Static noise; no sound

Do you hear static noise when you turn the radio on or is it complete silence? If static noise, is there an antenna on the radio and is it getting proper signal strength?

Easy fix. No soldering. We have 4 of them. Did not want to fill the landfill. Found the noise coming from the power supply with a scope. Studied the Service Manual. Discovered that they use the exact same power supply in both sound bar and subwoofer. Swapped them. and thing work perfectly with no noise coming from the subwoofer that i can tell. Definitely no noise coming from the sound bar.
A bit more details: I connected my iPhone to the sound bar. Played Spotify with the volume turned all the way down. Static loud and clear on sound bar. On my sound bar, I discovered the static went away after about 15 minutes. I could see it go away with scope. Disconnect power for about 2 minutes and when reattached, static starts again. Static went away again after about 15 minutes.
Disconnect Power FIRST. Get your electric screwdriver and remove a bunch of screws including the screws on the connector panels. The power supply has a large yellow transformer and two silver heat sinks. AC power goes in one end and a single strip connector with a bunch of wires comes out the other. MAKE SURE POWER IS DISCONNECTED!!!! This could kill you if you miss this step. Remove the power supply.
Disconnect power on your subwoofer. Remove the 4 silver screws on the bottom of the subwoofer. There are about 4 black screws with little arrows holding the back panel in place. Remove those. You will only be able to slide the assembly out about 2 inches. Cut the white wire tie on the big foam covered wire. This is the speaker wire and once the wire tie is cut, you can remove the assembly about halfway. You will see a little coil of wire with three wire attached with another white wire tie. (Ferrite core just in case you wanted to know). Cut the wire tie and the entire assembly will come out. Remove the speaker and the three wires from the connectors and the whole assembly slides out.
Swap the power supply with the one from the sound bar. Put it all back together or test it if you want to insure this fixes it.
Enjoy!

That sounds like a bad connection but it can also indicate your mixer has a problem. If it occurs on all channels it is the mixer, if only one then the problem is in the input. Check your cables, they are a big culprut in problems like this.

clean the dust from your computer dust causes static which causes your computer to overheat and all sorts of problems
be sure to wear an anti static earth strap before touching anything inside your computer try cleaning your computer of dust using a fine air blower from a compressor making VERY sure that there is no MOISTURE in the air line specifically around the CPU central processing unit and your SOUND CARD dust causes static to build up in a computer causing it to overheat any many other problems
hope this helps

When you say static that they both work but one is noisy or are you saying that the only one is making a noise and nocoherent sounds coming from either

What sort of computer do you have? Is it a laptop or desktop? Many laptops have this problem and it is quite widespread in laptops. The crackling or humming noise could be a result of interference from the mains power signal.

If it's a laptop, try running it on battery alone (take out the mains power cord). My laptop has this kind of noise in speakers when running on mains electrical supply, but it goes away like magic when I run it on battery.

A more long-term solution is to buy a 'Ground Loop Isolator' and insert it between your computer and the speakers/earphones. They are quite cheap and you could get it for under £10. It removes all static noise and you'll hear crystal clear sound.

change youre speakers they are blown if they are making staticy sounds i have recently chnged my speaker cuz of the static and it was kuz they were blown

thats all i can think about
hope it works

The static is probably coming from the computer sound card itself. Turn the volume down on the computer mixer it should limit the static you are hearing.

Normal 0 Two things can cause static.
First, If you have your speakers turned up to high it will give you feedback causing distortion and static. I recommend using a headset when videoing.
Second reason is, if you are using a laptop and have added an external microphone between the two it will cause distortion and static.
Not knowing the configuration of your computer makes it harder to analyze the problem.
So hope this is of some help. Bud

Check for the Third earth wire of your computer else check for the motherboard taking earth for the cabinet.

 

Good luck
