PS5 Black Screen Pop

[sutoka]

Bought a PS5 off eBay, excellent condition and plugged it into the HDMI and ethernet cable I had my PS4 in. Every now and then when I'm playing a game, FIFA 23 etc the screen goes black for about 1 second then goes back to normal and you get a 'pop' sound. This happens maybe 2-3 times in say 20 minutes. Playing through a Toshiba 4K Smart TV. Hopefully something simple.
