Bruce, I had the same symptoms. In my case it was caused by a broken solder connection where the power jack attaches to the CP board. I removed the CP board, heated the connection and added solder to it. The problem is solved.
The power jack is a surface mount device and as such had very little solder where it is connected to the board. If I were to build another KX3 kit I would resolder the power jack connections before assembly as a routine precaution. This appears to be a weak point in the KX3 construction.
