Hello all,
New to the forum and happy I found it!
I'm attempting to repair a noise coming from the wireless subwoofer in my Klipsch SB3 soundbar. I posted a video of the squeal and then oscillating rumble. It doesn't start when powering up, it starts after the soundbar and subwoofer connect wirelessly.
Initially I suspected the issue was capacitors on the subwoofer's internal power supply or amp but I didn't find anything obvious. I disassembled the soundbar and found a bulging 470uF 25V cap on the circuit board with burnt glue that obviously needs to be replaced.
I believe it's part of the amplifier's output since there are two of them and the soundbar's speaker connections are pretty close (On the left), but I'm not certain. I'm only hoping this will fix the subwoofer noise but the wireless module for the subwoofer (On the right) is on the other end.
I have a capacitor with the same rating but as you can see in the photo it's much smaller and the skin is a different colour. (Capacitor in photo is not bulging but was also in burnt glue so I'll replace it, too)
My question, does the replacement need to be physically identical or is it safe to use the one I have with the same values?
Thanks for reading!
