How do you know if you need to have your PlayStation 4 HDMI port replaced? When you plug in your PlayStation 4 and power it on, the pulsing blue light goes to white, but nothing is showing on your TV screen. It is one of the most common repairs for PlayStation 4. The HDMI port at the back of your console is, unfortunately, a weak point for your console. It usually gets damaged by forcing the HDMI cable in, knocking your console over or by pure wear damage over time.
