Hi there. I just bought this remote ARQ-100. At first it wasn’t being recognized by the B5. After a few hours of not using it, it is working BUT the keyboard in the back doesn’t work, just the 4 cursor keys. On the front most work, but can’t seem to pair the power key for the TV and the Favs button doesn’t goto favorites. Any thoughts? I bought this remote for the keyboard. lol. Thank you for any suggestions.
