I have an older model samsung smart 4k tv (UN65JU640D) and it wont recognize old roku SE
I have a samsung smart tv model UN65JU640D and a roku SE which is plugged in with an HDMI cord. The cord works....I can connect my iphone to the TV without a problem. The Roku works on other tvs. Could it be that I need a newer model roku to work with this tv?
Have you tried plugging in your Roku device into another HDMI port on the Samsung TV? The fact that the device works fine on other TVs but doesn't work on your Samsung probably indicates a connection issue.
