Troubleshooting
This section gives recommendations on what to do if you have problems operating the switcher and describes an actual image problem that Extron has encountered.
1. | Ensure that all devices are plugged in and powered on. The switcher is |
| receiving power if one of the front panel I/O LEDs is lit. |
2. | Check to see if one or more outputs are muted. |
3. | Ensure an active input is selected for output on the switcher. |
4. | Ensure that the proper signal format is supplied. |
5. | Check the cabling and make corrections as necessary. |
6. | Call the Extron S3 Sales & Technical Support Hotline if necessary. |
Configuration Worksheets
Rather than trying to remember the configuration for each preset, use worksheets to record this information. Make copies of the blank worksheet on page
Worksheet example 1: System equipment
Figure 3-59 shows a worksheet for an MVX 128 A in a fictional organization with the system hardware annotated. Inputs 10 and 11 have no connection in this organization, so they have been crossed out on the worksheet.

Figure 3-59 — Worksheet example 1: System equipment
Inputs include PCs, an audio CD player, cameras, and an Extron VTG 300. Output devices include monitors, front and rear projectors, a stereo, and a VCR for recording presentations.
The VTG 300 video test generator connected to input 12 enables a video test pattern to be sent to one, several, or all output devices for problem isolation or adjustment purposes. An audio test tape or CD could be used in a similar manner to check out the audio components.
