It is very essential that you removed the plug otherwise the speaker will not work. inside the jack terminal is a sort of mechanical switch that whenever you put the plug it switches off the speaker and removing will returned to on position.

Trying to get new headphones to cancel speakers on tv


What kind of headphones and TV are you trying to make work as an combined pair? It sounds to me as though you have your head phones plugged into the speaker location on the TV which could be a small hole that shows a pic of speakers. Look on the TV for an 'mic' or 'pic of headphones' holes. If there is an plug in hole with either it states mic or shows a pic of headphones plug the headphones into that hole instead of where you have them plugged into now.

Another suggestion is to use MDI cords in which you may already be using aka white, red, yellow colored plugs. If those plugs are assembled in the slots incorrect that also could be the reason as to why the headphones turn down when you turn the volume to the TV down; which also would influence the TV volume its self to also disengage to go either louder or quieter. MDI cords should be plugged in the following pattern to be categorized as the following with each color following the next color; yellow, white, red. Now if you are using MDI cords presently do you have them plugged in front or back of the TV?

If the TV has hole ports in both front and back for MDI cords then reverse your plug ins. Example: If you have them plugged in the front instead switch all three to the back of the TV or vise versa.

Also another thing; since you are wanting to use headphones for your TV speakers instead of the TV speakers themselves usually plugging headphones in are controlled by TV volume buttons; however I am assuming that you are trying to state that when you plug headphones into the TV you still hear the volume in your ears and anyone in the TV room is also still hearing the TV even though headphones are plugged in, am I right?

With you wanting to cancel the speakers on the TV out only attempted to use TV volume for speakers and without it working means you have the MDI cord plugged into the audio which would cause the TV to power the volume for the headphones anyways. May I ask this; since I am a bit confused, alright are you wishing for the headphones to be able to be loud enough so the TV only powers them for volume when you use the TV?

I know that headphones being plugged into an TV should only keep their volume within the ear buds. Therefore I have never heard of headphones being able to be loud enough to power out room sound. Instead they power internal volume which would be within your ears. Headphones were meant to keep noise and volume from surrounding a room to block room noise out and to keep the sound for your/ an own persons only listening capability. So because of this I am confused as to how ear phones would have the ability to sound the room with audio.

I can understand that if what you are trying to say is that the speakers on the TV still output volume even with head phones plugged in which would be an issue, since head phones are to capture the volume and noise from the unit in which plays aloud- to actually silence it instead- for the individual whom requires or presumes to have themselves to be the only listener.

NO sound on portable DVD player after plugging headphone


One of two situations: Plugged in headsets connect to contacts inside of the female port on the player. If any of the internal connections within the female port are shorted the player switching component will not disconnect and thus the player speakers will not function. Could be dirt, metal particles from the surface of the head phone pins, or just a defective female jack. You may try to insert a small round probe (like a tooth pic etc.) saturated with rubbing alcohol and twirl the probe around to collect any deposits off of the integral connectors. Be careful Not to break the probe off inside of the port. If after this attempt the same problems exist; only a qualified technician can observe the interior of the player for electrical disfunction.

The green plug audio jack a piece broke off in it and is stuck inside the green audio jack in the back no sound is coming to computer


You will have to have a electronics tech check that, because the jack has thin metal strips that make contact with the plug you plug into it so the sound is delivered to the speakers or whatever you have plugged in to it, also if you computer has built in speakers that also do not work now, in the same jack the thin strips of metal also serve as a switch that routs the sound to the plug that is plugged into it, or routs the sound to the internal speaker, so if this piece that is stuck inside the jack is preventing the metal strip from making contact either to the plug or the switch to route to internal speakers then you will not get any sound from anything.
If your comfortable with electronics you could open up your computer, locate the jack and see if the back side of the jack is open (has a hole that lines up with the one on the outside), if there is an opening you could try to use a round toothpick and "carefully and very easy" attempt to push the piece out from the back to the outside of the computer, with the toothpick, DO NOT FORCE THIS! If the piece that is stuck, is really stuck you can damage the metal contacts in the jack to a point it would need replacing.
Now the great news is, and only if your good with electronics and de-soldering and soldering, this output jack is most always a common eighth inch stereo headphone jack that you can get at Radio Shack for a couple bucks. However if you do know how to change the jack make sure you follow static protocols when the card is not plugged into your computer, and if the plug is right on the motherboard use caution with too much heat from a soldering iron, most motherboards have several layers and too much heat can damage a layer beneath the jack. (typically a 35 watt soldering iron in good clean condition works best)
I hope this helps!

I have no speakers so can i get sound without them


You can definately get sound without them but you must have an internal speaker inside the computer. an alternative option would be to plug headphones into the line out port in the back of the computer.
Now you will need to check inside the computer for the internal speaker. It will be a little black round plastic bit with two wires it should be plugged in to the motherboard at the bottom right hand corner. This is the Front Panel Instrumentation and Illumination Area or just F_PANEL for short on most motherboards. If there is one plugged in, then you need to go to the audio properties and select internal audio.
Hope this helps.

When I plug in a headphone from the jack in the back the sound still comes out the speakers not the headpone. Element fxl-1910


Is your Headphones ok - Have you tried them on something else?

Is the plug on the headphones of the correct type and size?

If you mute the TV or turn down the volume - does this affect the headphone volume?

Also, Do you get sound out of the Headphones at the same time as the speakers?

If the above checks out to be OK - You may have a faulty Headphone socket in the TV.

Normally when you push headphones into a TV it usually pushes a piece of Metal in the head phone socket that disengages the speakers
The socket can go faulty

No sound


I had this problem as well. I would get sound from headphones but unplugging them I had no sound from the builtin speaker.

When you plug in your headphones it moves a thin piece of metal in the jack which interrupts a connection (this is a good thing) so it can know when to disable the internal speaker. When you unplug your headphones the piece of metal moves back and it enables the internal speaker again.

I was able to fix this by taking apart my x51v and bending the piece of metal a little while the headphones are plugged in so that it will contact better when the headphones are unplugged,

To take your axim apart there are 4 screws on the back underneath the rubber grips that you need to take out. Then you can just slide a finger nail up and down each side to remove the front and back of the casing. The back you will need to swing out from the bottom since it hooks over the headphone jack. I unplugged the small wire that connects the front half of the case to the guts using a tiny flat screwdriver.

Inside on the back, there is a black plastic plate that is held on by 4 more screws. Take that off.

Now you can see the headphone jack. I plugged in my headphones and used a small flat screwdriver to push against the headphone jack on the bottom piece of metal on the right side with the axim face down. You can observe the piece I mean by looking at the side of the headphone jack when you plug and unplug headphones. It moves perhaps 1/32 of an inch.

Your goal is to bend the piece of metal closer to where it is when no headphones are plugged in. The only way to bend it properly is to do it when the headphones are in.

Sorry if this isn't clear enough. I'm not sure if this is a permanent fix or not but it's worked for me.

Sound in right speaker only


Do you have stereo headphones available? If so, try plugging the headphones into the computer. If both headphone speakers work then the problem is either in the monitor or the audio cable. If only the right headphone speaker works, then the problem is in the computer....probably a bent or broken contact in the audio output jack, or perhaps an incorrectly placed sound jumper on the motherboard.

Try to find another sound jack...for example, if you're using the sound jack on the rear panel...is there another one on the front of the computer?

Are you using the correct type of stereo sound cable? There should be three metal electrical contacts on the sound connector....a metal tip, a separate metal ring, and the metal sleeve. If there is only a metal tip and a metal sleeve with no ring...then you're using a "mono" cable that will only support one speaker.

If the cable and computer are ok, then your monitor probably has a problem with it's left speaker. You'll need to take it to a qualified computer or tv repair technician to track down the exact cause and repair it.
