My volume button goes all the way up to the max

It looks as if your volume up button is stuck, either on the TVs manual buttons or the volume up button from the remote. To check if it's the remote, put the remote away from the TV, either in a drawer or take the batteries out. If the same check the Volume up button on the TV, it may be pressed down & stuck in this position. If this is ok most likely the volume button will be at fault & need replaced.
