• SHUTTLE on the remote commander during Grid Test display

(This model does not provide JOG/SHUTTLE, and therefore
use another DVD remote commander having the JOG/
SHUTTLE)

The Self Check mode transits to this mode when 

[UP]

 key is en-

tered. The first grid of FLD all turns on and other grids turn off.
Each time the SHUTTLE is entered, the grid is switched in order.
When SHUTTLE input is clockwise, the grid switches in 1 

→ 

2

→ 

3 direction, or counterclockwise it switches in 3 

→ 

2 

→ 

1 direc-

tion. This tests whether each grid turns on individually.

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
set is kept in standby state), and also no button is active and the
remote commander is not accepted. In this case, disconnect the
MB-98 board and with the SELF CHECK (0 pin) of IF CON
(IC404) on the AI-24 board kept in low state, supply AC, and the
Test mode will be forcibly activated. Or, on the board, short the
land printed as “SELF” to enter the Test mode. 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.

1. Test mode menu is not displayed
• Board visual check

Check main IC’s, SYSTEM CONTROL (IC103), ROM (IC107
or IC108), AVD (IC503), and ARP&SERVO (IC302), for mount-
ing condition, direction, or evidence of short between pins, or
soldering failure. Also, compare with good board to check if
there are missing capacitors or resistors.

• Clock signal check

Measure the clock frequency at CPUCK (uj pin) of the SYS-
TEM CONTROL (IC103) using an oscilloscope.
If 33 MHz is outputted, an access to the ROM is normal, and
then check the items in 1-2.
In the case of 8.25 MHz output, check the items in 1-1.
If it is fixed to “H” or “L”, the X101 or SYSTEM CONTROL
(IC103) will be faulty.

1-1. CPUCK (33 MHz) is not outputted
• Power supply voltage check

Check the power connectors of the boards or power input pins
of the IC’s for voltage. Check the IC’s in order of SYSTEM
CONTROL (IC103), ROM (IC107 or IC108), AVD (IC503), and
ARP&SERVO (IC302). If correct voltage is not outputted, the
power line will be shorted, or soldering or IC will be faulty.

• Reset signal check

Check that the XFRRST (uh pin) of SYSTEM CONTROL
(IC103) is “H” (3.3 V). If not “H”, a soldering failure of that
line, a shot with other line, or faulty SYSTEM CONTROL
(IC103) is doubtful.

• XRD, XWRH, and CS0X signals check

Using an oscilloscope, measure the XRD (u; pin), XWRH (ua
pin), and CS0X (tk pin) of the SYSTEM CONTROL (IC103)
to check if they are fixed to “L” (0 V) or “H” (3.3 V), or if they
are on the intermediate potential between “L” and “H”. If they
are fixed to “L” or “H”, or on the intermediate potential, a sol-
dering failure of that line, a shot with other line, or faulty SYS-
TEM CONTROL (IC103) is doubtful.

• HA [0 – 21] and HD [0 – 15] signals check

Using an oscilloscope, measure the HA [0 

–

 21] (<z/x> – <z/.>, <zzz> –

<zz,>

, <zx/>, 1 – 5 pins) and HD [0 

–

 15] (ig – <z//> pins) of the

SYSTEM CONTROL (IC103) to check if they are fixed to “L”
(0 V) or “H” (3.3 V), or if HA is on the intermediate potential
between “L” and “H” (HD is on intermediate potential in nor-
mal state), or if same waveform as that of adjacent pins is mea-
sured. In case of “L” or “H”, intermediate potential, or same
waveform, a soldering failure of that line, a shot with other line,
or faulty SYSTEM CONTROL (IC103) is doubtful.

• AVD (IC503) check

Using an oscilloscope, measure the SDCLKO (<zv.> pin) of the
AVD (IC503) to check that 95 MHz is outputted. If not output-
ted, a short of 27 MHz line across CLKI (<z,/> pin) and SCLKIN
(<z,x> pin), IC mounting failure, or faulty AVD (IC503) is doubt-
ful. If 27 MHz is outputted, the communication between SYS-
TEM CONTROL (IC103) and AVD (IC503) is disabled, and
therefore check the following items, particularly the AVD
(IC503).

• WAIT signal check

Using an oscilloscope, measure the XWAIT (yj pin) of the SYS-
TEM CONTROL (IC103) to check if it is fixed to “L” (0 V) or
on the intermediate potential. In case of “L” or intermediate
potential, examine CS2X 

–

 CS5X (y; – yd pins) to check if any

pin is fixed to “L”.
For the CS2X and CS3X, AVD (IC503) mounting failure or faulty
IC is doubtful.
For the CS4X and CS5X, ARP&SERVO (IC302) mounting fail-
ure or faulty IC is doubtful.
If CS2X 

–

 CS5X are not “L”, or they are sometimes on interme-

diate potential, a soldering failure of XWAIT line, a short with
other line, or faulty SYSTEM CONTROL (IC103) is doubtful.

• INT signal check

Using an oscilloscope, measure the INT0 

–

 2, 4 

–

 6 (qh – qk

pins, w; – ws pins) of the SYSTEM CONTROL (IC103) to check
if INT0 

–

 2, and 6 are fixed to “L” (0 V) and INT5 is fixed to

“H” (3.3 V), or they are on intermediate potential. In case of
“L”, “H”, or intermediate potential, a soldering failure of IC’s
connected to that line, a short with other line, faulty SYSTEM
CONTROL (IC103), or faulty each IC is doubtful.
INT0

: AVD (IC503)

INT1, INT2 : ARP&SERVO (IC302)
INT5, INT6 : AUDIO DSP (IC701)

• CSnX signals check

Using an oscilloscope, measure the CX0X 

–

 CX7X (tk – yd,

yg

, yh pins) of the SYSTEM CONTROL (IC103) to check if

they are fixed to “L” (0 V), or two or more CS’s sometime go
“L”, or on intermediate potential. In case of fixed “L”, two or
more CS’s on “L” or intermediate potential, a soldering failure
of IC’s connected to that line, a short with other line, faulty
SYSTEM CONTROL (IC103), or faulty each IC is doubtful.
CS0X

: ROM (IC107 or IC108)

CS2X, CS3X: AVD (IC503)
CS4X, CS5X: ARP&SERVO (IC302)

• Other CS signals check

Using an oscilloscope, measure the VESCS/X39CS (i; pin) and
XDACS (ul pin) of the SYSTEM CONTROL (IC103) to check
if they are fixed to “L”. If fixed, a soldering failure of that line,
a short with other line, or faulty SYSTEM CONTROL (IC103)
is doubtful.

If the above checking could not find a fault, check the outputted
CS signal. If CS signal other than CS0X is outputted, a mounting
failure of each IC or faulty IC that corresponds to active CS signal
is doubtful.

CS2X, CS3X: AVD (IC503)
CS4X, CS5X: ARP&SERVO (IC302)

Using an oscilloscope, measure the PLCKO (og pin) of the ARP&
SERVO (IC302) to check if it is fixed to “L” (0 V) or “H” (3.3 V).
If fixed to “L” or “H”, the ARP&SERVO (IC302) is faulty. If not
fixed, check the items in 1-2. in order.

A mounting failure of IC or faulty IC for that item is doubtful.
If “1901NG” is displayed, a loose connection of CN801, mount-
ing failure of AUDIO DSP (IC701), or faulty IC is doubtful.

Check the CN801 for connection, and the flat cable for damage or
loose connection.

A mounting failure of AUDIO DSP (IC801) or AUDIO DAC
(IC802, IC803), power supply failure, or faulty IC is doubtful.

Using an oscilloscope, measure the yd,  yh,  yl,  uf,  uj, and i;
pins of AVD (IC503) to check if analog signals are outputted re-
spectively. If not outputted, a soldering failure of that line, a short
with other line, missing capacitor or resistor, or faulty AVD is
doubtful.

Faulty analog circuits of ARP&SERVO (IC302) or faulty periph-
eral circuits of DIGITAL SERVO (IC202) on the MB-98 board,
faulty optical pickup, or loose connection of flat cable is doubtful.

If Syscon Diagnosis completed successfully, basically the boards
other than MB-98 board, connection, optical pickup, or mechani-
cal deck will be faulty.

Check if the specified voltage is outputted from the EVER 

–

11 V

(3 pin), EVER +3.3 V (qa pin), and EVER +11 V (qd pin) of
CN201 or CN920 in the power supply block. If not outputted, the
power supply block will be faulty.

[POWER]

Check if the specified voltage is outputted from the EVER 

–

11 V

(3 pin), EVER +3.3 V (qa pin), and EVER +11 V (qd pin) of
CN201 or CN920 in the power supply block. If not outputted, the
power supply block will be faulty.
Check the P-CONT (2 pin) of CN401 on the AI-24 board if it
becomes “H”. If not “H”, a soldering failure of that line, a short
with other line, missing capacitor or resistor, faulty AVD (IC503),
loose connection between power supply block and AI-24 board,
loose connection of connectors, faulty power supply block, or faulty
AI-24 board is doubtful.

[POWER]

There is no regularity between faulty parts and timing when the
set returns to the standby state).
Check if the specified voltage is outputted from the power supply
block. If not outputted, the power supply block will be faulty.
Check the XFRRST (9 pin) of CN101 on the MB-98 board if it is
fixed to “L”, or the XIBUSY (0 pin), XIFCS (qa pin), SI0 (qs
pin), SO0 (qd pin) and SC0 (qf pin) of CN101 if they are fixed to
“L” or “H”.
If fixed to “L” or “H”, a soldering failure of that line, a short with
other line, missing capacitor or resistor, or faulty AVD (IC503) is
doubtful.
If not fixed to “L” or “H”, loose connection between power sup-
ply block and AI-24 board or between AI-24 board and MB-98
board, loose connection of connectors, or faulty AI-24 board is
doubtful.

[POWER]

Loose connection between power supply block and AI-24 board,
loose connection of connectors, or faulty AI-24 board is doubtful.

Loose connection between power supply block and AI-24 board
or between AI-24 board and MB-98 board, loose connection of
connectors, or faulty AI-24 board is doubtful.

A mounting failure of BNR (IC601) on the MB-98 board, or faulty
AVD (IC503) or ARP&SERVO (IC302), or faulty 27 MHz output
(frequency, waveform) from 27-1OUT (3 pin) of PLL (IC102) is
doubtful.

The power (EVER +3.3 V) is not supplied to the IF CON (IC404)
on the AI-24 board.
The X401 does not oscillate.

[POWER]

Any button has been pressed.
The voltage at PONCHK (e; pin) of the IF CON (IC404) on the
AI-24 board exceeds 0.5 V.

[POWER]

The PONCHK (e; pin) of the IF CON (IC404) on the AI-24 board
is abnormal (slow rising from 0.5 V to more than 1.5 V, or voltage
not rising to more than 1.5 V).
The SYSTEM CONTROL (IC103) on the MB-98 board is faulty.
