Since all possible user level steps have already been tried out that didn't fix the issue and it indicates that problem is hardware related, there are two circuit boards in TV that can be cause of it, either touch control board which is generating volume high and low command on its own and this signal goes to main processor chip OR the main controller chip has got internal issue and generates volume change command itself.Replacement of touch control board in TV will help to resolve the problem or it would confirm that main board is defective. Please check following supplier link where touch control button board is available for $10 and it worth to give it try if you are working on i yourself..http://www.shopjimmy.com/lg-ebr72671301-ir-touch-assembly.htmIf you are not comfortable working on it yourself then you may please use following link to get list of TV repair shops in area which will help to get repair quote...http://www.tvrepairpros.com/If touch control board replacement doesn't fix the issue then it will confirm that main board is bad and should be replaced.
