Your message leaves as many questions as it asks.  Typically though unless 
you're familiar with electronic design and troubleshooting there is little 
difference between "not working due to burnout" and "not working."

These modules have a two year warranty from Digium; why not call their 
technical support centre and get the module replaced?  It's very likely under 
warranty and therefore the time spent trying to diagnose it is more or less a 
waste; just replace it and let their warranty department handle the why.

If you feel that the module received a surge or other transient, why not 
attach a surge suppressor and/or telephone line conditioning and protection 
equipment to the line?  I'd recommend that for any equipment connected to 
copper leaving the building.
