Troubleshooting
Turn on the input devices (DVD, DSS, cable box) and output device(s) (VCRs, monitors, projectors). The image should now appear on the screen.
1. | Ensure that all devices are plugged in. |
2. | Make sure that each device is receiving power. The TSC’s |
| front panel LEDs light if the device is receiving power and |
| an active sync signal. |
3. | Check the cabling and grounding, and make adjustments |
| as needed. |
4. To ensure correct cabling from the TSC to the display device, turn on the Color Bars output, using an SIS command, and disconnect the input signal.
5.Check that the appropriate output standard is selected.
6. | To test the system setup and output, substitute a video test |
| generator (VTG) for one of the video inputs. To use a |
| VTG, unplug the input and output devices and the TSC’s |
| power cord, replace the video source with a VTG, then |
| reconnect power cord to restore AC power. |
7. | Call the Extron S3 Sales & Technical Support Hotline if |
| needed. |
