unless an error is found, but at a certain item that requires judgment through a visual check to the result, the following screen is
displayed for the key entry.
Press the x key to quit the diagnosis, or [PREV] key to repeat
the same item where an error occurred, or [NEXT] key to continue
the check from the item next to faulty item.
Selecting 2 and subsequent items calls the submenu screen of each

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 (IC701), 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
(IC801, IC802). If mechanical deck is connected, the motor and optics could be damaged. Disconnect mechanical
deck following the output message, then enter specified 4or 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 CN002 and CN003
of MB board. Also, disconnect harness from the CN013 of
MB board.
5. Supply
Caution: Do not conduct this check with a mechanical deck con-
nected.
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.
Supplement: How to disconnect mechanical deck
Disconnect flat cables connected to the CN002 and
CN003 of MB board. Also, disconnect harness from
the CN013 of MB board.
3. Peripheral
(3-2) Gate Array Check
Data write → read, and accord check
Error 02: Gate array write/read discord
Data 0x00~0xFF are written to the address 0xF of gate array
(IC601), then read and checked if they accord.
(3-3) 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 (IC201), then read and checked.
Before writing, the data are saved, then after checking, they
are written to restore the contents of EEPROM.
(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 (address 0xC6) in ARP (IC303), 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 (IC304) connected to the
ARP (IC303) 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.

HCD-DP1000D
(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 (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. The following display, 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 implies that these addresses are in the form of shadow. Also,
if the read data is not 0xA55A, another error will be present.
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 (IC206) are copied
to all areas of RAM (IC402, IC403) connected to the AVD
(IC401) 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.
(6-3) 1930 SP
ROM → AVD RAM → Video OUT
Error: Not detected.
The data including sub picture streams in ROM (IC206)
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).
7. Video
(7-2) Color Bar
AVD color bar command write → Video OUT
Error: Not detected.
The command is transferred to the AVD, and the color bar
signals are output from video terminals.
They are output from all video terminals (Composite, Y/C).
8. Audio
(8-2) ARP → 1930
Error 14: ARP → 1930 video NG
15 : ARP → 1930 audio NG
(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.
