Remarks
Symptoms: DVI signals are not recognized.
Causes: This fault occurs when the PC does not

the DVI DDC has not been input 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.

TN panel and is displayed when no
video signals are supplied.

occurs on the screen.
