Section 4: Maintenance and Troubleshooting

Symptom ' The display is jittery or unstable…

CAUSE/REMEDY:

1. If the display is jittery, or if it disappears and reappears erratically check that the source is properly connected and that its signal is of adequate quality for detection. For example, if the projector scans the default input for a signal to display, and poor quality or a source is improperly connected, the projector briefly and repeatedly attempts to display an image. If no source is connected, the “no signal” error message appears over a blank display. Correct the source connection.
