Repair subwoofer Yamaha YST-SW320

[krneki10]

I have several years old subwoofer Yamaha YST-SW320 which started to slowly die this week. At first, it was playing sound just like it should with some noise here and there. This noise has became more and more often and there were also several silent breaks. As of moment we are speaking, it will play sound only for a few seconds per minute.

Is there any way that I could fix it? Perhaps replacing capacitors could work? Please notice that I have limited knowledge in electronics.

Thanks for help.

its probably not the subwoofer but the amp that is driving it
This could be any number of possible problems

The Yamaha site has two manuals. It seems you have to log on to download. I do not want to do this.
