Shut down diagnosis
1 Panel microcomputer NG
When a module microcomputer failed in communication with a panel
microcomputer, this NG occurs.
Shut down after OSD display for 30 seconds from the NG detection.
Abnormality to expect
Open / Short of communication line in the Assy
2 DIGITAL-IIC communication NG
When a module microcomputer failed in communication with outside
EEPROM or EXPANDER, this NG occurs.
Shut down after OSD display for 30 seconds from the NG detection.
* However, this communication NG may occur in the standby state.
Abnormality to expect
• Open / Short of communication line in the DIGITAL VIDEO, MR INTERFACE
and AUDIO Assys
• Check 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
3 Dew detection
When it becomes the dew state in this unit, this NG occurs.
After the dew detection, shuts down immediately.
Abnormality to expect for dew drop
Disconnect a connector CN2002 between Dew drop sensor and Y DRIVE Assy.
4 Temperature abnormality
When temperature of this unit is abnormally high, this NG occurs.
Shut down after OSD display from the NG detection for 30 seconds.
Note: When temperature fell down during indication, return to the normal operation.
Abnormality to expect when it occurs in the environment that is not
high-temperature
• Disconnect a connector between DIGITAL VIDEO Assy (D18) and
temperature sensor 1 (TE1).
