Remove all power sources for at least 2 minutes. That means removing the batteries and power cord completely from the K board. Then try again. If that doesn't do it, it'll be time for a service visit...accordianman

This may be a hard one to analyze, however my educated guess is that a static discharge is putting the internal processor in a program loop it shouldn't be in.
It is my experience that you MAY not even feel a discharge even.
Suggest you make sure to not wear static producing clothing as a test. Sliding across a piano bench might even create the discharge.
The unit SHOULD not be sensitive to this, but the designers don't always do things right.
ALSO make sure the unit is plugged into a grounded receptacle.
Use of external things like amps and headphones can WORSEN the problem of static. External amps MUST be fed from the same receptacle.

If you have a 12v power cord going to it i would try giving it a gentle wiggle. If you find a sweet spot and the keyboard stays on then you have a broken solder joint on the 12v input.

Not sure if your "booklet" is the full user manual... if not go to this site and go through their "hoops" and download the full user manual. It shows how to put the unit in the mode that merely lights the keys and plays the rhythm, unlike the "demo" mode.
Note the manual is free via the Retrevo site... just have some of those annoying hoopps like email address and entering numbers.
