The FR-173 board (IF CON) test mode is the IF CON self diag-
nostic 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 following thecommands 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. Remocon 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 (PON CHK) of MB-94 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.

While pressing the 

[STOP]

 key on the main unit with the IF CON in

STANDBY mode, enter 

[RETURN]

 

→

 

[DISPLAY]

 (or 

[SET UP]

) on

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

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)

Contents of display
