Probably not going to be an easy fix if you are asking the question. They are the Mosfet power supply transistors. There is damage beyond what you can see. This is a list of things that you are going to have to at least check. The gate resistors, the surface mount devices just below the lower leg of the 2 transistors. (As Pictured) There are 2 surface mount transistors per transistor.
