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 thecommands 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. 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 (PCONT) of MB-86 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 was reset, the input to 8pin
(P60) 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-86 board is
not connected). 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.

• Keys on main unit except keys transited in self check

When a key on the main unit is pressed in the Self Check mode,
the name of that key is displayed on the FLD. Also, the key name
display and the key code display can be switched with the 

[DIS-

PLAY]

 key on the remote commander. “NOTHING” is displayed

when nothing is entered. Also, VIDEO CD, DVD, and CD seg-
ments turn on when a communication error occurred.
