I'd check vox settings. My backup radio, a  ts-450 did the exact same thing 
when I first got it and come to find out the  previous owner turned vox gain 
all the way down and antivox all the way up. We found that at field day. I 
just thought vox  didn't work until then, when someone tried cw, I figured 
out pretty quick it was settings and fixed it.
