Hey,
I was playing on my PS4 and have recently noticed a high frequency noise. When I turn off my screen, it stops.
I changed the HDMI cable and it doesn't seem to fix it.
Could anyone assist me in knowing what's wrong, and how to perhaps fix it?
Thanks

Could there be some eletrical interference coming from something nearby?

I have my PC and Phone in the room only. But, when I turn the screen off, it goes. Also, it appears to be doing it quite some time after I turn the PS4/Screen on (maybe an hour)

Sounds like you need to replace your TV or have someone who knows what they're doing actually take a look at it. Considering it happens after a period of use, something is changing as it rises in temperature, and that shouldn't happen.

could be bad capacitor if it is it might start to smell funny and you will hear a loud pop

My monitor makes a loud hissing noise when I first turn it on. It goes away once it "warms up", I believe it could probably be fixed if I dissembled the monitor and applied silicone grease. If I had to guess its probably your TV failing.
