Hey guys,
I have a build that I set up for my LEDs on my LG OLED TV using a Raspberry Pi and I also have an external power supply. My issue is that every time the screen has a white color on the LEDs the power supply starts to make a very high pitch noise that most people can't even hear but I hear it and it drives me insane. Do I need a larger/higher quality power supply?
