Help minelab explorer xs

[nautilus-dmc2]

I have a problem with my Explorer XS came off a component, which I can not find someone can tell me what component of treatment? I think a diode or transistor.
5902-0009 where is the card that you connect the battery and speaker
Many thank's
I add a second picture with higher resolution

missing

did you take this off, or was it never there

the component is broken out and it is impossible to read the letters, thanks for the interest, I hope to find someone who can tell me what was this part thanks

it is a surface mount transistor you could get away with an equivelant if you find out its pin configuration my guess is if its audio output npn type but best to be on the safe side i have an xs if you need the correct details for it.

Unfortunately in my XS have been deleted the names of the components of the 3 pin one (the one below) is connected to the negative batt. Across from the central 2 resistors and a capacitor goes to an IC (initials removed) and the higher card connector goes to central. I believe that only someone who has this metal detecetor can help me.
Sorry for my English. And thanks again to all
