Hello,

I was listening to music and suddenly it stopped, and since then I can't get anything from my speaker because it doesn't even turn on when I plug it in, nor when I press the power button!!! Can anyone tell me what's going on? Thanks in advance for your help ????
Configuration: Android / Chrome 77.0.3865.73

    I simply know, thanks to the downloadable service manual here:
    https://elektrotanya.com/sony_mhc-v11_ver1.2_sm.pdf/download.html#dl
    that there is a fuse on the "PSU board" located at the power socket.
    It is a 6.3A fuse.
    Excerpt from pages 40 and 41
    To replace it, the device must be opened.
    But if it is the fuse that has blown, there is a strong chance that this is due to a more serious problem in the internal circuits.
    Very difficult to catch a black cat in a dark room.
    Especially when it isn't there...
