I got this telly for my daughter and it has worked for over a year fine. Now the volume doesn't work. I've tried to mute and unmute, turned it right up and down and still nothing.
Have you looked at the headphone jack? Sometimes a set is left plugged in and sound wil not come out of speakers.
Also, look at cable box. It can sometimes have a separate volume control.
last, if you plug in a set of headphones and you hear sound, pick up a pair of inexpensive powered speakers and use those.

A repair like this is in the vertical drive/output section of the TV set. It could be a simple capacitor causeing this problem or a combination of the capacitor and the output IC. A repair like this should not exceed 120 to 150 US. Is it worth that to you? How much can you replace it for? Good Luck PS please dont forget to rate this thread.

I think the ploblem should be the horizontal output that may be shot circuting working voltage,
apperently if you are not a qualify technician I recomend that you seek the help of such technician

If you removed power by turning off power itself to the set instead of turning it off by turning the set itself off---that is not a good thing to do.
When power is restored a surge can and likely hit the power supply in your set---time for a tech or shop to open it---I suspect they will find the standby or main power supply is damaged or now bad.
