I can't help (though someone may be able to since you did not provide very much in details. Since this is your very first post welcome! Hopefully you are in the USA and can get a hold of Barry Green's book. There are so many details discussed in his book which may be able to answer your questions. For instance how were you shooting? What scene files, aperture, frame rate, shutter speed, light sources, distances. Tungsten is not green so that question in itself is problematic. If you had not white balanced, the might have been just that. I know I had a green tinge when I did not WB and I had mixed light sources. Recognize if you are shooting in AI (fully automatic) you introduce yourself to a Pandora's box of issues and I am not sure if anyone could help you when you do that (because there are so many things that can go wrong with AI).
 
I found this green tint on skin in the shadows as well. Using B.Press gamma fixed it for me. There are a couple of other gamma settings that are ok too, but I can't remember them off the top of my head. I tested the various gamma settings by hooking the camera up to my pc monitor and flicking between them while holding my arm in front of the lens. I was usings flouro lighting when I found this issue. I hope this helps!

I would have just switched matrix to FLOU, but I've not tested that yet either.
 
thankx guys I'm in bakersfield Ca manually record everything i working for another company and use only sony pmw ex1. so buy this camera to record my own events for the price the first video did not give me that green tone but not played much with the camera and in the latter event had that problem and would not be playing with the settings during the event i remember it was scene 1 default manual focus manual iris 1080 1920 30 p shutter speed 60 led light on top im so sad :cry:
 
I just changed the gamma to b. press and really helped remove that green skin tone I would have liked to know this in my last event

Is the LED your main light? If you both had better luck with B Press gamma I need to check that out for myself. I have a 312 bi-color LED and I didn't like the way skin tones looked no matter how I dialed the temperature (or changed the settings). I felt there was just something wrong and I could not put my finger on it. Though my main felling is there just was not the reds you see with tungsten.
 
It's probably too late but have you tried color correcting your already shot footage? You'd be surprised. In Premiere Pro for example, all it might take is the the "Color Balance RGB" effect and then lower eighter the Blue or Green a bit and theen increase the Red a little. Another thing you could do is use a white balance effect. If it's completely bad, it'll be a little hard to color correct but you never know if what you have can easily be fixed.
