What make and model tv .
Most if not all flat screen tv's do not have speaker outputs
but they do have rca audio outputs,these are marked audio output
and are round with a red centre,these outputs will require an external amplifier to power speakers.

No sound


Hi are you sure the mute button isnt stuck on your controll if this is not the case then it could be on the circuit board.
Have you tried changing the sound mode and see if this changes anything.
The only thing you can do if it is a board problem is buy seperate speakers that will plug into the audio out put connectors doing this will let you know if it is a controll or setting problem also if you try external speakers then you would no that it isnt a controll problem if you got sound through the external speakers then the chances are that it is a solder problem if the solder had gone on one speaker you could eliminate that as you would know where to look but as it is both the speakers, Im basing it on that you are using the speakers inside the telly and not external ones if you are using extra speakers unplug them and just try the telly ones.
So basing it on that you are just using the internal speakers then it could be a solder problem on the board where the speakers plug into.
It could be something as simple as a resistor gone or going these are cheap to buy but i dont sugest fitting yourself unless you have relevant testing equipment and a good knowlege of soldering.
So first i would try changing sound modes on the telly if this dont change anything try pressing mute button just to make sure that the controll and all its functions are working properly.
But after this if it dont solve your problem then you could either buy external speakers as this might solve your problem but if you want the telly working as it should be you will need all equipment and to be able to read a spec sheet and be able to follow cicuit diagrams.
Let me know how you get on and what you want to do

The Sound has stopped working on my telly


if you have sound from the headphone jack the sound circuit is good--audio headphone jack when inserted cuts off internal speakers--it could be 3 days old and have a problem with the jack.

Sony BRAVIA KDL-40V2500 audio not working


I would Google the model number carefully for "problems" "no sound" and usually this set will display some kind of error code===it may even have a hard reset to try===service manuals are available on the net/web to allow you to see how the sound circuit is set up etc.

How do I get the surround sound to work on the telly and not just through dvd


Using your stereo system for audio portions of video programs - such as DVD, VHS tape, etc, - is a great way to upgrade sound quality. Many people are in the same "boat" as you; trying to get the TV audio out of the TV and into the stereo.

You'll need to located an unused left and right audio input of your stereo. These new jacks may be assigned to "Tape" or something else - but for you, it will now be "TV". You'll also have to locate the left and right audio output for the TV. This may be located on the back of a cable TV box, satellite converted, Tivo, etc. if you such a device to receive TV signals. Simply follow the cable from the rear of these devices to the rear or side of the TV and disconnect. Reconnect the loose ends to the unused left and right inputs on the stereo. If you do NOT use one of those devices, you'll need to find left and right audio OUTPUT jacks on the TV itself.

Many older TV's only offered audio and video INPUT jacks, as there was no need to send signals anywhere else since the TV displayed the picture and had an internal audio amplifier and built in speakers for sound. If you TV only has input jacks, there will be no easy way to obtain the audio output signals. While you could pay a technician to get them out for you, you might be better off obtaining some type of tuner or converter to do the job you instead and do it for less cost.

I hope this was heklpful and good luck! Please rate my reply. thanks.

Phillips 50PF9431D/37: Perfect Picture, inuadible audio


The audio or sound IC (integrated Circuit) on the TV panel maybe bad and need to be replaced.
Also, the speakers of the TV may have a weak connection from inside the panel.
But my best bet is the first solution i gave. If u are not a qualified electronics technician then take it to a service centre.

Continuous crackling from TV speakers


I'm sure you have figured this one out. TV itself is causing the problems.
The circuit board that produces the audio signal seems to be the problem.
Before you call the repairman, go to the web site Shopjimmy.com just to get an idea of what the parts will cost. That way he doesn't rip you off.

I hope I answered your question correctly. Please rate me. :)

JVC LT 42x688 no picture just sound


Sorry, this has no easy fix. The good news is you do not need an LCD Panel. The bad news is the Video Processor has a problem.
This TV has x3 Boards. The one you should replace first is the one in the middle. If this doesn't fix it, try the one on the right. The Part #s are on the Boards if you wanna try ebay.
