I'm not an EE, (changed to CS after two semesters..) but as I recall, 
this is likely a transformer and also a possible indicator of shortened 
life.

I wouldn't take anything to CompUSA, for repairs, but I understand your 
issue if that's all you've got to work with.  These days, not many folks 
repair monitors, and I doubt CompUSA will have anyone on hand to give 
you a reasonable solution (outside of replacement).  Most of these type 
of folks know little (if anything) about electronics.  Then know how to 
swap cards out, install software and the like.
