    Those could be anything. I don't suspect they function in normal operation. They could be simply reverse protection or TVSS diodes designed to take very momentary surges, Likely TVSS and a P6KExxx could be used of appropriate voltage.  It looks like a lightning strike so those are the least of your problems.  Before proceeding, check the four FET by measuring the resistance of the two outside pins of the three.  Any resistance under 100 ohms indicates they are bad.
