    Hi,
    The cause can be anything relating to that IC.  Something that causes excessive heat is generally a shorted condition that allows excessive current to heat up the IC. Of course, it could be one of the components very near the IC and not the Ic at all.  Can you see on the other side of the board where the discoloration is; search for a burned or discolored resistor or some component.

    My suspicion is the solution will require an expert tech to take some measurements to track down the guilty parts. There are too many possibilities for long-distance analysis.
