The ROM version, region code, OPT type, etc. are displayed if

[5]

 is selected in the Test Mode Menu. The parenthesized

hexadecimal number in the version number field indicates the
checksum value of the ROM.

Note : After down loading ROM data, sometimes it happens that

checksum is not the same as that of ROM data which has
been down loaded. In such a case, go back to the menu
and select “0. Syscon Diagnosis”, then select “1. All” in
“2. Version”. If the result of this operation does not give
an agreement, it must be either Down Load error or ROM
error.

On the Test Mode Menu screen, selecting 

[6]

 displays color bars

for video level adjustment. During display of color bars, OSD
disappears but the menu screen will be restored if pressing any
key.

When any button except 

[POWER]

 of the main unit is pressed in

the Test mode, the unit exits from the Self Check mode of the
fluorescent display tube.
While a button is pressed, the function name of that button is
displayed on the FLD, and when stops pressing the button,
“Nothing” is displayed. When two buttons are pressed
simultaneously, “DOUBLE” is displayed. As for the name of the
button refer to the following table.
For the button with LED, whenever it presses, turning on the light
and turning off are repeated.

The direction buttons on the remote commander are functioned as
buttons to entering the specific mode.

 :

Fluorescent display Grid check

 :

LED check (Not used)

 :

All lights up

 :

Fluorescent display Anode check

All buttons are judged with the voltage of A/D port. The reference
voltage of A/D port is EVER +3.3 V. To reject chattering,
measure the voltage twice and the same values are obtained, this
voltage is judged as the A/D port voltage. The dead zone is
provided for the IF CON button judgment voltage. When a
voltage within the range of dead zone is input, “IGNORE” is
displayed.

If the unit is received a command of the remote commander when
“NOTHING” is displayed, the function name of the code of the
remote commander is displayed on the display. The code which
the unit can receive is only DVD category.
The 

[DISPLAY]

 button on the remote commander functions as

switch of the button name display and code display. In the code
display mode, “REM NO.xx” is displayed. The received code is
displayed with hexadecimal notation into the “xx” column. When
the unit has not received the command, “FF” is displayed.

The IF CON and SYSTEM CONTROL are usually performing
both-directions communication in a cycle of 24 ms. This mode
checks in simple whether this communication is performed
normally. When “NOTHING” is displayed and the character
portion of 

[VCR]

, 

[DVD]

 and 

[CD]

 has gone out on the left side

of the display, this state means that communication with
SYSTEM CONTROL is performed normally. If the character
portion is lit up, this state means the communication is not
performed correctly. After the test mode is executed (until
initialization of the MB-89 board is completed), communication
is not performed for several seconds. Although the character
portion may light up in these intervals, but this is normal.

Fluorescent display tube lighting check can also be performed
roughly by automatic mode. But when checking in detail, use this
mode.
When 

[STOP]

 and 

[PLAY]

 buttons are pressed simultaneously,

all segments of the fluorescent display are turned on. The 
button of the remote commander can also turn on all segments.

This check mode makes it turn on one grid of the arbitrary grids
of fluorescent display at a time. (All anodes of applicable grid are
turned on.) During this check mode, grid of one somewhere
surely lights up. The 

[CLICK SHUTTLE]

 of remote commander

is used for movement of grid. However, since there is no

[CLICK SHUTTLE]

 in remote commander of supplied accessory,

it can correspond by the remote commander for DVD with

[CLICK SHUTTLE]

.

This check mode makes it turn on one anode of the arbitrary
anodes of fluorescent display at a time. (Applicable anodes of all
grids are turned on.) If 

[CLICK SHUTTLE]

 is rotated clockwise,

the check will begin from P1 and will move with P2, P3 .... After
the check of the last anode finishes, it returns to P1. During this
check mode, one anode in all grids surely lights up.
The 

[CLICK SHUTTLE]

 of remote commander is used for

movement of anode. However, since there is no

[CLICK SHUTTLE]

 in remote commander of supplied accessory,

it can correspond by the remote commander for DVD with

[CLICK SHUTTLE]

.

Whenever 

[EJECT]

 button is pressed, SUROUND LED (D406)

repeats on and off.

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.

1

Red LED does not light when AC is supplied (standby)
The power (EVER +5 V) is not supplied.
The X401 does not oscillate.
FTC connecting between FL-123 and MB-99 boards is
faulty.

2

At 

[POWER]

 button ON, LED is kept in red (standby state)

Any button has been pressed.
The voltage at PONCHK (30 pin) of the IF CON exceeds 0.1
V.

3

At 

[POWER]

 button ON, LED lights in green but returns to

red (standby state) after several seconds
The PONCHK (30 pin) of the IF CON is abnormal (slow
rising from 0.1 V to more than 1.5 V, or voltage not rising to
more than 1.5 V).
The SYSTEM CONTROL is faulty.
