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.

* 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.

full white pattern is a feature of the
TN panel and is displayed when no
