Dsw 660wi

I have had 2 dsw 660 subs in my basement theatre since 2011. I moved out due to a major renovation on the upper floor in March. I moved back in a month ago and both my subs seems to have issues. Can’t get any sound from them through LFe, remote seems unresponsive.

I suppose I need a new controller board for both of them. Ironically, both subs have the same issue.

Does anyone know if there’s a separate controller board available, or I have to change the whole amp circuit board?

I suspect some power issues during the renovation fried my equipment.

    Does anything light up?

    One of them gets the green power light on the back and the LED on the front when I turn it on, then the power light goes from green to red. Same thing happens when I put it in either “on” or “standby”

    The other gets no LED on the front, and power light on back goes red immediately.

    I pulled them apart and found C14 on both of them blown. On the first on, there is a component B1 ... looks like a barrel tube battery (thought it should be labelled BT1)...it has one of its legs melted...not sure if that component is fried too...or it is just collateral damage from the cap.

    I am tempted to get some new caps and if I can identify the B1, then get a new one of those as well and try to fix it.

    I’ll post a picture of the boards.

    Both boards have capacity cooked but one has the B1 component leg melted away.
