Key the mic on CW as well, it will work. that seems strange though if it 
showed high power before. Hopefully there's nothing going wrong. If you have 
the tuner in the radio on, turn that off and see if that changes things. I 
haven't checked on the TS-2000 yet but I know my 570, the tuner can cut the 
power back a bit. Not that much, but it's something to check anyway.
