Disklavier

Having a slight problem here with sticking keys.  Manual playing of 
the piano is ok, no keys stick.  However when the DK is playing 
several keys stick as soon as they are played and one key will not 
play at all.

Anybody have any ideas or suggestions. (I know, call the tech)

Sounds like a drive board problem.  Have the note numbers and the piano serial number ready when you call your tech so he can order the correct drive boards from us.
