I replaced my Roku 4400X with a 4850X because the old unit couldn't process the new PBS app. I used the same wiring that I had in place for the old unit. The TV is a Samsung 55 inch class OLED 4K S90C series Quantum HDR bought in February of this year. The new Roku was installed on Oct. 17 - today is Oct. 25, nine days later. In that period the video has failed twice. I didn't get the message number, but it was something about the HDMI connection. Basically it said to shut everything off and re-establish the hardware connections and then turn everything back on. The first time I did this and it solved the problem. I figured that when I installed the new Roku and moved the TV, maybe a connection was made less tight. The second time this happened I knew that nothing had been moved, so all I did was disconnect the Roku from its power source and then re-connected it, so that it would reboot. This solved the problem as well. I NEVER had this problem with the old Roku. What's the problem? Is the new Roku more sensitive? But if nothing has been moved physically, why should it fail? Do I need to get a replacement for the new unit? Please explain what's going on.
