This article will explore some common causes of the Hisense TV black screen and provide guidance on how to address these issues effectively without the need for professional assistance.

Troubleshooting Hisense TV Black Screen
Having a black screen on your Hisense TV can be frustrating, but with the right troubleshooting steps, you can likely fix it and get back to enjoying your favorite shows and movies. In this section, we will discuss common methods to troubleshoot and fix a Hisense TV black screen issue.
Power Cycling the TV
A common and straightforward fix for the Hisense TV black screen issue is power cycling the TV. This involves turning off the television, waiting for 15-30 seconds, and then turning it back on. Power cycling resets the internal circuitry of the TV and can resolve hardware issues that might be causing the screen to turn black1.
Checking HDMI Connections
Another possible reason for the black screen issue might be due to loose or faulty HDMI connections. Make sure to check all HDMI connections by unplugging them and then plugging them back in securely2. If you’re still experiencing the black screen, try using different HDMI cables or ports on your TV to rule out any issues with the cable or port itself.
Backlight Test
If your Hisense TV still shows a black screen after trying the above methods, it’s worth checking if the backlight is working. To do this, shine a flashlight on the screen while it’s on; if you can see some images or faint content, the backlight might be faulty. In this case, you might need to consult a professional technician for further assistance.
Resetting the TV
Resetting your Hisense TV to its factory settings might help resolve the black screen issue. However, it’s essential to note that this process will erase any custom settings, so proceed with caution. To reset your TV, navigate to the settings menu, find the reset option, and follow the on-screen instructions. If the black screen persists after the reset, there might be a more severe issue at hand.
Updating Firmware
Lastly, it’s essential to keep your Hisense TV’s firmware updated, as outdated firmware can occasionally cause the black screen issue. Most Hisense TVs have an automatic update feature, but you can manually update the firmware if needed. To do this, visit Hisense’s official website, find your specific TV model, and download the latest firmware version. Then, follow the instructions provided to update your TV’s firmware.
By following these steps, you should be able to troubleshoot and resolve most Hisense TV black screen issues. If the problem persists, it’s recommended to get in touch with Hisense customer support or consult a professional technician for specialized advice.
Hardware Issues and Solutions
T-CON Board
A common issue with Hisense TV black screens can be related to the T-CON board. This board is responsible for processing the image signal from the main board to the screen. A faulty T-CON board can result in a black screen or distorted images. To fix this issue, ensure the T-CON board is properly connected, and if necessary, replace it with a new board.
Power Board
The Power Board supplies power to the entire TV, so issues with this component can cause your Hisense TV screen to go black. Check the power source, and ensure that the power board is receiving sufficient power. If the TV still doesn’t turn on, you may need to replace the power board.
Main Board
The Main Board is vital for controlling the TV’s functions and processing signals. A malfunctioning main board can lead to a black screen on your Hisense TV. First, try resetting the TV by unplugging it for a few minutes and then plug it back in. If the problem persists, consider replacing the main board.
LED Backlights
LED backlights illuminate the TV screen, and if they fail, the screen may appear black even if the TV is on. It is usually difficult to determine if the issue is with the LED backlights without professional assistance. Nonetheless, if other hardware components are functional, you may need to replace the LED backlights to fix the black screen issue.
Ribbon Cables and Connectors
Loose or damaged ribbon cables and connectors can cause a Hisense TV black screen. These cables connect the main board to the T-CON board and the LED backlights. Check for any loose connections and ensure that the cables are in good condition. Replace any damaged cables to resolve the problem.
Checking Cables and Ports
When dealing with a black screen issue on your Hisense TV, it is crucial to inspect all cables and ports, ensuring their proper functioning and connection. This section will guide you through examining HDMI cables, power cords, and outlet connections.
Inspecting HDMI Cables
Faulty HDMI cables can often cause black screens. Start by disconnecting both ends of the HDMI cable from your Hisense TV and the video source (such as a gaming console or streaming device), and if necessary, replace the HDMI cables with new ones. Ensure that the HDMI cable is fully plugged into the correct HDMI port on your TV and video source. Check the HDMI type above the HDMI port you are using and, using your Hisense TV remote, search for the corresponding input for your HDMI cable as mentioned in these steps.
Examining Power Cords and Outlets
The power cord connection also plays a vital role in resolving black screen issues. Inspect the power cord, switch, and cable, unplugging it and waiting 15-30 seconds before plugging it back in and turning the TV on as described here. If the issue persists, consider replacing the power cord with a durable option such as the Cable Matters C7 power cord.
Next, examine the power outlet for any signs of damage or malfunction. Test the outlet by plugging in a different device to ensure it is working correctly. If it isn’t, call an electrician to correct the issue before retesting your TV.
Ensuring Proper Connection
Lastly, verify that all other input cables such as audio, antenna, or additional video connections on the TV are properly seated and functioning. Any loose or damaged connections may contribute to the black screen problem. Secure all connections as necessary, ensuring a tight fit, and keep an eye out for any worn or frayed cords.
By following these procedures to inspect your HDMI cables, power cords, and ports, you should be well-equipped to identify and resolve any black screen issues on your Hisense TV.

To resolve such issues, check for available software updates for your HiSense TV or Roku device, and apply them as necessary. You can also try restarting the devices by unplugging their power cords for 60 seconds, then plugging them back in.
Apps and Streaming Services

- Look for subtle signs of an image or faint lines on the screen.
If you can see an image with the flashlight, it’s likely that the backlight has failed. Replacing the failed backlight should resolve the black screen issue.
Contacting Manufacturer Support
If the previous troubleshooting methods do not solve your Hisense TV black screen problem, it’s time to contact the manufacturer for further assistance. Hisense offers customer support through phone, email, and live chat. Make sure to provide them with a detailed description of the issue, the troubleshooting steps you’ve taken, and your TV’s model number. They should be able to guide you in resolving the issue or, if necessary, arrange for a repair or replacement.
