Servo Trouble

I just got a RN-1 and everything works great, except for one thing, the knee joint on the right leg. When I make him go into the sitting position, that leg doesn't collapse fully, making him lopsided. This also happens in any program where his legs are collapsed. And when I turn him off, I can move it fully.
The servo horns are right, and so are the zero settings. Is there anything that can be fixed, or should I request a replacement?

Any help would be greatly appreciated!

EDIT: I have solved the previous problem by reloading the template program, but now I have another prolem. The servo won't respond to the set zero point program. Whenever it is activated, the servo goes limp and is unresponsive. Triggering this proram also unchecks the checkbox in both servo control programs, and even whe it is re checked, the problem persists in all 3 programs. Any fixes, or is my servo broken?

Hi
question
1 is the servo hard to move when the bot is powered?
2 just as a test have you tried the servo in another channel?

1. No, it's stiff and works perfectly except for the last 10 degrees.
2. No, but I will

Also, it seemed to work fine on roboremocon pc control, so i'll try that again

Try loosening the four long screws that hold on the bottom plate of the servo. If they are too tight they can bind the gears. If that doesn't work open the servo and inspect the gears. Maybe one of the teeth broke off and wedged itself on one of the other gears.
