I recently bought a one4all universal remote that can be used on up to 3 devices. The remote turns the TV on and off, as well as changes channels and adjust volume. But, the remote will not allow me access to the TV's main menu so that I can program the TV to recieve all the cable channels. Right now I have about 4 channels, and I was hoping that buying this remote would help, but it hasn't, and I don't know how to alleviate this problem.
