Subwoofer goes to sleep

Hi, I have a new Cerwin-Vega VE-28S powered subwoofer. When I turn it on the LED light turns green and it works fine. However, after few minutes the light turns red and there is no sound coming out of the sub. If I turn it off and on the same thing happens. What am I doing wrong? By the way, I have Onkyo TXSR505 receiver. Thanks for helping. dadara

    I wonder if it can be related to the receiver setup, but I doubt it...

It is not getting a strong enough signal.... when you have the sub setting on the receiver to low the sub likes to go into sleep mode..... try turning the sub signal up on the receiver and the sub amp down to get the desired level.

The receiver automatic speaker set-up set the sub volume at -12 and since it was not getting any signals from the receiver it was doing what it is supposed to be doing (going to the standby mode). This was troubleshooted by Onkyo tech support on a Sunday. All the best about Onkyo customer support.

I have a cerwin vega ve 28s sub and noticed static sound coming out even when no music was playing. The next day sub went into standby in the middle of a song. If I turn it off for a couple hours it works...


First, disconnect it and let it run with no input. Problem here is that it probably has an auto-turnoff and will shut off. My bet is that either your connection wiring is faulty and/or your amp is sending down either RF or DC signals. I would get it close to the amp with another connection cable and check... Good Luck !

When turning on the power on my cerwin vega 15" sub the protect light which is a built in protection on the amplifier keeps coming on the power on light does not come on at all just the protect light


The sub could be shorted or the wire connections of the sub could be shorted, or there could be an internal problem with the amplifier such as a shorted output stage or failure of some other component(s)

Cerwin vega avs sub8. no power. changed blown fuse and still nothing. no power light indicator. unless led light bulb blew which i believe to be unlikely it has no power. any ideas


I got the same problem, my sub was working perfectly and suddenly one day it did't turned on, so I think it is the protection from the internal transformer, it needs to be changed but I don't know the model, if someone else knows I would appreciate the info because it is a really good subwoofer for the size...

Hello. My ve 28s crackles when in standby mode, and also plays crackly bass. Please help me by telling me which component to replace within the amp. as I have no Cerwin Vega agent support here in South...


Hi,
This "Crackling" Problem is common with the Cerwin Vega VE-28S Subwoofer. If your subwoofer is out of warranty, and you know how to solder, you can fix the problem by replacing a few resistors, and transistors inside the amplifier. Get the parts on ebay: http://cgi.ebay.com/250756306868/

Cerwin-Vega 12'', no power


It should have a small fuse on the board between the transformer and the board. Check that first. If it is good see if the transformer is putting out any voltage. Two easy fixes that can be done in house...

Crackles and pops,even in standby mode


Does it only pop and crack when its connected to your amp or receiver ? i have the same thing with my sub [its not cerwin vega] but when i turn my amp off the sub doesnt pop anymore so i think my amp is the problem not the sub , yours might be the same problem .

Cerwin Vega ve-28s subwoofer and new Cervin Vega 2-way satellites


I bought my VE-28s and it did exactly that crackled, cerwin replaced part in amp but few months later problem persisted. they then replaced entire amp assembly and its been fine. i really push it to and its been fine. to test it, unplug the connection from amp/ reciever and see if it persists. if so its the sub, if not its the amp/ reciever. dont dump it, these subs really crank and can put out some deep loud bass.
