    BB 9000 has developed a problem with the click switch located under the trackball.
    Essentially this is no more than a dome shaped piece of metal which goes slightly flat when compressed thus making contact on the pcb.
    The problem is that this now inverts when pressed and does not go back to its original dome shape so carrying out switch functions is not possible.
    Replacing the trackball pcb is not an option, even though I have had numerous years of experience in electronics, my soldering does not extend to the equivalent of micro-surgery.
    Has anyone else had this problem? If so, what was the solution?

    Thank you

    i used to clean the one on my 8330 w/ a q-tip & rubbing alcohol,,, maybe that'll loosen up the gunk that may be in there...

    I penciled my dome till it popped back to shape, forced the pencil on the underside of the dome and tried pressing it on a flat surface, making sure it stays its shape.

    If you have damaged the yellow tape that holds the dome in place, scotch tape, cut to shape, is a quick fix.

    Otherwise cnn.cn sells replacements.
