Re: problem with headphone jack

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.

Sound won't work on my Disney dvd/tv combo

Either the speaker is bad or broken wire OR more likely the headphone jack is the issue---when jack comes out it lets a leaf in the socket engage the speaker back----when used a lot the jack causes no sound.

How can I get headphones to work with my Symphonic WF203 TV?

This set doesn't have a headphone jack, nor does it have RCA audio output jacks. Without one or the other, you're out of luck connecting headphones to this TV.

I remember a product some years ago that allowed adding headphones using a small microphone placed in front of the speaker. This was hooked to a little amplifier that ran the headphones so the volume could be independently controlled. It was marketed as a way to let "hearing-impaired" family members listen to TV shows without needing to make it uncomfortably loud for others. I haven't looked, but something similar might still be available. It's cumbersome, though, and needs power, plus maybe being costly if you find one.

It's possible to add a headphone jack, but you need to know how to do electronic soldering. Find a spot on the case where you can make a hole and mount a headphone jack, then wire it to the speakers. If you want the headphones to cut off the speakers when plugged in, you need a switching jack, and the speaker wires need to be cut and connected to the correct terminals. The switch built into the jack then disconnects the speakers when the headphone plug is in. If you don't need to turn off the speakers it's a little easier. You just need to wire from the jack to the speaker terminals. I've added jacks on quite a few sets. If you don't feel up to it and don't know anyone who is, you can see if a TV shop (if there are any left in your area!) would do it. (The shop I used to work for charged about $20, including the jack, but that was over 10 years ago now.)

Good luck, and thanks for using Fixya!

Ok so 1 of my kidos has the RCA 20F420T tv, and i guess there is no headphone jack hole, so i went and bought adapter that plugs into the av jacks, still doesnt work can you please help!!!

Without knowing the specifics on this adapter - I can provide only provide some clues as to how this works.

Basically, the A/V jacks on a TV has a "fixed" audio output level - this means that the sound levels on the A/V jacks is NOT controlled by the volume control of the TV itself. You should be able to set the TV volume to minimum and then use the adapter's volume control to make the earphone / headphone sound louder and softer. Your TV however, may have a setting in the menu that can change the audio from "fixed" to "variable". If set to "variable", when turning the volume down for the TV's built in speakers will also turn the volume down on the A/V jacks as well. You do not want this to work like that as the sound in the headphones and the TV speakers will be same - instead of the TV speakers being off and the headphones on.

I hope this helps and good luck! Please rate my reply. Thanks!

Where to hook up headphone jacks to allow TV speakers to continue working while using headphones I.E. I have jacks on front of TV but they do not give me out put sound. which ones should I use on back of...

Unless you have an external headphone amplifier, you need to use the headphone jack socket, if there is one. Some newer TV's allow for separate headphone volume and speaker volume control.
Have a look in your user manual.

How to find JVC AV27320 headphone jack? I've plugged into the avs(red & white) in the front panel as well as the extra ones in the back. Altho - I CAN hear the sound thru the headphones, The external...

This model doesn't have a headphone jack. The only JVC TV in the series that does is the model AV-20D202. For the JVC AV-2732, use the RCA audio out jacks with an RCA to 3.5 mm adapter to connect to the headphones. The front audio jacks are audio in (for the audio from a video camera for example).

When you use any external speakers or headphones through the audio out jacks, make sure to turn off the TV speakers. Press Menu and navigate down to TV Speakers (up/down arrows). Then use the right/left arrows to select Off and then Exit the menu. Make sure you scroll the TV volume before doing this. Note: if your headphones do not have a volume control they are a bad choice for this type of audio output.

You can find the manual for the TV here: .

I wish that I had better news for you.

TV has no sound


You haven's specified nothing about the picture. Picture is Ok and there is no sound I thinks and posts this solution

Either your TVs speaker or its sound out put ic has damaged. To check it and conifrm you just do this first. There is a stero headphone socket on the front panel of your TV. Insert a headphone pin inot it and listen whether there is sound output come ffrom it or not. If there is sound output from the headphone socket, and not from the speaker, be sure taht the speaker is out.
If there is no sound output from the headphone socet, wither your TVs sound output ic is damaged or it doesn't get proper voltage to go on. It is very easy to locate this IC, as speaker wire goes directly to this section. Just follow the speaker wire and locate the IC, usually screwed on to a metal heatsink. Check its input voltage. If there is no voltage to that IC, check the track associated with that pin. If there is voltages and still not works. first resolder all the pins of that IC by applying a little more solder, whout shorting the adjecent terminals. If this does not helps, replace that IC with same type and number. OK.

I was watching tv, turned the channel and the sound quit. I turned off the tv for awhile and still no sound, on any channel. Is there anything I can do to fix it or do I need to take it for repair? It is a...

the speaker may have quit working. or possibly if the t.v has a headphone jack something may be in the hole causing te=he t.v to send audio to the jack instead of the speakers. if that is not it if you do have a jack for headphones you can plug in an adapter to hook up your media to an external speaker device, the first place to look is this jack, if no sound will come through your headphones either thanyou have an internal problem

Low Volume from headphone jack...

I do not think that this TV does not have a separate circuitry with its volume control for the earphone. If your earphone is mono, are you using a plug that is mono to connect the speaker?
Try using AWG 20 if you could to see if that helps.
Good Luck.

TV has no sound

Just a thought...does the set have a headphone jack? When you plug in most headphone jacks it disables the internal speakers. If it does have a headphone jack trying plugging in some headphones to see if you have sound there. If you do, plug/unplug it a few times...worth a shot.

Audio output jacks

If I remember this tv correctly, check under the audio setting in the menu, most tv's including this on have variable output for the audio o/p. meaning the the o/p vol. is adjusted as the tv speaker vol. changes. some tv's will put out a fixed audio o/p to the rca jacks, but will only do this when the speakers are shut off in the menu (not muted, but off). I have run into this problem many times & have yet to find a better solution to getting a steady sound sound out of the o/p jacks.
