Condition : When condensation has formed inside the unit
Results : As soon as condensation is detected, the unit will shut down.
Possible cause other than condensation
• Disconnection of CN2002 between the condensation sensor and the
Y DRIVE Assy
3 Condensation detection
Shutdown temperature of each temperature sensor
TEMP2 data 150 ( 80°C)
TEMP3 data 117 ( 64°C)
As for the TEMP 1 sensor, a shutdown occurs when a disconnection
of connectors is detected, but does not occur because of temperature.
Temperature displayed in "INFORMATION" of the Factory menu
TEMP1 (°C) TEMP1 (data) -50
TEMP2 (°C) TEMP2 (data) /2+5
TEMP3 (°C) TEMP3 (data) /2+5
Reference
1 Panel microcomputer failure
2 DIGITAL-IIC communication failure
4 Abnormally high temperature
Shutdown diagnosis
Condition : When the module microcomputer failed in communication
with the 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 the 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 assemblies.
• Breaking of wire between the following point:
DIGITAL VIDEO Assy (D1) ↔ SW POWER SUPPLY Module (P2).
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.
Possible causes if this abnormality occurs in an
environment in which the temperature is not so high
• Disconnection between the SP TERMINA (L) Assy (SPL1) and
MX AUDIO Assy (A3).
• Disconnection between the MX AUDIO Assy (A5) and RGB Assy (R8).
• Disconnection between the DIGITAL VIDEO Assy (D18) and
temperature sensor 1 (TE1).
