We are driving CFAG320240CX-TFH-T-TS using a pic microcontroller board. Initialization of display is done once, and after that data is continously written to display memory for viewing. During continous write to display memory display suddenly becomes blank showing a blue horizontal line. what are the possible reasons for this and how can we rectify it.

I would think there must be a problem with the power, or some noise problem.

What is the physical connection like (connector to PCB, cables, breadboard . . . )?
