After completing the setup process, I found that only some of the remote control functions were working. I called the company's support. After a short delay, I spoke to a living person. I explained the problem of the restricted function. After checking the serial numbers, she explained to me that this remote control was only partially compatible with my old flat screen TV. She said I can return it and try a different model, but there's no guarantee other devices will be more compatible. I have found that I can make changes to the setting using the manual setting and the 'OK' function on the remote control. It was pretty cumbersome, but the workaround worked. Enjoy often. John
