Hi everybody , im new to the site and have a realy strange issue that i just cant work out why my front and left speakers wont increase in volume but will decrease !! Ive tried everything from changing sound affect mode and the front speakers still wont do what i need them to do !!, ive even gone to home set up but it seems like they are locked on volume 5 but wont increase to +5 , they will only be allowed to be lowered !! , every other speaker works exactly as it should including the sub , how can this be or is it just a normal standard set up ie default setting within this model ? , realy frustrating and cant work out why as been trying for a week now without joy , hoping somebody on here can help and very strange .LG HT806PH
