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

As for the TEMP 1 sensor, a shutdown occurs when a disconnection
of connectors is detected, but does not occur because of temperature.

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).
