I think my SVS cylinder sub just blew up! (1 Viewer)

[TonyD]

ok i've had it for about 3-4 years so i'm not even sure which one it is.
i think its a 20-39 PCi.

anyway we're moving stuff around and someone turns it off and unplugs both cables and moves it across the room.

now plugging it back in all i get is loud buzzing.

the fuse is intact.

i'm sure it's cooked.
i guess i'll have to get in touch with svs but shoot.
now i dont have a sub for who knows how long.


:frowning:

Maybe the cable got jarred loose at the receiver end?

Mort (who would really miss his SVS tube too)

 

[Guy Usher]

Sounds just like your interconnect cable is loose. Check your sub/receiver connection. Or a bad cable. . .

 

[John S]

I agree, sounds more like a bad cable / connector.


Does it happen with no cable attached? If so, then bye bye sub. :frowning:

 

[Cees Alons]

"Sounds" more like a bad ground connection somewhere. Could be the sub indeed, but very likely somewhere else too.

[TonyD]

thanks for the ideas.

i've unplugged it checked the interconnect on both ends. the fuse is good.

when the connect isin and i turn on the power to the sub nothing but heavy buzzing.
so it's either the sub or the output from the denon.

i'll be dropping a note to svs to see what my options are.


the subs have a 3 year warranty i think but i'm sure its longer then 3 years.

Tony - try another cable.

 

[mylan]

I have to agree with PaulT on this, try another cable. I shipped my Velodyne all the way back to California thinking it was the sub. They couldn't duplicate the problem but I did get an amp upgrade out of it. Once home the problem returned and I did something I should have done first, I replaced the cable, coulda saved myself $300.

 

[TonyD]

did it.
still heavy humm/buzz.

i'll be getting in touch with svs.

 

[TonyD]

well tom at svs has already decided to send me a new amp to install.

what a great company.

 

[Parker Clack]

Hmm...almost sounds like a grouding problem too. Is the power cable that you have your receiver a three prong or two prong job? I know when I put my Replay TV into the loop with my preamp my sub started to humm like crazy. It wasn't until I took the Replay out of the loop that the humming went away.

While you are waiting on the new amp try just plugging in say your DVD player alone into your receiver and then plug in the sub to your receiver and see if you still have the humm. Or try plugging the sub into another outlet from where it is now and see if you still have the humm. A humm have usually found is related to a ground issue. Since you moved the receiver and sub to a new location in the room it may be where you have the two of them plugged in now.

Just something else to try while waiting.

And yes, I agree. Tom and Ron run one great company.

i have it plugged into the some place as before, i just moved the sub to the otherside of the room.

its plugged into an outlet strip with a circuit breaker on it,
the strip is plugged into a grounded outlet in the wall.
same as before.

i even plugged it into the back of the denon to see if it would be different.

 

[Cees Alons]

Bad signal ground can also be caused by a corrupted/ill connected cable or a damaged connector.

Whatever the cause, the problem will soon get solved, now you're receiving a new amp. Great service by SVS, BTW!

[Chris PC]

Could be that an output transformer on the amp is gone.

 

[TonyD]

i received the replacement plate today and that did the trick.
thanks tom.

i can watch movies again!!

 

[Cees Alons]

Congrats, Tony. And kudos to SVS!

Tony:

Great to hear that you will no longer have to go through bass withdrawal.

I swear every business out there should have the kind of customer service that SV Subwoofers has.

 

[DavidRD]

Stories like this one has certainly made my future subwoofer choice easy. SV subwoofers all the way. What a great gesture to send you a new amp.

 

[TonyD]

although i cant remember if i had the sub for more then 3 years they said i was still under warranty which happens to be 3 years.
