The front board test mode is the IF CON self diagnostic mode.
The IF CON can diagnose the functions of the front panel boards
that the IF CON controls. Normally, the IF CON makes a serial
communication with the SYSTEM CONTROL and operates fol-
lowing the commands from the SYSTEM CONTROL, but in the
Test mode, the IF CON operates independently from the SYS-
TEM 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

6. LED control function

In the Test mode, the set operates same as usual, except voltage
monitoring, communication monitoring, display of fluorescent
display tube, and LED control.
1. The routine that monitors +3.3 V (P-CONT) of MB-103 board

is not provided.

2. The monitoring timer for serial communication with the SYS-

TEM CONTROL is not provided. The set is not placed in the
Standby mode, even if the communication with SYSTEM
CONTROL is normal.

3. Display of fluorescent display tube (normally, display is made

following the commands from SYSTEM CONTROL)

4. LED control (normally, control is made following the com-

mands from SYSTEM CONTROL)

The Self Check mode is the function to conduct the basic test to
the FL display and DVD panel section.

At the AC Power ON after IF CON (IC404) was reset, the input to
10pin (SELF CHECK) is judged and if “Low” is entered, the main
unit transits to the Self Check mode. In this port input judgment,
the result of 3-time attempts must be same (assuming that the MB-
103 and AV-63 boards are not connected). While pressing the

x

key

on the main unit with the IF CON in STANDBY mode, enter

[      RETURN]

 

→ 

[DISPLAY]

 (or 

[SET UP]

) on the remote com-

mander, and the unit transits to the Self Check Mode. The Self
Check mode terminates when the IF CON transits to the STANDBY
mode.

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 dis-
appears but the menu screen will be restored if pressing any key.

When the Self Check mode becomes active at the AC Power ON
or by key input, the test display of the following steps (1) to (4) is
repeated.
(1) FLD and LED all ON (for 5 seconds)

(2) MODEL display (for 2 seconds)

(3) Version display (for 2 seconds)

(4) ROM creation date display (for 2 seconds)
