Data write à 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.
- DSP Driver Test
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 motor 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.
[Disconnect flat cables
connected to the CN009 and CN010 of MB-82/85 board. Also, disconnect harness
from the CN402.]
- Supply
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.
[Disconnect flat cables
connected to the CN009 and
CN010 of DVD board. Also,
disconnect harness from the CN402.]
- ARP Register Check
Error 08: ARP register write,
and read data discord
Data 0x00 to 0xFF are written to the TMAX
register (address 0xC6) in ARP (IC302), then they are read and checked.- ARP to RAM Data Bus
Error 09: ARP ß-> 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.
- ARP to RAM Address Bus
Error 10: ARP à 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.
- ARP RAM 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.
- AV Decoder
Data write à read, and accord check
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.
- 1930 SP

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.
- ALL
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 x 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.
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.

In using the manual operation
menu, take care of the following points. These commands do not provide
protection, thus requiring correct operation. The sector address or time code
field is displayed
when a disc is loaded.
1. Set correctly the disc
type to be used on the Disc Type screen.
The disc type must be set after a disc was loaded. The set disc type is cleared when the tray
is opened.
2. After power ON, if the
Drive Manual Operation was selected, first perform “Reset SLED TILT” by opening
1. Disc Type screen.
3. In case of an alarm,
immediately press the [Stop] button to stop the servo operation, and turn the
power OFF.
