TS-2000 - CW Keying Malfunction

Unfortunately the CW keying in my TS-2000 is not working. The presets for the auto-keyer work fine for some reason, but I can't get either paddles or a straight key to work.

I had this happen at the start of Field Day (of all times/places), but powering up the rig a few times got it working for whatever reason. I didn't have a problem with it since (until today).

If any of you have a TS-2000, or know of someone that does, who has experienced and fixed similar symptoms let me know! I really want to get this resolved.

I did post on the TS-2000 yahoo group also. I will post updates to the prognosis if I hear anything through the group.
