement, it must be either Down Load error or ROM
error.

On the Test Mode Menu screen, selecting

appears but the menu screen will be restored if pressing any key.

The front board test mode is the IF CON self diagnostic mode.
The IF CON can diagnose the functions of the front panel boards
that the IF CON controls. Normally, the IF CON makes a serial
communication with the SYSTEM CONTROL and operates fol-
lowing the commands from the SYSTEM CONTROL, but in the
Test mode, the IF CON operates independently from the SYS-
TEM CONTROL.

In the Test mode, the following functions can be checked.
1. Button function
2. Remote commander receiving function
3. SYSTEM CONTROL-IF CON serial communication
4. Click shuttle function
5. Fluorescent display tube lighting check

Grid check
Anode check

6. LED control function

In the Test mode, the set operates same as usual, except voltage
monitoring, communication monitoring, display of fluorescent
display tube, and LED control.
1. The routine that monitors +3.3 V (P-CONT) of MB-98 board

is not provided.

2. The monitoring timer for serial communication with the SYS-

TEM CONTROL is not provided. The set is not placed in the
Standby mode, even if the communication with SYSTEM
CONTROL is normal.

3. Display of fluorescent display tube (normally, display is made

following the commands from SYSTEM CONTROL)

4. LED control (normally, control is made following the com-

mands from SYSTEM CONTROL)

The Self Check mode is the function to conduct the basic test to
the FL display and DVD panel section.

At the AC Power ON after IF CON (IC404) was reset, the input to
10pin (SELF CHECK) is judged and if “Low” is entered, the main
unit transits to the Self Check mode. In this port input judgment,
the result of 3-time attempts must be same (assuming that the MB-
98 board is not connected). While pressing the 

[STOP]

 key on the

main unit with the IF CON in STANDBY mode, enter 

[RETURN]

 

→

[DISPLAY]

 (or 

[SET UP]

) on the remote commander, and the unit

transits to the Self Check Mode. The Self Check mode terminates
when the IF CON transits to the STANDBY mode.
