    It looks like it's that same, like mosfet Q77 right in the upper left corner, next to the mounting hole on that same side of pcb. Its really hard to read something from it. For me it looks like there are used some other symbols as a markings, not only letters and digits. Check yourself, but for sure two last letters are "GY".

    Unfortunately I don't have camera with macro to make the picture of actual element, but like I said it's that same like Q77. Markings on chip looks for me like this: mosfer markings.gif .
