what's up with my motor???

[indie]

i have a parallax standard servo that is controlled by PIC
16F84A. the problem is why does my servo can't move untill
it's max position (180 degree) only 140 degree eventought
i've gave 2-2.4 ms pulse (for max position) to it ??? please help me ?? if
the problem comes from my servo, could you tell what is
the possible thing that cause the problem ??
thank's

There is a mechanical stop in all servos. Trying to go past the mechanical stop will damage the gears with time. Perhaps your servo is not designed for 180 DEG rotation.

i'm sure that my servo is designed for 180 deg rotation, just like parallax said in their website .... any idea ??
