I have Marshall Acton II column, it does not give anything, not even sound,
without the leds. I've already disassembled it and I've been checking,
it has 18V at the output of the power supply that connects the main board.
From the main board connect the board whrw have power button and sound control, bass, trelbe ....!
and on that board there should be a voltage of 3.3 V at a point that comes from the main board and there isn't...
I've tried to see voltages on the main board. The BT module turns on because I can detect it with the phone and turn
it on but there is no sound (nor the LEDs on the top plate, as I said)
Does anyone have any help? any schematics for this column? I'm desperate ...
