Just a total guess here but if it has relays you might look for a short to ground in the relay operating path.
Had it happen to me once on an Old Tempo One. I guess you could also check to see if any of the relays are stuck in the Xmit mode even without power.

This may sound simplistic but you might want to check the VOX switch

Sounds like the T/R relay is stuck.  Must be something simple simple like that. If the transmit light is on and the receiver is muted, then the T/R relay is probably the culprit.  If I remember correctly, the T/R relay is near the back of the rig somewhere.  I think it may require some dis-assembly to access the relay.  You might want to post that question on the Kenwood relector for some more ideas, and/or some more specific instructions.

GL and 73,

Is the "SEND/REC" Button, located extreme right center of the rig, above the PHONES jack, pressed in?

Just a thought.. been there done that...
