Question about Logitech Z-2300 Computer Speakers

1 Answer

Speaker buzzing at random

I have had my Z2300 speakers for a few months, recently though I have been getting a loud buzzing noise at random. I can fix it by moving the audio cable at the back of my computer around. I have wireless but have had it from the beginning and my speakers worked fine.

    Tancks for the speedy reply Bob, but I have many audio port at the back of my computer and have change them around constantly unfortunatly the same buzzing occurs...

    I have not checked the however, but the buzzing can happen a few minutes after I start using my computer or a few hours, it's really wierd

    Thanks for the info I think it is the PSU, and the fact that I am running a lot of appliences off just the one power socket.

    I just had it buzzing then and I plugged in my laptop charger and it stopped instantly. I'll switch out power boards and see how things go.

    Thanks again

It sounds like the socket on your computer is becoming worn or has a loose solder joint.

If you feel comfortable with a fine tipped soldering iron and stripping your computer down I would take a look there first.

Also check the power supply for the speakers to make sure it is not getting too hot.

    Thanks for the extra info. I would still look

    at the PSU for the speakers.



    If you have an older power bar for the computer try swap that out too.



    Have seen an "arcing" on an older bar that cause fine flickersing on a monitor which may translate to noise in your case.



    Also try to see if its the same time each day or coincides with an air con unit or other appliance powering up, older fridges can also have a noise factor.



    If it is an appliance it may be a heads up to get it checked.

Klh powered subwoofer model ASW10-120B... when you plug in to power... it makes a loud buzzing/humming noise


I would check the caps on the power supply. They are rather large electrolytic capacitors that will look like they burst and/or leaking. When these die, the caps ground and the sub will make a loud buzzing sound. If you are handy with a soldering iron you can replace them yourself. Replace them with the same voltage or a little bigger and same with the size.

If the cap. says 16v 4700pF on it, for example, a 20v 5300pF or a 16v 6200mF cap. will work for this application.

I have a 4 month old Dell Studio 1535 laptop, with audio problems


Hi,
Firstly check that the microphone level is down or turned off as this sounds like some sort of feedback that's being produced.

Check the microphone and try to play music again.

Please post back


Good luck.

The noise is a hum or buzz. We've narrowed it


Hello,

By chance have you tried making sure the laptop is not too close to the speakers? Sometime you will get feedback when the source is to close to high powered speakers. Also, check your jack cord and make sure no splits/cuts are visiable and the plugs are fully inserted.

Good Luck and keep making great music. Aloha.

Buzzing/humming noise that increases as you raise volume. So loud that you can not even watch tv


Hello snow1525,

You may have a torn speaker element. This is usually the cause of buzzing noise in the sound, also you may have a bad capacitor in your audio section. This is what I would suggest doing as a test open the front bottom panel of your TV and visually inspect the speakers for signs of ripping and or tearing in the speaker element. If the element or elements are torn it may be possible to repair it with rubber cement or rubber paste just coat the tear with the rubber cement to hole the torn edges together and allow it to dry for two days before testing the sound. If the speaker elements are not ripped then the problem may be a bad capacitor either in the audio section (power supply) or in the filter block (usually attached to the speakers to separate bass and treble signal to the speakers.

I hope this helps,

Thank you,

This is common in these type speakers but usually comes from poor grounding in the computer or in your outlet.
connect the unit to another outlet and run from a walkman or some portable player and see if you get the same buz. Work backwords from there by plugging into the same plug and unpluggin everything else. You will probabbly find something in/around your outlet is causing the noise.

Distortion/noise and buzz in front left speaker


Try to see if the reciever will make the buzzing/noise without anything connected to it except power, and speakers. Tune into a local radio station and see if the noise continues. If the noise has stopped, then you know there is an issue with the player or cable.

Loud and strange noises


The built-in speaker amp or the volume switch may be going bad on you. A quick test is to disconnect the speaker set and replace it with a headphone or another working speaker set. If it behaves normally then the problem is in your original speakers, if not then you may have software driver issues or less likely an issue with the sound card. Let us know what you find out.
