Propeller Servo Controller: Noisy Output

I am trying to control six Hitec servo motors (for actuating a delta robot and some other equipment) using the propeller servo controller and I am facing two major problems:
1. All of the 16 servo control ports are not working (luckily for me, I have found six that do work). By "not working" I mean that either the commands sent from Matlab to these ports do not lead to any motion in the motors (but the motors do maintain an equilibrium position) or the motors are not even able to maintain an equilibrium position and fly about wildly.
2. Even the six functional ports have a really noisy output. Initially, when the power is switched on, one has to manually hold the servo horns so that there is no damage to the delta robot's links. This is before the first control command is sent from matlab. After that things stabilize a bit, but now and then the servo motors still show random vibrations.
I don't know if it's a fault with the particular piece I bought or noisy power supply (I am using an Aplab regulated DC power supply providing 5.6V and 10A max. current) or something else. Any help would be deeply appreciated.
