There are countless "me too" threads on this forum with this problem. I don't understand how Samsung can just ignore them and repeat the same nonsense about running through the setup again or resetting the remote. It's also insulting to close these support tickets without a valid solution. What seems clear is Samsung pushed out a firmware update some time last year that broke universal remote functionality with a whole host of cable boxes. Perhaps this was intentional, but I for one am **bleep** off that they removed a valuable feature I have relied on for years. I have been using the universal remote with my Samsung TV and Spectrum Cisco set top box for about 5 years now and it has worked perfectly until several weeks ago when I attempted to set up the remote again. I have gone through this same process numerous times when disconnecting and reconnecting the hdmi input. Only when you go through the setup now, it gets hung up trying to detect the up and down channel buttons. The LED on the remote literally gets stuck on red like it can't detect something. I've tested this with multiple Samsung authentic remote controls and they all fail. Even entering my model for the Cisco manually fails. What's also clear is that it's not a hardware problem because when you bypass the up/down check and answer yes, it completes the registration and then proceeds to do its own change channel test which works, so the TV is communicating with the cable box. It seems more like an interface problem between the remote control and the cable box. So Samsung, please get your act together and admit the problem and either provide a fix or a way to downgrade the firmware.
