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
