Troubleshooting (continued)
No image appears on the screen. (Continued)
Problem | Solution |
"NO SIGNAL" is | • Turn on the power of the connected device, or check whether there is something |
displayed. | wrong with the connected device. |
| • Check whether the external device outputs signals. (Check this especially when the |
| external device is a notebook computer.) |
| • Check that the cable connected to the external device isn't defective. |
| • Check that the projector is connected to the external device using the correct |
| terminals. |
| • Check that the connected device is correctly selected as the input source. |
| • When an extension cord is being used, replace it with the supplied cable and check |
| whether images are projected correctly. If images are projected correctly, use an |
| RGB signal amplifier along with the extension cord. |
