4.	As necessary, adjust the input audio level of each input (see “Viewing and
	adjusting the input audio level (HVA models)”, in this chapter) so that the
	approximate output level is the same for all selected inputs.

Troubleshooting

This section gives recommendations on what to do if you have problems operating the switcher, and it describes an actual image problem that Extron has encountered.

General checks

1.	Ensure that all devices are plugged in and powered on. The switcher is
	receiving power if the Esc LED flashes one time when you push the Esc
	button.
2.	Ensure an active input is selected for output on the switcher.
3.	Ensure that the proper signal format is supplied.
4.	Check the cabling and make corrections as necessary.
5.	Call the Extron S3 Sales & Technical Support Hotline if necessary.

Plasma display S-video problem

Extron has encountered a problem when a matrix switcher with two or more video planes routes S-video that is output by some video conference codecs. Some codecs change the DC offset on the chrominance (C) so that it is very different from the level on the luminance (Y). This can cause a plasma display to come up in the wrong size mode.

With the matrix switcher taken out of the system, the plasma works fine. It looks like a problem with the matrix switcher, but it is not. The matrix switcher boosts the bad codec output, which makes the plasma go to the wrong setting.

Solution: Try placing an Extron video DC block adapter, part #26-495-02, on the luminance (Y) input to the switcher from the codec.
