GR1400LT - Why does the display on a GR14XXLT Master Panel Remain Blank or Only Partially Active After it has been Reconnected?

On a GR1400LT series Master Panel, the display screen may be blank or only partially active if it is disconnected from the control card then reconnected while the panel is powered up. This is NOT a defect. The display screen may not reset or re-synchronize after it has been reconnected as the synchronization is only performed during start-up of the master control card. The control card must be power cycled (turned off for minimum of 10 seconds, then on) before the display screen will resume its normal operation.
