I don't know your TV, but if it is controlled with IR (infrared) and the old FB still works, you can do everything if there are buttons on the One for all. I use it to operate Sony SmartTV and Bose Sondsystem (report under reviews). In normal operation, I only use the One for all. For special functions I use the original FBs or a keyboard. With the One for all I operate Netflix, Zattoo, Youtube etc. without any problems and with few keys. Sometimes the 0-9 keys are missing to call up the channel numbers directly. But the simplicity of the FB is ingenious and therefore my choice.
P.S If the channel keys 0-9 are a must, the model URC6820 from the same manufacturer can do that, but the navigation keys are different there and it is not illuminated.
