Lansing AVS 500 Subwoofer loudly hums whether whether speakers are on or not

I have a Lansing AVS 500 system (several years old) and the subwoofer hums loudly whenever it is plugged in. The system is disconnected from the computer input and power to the speakers is off, but the subwoofer still hums as long as the converter is plugged into an outlet.

    The Subwoofer hums if the power is connected even if its turned off. The humming continues when the music is playing.

If you have a digital tester just select DC voltage then connect the positive leads of the digital tester to any of the wire coming out of the 18V adapter (WARNING do not connect to the wire connected to the main) and then the other lead of the digital tester which is the negative connected to the other wire of the 18V adaptor. If in the screen of the digital adapter reads a negative value, then it indicates that the other wire is the negative and the other is positive. Otherwise if the tester reads a positive value then your tester's leads have got the right connection.

SOURCE: Speaker popping when computer is on or off.

I have the same issue. Speakers were working fine then the sub-woofer just starts err...pulsing/popping/ The speaker cone is actually moving and it's like it's in a kind of loop. Powering off kills it for a while, but then it comes back making the whole speaker system unusable.

Mic is on, but no boost.
Not coming through all speakers, just the sub-woofer.

These were a good set of speakers, seems a shame to have to junk them.

SOURCE: I have Altec Lansing AVS 300 multimedia speakers with no power

Unfortunately the subwoofer supplies the power to the amp on the speakers, Once again I have the solution,
These speakers are factory molded so that the only way to open them is to break the factory seal
this can be done by sharply rapping the seam at the bottom of the speaker with a heavy screwdriver handle or something similar.
Now you need to supply power to the amp...If you do not have the subwoofer you will need a 4.5volt power supply, after removing the board from the casing find the red white and black wires connecting
the orange plug wire to it, Personally I removed the entire cord from the unit, shough you can splice in at this point if you desire.
Connect the white lead to your posative on your power supply by either splicing or soldering, connect the ground to the heat sink using the screw that is already there holding the chip to the sink. reassemble the speaker.....super glue... and you are now in business.

SOURCE: hoe to open avs 500 subwoofer

Hi,
The front cover is glued to the wood box.

You need to be very carefull with this job as there are risks of injury.

With a sturdy box cutter carefully make repeated passes with the tip of the (long) blade between the wood case and the front cover. It will only penetrate 3/16 to 1/4 in when finished. You will feel it when you reach plastic through the glue. When you are satisfied that all the glue between the side of the box and the cover is sliced, insert a flat tip screwdriver between the power cord and the wood frame to pry the cover off. Work slowly around the buttom so the marring in the plastic does not show too much. (yes you cannot avoid it) And be carefull that it does not shut closed on your fingers. Once you have some space opened you can use a flat blade to keep it open while you work around the other sides. A long flat tip screwdriver can be used to reach the opposite side to pry from the inside.
To remove the PCB from the front cover pry off the connector cover from the side of the front cover then pry that side away from the knobs to be able to lift the board straight out. It does not come our at an angle. Good luck and be carefull with the knife.
Bye

Subwoofer Emits a Buzzing Tone


The 2200 uF capacitor in the power supply has gone bad and the humming is a 60 Hz from the rectification of AC to 18 vDC.  Either get a new power supply or take apart the power supply and replace the bad cap.

I have altec lansing speakers AVS500 and have no sound


It sounds like the subwoofer speaker has blown. If you are comfortable working with a soldering iron and speakers then you can open the case and replace the speaker with a replacement subwoofer speaker. A good online store for replacement speakers is PartsExpress.com

Speaker popping when computer is on or off.


I use to get that same sound but only when I first booted up.
Is this only happening when you have the volume up and does it happen if you turn down the sound all the WAY not off
Your MIC could be enable and on boost level.
If you sound is popping from the music or other source is it from all the speakers???
I can try and help
