I am not getting any video from my ps4
It’s likely that your HDMI port is bad. An easy way to check it is to just get a flashlight and shine it into the port. If any pins are missing, bent or jammed into the back of the port then it’s bad and you’ll need a new one installed. I say it’s likely because the original ports in these are really weak. It’s one of our most popular repairs. I hope this helps.
Is it plugged in to your TV/monitor via HDMI? If it is, try replacing the HDMI cord and get a better one.
