Check your plugins to make sure the external speakers arren't plugged into the rear surround plugin. That usually makes an echo sound. Also try adjusting your equalizer. Right side of eq should be up higher, then middle should be a little lower, and left side of eq should be about the middle setting. If this works or not let me know

I have a brand new 55" smart TVs and when we set it up we could not get any sound,is there something we are doing wrong.


Check in the menu if there is a switch between internal and external speakers. If you are trying to use the internal ones and they are set externally, you will get no sound. The reverse is also true.

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 audio on my Olevia 42 inch screen flatscreen TV is echoing on every channel. Any ideas how to make it stop?


try external speakers and see if it continues, if yes, need new tv, if no, then use external speakers. (you also can try unplugging from power completely and see if that resets it).

INTERNAL SPEEKERS do not work external speekers work when pluged in


Hi,
Check the menu. In almost flat panel tvs there is setting that allow you to select in between internal speaker and external speaker. If the selected setting is external speaker the you wont get sound from the internal speakers.

How to fix sound on my lg 42


Some simple things you may already have tried but I will list:

Unplug set for a while and then plug back and see if sound--when unplugged the set may reset.

In main menu make sure speakers are not switched off.

I doubt it is mute but if also using some type of box check that its volume is not all the way down.

If internal speakers put your ear right to them---hear low sound or a buzz or hum?

If using external speakers of any kind look at the hookup and switch to make sure internal/external is correctly selected

If NONE of these help you have an audio problem and should first contact LG (yes it takes time on the phone) to inquire if some common issue or a possible software upgrade is available for this.

Last: Some failure has occurred either in the audio circuit or something that feeds it.

I've had my tv for maybe three years. I turned on the tv this afternoon, and I have picture but no sound. Can this be fixed?


Certainly. The only question is how hard it would be to fix it and how much it would cost. First, if you are on a cable service, try another set to make sure it isn't a cable company problem. Next, ask if anybody has tried changing sound options. Maybe somebody set it to run the sound through an external sound system with internal speakers off. Another possibility, if you intentionally set the TV sound to go to an external amplifier, is a pet, small child or person cleaning behind the set has yanked the sound cable, or the external amplifier is not working as intended.

If you've checked all of these, tried an external sound system (a "boom box" with an auxiliary input will do), and you can see the volume indicator bar go up and down without hearing anything, then you have a problem with the sound demodulator inside the set. If it works with an external sound system but not the internal speakers, the problem is in the internal amplifiers. A work-around until you can get it fixed is to use the closed caption system.

Adding remote control activated ''mute'' to TV headphone jack


Generally when the head phone jack is inserted the speakers will get disconnected automatically.

If you are going to use external amplifier you can try the AV sockets. Opening the TV you may require the special screw drivers some times.

No Sound on TV??


I would borrow a set of external speakers to see if I could get sound from the sound circuit at all, if not, then it sounds like the repair shop.
