Version
(2-2) Revision
ROM revision number is displayed.-
Error: Not detected.
The revision number defined in the source file of ROM (At
the beginning of mass production, the Flash ROM of IC107
is used, but midway it is replaced by the IC108 OTP ROM.
IC107 or IC108) is displayed with four digits.
Below IC107 are all IC107 or IC108.
(2-3) ROM Check Sum
Check sum is calculated.
Error: Not detected.
The 8-bit data are added at addresses 0x000F0000 ~
0x002EFFFF of ROM (IC107) and the result is displayed
with 4-digit hexadecimal number. Error is not detected.
Compare the result with the specified value.
(2-4) Model Type
Model code is displayed.
Error: Not detected.
The model code read from EEPROM (IC101) is displayed
with 2-digit hexadecimal number.

Peripheral
(3-2) EEPROM Check
Data write 
→ read, and accord check
Error 03: EEPROM write/read discord
Data 0x9249, 0x2942, 0x4294 are written to addresses
0x00~0xFF of EEPROM (IC101), then read and checked.
Before writing, the data are saved, then after checking, they
are written to restore the contents of EEPROM.
4.
Servo
(4-2) Servo DSP Check
Data write 
→ read, and accord check
Error 12: Read data discord
Data 0x9249, 0x2942, 0x4294 are written to the address
0x602 of RAM in the Servo DSP (IC302), then read and
checked.
(4-3) DSP Driver Test
Test signal data 
→ DSP Driver
Error: Not detected.
Caution: Do not conduct this test with a mechanical deck
connected.
The maximum voltage is applied to the Servo Driver IC
(IC401, IC802). If mechanical deck is connected, the mo-
tor and optics could be damaged. Disconnect mechanical
deck following the output message, then enter specified 4-
or 5-digit number from the remote commander, and press
the 
[ENTER]
. The test is conducted only when the input
data accord. Check the output level, then press the 
[NEXT]
to finish the test.
This test is skipped if “All” is selected.
Supplement: How to disconnect mechanical deck
Disconnect flat cables connected to the CN009 and CN010
of MB-82/85 board. Also, disconnect harness from the
CN402.
5.
Supply
Caution: Do  not conduct this check with a mechanical deck
connected.
An access is made to the stream supply and servo control
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 flat cables connected to the CN009 and
CN010 of DVD board. Also, disconnect harness from
the CN402.
(5-2) ARP Register Check
Data write 
→ read, and accord check
Error 08: ARP register write, and read data discord
Data 0x00 to 0xFF are written to the TMAX register (ad-
dress 0xC6) in ARP (IC302), then they are read and checked.
(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.
(5-4) ARP to RAM Address Bus
Data write 
→ other address read discord check
Error 10: ARP 
→ RAM address bus error
Caution: Address and data display in case of an error is
different from the display of other diagnosis (de-
scribed later).
Before starting the test, all addresses of RAM (IC303) are
cleared to 0x0000.
First, 0xA55A is written to the address 0x00000, and the
address data are read and checked from addresses 0x00001
to 0x80000 while shifting 1 bit each. Next, the data at that
address is cleared, and it is written to the address 0x00001,
and read and checked in the same manner. This check is
repeated up to the address 0x80000 while shifting the ad-
dress data by 1 bit each.
If data other than 0 is read at the addresses except written
address, an error is given because all addresses were al-
ready cleared to 0. In this check, the error display pattern is
different from that of other diagnosis; read data, written
address, and read address are displayed in this order. How-
ever, the message uses same template, and accordingly ex-
change Address and Data when reading. The following dis-
play, for example,
### Syscon Diagnosis ###
 5-4. ARP to RAM Address Bus
Error 10: ARP - RAM Address B
Address
: 0000A55A
Write Data : 00000000
Read Data
: 00080000
Press NEXT Key to Continue
Press PREV Key to Repeat
_
shows the data 0xA55A was read from address 0x00080000
though it was written to the address 0x00000000. This im-
plies that these addresses are in the form of shadow. Also,
if the read data is not 0xA55A, another error will be present.
(5-5) ARP RAM Check
Data write 
→ read, and accord check
Error 11: ARP RAM read data discord
The program code data stored in ROM are copied to all
areas of RAM (IC303) connected to the ARP (IC302)
through the bus, then they are read and checked if they ac-
cord. If the detail check was selected initially, the data are
written to all areas and read, then the same test is conducted
once again with the data where all bits are inverted between
1 and 0. If discord is detected, faulty address, written data,
and read data are displayed following the error code 11,
and the test is suspended.

AV Decoder
(6-2) 1930 RAM
Data write

Error 13: AVD RAM read data discord
The program code data stored in ROM (IC107 or IC108)
are copied to all areas oo»RAM (IC504, IC505) connected
to the AVD (IC503) through the bus, then they are read and
checked if they accord. Further, the same test is conducted
once again with the data where all bits are inverted between
1 and 0. If discord is detected, faulty address, written data,
and read data are displayed following the error code 13,
and the test is suspended.
