Servo Futaba 9650.

One day I have a hard landing. But after quick jobbing I flew again with no problem. Next morning I see the 9650 is not initialized to its center position. It was on its band edge and produce a "bzzz" noise. I'm stupidly :oops: reinstall a horn and start flying. Everything was ok until 6-th minute when the tail start spinning. CRASH.
Now the 9650 would not initialize to its center position. I plug it directly to receiver (AR6100) and the servo rotates rotor clockwise to its band edge. As a result it reacts on stick input in one direction only.
Is it possible to solve the problem? What's happened to the servo?

PS: other servo (3154) is initialized correctly (I've checked).

Sounds like the 9650 is bad. I would think something is wrong on the PC board inside the servo or the pot has gone bad.
