HDMI connection not permitted can be caused for different reasons and according to the reasons there are solutions. The solutions are not very complicated to follow. Here, I am breaking down all the solution steps in the following-

Problem 1: Check the Cable Connection

If there is any issue with the cable connection of your HDMI, then you may face an HDMI connection not permitted problem. Sometimes, cables can go bad, or the connection is loose.

Other than that, any debris or obstruction in the connection can also lead to the same problem.


To solve the HDMI  connection issue, firstly, check the TiVo box connection setup carefully. Following that connection, disconnect the cables and reconnect them again. That way, you can solve the loose connection issue. 

Before reconnecting, make sure you check all the entry ports for any debris. Clean any such obstructions before reconnecting. 

If this process still fails to solve the issue, then any of the cables may go bad. If you find any bad cable, replace it with a good quality HDMI cable which supports up to 4k resolution.

Problem 2: Check For Software Bug

In some cases, an HDMI connection not permitted issue may appear due to a software bug. Software bugs can interrupt the entire system, and that is why connections not permitted can take place in HDMI.

Power circulation throughout the entire system is the best solution for solving the software bug issue. Here is the process-

  • Disconnect the TiVo recorder for 3 minutes 
  • Next, unplug the TV from the power source for 3 minutes
  • After that, disconnect the A/V receiver from the power for three minutes
  • Remove temporarily any third-party device in the TiVo setup
  • Finally, restart and refresh the TiVo setup

Problem 3: Check the A/V Receiver

If you have an A/V receiver connected to your system, the chance of an HDMI connection not permitted problem occurring becomes higher. Usually, when your DVR is attached to a larger number of TVs, and you are using an A/V receiver for each of them, this problem may take place.


To figure out the root of the problem, firstly, bypass the A/V receiver and connect your device directly to the TV HDMI input. If the connection is not permitted, the problem is solved. Here is what you need to check-

  • Check if the A/V receiver is connected properly to the power
  • Make sure the input is selected correctly
  • Check whether the A/V receiver is powered on

Problem 4: Check the Setting

Sometimes, an issue in the setting can cause an HDMI connection not permitted issue. Sometimes, turning off HDCP status can cause such a problem to take place. The solution is pretty simple for such settings issues.


Here is how to solve the setting issue-

  • Firstly, enter the display output menu
  • Locate the HDCP or HDCP status
  • Enable the HDCP status if it is disabled 

Even if you find the HDCP status enabled, still disable it for once and enable it again to make HDMI work.

Problem 5: Use Troubleshooter Setting

If you have tried everything that has been mentioned earlier and are still getting a not permitted problem, then there might be an undefined internal issue. Your TiVo box can resolve such internal issues by itself.


Here is how you can enable the auto troubleshooting process-

  • Firstly, from the central screen, go to settings and messages
  • Next, go to the help option, where you will find the troubleshooting option
  • Select the troubleshooting option and let your device find the problem

Once your device has identified the problem, take steps accordingly.
