Troubleshoot issues with your Optik TV HDMI signal

HDCP explained

High-bandwidth Digital Content Protection (HDCP) is a form of digital copy protection that prevents copying of digital audio and video content as it travels across connections. This latest standard HDCP 2.2 was enforced as a result of content producers’ demands to protect their content. HDCP2.2 was not yet implemented when 4K (UHD) TVs were initially manufactured.

However, most 4K TVs sold since 2015 are HDCP 2.2 compatible. To check if your TV is HDCP 2.2 compatible, check your owner’s manual, check the support pages for your TV, or contact your TV manufacturer.

When connections are attempted between your TV, your video cable and your digital box they can sometimes fail resulting in the error messages listed below. These errors can be random and sometimes more frequent but can often be resolved with a few simple troubleshooting steps.

If you see either of the following error messages;

  • Your television cannot support HDCP video over your high definition connection. (H1001)
  • Unable to display video service over HDMI. HDCP link integrity check failed. (H1005)

Follow the tips and steps below:

Quick fixes

First, be specific about the sequence used to power on
your digital box and TV

Try this sequence first as HDMI errors rarely occur when the tv is turned on first.

  1. Turn your digital box off
  2. Turn your TV off
  3. Turn your TV on
  4. Turn your digital box on

Second, check your HDMI cable

If you are still experiencing the issue, try to unplug and reseat both ends of the HDMI cable

Third, try a different HDMI cable

Try a different HDMI cable to see if the issue goes away.

Note: If you do not watch 4K programming you can try a component cable.

Fourth, reboot your digital box

Reboot your digital box by holding down the power button for 10 seconds.

If the problem persists

Check and try different inputs on your TV. Specifically, look for the HDCP compatible connections on the back of the TV.

To verify your TV is HDCP compliant:

  • Check the box that comes with your television.
  • Consult your TV user manual. Read the video-cable section and see if it lists HDCP anywhere among the definitions of video ports. If it does not, your television is likely not HDCP-compliant.
  • Call the customer service line for the manufacturer of your high-definition television. Give the representative the model number of your television and ask if it is HDCP-compliant.

If the TV is HDCP compliant it should have the following types of HDCP compliant connections

  • HDMI (4K@60Hz)
  • HDCP 2.2
  • ARC

Verify that the HDMI cable from digital box is plugged into one of these connections (HDMI (4K@60Hz), HDCP 2.2 or ARC)

Verify you have selected the correct output on your TV menu

Using your TV remote input button, make sure your TV is set to the correct input.

Note: Your TV manufacturer may have a different name for the input button, for example TV/Video, Input, or Source button

  • Try to look for HDMI, HDMI 1 or HDMI 2.
    Note: If you don’t have your TV remote try using the input button on the TV itself.
  • You may need to press the input button to cycle through the inputs.
  • When cycling through each of the inputs, wait for 10 seconds on each selection so the television can establish a connection to any connected devices.
  • Try resetting your remote. Visit Program your Slimline Remote
  • Verify that you do not have any devices (such as an audio receiver) between your digital box and your TV that is NOT HDCP compliant. (If you do have a non-compliant device, you may need to use a secondary audio connection on the TV).
    • Alternatively you can use an optical cable to connect your audio receiver to the TV

Ensure that your TV firmware is up to date

Go to your TV manufacturer’s website and check if your Smart TV is on the most recent firmware as some of these connection issues are known to TV manufacturers and are resolved over time through firmware updates.
