Hi:

A computer monitor stopped working and had that smell.  After getting it apart 
enough to have a look found this circular component cracked almost into two 
parts and the PCB is charred on one leg.  It's at the line input section of the 
mains power supply right next to a bridge rectifier and large filter cap.  On 
the pcb below the part is what looks like a schematic symbol in the form of a 
"Z".  Photo at:   http://www.prc68.com/I/HaT.shtml#CM

What is it?  Do they fail, or is it likely something down stream is shorted?
