Oh crap!



I started up Serenity today only to notice that I was getting absolutely nothing from the sub. Lo and behold, I check the back of it and it doesn't seem to be powered on at all! The little light that is either red or green doesn't turn on at all.


Could it be that the electronics or the amp has died in this thing? I haven't used it all that often and it's only a little over 2 years old.....which means the electronics might be out of warranty.


What should I do? My system sounds lifeless without it...does HSU let you buy replacement parts if need be?

Did you double check all your cables? Did you check the fuse?

I did double check my cables. I don't know where the fuse is on it though....I'm guessing that's not the volt switch? Where would the fuse be?


edit: I found the fuse, I can turn it and it pops out, but when I put it back in and plug everything in, I still get no power. It looks like it's still good too, the little metal wire in it doesn't look like there's anything wrong with it.

Well, it's been unplugged for more than an hour and I just tried it...nothing



I've had it for all this time and have not once opened it up...are these things supposed to be cleaned out (dust?) every once in a while, or are they fine without that?


The sub worked fine a week ago, and has been unplugged since then. I had just barely plugged it in today when it died - I wasn't playing anything loud on it or anything. It was completely cool too.

Hsu is supposed to have great customer service. I would contact them and post the problem on the forums on the Hsu site. Pete is always on there answering questions.

I contacted them and they already emailed me telling me that I could send it in and get it repaired/replaced...it's out of warranty so it'll be $80-$120 plus shipping, but that's better than having a dead sub!


It would be nice if it was something obvious and easily fixable...I have very basic electronics and soldering experience...I doubt though that I'd be able to see what the problem is.

It seems strange the sub was not working when it had been unplugged. I hate to ask but are you certain the power cable is secure on the back of the sub?

Just for giggles, try plugging the sub on a seperate outlet all together and see if that works. Sounds crazy but I had my laptop stop charging from the bottom connection of the same outlet. I thought something was wrong with the laptop but accidentally pulled it, plugged it into into the top section of the outlet and worked fine. Try moving it to another outlet and see if anything changes.

Should I worry about shock hazards when taking the amplifier section out?

First rule of troubleshooting: Make sure it's plugged in


Yeah, it's secure as I can get it...I've tried more than one power cable, making sure it was firmly pushed in, tried jiggling it a little to see if I get any response...


I don't know. It was working for a few seconds after I plugged it in and turned it on, before it died yesterday. Something must've went wrong in that time, maybe?


@Bunga99: I've tried it plugged into a surge protector (everything else that is plugged into it is working) and I've tried the other connection on the same outlet. I guess I could try a whole other outlet altogether, but I'm not exactly hopeful of it working

I would see if Hsu is willing to let you just send the amp in for service and save on shipping.

Yeah, they told me to disconnect the amp from the rest of the sub and just send that. Thank God...I'd much rather pay for shipping for the amp than for the whole sub

Well, I'm shipping it off to HSU in California today to get it looked at. So far the customer service has been great. One of their techs called me personally and talked to me about it.


I'll cross my fingers - hopefully my sub won't be absent from my setup for too long!

Let us know what the diagnosis is. I just ordered one earlier today.

They told me that it didn't show any signs of abuse or anything, but they replaced a couple components, including a chip. I got it back yesterday and it works just fine again.


Also, I don't think I gave the correct age of the sub earlier in this thread - it turns out it's just over 3 years old.

So wait, you took the fuse out and put the same fuse back in? If the fuse is bad then it still won't work by popping it out and putting it back in. I've seen bad fuses where that little metal wire looks perfectly good. I would have tried a new fuse? I don't know, I've never replaced a sub fuse before but I assume it's something you can get from ratshack? Yikes, if so, they may have just replaced a $3 fuse.

He did say the fuse looked fine. If it was a bad fuse it would be easy to see it was bad.
