The speakers need some kind of amplification, if you have something like a set of computer speakers connected and they are not powered they won't work, try connecting them to the headphone jack.
Let me know the set up, what kind of speakers, audio settings from the tv menu.

Connect with componet cables.


The only digital audio input for this TV will be via the HDMI input. Of course, even with HDMI in, you're only going to get a simple stereo output from the TV. You can use the analog L & R audio inputs for a very similar sound from the TV speakers.

The digital multi-channel audio (Dolby Digital, THX, 5.1, 7.1, etc) encoded in the program should be connected to a suitable multi-channel amplifier with either a TOSLINK (optical), RF (coaxial) or HDMI cable for theatre-like sound. This can be done by (a) cabling from the source (DVD, BluRay Disk, Set Top TV Tuner, etc.) directly to a multi-channel amp and speakers, or (b) from the HDMI output of these devices (DVD, BluRay Disk, Set Top TV Tuner, etc.) into one or both of the TV's HDMI inputs. This will provide only stereo sound output from the TV speakers. You should connect the TV's TOSLINK optical "Digital Output" jack with an optical cable to the amplifier's TOSLINK optical input jack to obtain theatre sound.

To listen to the program shown, you would select the amplifier input assciated with the optical, RF or HDMI input that is connected to the source (DVD, BluRay Disk, Set Top TV Tuner, etc.) if connected directly. If the TV HDMI input(s) are used, they are output to the TV optical output and should be connected to the amplifier optical input. The amp input associated with the optical input should be selected to hear the program with theatre-like sound.

No sound in bravia tv


for a better answer a model number is needed:

Speakers are not switched off in audio menu

Volume is not muted either on the set or a cable box if being used.

one of these or if you put your ear directly to the speaker/s and hear a buzz or very low sound---problem in audio output circuit.

A few sets also have internal/external speaker switch............

The speakers are not working. if i turn up the volume, I can hear static noise, but do not get any sound. tv speakers are on. I played around with the audio settinds and all the different hdmi ports,...


Hello
There are two possibilites for this fault. The first one is, damaged speaker voice coil and the second one is damaged audio output IC. To confirm it you have to open your TV. Speakers can be checked without removing them from the cabin fittings. Check them with the helap of a multimeter; set in OHms range. You can alos check it with a standard torch cell also. Connect the two terminals of the torch cell to the two terminals of the speaker [intermittantly, not constantly]; will produce a 'thumb' sound; if the speaker is good.
Connect the 'audio out socket' of the tv, with any other audio equipment, and listen whether there is sound form the external audio equipment, like amplifier or so. If there is sound from the external audio equipment, and no sound from the internal speaker of the TV, and the speaker is good, surely the 'audio output IC' of the TV is damged and should be replaced. OK.

I cant get any sound I did the trouble shooting


Changing the Audio Output
To switch audio output from the internal TV speakers to a connected external sound system or headphones:
Press 1. MORE.
Press 2. 9 (AUDIO).
Press 3. until the Speakers option is displayed. The Speakers option will display only if an A/V receiver connection has been detected.
Press 4. to switch between TV and either AV Receiver or Headphones.

Check if the MUTE key is on.
• The TV's "Listen to:" setting may be set to SAP (analog program from the ANT input) but no SAP is being broadcast.
• Check that the Speakers option is set to TV to hear sound from the TV speakers. Possibly sound is being sent to one of the audio outputs for an A/V receiver or headphones.
• If using an A/V receiver, check that the Speakers option is set to AV Receiver to hear sound from the A/V receiver speakers.
Press and hold the POWER button on the control panel for 10 seconds to perform System Reset.

The volume suddenly went out on our tv. you can hear static noise but no talking we havent had it but a few months ..


Hello
Either your TVs speakers or its output IC may have damaged. To confirm it, just up the volume of your tV, and try to hear the sound if any. If it feels like dostorted or very low-hard to hear, the speakers must be suspected. If there is no sound signal at all, output IC should be damaged. To confirm whether the sound detecting section is Ok, just connect your TVs audio output sockets at the rear of your TV with an amplifier or so, and rise the amplifier voluem, to get sound through it. If you get sound in this way, make sure that the above daid two items. Fist check the speaker, by connecting an external speaker in place and listen to it. If it also doesn't get the result, surely the output IC of your TV has damaged, and should be replaced with same type and number. OK.

My Protron tv does not have any sound, what could be the problem?


hi,
First of check that is the MUTE is on or not. Press the mute button on the remote to cahne the setting of mute.

the also the problem remains. you tvs speaker or the audio output ic have some problem. first of all check the speaker. Is it ok or not. for checking the same u have to open the tv. if you can then,

Remove the rare cover of your tv. find out the position of the speakers. remove the speaker connection from the board. It will be a socket you can easily remove it by pulling it.
Then take a 1.5V cell. The speaker will have to connectors from which the wire is connected. connect cell between it, if you hear a small cracking sound from the speaker the it is ok if not the speaker is faulty.

if the speaker is ok the the audio out put ic (integreted circuit ) will be faulty. u can see the audio output ic near the speaker socket from where you have pullout the wire. check the number noted in its top and bring a new one and replace it . for removing and replacing the audio output ic you should have soldering iron , de soldering pump and solder.
ok

The internal speakers/sound have quit working. I can hear the sound if I put my ear right next to the speakers but it does not respond to volume control or nay other controls in "settings". Any Ideas?


Maybe the sppeaker is faulty or the output audio amplifier IC is faulty.
You must remove and check first the speakers , if Ok then check for main voltage tot he IC, if not check power supply, If yes then the IC can be faulty.
You can easily use an audio signal to test and confirm

How do i hook external speakers to sony bravia television


The proper way to do this would be to use the audio output from the TV, either analogue left and right or the optical port, and send it into an dedicated amplifier or AV receiver. You can then use the amplifier or receiver to power the external speakers. If you are using a dedicated amplifier with no volume control you will want to change the audio output setting on the TV to "variable out" as oppose to its current "fixed out"settings. You can find this in the TV menu, usually under the audio settings. This will allow you to use the current TV remote to adjust the audio volume coming out of the external speakers.

46" Samsung LCD, no sound output whatsoever


First try hooking up a different source such as a DVD player or Cable box and see if you have audio. If you do then check the audio output from the computer. If you do not have audio then make sure the tv audio is up half way and turn off the set. When you do this you should hear the down chime provided you have the chime turned "on". If you do not hear the down or up chime then the sudio circuits on the Main bd are bad and the Main bd will have to be replaced. A quick way to check to see if the audio circuits are working is to listen for the up or down chime when turning on of off the set coming from the tv speakers speakers.
