That is really unfortunate. I hear that in order to obtain a board you need to purchase unreal amounts, just like manufacturers. Perhaps you can email one of the vendors that do icepower modules like Red Dragon Audio or even Henry Ho at H2O audio... Henry seems to be a nice guy who might be willing to hwak you a board....that blown component is really miniaturized...no doubt machine soldered.
2 years of running it...to me it seems as if it is a defective component or something, not too common, or so I hope. I also have a Icepower module based amp in my mom's place, an S250 by H2O audio.
