    Hello from France,


    Sorry for my poor English, but I need your help.

    My MK head doesn't work anymore.

    I've read a lot of threads ( french forum) about issue related to this brand.

    I've send a very gentle e-mail to MK ( What can I do, is there an official and authorized reparator in my area, can I buy replacement pièces ?).... no answer ( I've sent my e-mail since 3 weeks,), other customers are in the same situation ( They tried to contact mk Customer services wihtout result) .

    Finaly, A friend've opened the head, the power supply still works but the head doesn't "works " ( blue led still off). The fuse was changed too.

    It's not easy, so he request me the schematics.
    Of course the head is out of warranty.

    Thanks' in adavance for your help and my apologises for my English.

    Kind Regards.

    Sébastien

    Good luck getting the schematic. Markbass is extremely guarded about stuff like that.
