My home theater system stopped working?

Question

I have a Philips 5.1 home theater system that has a built in DVD player. On the back of the receiver, there are no audio outs, but a "monitor cable" looking plug. That cable goes to the subwoofer where all the speakers connect. Now, for the past few months, when powering up, the speakers used to make a crackling noise like a speaker "engine" was revving up. Once it was 'revved', they would turn off. I would press "mute, mute" and they would work. Now they finally got exhausted. The system doesn't work anymore. I noticed the fan on the back of the subwoofer no longer blows. This means that the sub doesn't work, so the speakers can't work. Is there any way to check this out? I don't think it's blown, cause that would have made the speakers go out quick, not slowly die after a couple of months.

Answer 1

ether that or due to the malfunction of the fan the system automatically gives you the message and turns it self off to prevent damage to the rest of the components such as built in DVD player

Answer 2

sounds like its a powered subwoofer, could be a blown fuse or the amp itself is blown. my amp went on my powered sub and i had it fixed at a small electronics repair shop for $50 parts and labor
