Subwoofer turns on but no sound

[Jack5296]

So I got a pretty old Megaworks 510D That was working perfectly and then i unplugged it by accident and now it makes no sound but the light turns on with it like normal, I've looked inside it and everything seem'd ok I think. I Have very little if not no knowledge about subs but I have some knowledge of electronics in general though. Any help would be appreciated.

Check all your plugs it sounds like you hooked something up wrong. As a tech it's easy to miss the obvious stuff, but it's normally the obvious stuff.

Thats what ive been doing all day and the thing is i had it working perfectly fine then it just suddenly stoped working after I unplugged by accident while it was in us. Ive tried just letting it sit unplugged for awhile also but to no avail still.

And all the speakers attached through the sub work? Am I right that this is the system found here http://download.cambridgesoundworks.com/manuals/megaworks510d.pdf ? If all your speakers are working and going through the sub, I'm at a loss.

Maybe the amplifier went into protection mode, but it really sounds strange to me. I don't envy you.
