12TROUBLESHOOTING
NOTES
1.Please note that if the output signal is disturbed or interrupted by very strong external electromagnetic interference, it should return and stabilize when such interference ends. If not, turn the power switch off and on again to reset the machine.
2.If the recommended actions still do not result in satisfactory operation, please consult your CVG Dealer.
12.1Power and Indicators
Problem | Remedy | |
|
|
|
No power | 1. | Confirm that the rocker switch is in the “ON” position, and that the lamp is |
|
| illuminated. |
| 2. | Confirm that power connections are secured at the machine and at the |
|
| receptacle. Make sure the receptacle is active, outputting the proper mains |
|
| voltage. |
| 3. | If there is still no power, check the fuse. Remove power cord from the AC |
|
| outlet and from the machine and then, using a flat screwdriver, remove the |
|
| fuse holder located directly below the power connector. Confirm that the fuse |
|
| is good by looking at the wire connected to the ends of the fuse. If the wire is |
|
| broken, replace the fuse. |

12.2Video Signal
Problem | Remedy | |
|
|
|
No video at the output | 1. | Confirm that your sources and output device are powered on and connected |
device, regardless of input |
| properly. Video signals connected to the input of your machine should be of an |
selected. |
| identical signal format at the output of your source. Video signals at the output |
|
| of your machine should be of an identical signal format as at the input of your |
|
| display or recorder. |
| 2. | Confirm that any other switchers in the signal path have the proper input |
|
| and/or output selected. |
| 3. | Use the Video Tester to test the video path leading to/from your Matrix |
|
| Switcher (see section 4.1 " Video Tester") |
|
|
|
Video level is too high or | 1. | Verify that the video line is well matched through 75ohm impedance, |
too dim. |
| otherwise it results in a video level that is too high or too dim when looping is |
|
| performed and the termination switches are not in proper position. |
| 2. | Confirm that the connecting cables are of high quality, properly built and |
|
| terminated with 75ohm BNC connectors. Check level controls located on your |
|
| source input device or output display or recorder. |
