Question about Jamo E6SUB Subwoofer
I have power to the sub however it doesn't activate or turn on when the stereo is running. Before the sub stopped working I would have to turn the volume on my receiver higher with each use in order to 'trigger' it so it turns on. Seems to be stuck in "sleep mode".... The speaker's voice coil is not blown as I take speaker wire from one of my surround speakers go directly to the woofer and sound comes through sub.
is the plate amp fried?
More likely there is a bad solder connection or a bad connector contact inside the unit, could also be a blown or dried up electrolytic capacitor.
Check the line signal input plugs, if they are soldered directly to the board then check the solder around the pins - if it has circular cracks, you need to resolder the pins.
Also check any other components on the board for such cracks on the pins, including internal connectors, disconnect, clean the pins if necessary and reconnect them.
If any electrolytic capacitors have a bulged top, they are blown and need to be replaced.
It could as well be something else, but your description suggests either a fault at the input connectors or some trouble with the input signal level sensing circuitry (no signal to the sensing circuit may be caused by connectors, no response from the sensing circuit may be caused by bad capacitors or other faulty components in or around that section).
Hope you can find out what it is and fix it...
