    Logitech THX Z-2300 Computer Speakers and Subwoofer. I've had them for several years. I was playing music and smelled burning coming from the woofer through the port hole. I unplugged it all left it alone for a while. A few weeks later I checked the fuse (.4A/125v) and noticed it was blown. I tried a new fuse and it blew right away. I've bought a couple new fuses and each gets blown right away. The control pod will not power up anymore. I just noticed that one of the prongs on the back got bent off when we moved not sure if that is causing the control pod not to power up. The control pod wouldn't power up before the prong was bent either. Help! Can't see myself getting rid of these they are awesome and I've had them for a long time. 1627_2430.jpg 0610205179-colunas-logitech-z-2300-thx-200-watts-rms.jpg

    The broken prong is the top right one. The burning smell and the blowing fuses happened before this got broken.

    undo that clamp bar across the devices screwed to the heatsink and tell us what those devices are

    you may find that one or more of them has a puncture hole in the front of them

    do a sharp close up pic of the transformer
    and also of those 2 devices in the yellow sealer below those 2 big capacitors

    which fuse was blowing ? ( that is ... where is the fuse located that was blowing ?)

    And show us closeups of both sides of the board in the area of the D-15 connector you want to replace.
