Question about Sony FD Trinitron WEGA KV-24FS120 24" TV

1 Answer

No sound through speakers, but ok through headset

Suddenly I lost sound through the speakers, but I still get sound by using the earphone jack. I've gone through the troubleshooting tips dealing with making sure I'm using the right settings, so I don't think settings are the problem.

Re: No sound through speakers, but ok through headset

U have a problem either on the speaker or on the sound amplifying circuit. signal coming from the earphone jack is not amplified. check the speaker first. if its ok then check the audio output ic(integrated circuit). good luck!

My jvc tv model LT32A80SU has a picture but no sound what could it be

Aside from a audio circuit problem:

Look to see if the set has a earphone jack--sound that way?

If set has rear connections do you have sound with a DVD player etc?

Look in the main menus for a setting that speakers are not turned OFF>

No sound

check the volume adjustment first, if ok tried to hooked up a powered pc speaker at the earphone jack of the tv. if you get sound there it could be the speaker is worn out. if can get sound from the earphone jack, the amplifier circuit or the amplifier ic was defective.

No sound for earphone, there are no rca jacks, the earphone is used to attach speakers, but there is no sound from the earphone jack

if their is a sound from the internal speaker then the problem is with in only in the earphone jack or in the connection. to access the internal part of the tv you need to remove the rear cover. locate the earphone jack terminal re soldered and check the connection at the board ( PCB). you can check also the continuity, attached powered pc speaker then use an analog tester and check weather their is a connection coming from the stereo input jack going to the terminal of the earphone jack of the tv. if no connection replace with new earphone jack. good luck hope this can helped.

Lost sound on sony trinitron tv


there are so many reasons why your TV won't bring out sound. You need to troubleshoot first, in order to get to the root of the problem, before a solution can be proffered.

First, connect a DVD player to the TV, observe if there is going to be sound. If there is still no sound after connecting the DVD player to the TV, proceed to the next step. "The reason why I asked you to connect a DVD player to the TV is to confirm if the problem is simply not from the audio cord connected to the TV."

Second, get an headset, connect it to the earphone jack of the TV and observe if there is going to be sound. If there is no sound, then it is glaring now that your TV is having a defective sound card/IC that's why it is not bring out any sound. (Note that connecting an headset to your TV is optional because not all TV's has a space for headset). "The reason why I asked you to connect an headset to the TV is to also confirm if problem is not from the TV speaker. Though TV speaker problems are rare but sometimes, the TV speaker might be defective or the speaker wires may have loosed contact or cut into two, due to one reason or the other. But if the headset doesn't bring out any sound from the TV, then it is not so."

If none of the above seems not to be the cause of the problem, then the above troubleshooting has confirmed that the TV has got a defective sound card/ic. The sound IC/card of the TV has to be replaced for the TV to bring out sound again.

To be honest with you, replacing or fixing the sound card/ic of your TV requires the ability or experience to do so.

Now, if you are convinced you can fix or replace this yourself, please reply so that i can help you further. And make sure you troubleshoot first, before getting back to me.

I have a 1993 Toshiba 32 inch tv. suddenly there is no sound. The mute is NOT turned on. What might be the problem?

Hi kohn,

Plug your headset to the earphone jack (if installed) of the TV.

If you can hear the sound there, the fault may due to open(defective) internal speakers or the earphone jack itself. Faulty internal speaker may replaced with new sets to back your sound to normal again. If the earphone jack was faulty, you may spray it first with electrical contact cleanerwhile inserting and pulling the headset plug into it for one minute to clean the contact. If nothing happens, this jack need to replaced with new one.

If you can't hear the sound after inserting your headset, this is an indication that the audio circuitry was gone bad. The most common caused of this trouble was the faulty sound IC(mounted in heatsink). This is the one converts the audio signal to sound and feed to your speaker's. I would advice you to look for a qualified technician to check this parts.

Hope I helped you.

Have a nice day!

Thanks for using Fixya.

The TV has absolutely no volume, except if you are using headphones

Hi satisfy_2liv,
The fault was came from the headphone jack itself, when you connect the headset to this jack, it will open the internal contact to the speaker of the TV and you will hear the sound only in the headset. But the problem is, it will not get back to contact once you pull-out the headset to return the audio signal to the speakers. This may probably has a dirty contact or totally faulty. Bad solder joints is also to consider in that area. First you may spray contact cleaner to the jack while inserting and pulling the headset plug. If symptom still persist, check the board for bad solder joints. If the joints isn't the problem,replaced the earphone jack and your unit will back to normal again.
Hope I helped you.
Have a nice day!

My sound does not work, what can I try?

If there's a earphone jack on your unit try to hook up your headset to confirm if it where the fault is. If you hear the sound from your headset then the fault is on the speaker,its connector and the earphone jack.

If there's no earphone jack then leave it to the expert to do the job.
I've suspect that you have a problem on the output IC or on the IF transformer.
This is technical that's why I've advice you to send it to repair shop.

But first check if mute is not on.

No sound

If picture is OK and there is no sound output from your tv, means either its speaker or the Sound output Ic is not working. The case of speaker fault can be easly detected without opening the TV. You just place your ear very near to the speaker side and switch on the TV by AC mains [not with remote control]. You may hear a "thumb" SOUND OR A "HUM" sound from it. If any one is there the internal speaker is working fine. The fault lies in audio output Ic stage. If there is no sound said above, speaker can be suspected. Befor confirming that the speaker is faulty, if your TV has an earphone or headphone jack in front, insert the earphone or headphone socket into it, and check whether there is any sound heard from it. If there is sound from headphone, means that the headphone socket is faulty, it does not bypass the sound to the speaker. When head phone is connected, the connection to the speaker will automatically cut of. When it is pulled out from the socket, the speaker connection will resume. If the changeover switch inside the earphone socket also show this kind of trouble. If the speaker inside is found faulty, unscrew it out of place after opening the TV, go for a same type and number, impedence and shape.
If there comes the above said "HUM" sound from the speaker, surely the Sound Output Ic is faulty. Replacing it will solve the probelm. Before replacing it, check it soldering points for any loose contact. It is best to resolder all suspected point is sound section before replacing the ic.
Note: In modern TVs there will be any trace of sound, without a video signal. Without video, sound is muted. ok.

How do i fix the volume because i do not have sound? my tv has no volume/sound. tried turning the tv up and down but still no sound

1 - hi
2 - check the jack for headset

3 - if you always use this jack for head set its maybe got problem = when push or pull the headset jack if you hear any sound from speakers your headset socket should change
4 - if you didnt hear any sound from both (speaker and headset) it means your ampilifire should repair

No sound

There are only two easy possible reasons:

1) IF it has a earphone jack of some kind it may be damaged or bad.

2) Place your ear to the speaker and turn the sound all the way up to see if you hear anything.

If not a problem with a earphone jack or a bad speaker it will not be economical to repair---for this size set better to just replace it.
