|
| turn the lamp on. Check LAMP STATUS. | ||

| |

|
| correct source is selected. |

| |
| 2. | The horizontal or vertical scan frequency of the input signal may be out of range | ||
|
| for the projector. Refer to Section 6, Specifications for scan frequency ranges. | ||
| 3. | The sync signal may be inadequate. Correct the source problem. |
