    Might be an oscillator/crystal. Not sure.
    What makes you think this component is defect?

    Agree with Harald, most likely an oscillator module I see a couple of capacitors hanging off pins

    Improbable. This kind of oscillator usually doesn't overheat.

    Harald erred on that one, they are powered, so hence they can fail and cook
    that looks pretty obvious from your pic :)

    Looks ok to me...

    Looks cracked. Doesn't necessarily mean its bad, could just be the package but its definitely suspect.
    I looked a little but did not run across any sot23-6's with code of AJ8. If you find out what it is make sure to let us know !

    First picture looks perfectly fine. Second picture looks off but if its same board as the first picture then seems to just be lighting imo.

    *shrug* I think its the same board with different lighting and angle.
    Only TS could really tell us I guess.

    I don't know what it is, but it looks more like AJX to me. ajx.jpg

    I checked X first (both with no good results) The smaller image I looked at seemed like it had some faint curves so I was leaning to 8 but this larger blown up one you are providing looks more like an X to me as well now.

    Hello,

    There is only one in the housing you have.
    The others have other housing or a small x.
