Step-by-Step Repair

  1. 1

    Check the input source

    Make sure the TV is set to the correct HDMI input. Press the Source/Input button on your remote and select the HDMI port your device is connected to. TVs often have 2-4 HDMI ports.

  2. 2

    Reseat the HDMI cable

    Unplug the HDMI cable from both the TV and the source device. Wait 10 seconds. Plug it back in firmly on both ends. A slightly loose connection is one of the most common HDMI issues.

  3. 3

    Try a different HDMI cable

    Swap to a different HDMI cable. Cables can fail internally even without visible damage. Use a High Speed or Ultra High Speed HDMI cable for 4K content.

  4. 4

    Try a different HDMI port

    Plug the cable into a different HDMI port on the TV. If the other port works, the original port may be damaged or have a different HDMI version/capability.

  5. 5

    Power cycle both devices

    Unplug both the TV and the source device from power. Wait 2 minutes. Plug the TV in first and turn it on, then plug in and turn on the source device. This resets the HDCP handshake.

If That Didn't Work

  • HDCP (copy protection) handshake failure
  • Source device resolution higher than TV supports
  • Damaged HDMI port pins

When to Call a Professional

If no HDMI ports work after trying multiple cables and devices, the HDMI controller on the main board may have failed. Board repair costs $80-$150. If only one port is damaged, using a different port is the easiest solution.
