I purchased a Sharper Image wireless TV speaker to hook up to our LG Smart TV. I had already returned two other wireless TV speakers before this purchase because one stopped working after a few weeks and the other stopped working after a few days. Obviously there is something either interfering with this setup or something needs to be changed in the LG TV audio output? We are ready to give up and return this third purchase unless we can find some help. This is a wireless speaker needed for a hard of hearing person and when they work they are fantastic! We do have cable TV with an HD router hooked up to same TV. Thanks for any help you can give us!
