    your report says it needs repairing, i allready know this, you were to come up with a possible solution.

  • brendand1944 Nov 29, 2008

    still no help can you be more exact, since i see many other reports with the same problem, i assumed you would be able to pin point this problem more accurate.

    I think this solution makes more sense, thank you.

There is a condensor (capicator) in the sub woofer that has to be replaced, the buzzing you hear is displaced eletricity. Open it up and look gor the largest capicator thats the one at fault. Be careful though its a bad shock if you handle it bad please be well inuslated. No its not high enough to cause damages just a bit of pain.

Sorry to tell you the ciruit is fried even if the machine you have even is on just a little like a clock and is not connected to a surge protector lighting can go directly to your electronic and do what has happened to you and that is fry your circuit I suggest if warrenty still is good take back for replacement or repair/ or just buy a new one.. but for future reference use a surge protector and here is a neat article that tells you why you should use one.

http://www.howstuffworks.com/surge-protector.htm


What this should be used for is your "computer,tv, or any other expensive electronics

I would just look at 1/4/5 those seem most important.

    Like I sayed you FRYED your circuit because you left it plugged/in on
    during a storm while it was not connected to a surge protector so
    specifically the high amount of voltage went to the circuit zapped the capacitor... Lighting voltage goes up to like 1 billion and your radios only goes up to maybe about 100V so it ruined it by over charging it.. I'll post more if you want

"loud buzzing starts for a short while and slowly fades" one of the capacitor on the amplifier final section, or preamp had blown and you get a 50 or 60 HZ loud humm that slowly fades as the AMP ICs stabilizes the signal.

Try first the following:

Test a different socket, just in case the socket has lost ground after the power surge.

If that does not work call the service number listed on the owner manual and ask modalities to fix the unit, it should have one year factory warranty on it.

    check your spaker in direct ly with computer or any dvdvcd plasyer.

    if it works fine then no pro in speker.

    also check in woofer then check all connection of cable soldering again if need.

Why is there a loud humming/buzzing coming from speakers?


most of the time this is caused by a bad ground. Check all cabling from and to the right side satellite and the sub woofer.

Thunder storms can cause control boards to go erratic. Try unplugging the refrigerator for a minute or two and after plugging it back in hopefully the problem will go away.

What source(s)? Verify the speaker setup with the test tones to prove the hardware is all okay. Then go back and evaluate the conditions that create the problem. It could be an external cause.

Subwoofer problem


If you get your system up and running and hear an audible buzz or hum, the first culprit to look at is either the powered subwoofer or your reciever feed at the entry point to your system.

If the amp produces no boom with no signal input cables connected, I'd suggest using an LOC.

Loud Buzz upon starting


sounds like just a vibration caused by cols hitting the frame perhaps, sometimes a pull from underneath the unit on the condenser coils will rectify the problem(id give a pretty quick tug, . unit could just be settling into the floor or the house settling around it, vibrations are definitely annoying but usually no need for alarm

Static Interference With Subs


First test would be to disconnect the RCAs from the amp and see if the buzzing goes away. If it does, the issue is either with the head unit or noise still being picked up on the RCA cables. If the issue stays, it's possible your electrical system has not a nice and clean 12V. You might have to get your alternator and voltage regulator (if so equipped) checked.

Also, make sure the RCAs on the back of the head unit aren't touching anything metal. Set your gain to 50% and see if the buzzing changes. Check your ground connection and make sure it's short, clean, and solid. If you have multiple amps, ground them to the same point.

The circuit that should be turning the sub on and off based upon the presence of an audio signal is not working correctly and the sub is trying to reproduce 60 cycle hum. The unit needs service.
