I have no idea how the PCB got this effect.

    Yea, looks like over-volting damage. Maybe the voltage regulator failed. Just my guess

      That’s what I thought. Maybe due to voltage spike in the house. But it is definitely strange. Never seen something like this since I started studying/working with electronics for the past 8 years.
