Fault Photo Symptoms and Corrective Actions Remarks
Symptoms: DVI signals are not recognized.
Causes: This fault occurs when the PC does not
recognize the mode information because
the DVI DDC has not been input to the
monitor.
Corrective Actions: Input the DVI DDC to the monitor.
* Refer to the Training Manual for
information on inputting the DVI DDC.
Symptoms: When the monitor is turned on,
only a full white pattern is displayed
continually regardless of the signals.
Causes: This fault occurs when only the lamp
power is supplied and no video signals are
input to the panel due to a fault or incorrect
connections of the LVDS cable.
Corrective Actions: Replace or reconnect the LVDS
cable correctly so that video
signals can be supplied to the
panel.
* A full white pattern is a feature of the
TN panel and is displayed when no
video signals are supplied.
