Samsung TV no longer recognizes HDMI?

I really needed your help. We have had a PS4 for a long time and everything has always worked well. But since yesterday the television no longer recognizes the HDMI. Everything is set correctly and the HDMI cable works.

Have you ever had something like this? I tried to lock the television completely and press the power button on the remote control for 20 seconds. Unfortunately it doesn't work that way for you.

Below you can find pictures of what it looks like.

Sure that the hdmi cable works? If so, I'd say it's the PS4
