PS4 Slim 2016 No image/audio but playable with remote play

Hey! Have my almost 11 years old PS4 slim, while seeing a video on YT app, suddenly it lost all image and audio. If i plug the headpones on the controller it sounds, then i try to see if remote play works and yes. What possibly be? HDMI looks good, Could be the PANASONIC?

I take it to a repeair guy but just erase all my HDD the dude, so i cant play anymore. But i want it to repeair by myself.
greetings!
