What is going on with my TV?

So for some reason after have the tv for a while the screen started to go black, but the audio still comes out. It does it on all 3 hdmi ports. I switched the cable but it still did it. It seems to only do it when im using my ps4. But I hooked up the same cord and playstation to a friend's TV and it worked... show more So for some reason after have the tv for a while the screen started to go black, but the audio still comes out. It does it on all 3 hdmi ports. I switched the cable but it still did it. It seems to only do it when im using my ps4. But I hooked up the same cord and playstation to a friend's TV and it worked perfectly. I didn't notice it happening when I put my switch on the TV. It mostly does it when im watching something or playing a game. I change the channel then back and the picture comes back. Same when I unplug the hdmi cord and plug it back in. And when the screen goes black the settings still come up on the screen for the TV. Does anyone know what could be causing this?
