green purple tint on composite input

[ironwoodVideo]

We just did our first job on our new Tricaster Studio of taping our high school fashion show. We had a three camera set-up using bnc cables connected to the composite inputs.
We did a test in the class room and everything was working fine. When we moved the set-up into the auditorium input 1 had a green purple tint to it in the preview and live window. Switching the cable to the other composite inputs produced normal colors so it wasn't the camera or the cable. Any suggestions on why this would happen? Do we have a bad input?
I'm going to try a component connection when I get to school tomorrow.
Thanks.

A couple of possibilities, in hopes it's not a hardware issue. The connection type for Input 1 in Input Setup may have been incorrect, Or someone may have accidentally set up improper Proc Amp settings for it (also in Input Setup).

To add to the weirdness the component imput works on input one. I also tried the six camera mode and all the composite inputs worked except for the third input. One worked on the six camera.
I don't see a proc amp setting in the input section where would that be?

I've circled the relevant bits ...

Thanks. Here's a screen shot of what it looks like.

Well, that's pretty psychedelic. The only suggestion I can offer (apart from taking to Tech Support) is to try calibrating the input ... you'll see the drop-down menu at right.

I don't know what is causing the psychedelic banding, but the monitor images not aligning properly indicates your monitor is not at the correct resolution of 1280x1024.
