Submenu
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.
0. Quit
Quit the submenu and return to the main menu.
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
automatically unless an error is found.
Selecting 2 and subsequent items executes respective menus and
outputs the results.
For the contents of each submenu, see “General Description of
Checking Method” and “Check Items List”.

EEPROM Check
Data write 
→ read, and accord check
Error 03: EEPROM write/read discord
0x9249, 0x2942 and 0x4294 are written to the address
0x00 to 0xFF of the EEPROM and then read for
checking. 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
0x9249, 0x2942 and 0x4294 are written to the RAM
address 0x602 of the Servo DSP and then read for
checking.
Also, OPT type “1 LASER” or “2 LASER” is displayed.

Error: Not detected.
Caution: Do not perform this checking with the mechanical deck
connected.
The maximum voltage is applied to the Servo Driver IC
(IC401). If the mechanical deck is connected, it will be
destroyed immediately. Following the output message,
disconnect the mechanical deck, then enter the
specified 4- or 5-digit value from the commander, and
press the 
[ENTER]
 key. The test is conducted only if
the entered value accords. To exit the test, check the
output level, then press 
[NEXT]
 key.
This check is not conducted, but skipped in “All” menu
item.

(5-2)
ARP Register Check
Data write 
→ read, and accord check
Error 08: ARP register write, and read data discord
Data 0x00 to 0xFF is written sequentially to the ARP
TMAX register (address 0xC6) and then read for
checking.
(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
(described 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 address 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
already 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. However, the message uses same template, and
accordingly exchange Address and Data when reading.
The following display, for example, shows the data
0xA55A was read from address 0x00080000 though it
was written to the address 0x00000000. This implies 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
accord. 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.
6. AV Decoder
(6-2)
1930 RAM
Data write 
→ read, and accord check
Error 13: AVD RAM read data discord
The program code data stored in ROM (IC107) are copied
to all areas of 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.
During the test, OSD display becomes blank as the OSD
area is also checked.

6-4. DRIVE AUTO ADJUSTMENT
On the Test Mode Menu screen, press 
[1]
 key on the remote
commander, and the drive auto adjustment menu will be dis-
played.
Normally, 
[0]
 is selected to adjust DVD (single layer), CD, DVD
(dual layer), and LCD (SACD) in this order. But, individual items
can be adjusted for the case where adjustment is suspended due to
an error. In this mode, the adjustment can be made easily through
the operation following the message displayed on the screen.
Which disc is currently adjusted is displayed on the fluorescent
display tube.
The disc used for adjustment must be the one specified for
adjustment.
0. ALL
You will be asked if EEPROM data are initialized or not, and for
this prompt, select 
[0]
 and press the 
[ENTER]
 key. First, the
servo setting data in EEPROM, Emergency History and Hour
Meter are cleared to initialize. Then, 1. DVD-SL disc, 2. CD disc,
3. DVD-DL disc, and 4. LCD disc (SACD disc) are adjusted in
this order. Each time one disc was adjusted, it is ejected, and
therefore exchange the disc following the message. Though the
message to confirm whether the discs is to be adjusted is not
displayed except for LCD disk (SACD disk), you can exit the
adjustment by pressing the 
[STOP]
 button. In adjusting each
disc, the mirror time is measured to check the disk type. In the
auto adjustment, whether the disc type is correct is not checked
unlike conventional models, and accordingly, take care not to
insert a different type of disc.
1. DVD-SL (single layer)
Select 
[1]
, insert DVD single layer disc, and press 
[ENTER]
 key,
and the adjustment will be made through the following steps, then
adjusted values will be written to the EEPROM.
