Error 13: RF Amp register write, and read data discord
Implement 8-bit shift operation of the 0x01 to the read-
able/writable register of the RF Amp. If once write data do
not accord with read data, it is NG.

(5-2) ARP Register Check

Data write

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 

t read, and accord check

Error 09: ARP 

Tt 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 (IC301) 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 

t other address read discord check

Error 10: ARP 

Tt 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 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

Write Data    : 00000000

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 

t 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 (IC301)
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.

Error 14: AVD RAM read data discord
The program code data stored in ROM (IC106) are copied
to all areas of RAM (IC404, 405) connected to the AVD
(IC403) 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 14, and the test
is suspended.
During the test, OSD display becomes blank as the OSD
area is also checked.

Normally, 

[0]

 is selected to adjust DVD (single layer), CD, and

DVD (dual layer) in this order. But, individual items can be ad-
justed for the case where adjustment is suspended due to an error.
In this mode, the adjustment can be made easily through the op-
eration following the message displayed on the screen. Which disc
is currently adjusted is displayed on the fluorescent display tube.

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, and [3]
DVD-DL disc are adjusted in this order. Because the changer model
can accept multiple discs in advance of adjustment, adjustments
can be continued by exchanging discs automatically whenever an
adjustment is completed following the instruction on screen. You
can exit the adjustment by pressing the

x

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 in-
sert a different type of disc.

Three kinds of discs can be set in advance. In this case, set discs in
order to the displayed number with following the massage. Every
time after adjusting a disc, the disc is replaced and adjustment is
continued automatically.
