Static electricity shorted as I went to turn my speakers off. now I have no sound, but the power light comes on.

Static electricity shorted from my finger to the off / on switch. Something shorted out and now I have no sound. The power light still comes on. There is nothing obvious on the circuit board. Any ideas?

click start control panel sounds and audio devices select advanced there might be a tick in the mute box untick it or select audio from the microphone drop down list

make sure you have the right one selected and in the volume box make sure the microphone box has a tick in it or select the voice tab and make sure that you have the right media selected also select volume make sure the box for microphone has a tick in it

if your computer came with a motherboard disk the drivers could be on it

Static sound builds up in the sub pops, then no sound comes from it. The sound comes back once I reconnect the power source and fiddle with the power plug. The problem then repeats.


Look for a wire strand or solder splash on any circuit boards or connections that might be 'almost' shorting out anything. Next, if there are any metal screws with very pointy tips (like sheet metal screws) that might be just a smidge too long and clip the very tip off so that it can't possibly short a frame to a component.

The idea is to find any reason why electricity might be bleeding over into another area of a circuit board that uses capacitors where a charge could build up causing the symptom you are describing.

If the electricity sound was loud and static sounding then you had a short with arcing which is not good and you blew a board or the socket that the bulb went into. Check that there is current at the bulb fitting.

Sherwood RX-4109 receiver has no sound. Right speaker had no sound, and I tried to see if switching speaker connections in back receiver would help, but now neither speaker works, and there is not...


Maybe a shorted right speaker took out the other channel. Does it turn on now?

Generally speaking, an amp protects itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.


Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.


You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.


If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.


If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

You can test the speaker for open or short by touching a small battery to the speaker wires. It should make static or click sounds. If not, it's dead. If it sparks and akes no sound it's shorted and dangerous to any amp.

There is static coming out of my speakers on my stereo. I I checke to make sureall the wires are connected properly and the power is plugged in securely. There is static with the sound on all...


Don't worry, it's more possible that you have the static electricity and through your stereo this electricity goes to the ground. Try touching another metalic surfasce (refrigirator, oven etc), try to change your shoes (especialy if your stereo is on a carpet floor and you walk on it) Sometimes when we are very nervous the static electricity on our body is higher. So keep calm.

Hi there , the green light just means its getting Power, it doesnt mean that its going to give sound, It could be that you dont have Drivers installed for your Sound card which is causing it too not get sound , but when it makes that static noise , its the Wire just causing Static with the Sub , just means its getting power , The + and - sign is the volume control ...Try see if you can turn it louder with the + . maybe it is low enough not too hear.....Hope this helped Bud

Clip light


It sounds like one side of the power amp has shorted. May be hazardous to the speaker so best take it to a shop for repair. If speaker stills sounds OK, probably the clip detector transistors have failed.

Static noise from Front Left Speaker


It would probably be with the speaker. That is easily checked by simply unhooking the speaker and running the test again.

Scratching (static) noise coming from computer speakers


I foudn this in anther forum:
I have an ASUS motherboard P5E3 Premium. The audio that came with it was the Sound Max audio. I also noticed abnormal sounds coming from the speakers. They included sounds during hard drive activity and also with mouse movement. They were not loud but noticable. I searched all over the web but didn't find the answer. I stumbled across the fix myself. I also have vista-64. In the sound control panel > speaker properties > levels... there is a pc beep slide bar. I noticed that if it is disabled then the abnormal sound went away completely. Problem solved. Hope this helps.
