Samsung One Remote UA75NU8000 won't control the volume. I have tried all the solutions that I have seen on this site. None of them seem to work for the model TV UA75NU8000. Samsung claim the remote doesn't send IR signals but other people on this forum have suggested ways on how to change this. None of those solutions have worked for me. The problem is that it used to work fine but now doesn't. Something has changed, I just don't know what it is and how to resolve it. Can ANYONE PLEASE HELP?!?!?!????
