    I just recently got my MiBox 4k. Everything works fine, except there's this faint, but clearly audible electric sound coming from inside of the device. Kind of sounds like a hiss from a bad usb charger.

    This is annoying when everything else at night in the room is quiet but I can clearly hear the box working (even in "standby" mode).

    I would imagine this device shouldn't be making any noises due to lack of moving parts, just like with the mobile phones.

    So is this normal or did I get a faulty unit? Thanks in advance guys.

    Are you using the original transformer shipped by the factory?

    The recent MiBoxes require a somewhat elevated power input of 5.2V/2.1A whee generic power supplies only give 5.0V/2.0A.

    BTW, what is the exact model number on the label on bottom of your STB?
    There are 4 models that can be described as 4k.

    My model is mdz 16-ab. I'm using the original power cable supplied with the device.
