I hope there are some electronics experts that could help me on this and I apologize for it being not directly arcade related. I have a Klipsch SW-450 subwoofer that has stopped working. Cosmetically it is in pristine condition. The problem seems to come from the plate amp. When I plug it into a power outlet it makes a faint rapid clicking sound. The funny part is this noise occurs no matter what state I have the sub in (On, Off, Auto). So even when set to off it happens as soon as the unit is plugged in. I immediately assumed it was a power relay. I tried the official Klipsch support but since it is a couple of years old they are asking a price that is just shy of buying a new sub. I pulled the plate amp off and looked at the circuit board. I see no darkened areas and no capacitors that appear to be swollen or broken.
I am attaching a photo of the circuit board. My hope is that someone in the western Chicago suburbs that has the electronic skills to diagnose and determine if it is worth fixing or not. I'd hate to throw it away because other than this the thing is perfect. If it is possible to fix the relay or power transformer or whatever the problem may be for 50 bucks or less I would greatly appreciate it.
I have a video that shows the sound but I don't know how to upload that.
