Page 30 When an electrical field is applied to the LC planes, the LC molecules re-align themselves so that they are parallel to the electrical field. This electrical process is known as twisted nematic field effect or TNFE. In this alignment, polarized light is not twisted as it passes through the LC material (see Diagram 3A and 3B).
Page 31: Simple Troubleshooting
Simple Troubleshooting If the display fails or the performance changes dramatically, check the Display in accordance with the following instructions. Remember to check the peripherals to pinpoint the source of the failure. Symptom Solution Power cannot be turned -Check that both ends of the power cable are on.(Power indicator plugged into the socket appropriately and the wall does not light.)
