Troubleshooting

Identifying the Left and Right Polarizers: Although the left and right polarizers have
very different optical characteristics, they appear to be identical. As a result, once you
remove them from the projector it may be difficult to tell them apart. Use the following
technique to verify which one is which:
1. Place the polarizer on a clean, smooth, flat surface with the side that faces the
projector facing up.
2. Hold a pair of 3D glasses above the polarizer as shown here:

3. If the right lens on the glasses turns black when it is above the polarizer, this tells you
that the polarizer came from the left-eye optical engine on the projector.
Table 5-1 provides some general guidelines for troubleshooting problems you may
encounter with the D-73d Series LED 3-D Home Theater Projection System. If the
suggested solutions fail to resolve the problem or if you encounter an issue not
described here, please contact your Runco dealer or Runco Technical Support.
