(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 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,

(3-7) ————— (Not supported)
(3-8) External RAM Check (External RAM installed model only)

(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 (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.

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 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 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.

The program code data stored in ROM (IC107) are copied
to all areas of RAM (IC504, IC505) connected to the AVD
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.

the FL display and DVD panel section.

The IF-89 board (IF CON) test mode is the IF CON self-diagnosis
mode. The IF CON can diagnose the functions of the IF-89 board
that the IF CON controls. Normally, the IF CON makes a serial
communication with the SYSTEM CONTROL and operates following the commands from the SYSTEM CONTROL, but in the
Test mode, the IF CON operates independently from the SYSTEM CONTROL.
In the test mode, the following functions can be checked.
1. Button function
2. Remote commander receiving function
3. SYSTEM CONTROL-IF CON serial communication
4. Click shuttle function
5. Fluorescent display tube lighting check
Grid check
Anode check

You cannot enter the Test mode when either button has been pressed
by any reason with the board assembled in the front panel. In this
state, the power does not turn on even under normal condition (the
unit is kept in standby state), and also no button is active and the
remote commander is not accepted. In this case, disconnect the
MB-103 board and AV-61 board, and with the SELF CHECK (pin
0) of IF CON (IC404) on the IF-89 board kept in low state, supply AC, and the IF CON self-diagnosis mode will be forcibly activated. The IF CON (IC404) checks the SELF CHECK port only
after the power on reset (only at AC supply, not in standby state).
If any button is pressed, its name is displayed on the fluorescent
display tube. But, if other than “NOTHING” is displayed though
no button is pressed, it means that any button has been pressed.

6-11-2. Faults in Test Mode (MB-103 board)
1. The test mode menu is not displayed.
1-1. Board visual check
Check that the ICs of SYSCON (IC104), ROM (IC106 or
IC107), AVD (IC403), ARP & SERVO (IC301) are working
correctly.
Check that outside appearance of the ICs is normal.
Check that IC pins are not short-circuited.
Check that there is no soldering error.
Check that outside appearance of the capacitors and resistors
is normal.

1-3-1. When the 8.25 MHz signal appears at CPUCK
• Check the XRD, XWRH and CS0X signal.
Observe XRD (pin-u;), XWRH (pin-ua), and CS0X (pin-tk)
of SYSCON (IC104) with an oscilloscope.
If these pins are fixed to either “L” (0V) or “H” (3.3V), or if
these pins stay in the center voltage, check the followings.
Check if the signal line does not have the defective soldering.
Check if the signal line is short-circuited with other signal
lines.
If you cannot find any problem t SYSCON (IC104) is
defective.
• HA [0 to 21] signal and HD [0 to 15] signal check
Observe HA [0 to 21] (pins-
