In my case, it was the AUX connector that went bad, after I had tried many other ways.
Now, looking back ,it seems that this soundsticks.2’ capacitors were actually good. Mine has been used for more that 10 yeas. The top of capacitors looks good. But still, before i could find out the problem with AUX connectors, I had already replaced quite a few capacitors. Hope this speakers could work for another long period.
My subwoofer no longer worked. It was the capacitor problem, the 25v47uf one that near the power button. I replaced it, and everything goes well.
Again, the glu that holds the mini speakers was not in good quality. I re-applied some and fixed it. Guess it was a common problem.
My soundsticks.2 was made in China, Suzhou. The capacitors were green ones, other than black ones. The brand was ftom or something. It’s good.
