GENERAL DESCRIPTION
The Test Mode allows you to make diagnosis and adjustment eas-
ily using the remote commander and monitor TV. The instructions,
diagnostic results, etc. are given on the on-screen display (OSD).

STARTING TEST  MODE
At the bottom of menu screen, the model name and revision num-
ber are displayed. The “T table” that appers on the screen means
the turn table.
To execute each function, select the desired menu and press its
number on the remote commander.
To exit from the Test Mode, press the POWER button.

SYSCON DIAGNOSIS
The same contents as board detail check by serial interface can be
checked from the remote commander.
On the Test Mode Menu screen, press 
[0]
 key on the remote com-
mander, and the following check menu will be displayed.

1. All
All items continuous check
This menu checks all diagnostic items continuously. Normally, all
items are checked successively one after another automatically
unless an error is found, but at a certain item that requires judg-
ment through a visual check to the result, the following screen is
displayed for the key entry.
### Syscon Diagnosis ###
Diag All Check
No. 2 Version
 2-3. ROM Check Sum
Check Sum = xxxx
Press NEXT Key to Continue
Press PREV Key to Repeat
_
For the ROM Check, the check sum calculated by the Syscon is
output, and therefore you must compare it with the specified value
for confirmation.
Following the message, press 
[NEXT]
 key to go to the next item,
or 
[PREV]
 key to repeat the same check again. To quit the diagno-
sis and return to the Check Menu screen, press 
[STOP]
 or
[ENTER]
 key. If an error occurred, the diagnosis is suspended
and the error code is displayed as shown below.
### Syscon Diagnosis ###
 3-2. EEPROM Check
Error 03: EEPROM Write/Reed N

Press 
[STOP]
 key to quit the diagnosis, or 
[PREV]
 key to repeat
the same item where an error occurred, or 
[NEXT]
 key to continue
the check from the item next to faulty item.
Subnemu
Selecting 2 and subsequent items calls the submenu screen of each
item.
For example, if “5. Supply” is selected, the following submenu
will be displayed.

General Description of Checking Method
2. Version
(2-2) Revision
ROM revision number is displayed.
Error: Not detected.
The revision number defined in the source file of ROM
(IC106) is displayed with four digits.
(2-3) ROM Check Sum
Check sum is calculated.
Error: Not detected.
The data are added of ROM (IC106) and the result is dis-
played with 4-digit hexadecimal number. Error is not de-
tected. Compare the result with the specified value.
(2-4) Model Type
Model code is displayed.
Error: Not detected.
The model code is displayed with 2-digit hexadecimal num-
ber.

(2-5) Region
Region code is displayed.
Error: Not detected.
The region code determined from the model code is dis-
played.
3. Peripheral
(3-2) EEPROM Check
Data write 
 read, and accord check
Error 03: EEPROM write/read discord
Before writing, the data are saved, then after checking, they
are written to restore the contents of EEPROM.
(3-3) Gate Array Check
Data write 
 read, and accord check
Error 02: Gate array write/read discord
4. Servo
(4-2) Servo DSP Check
Data write 
 read, and accord check
Error 12: Read data discord
(4-3) DSP Driver Test
Test signal data 
 DSP Driver
Error: Not detected.
5. Supply
Caution: Do not conduct this check with a mechanical deck con-
nected.
An access is made to the stream supply and servo con-
trol IC (IC302) and external RAM (IC303) using check
data. If mechanical deck is connected, the motor and
optics could be damaged. This check is also executed by
the “All” menu item.
Supplement: How to disconnect mechanical deck
Disconnect flexible flat cables connected to the
CN201 and CN202 of MB-86 board. Also, discon-
nect flat cable from the CN401.
(5-2) ARP Register Check
Data write 
 read, and accord check
Error 08: ARP register write, and read data discord
(5-3) ARP to RAM Data Bus
Data write 
 read, and accord check
Error 09: ARP 
←→
 RAM data bus error
Data 0x0001 to 0x8000 where one bit each is set to 1 are
written to the address 0 of RAM (IC303) connected to the
ARP (IC302) through the bus, then they are read and
checked. In case of discord, written bit pattern and read
data are displayed. If data where multiple bits are 1 are
read, the bits concerned may touch each other. Further, if
data where certain bit is always 1 or 0 regardless of written
data, the line could be disconnected or shorted.
1. All
All submenu items continuous check
This menu checks 2 and subsequent items successively. At the item
where visual check is required for judgment or an error occurred,
the checking is suspended and the message is output for key entry.
Normally, all items are checked successively one after another au-
tomatically unless an error is found.
Selecting 2 and subsequent items executes respective menus and
outputs the results.
For the contents of each submenu, see “Check Items List”.
