2. Check the HDMI Port

Next experiment by connecting your device to different HDMI ports on your Hisense TV. If you notice that one particular port is causing issues, it could be indicative of a faulty port. In such cases, it’s essential to investigate further.

Take a closer look at the HDMI ports on your Hisense TV for any signs of physical damage, such as bent pins or accumulated debris. These issues might hinder the proper functioning of the port and lead to connectivity problems.

3. Assess the Input Source

The next step is to confirm that you’ve selected the right HDMI input corresponding to the port where your device is connected.

Hisense TVs often have multiple HDMI ports, and it’s surprisingly easy to accidentally choose the wrong one. This innocent mistake can result in that frustrating “no signal” message on your screen.

Let’s say you’re connecting a modern device that uses HDMI 2.0. Now, in this case, you’d want to confirm that you’ve selected the corresponding HDMI input labeled “HDMI 2” or something similar.

Selecting, for instance, “HDMI 1” when your device is plugged into “HDMI 2” might lead to the dreaded “no signal” scenario.

Take that extra moment to ensure your Hisense TV is tuned into the precise HDMI input that aligns with the capabilities of your connected device, whether it’s HDMI 1.4, HDMI 2.0, or another version.

This simple check can make a world of difference in resolving HDMI-related issues.

4. Test with Another Device

Consider this step as a diagnostic test for your HDMI puzzle. Take the HDMI cable that’s causing the hiccup and use it to connect a different device, perhaps another TV or monitor. This step serves as a crucial litmus test.

If the issue persists on the alternative device, it’s a sign that the problem may lie within the Hisense TV itself. This could be due to a faulty HDMI port or even a glitch in the TV’s software.

On the flip side, if the HDMI connection works seamlessly with the alternative device, it’s a strong indication that the original device or its settings might be the culprit.

5. Use the Power Cycle Method

Next, consider power cycling your devices. This process serves as a reset mechanism, specifically designed to address temporary software glitches that may be causing the issue.

Follow these steps to perform a power cycle:

  • Turn off the TV by unplugging the power cord from the wall outlet.
  • Wait for 30 seconds.
  • Flip the TV’s power switch back on after a brief pause for a reset.
  • If the HDMI problem persists, opt for a more direct reset approach.
  • Turn off the TV once again.
  • Unplug the HDMI cable from the back of the TV.
  • Power on the TV without the HDMI cable connected.
  • Once the TV is operational, reinsert the HDMI cable.

This step-by-step reset can help eliminate stubborn glitches in the HDMI connection, restoring smooth streaming functionality.

6. Verify Compatibility

It’s crucial to ensure that both devices speak the same language in terms of HDMI specifications. Take a moment to confirm the compatibility between your device and the Hisense TV.

For instance, if you’re attempting to connect a cutting-edge HDMI 2.1 device to an older TV equipped with HDMI 1.4 ports, you might encounter compatibility issues that could be the root cause of the HDMI not working problem.

To tackle this, refer to the manuals accompanying your device and the Hisense TV. These manuals typically provide detailed information about supported HDMI standards.

Check for any specific requirements or limitations, and ensure that the HDMI standards of your device align with the capabilities of your TV.

7. Update Software

Visit the Hisense website to check for software updates for your TV. Follow the instructions provided by the manufacturer to update the TV’s firmware.

Software updates often address bugs and improve overall system stability, potentially resolving HDMI-related issues.

Ensure that your Smart Hisense TV is set up for Over-the-Air (OTA) firmware updates by following these steps:

  • First, press the Home button on your remote.
  • Next, navigate to the settings represented by the “cog” icon, then proceed to Support and System Update.
  • Confirm that the Auto Firmware Upgrade option is activated.

In case your TV lacks OTA support, you can still check for updates with the following steps:

  • Press the Home button on your remote, and click the cog icon >  All >  About > System Update.

After updating your TV, check if the issue is resolved.

8. Perform a Factory Reset

If all else fails, consider performing a factory reset on your Hisense TV. Keep in mind that this step erases all personalized settings, returning the TV to its original state.

Use this step as a last resort when other troubleshooting methods have not resolved the HDMI issue.

To perform a factory reset:

  1. Press the Home button on your remote.
  2. Then the “cog” icon > Device Preferences > Reset > Erase everything.

After this your TV will restart, having reset to default factory settings.

However, if you fail to resolve the issue even after trying all the above troubleshooting steps, then reach out to Hisense customer service to assist you.
