i must say that it looks like they took a good hit!
more like some one plugged it direclty into the wall or connected
backwards.
  i think you those are HexFet transistors use to supply a
high amout of current with low engery drive..
  normally what i do in a case like you have there
is replace all of them with the same lot component..
  meaning, just buy all of the same part number.
because i have found that even though another
near by in the same circuit may appear to test
ok it maybe possible they are not./.
  heavy current surging on non formed contacts generate
a flyback effect which in turn is high voltage and can
damage other units since we are talking about power fets.
