I have a Samsung 55NU7300 and bought it just over a year ago and yesterday the tv seemed to gain a mind of its own and the volume would just keep going up and I couldn't stop it. I tried switching it off from the mains and left it for over an hour and trying to see if the auto volume setting was switched on but it didn't work. I'm not sure what else to do.
This happened to my Samsung tv yesterday too. I tried some of the reset suggestions online and non work.
is this just a coincidence? The tv is only 18 months old so I'd be interested if you found a solution!!
I really hope it's a glitch or something must have gotten shaken up internally as my tv hasn't done that since the day I posted my question on the forum.
Hey! Does this issue occur when using apps or just randomly? Does it happen when you are using an external device connected to the TV? When the volume increases by itself, can you see the Volume Bar on the screen?
Since the day I posted this, I found that the best way to stop this from happening is to unplug your tv from the mains for a few hours or the entire day. It should stop doing that.
