Hello fellow members,

i have a Klipsch power sub-woofer model R-10SW and it has stop working after a power outage.  it still turn on and the sub still have sound but it's like baby sound compare to what it was before the power outage. Currently I disconnect the sub from the two board and is using it without the board "so the sub is still good".  Im hoping you guys would point me into the right direction of how to diagnose it and perhaps repair it.  the sub have 2 board and i've attached images of both board.  Thank you for your time, god bless.
