I have a little problem.. One of my speakers stoped working. First it came a weak "humming" sound and then a much powerfull one. After this I cant turn on the amplifirer on the speaker. I was thinking the fuse was broken, so I deasembled the amlpfirer from the speaker and when I did this (cerfully) a capasitor fall out. I could see where it came from, it was a dark spot on the printboard. Info on the capasitor: 47 micro F/200V - brand: Licon. I dont anderstand this, I have not mishandled or played loud whit the speakers
