Caution: Do not conduct this check with a mechanical deck connected. An access is made to the stream supply and servo control IC (IC303) and external RAM (IC304) 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.

(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 (IC304) 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.
(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 (IC304) connected to the ARP (IC303) 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

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.
(6-3) 1930 SP ROM > AVD RAM > Video OUT Error: Not detected. The data including sub picture streams in ROM (IC205) are transferred to the RAM (IC402, IC403) in AVD (IC401), and output as video signals from the AVD (IC401). They are output from all video terminals (Composite, Y/C).

DRIVE AUTO ADJUSTMENT
On the Test Mode Menu screen, press [ 1 ] key on
the remote commander, and the drive auto adjustment menu will be displayed. Normally, [ 0 ] is selected to adjust DVD (single
layer), CD, DVD (dual layer), and 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. The disc used for adjustment must be the one specified
for adjustment. However, for SACD disc, use the player with initial data if the
disc is not available.
0. ALL
Select [ 0 ] and press [ E N T E R ] key, and the servo set data in EEPROM will be initialized. Then, 1. DVD-SL disc, 2. CD disc, 3. DVD-DL disc, and 4. SACD disc are adjusted in this order. Each time one disc was adjusted, it is ejected. Replace it with the specified disc following the message. Though the message to confirm whether discs other than SACD disc are adjusted is not displayed, you can finish the adjustment if pressing the [ S T O P ] button. During adjustment of each disc, the measurement for disc type judgment is made. As automatic adjustment does not judge the disc type unlike conventional models, take care not to insert wrong type discs. Also, do not give a shock during adjustment
