Can you actually see the volume bar when this happens and does it only happen if you try to change the volume with the remote and then it takes off on its own?
Ok, we are not allowed to contact outside the site as they will not allow us to do so, sorry. It will not even show your email shows xxxxxxxxx@xxxxxx
Does this only happen/start on its own when you use the remote to change the volume?
If so then try using the volume control on the tv and see if the same thing happens and if not then try changing the batteries in the remote control. If that does not work and the volume works fine on the tv buttons itself then the remote is bad.
