If you have a PlayStation 4, there is a good chance that one of its HDMI ports is not working properly. This can be caused by a number of things, but the most common culprit is a bad connection. To fix this issue, you will need to take some steps. First, make sure that your PlayStation 4 is connected to the network and that your TV has an HDMI port. If your TV does not have an HDMI port, you can buy one for around $30. Once your PlayStation 4 is connected to the network and your TV has an HDMI port, try connecting it to the HDMI port on your television. If this does not work, then you may need to replace the HDMI cord in your television with a new one. Once you have fixed the problem with one of its HDMI ports on PlayStation 4, it may be time to fix another one if it exists.
