I have a Brymen TBM859CF multimeter. It works on all functions except on AC volt

    The above mentioned multimeter for some reason is unable to display AC voltage or AC amperage. It operates on all of the other
    DC functions extremely well including temperature and capacitance.

    I have checked the 4 main diodes on the input section which appear to be all ok. I do not have a circuit diagram and so am unable
    to proceed any further. I am hoping that this is a simple problem which I am unable to spot and was hoping that maybe someone else
    on the forum has had a similar problem and could point me in the right direction. Any help would be greatly appreciated.

    Many thanks,

    Cliffd
