Condition : Fan failure
Results
: An OSD is displayed for 30 seconds after the failure is
detected; then the power is shut down.
Note: Fan failure is detected only in the following cases:
• When the FAN CONTROL is set to MAX
• When the FAN CONTROL is set to AUTO, and the temperature
at the TEMP3 sensor is 30
°
C or higher
(Fan failure is not detected while the fan is not activated even if
connectors become disconnected.)
Possible causes
• Disconnection of a junction connector between FAN (A6) and the
MX AUDIO Assy (A7).
• Disconnection of a connector between the MX AUDIO Assy (A5)
and the RGB Assy (R8).
• Forced stop of the fan caused by a foreign object being caught in the fan.
5
FAN failure
Condition : When the main microcomputer has failed in communication
with the module microcomputer
Results
: An OSD is displayed for 30 seconds after the failure is
detected; then the power is shut down.
Note: A module microcomputer communication failure may occur in
Standby mode.
Possible causes
• Open / Short-circuit of communication line in the Assy.
• Disconnection of a connector between the RGB Assy (R3) and the
DIGITAL VIDEO Assy (D3).
• Writing defectiveness of module microcomputer (IC1207) software.
6
Module microcomputer failure
Condition : When the main microcomputer failed in communication
with the wide 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 communication line in the Assy.
• Writing defectiveness of the wide-microcomputer (IC5601) software.
• Writing defectiveness of the external Flash ROM (IC5602) of the
wide-microcomputer.
7
Wide microcomputer failure
Condition : When the main microcomputer failed in IIC communication
Results
: An OSD is displayed for 30 seconds after the failure is
detected; then the power is shut down.
Note: An RGB-IIC communication failure may occur in Standby mode.
Possible causes
• Open / Short-circuit of communication line in the Assy.
• Incomplete insertion of a SLOT or a SLOT junction PC board
8
RGB-IIC communication failure
Condition : When a DC component is added on the speaker output line
Results
: The power is shut down as soon as a failure is detected.
Possible causes
• Disconnection of a connector between the MX AUDIO Assy (A5) and
the RGB Assy (R8).
• Short-circuiting b and - of C8615 and C8622.
9
Audio failure
Note:
In a case of incomplete insertion of a SLOT, the following
symptoms may occur in addition to the above results.
• Audio signals to INPUT 3 and INPUT 4 are not output.
• Switching to INPUTs 3-5 (SLOT function) is impossible.
• Video signals to INPUT 1 and INPUT 2 are not displayed.
