Lost240 Posted August 1, 2016 Share Posted August 1, 2016 This weekend I just picked up a home theater package from the original owner. Unfortunately, when I got home I realized there was a rattling inside the SW-311 and it won't turn on. I took out the woofer and found a small circuit board. What is this? Can it be fixed? It doesn't look like it was ever attached to anything. Thanks! Quote Link to comment Share on other sites More sharing options...

CECAA850 Posted August 1, 2016 Share Posted August 1, 2016 It probably goes on the back of the plate amp. You'll need to remove it to see. Quote Link to comment Share on other sites More sharing options...
babadono Posted August 12, 2016 Share Posted August 12, 2016 We have a saying in the electronics industry "All parts DO something". If that part is in your sub disconnected, and your sub doesn't work, that's a darn good place to start troubleshooting. Does the board look damaged?
