    Harman/Kardon Onyx II Bluetooth Speaker

    I have this speaker that won't turn on.
    The BC57E687C Bluetooth chip gets warm after about 1 minute with the wall charger connected.
    I hope you can help me please.

    I attached a very similar schematic.

    Mi altavoz tiene micrófono incorporado y entrada auxiliar. El diagrama del altavoz en el esquema no.

      Dell Harman Kardon Dead Left Speaker
      by dorfman
      Working on an early 2000s dell / harman kardon computer speakers.

      Suddenly only the right speaker works. No sound is coming out of the left. Also, the right is much louder than when both speakers were working. The minimum volume setting sounds much louder than where I previously set it (half way). And the loudness difference between minimum and maximum position on the knob is small compared to when both were working.

      I checked the signal wire for continuity from the board to the jack. Both channels and the ground are continuous with low resistance and not shorted...

      Would I be able to swap a 0.27 Ohm Kx2 5W resistor for a 0.22 Ohm Jx2 5W resistor in a Harman/Kardon AVR? Cement type.

      Harman/Kardon AVR 645 returning to stand-by after a few seconds.
      by PowellSkier
      A Harman/Kardon AVR 645 repair has been a hobby of mine for the past several years. My latest attempt involved the purchase of a DOA unit for part swapping and testing. The original AVR would power up then shut down after a few seconds. I completely tore down both units, found a couple of bad components and reassembled one of them. Same issue, no speakers connected. After extensive research I found a repair document from Harman/Kardon that explains the protection circuit in fantastic detail and provides specific test points for each fault (power, DC detection, overload & power) and the voltage...
