PS5 Black screen during gaming on new TV

I have changed my tv recently, plugged PS5 in, played EA 24FC, finished a game, all fine. It then goes to start a 2nd match, audio plays but screen goes black. Only way around this is to turn tv off then on via remote quick. I have changed HDMI, changed resolution settings, video output. turned off HDCP and other settings, but nothing. Same issue. Everything ive seen to try online ive done. Out of ideas!
