If your Playstation 4’s HDMI port is not working properly, there are a few things you can do to try and fix the issue. First, make sure that the HDMI cable is properly plugged into both the Playstation 4 and the TV. If the cable is not plugged in properly, it can cause problems with the signal. Next, try restarting both devices if they are connected by cable. If those steps do not work, you may need to replace your Playstation 4’s HDMI port. ..
