Sabertooth 2x10 motorcontroller

Hi,

I am using a sabertooth 2x10 motor controller in my tank style robot. I have been controllong it with a PIC microcontroller board and all has been going well. Until the other day when i was using it and the status1 LED went off and the board stopped working. When i power it up now, all the motor outputs are at 13V and the status1 LED stays off. I have taken the heat sinks off the board and inspected the components but all looks ok.

In desperate need of help.Does anyone have experience of this problem? All help greatly appreciated!
