Screen display
Condition : When a module microcomputer failed in communication
with a panel microcomputer
Results
: An OSD is displayed for 30 seconds after the failure is
detected; then the power is shut down.
Possible causes
• Open/short-circuit of the communication lines in the assembly
Condition : When a module microcomputer failed in communication with
an external EEPROM or EXPANDER
Results
: An OSD is displayed for 30 seconds after the failure is
detected; then the power is shut down.
Note: A DIGITAL-IIC communication failure may occur in Standby mode.
Possible causes
• Open / Short-circuit of communication line in the DIGITAL VIDEO, MR
INTERFACE and AUDIO Assys
• Breaking of wire between the following points:
DIGITAL VIDEO Assy (D1)
↔
SW POWER SUPPLY Module (P2)
DIGITAL VIDEO Assy (D3)
↔
MR INTERFACE Assy (R3)
MR INTERFACE Assy (R23)
↔
AUDIO Assy (A24)
System Cable
Condition : when the internal temperature of the unit becomes abnormally high
Results
: An OSD is displayed for 30 seconds after the failure is detected;
then the power is shut down.
Note: If the internal temperature of the unit becomes lower while the OSD is
displayed, the unit returns to normal operation.
Possible causes if this abnormality occurs in an environment in
which the temperature is not so high
Disconnection between the DIGITAL VIDEO Assy (D18) and temperature
sensor 1 (TE1)
