I followed steps below and it worked for me on my Samsung 55F7000 TV:
1- Power off all HDMI devices connected to TV
2- Disconnect all HDMI cables from TV
3- Power off and unplug the TV's power cord from the wall outlet
4- Press and hold the TV power button for 30 seconds
5- Reconnect HDMI cables back to HDMI ports on TV
6- Re-plug the TV's power cord back into the wall outlet and check the TV.

Has anyone received a solution to this issue.
I have a week old 50" 2020 Frame TV. HDMI inputs on one connect DO NOT work!!! After spending multiple calls with Samsung support there only solution is to replace the One Connect Box. It's now been replaced 3 times and HDMI inputs DO NOT work still. I'm ready to return the product but wondered if anyone had a resolution?

Hello. I am having same issue with my 32. It is a few years old. Cant get any hdmi ports to work. All components and cables work fine on other TVs.
Please advise how to resolve.

Well, this is a bit of a worry. A few weeks ago, we bought a brand new TV (T5300). Within days, one of the HDMI ports stopped working and shortly after that, the TV itslef stopped working completely. So we returned it and got a like-for-like replacement. And now, one of the HDMI ports of that 2nd TV stopped working too! I've just followed the instructions provided on this thread and both HDMI ports are detected and seem to work properly again but is this issue going to keep happening and will I have to keep following those instructions over and over again? It doesn't give much confidence in the product I must say. We were given the option to get a replacement TV from a different manufacturer but I assumed we had been unlucky with the first TV and got a faulty one. These things can happen and I was happy to get the exact same model. But if this is a known problem and it keeps occuring, I'm afraid I will swap it for a different brand next time.
