    I have the exact same bad components. I noticed this burnt through-hole just behind the IC. Do you know what this is used for? There is nothing on the other side. Could it be and internal layer that has burned at this point? I don't suppose anyone knows where this goes so I can jumper it.

    Well from the looks of it after putting light behind it, it doesn't go anywhere. There are no other layers other than the top and bottom. I guess it could be arcing from one of the pins and jumping to the ground of that via.
