    This is an old Nikon 3.3 Mega Pixels camera, the model is Cool PIX 990.
    It has be a good camera for a number of years.

    Recently, someone decided to put a 12 VDC (instead of 6 VDC) for the
    power input and the camera stop working.

    The question is what is the likely damage has occurred to the camera?

    Any suggestion is high appreciated.

    someone = absent-minded u? :)
    If not, consider it a hard lesson to never ever let anyone else touch your
    gear.
    Could be many different things... blown caps and/or resistors, blown IC
    protectors, blown IC's, etc etc..
    Unless you're very very lucky and the only damage is perfectly obvious and
    simple to both get at and to correct, this won't be cheap to have repaired
    by a pro.

    I repair these things and have seen this happen before. Sometimes
    there's a fuse inline to the power input and yes have seen expoded
    caps, regulator chips etc.
    Usually the cheapest bet is to find an appropriate parts camera (one
    with a working power board) on eBay and swap the power board.
