The most common failure would of one or more of the output MOSFETs.  With the power disconnected and the unit opened up, check the MOSFETs with a diode checker looking for shorts.  I suspect that you will find one or more outputs to be shorted.  Change both for whatever channel is bad.

Let us know what you find.
