Immediate action is required to resolve the black screen issue and prevent further complications with your Hisense TV. Below, we outline the troubleshooting methods to resolve this problem quickly.
Common Causes of a Black Screen on Hisense Smart TV
A black screen on a Hisense Smart TV is a complex issue that can arise from various technical faults and software problems. Here are some common factors that may cause this issue:
- Power fluctuations
- Defective HDMI cables or ports
- Outdated TV firmware or minor bugs
- Damaged backlights
- Hardware issues
Different Methods to Troubleshoot Hisense TV Black Screen of Death Issue
This guide outlines various troubleshooting steps to help you fix the black screen issue on Hisense Smart TVs.
Check the Power Supply on Hisense TV
- Low voltage at home can sometimes cause a black screen on your Hisense TV. The TV requires a consistent flow of electric current, and if this flow is disrupted, a black screen may occur. Check for any voltage issues in your home.
- Defective surge protectors or extension cords might not supply enough current to the TV. Avoid using these with your Hisense TV.
- If the voltage is stable, there could be a problem with your power socket. Try connecting the TV power cord to a different outlet after waiting for 30-60 seconds to see if the black screen issue is resolved.
- A defective power cable can also lead to an insufficient power supply, causing a black screen. Inspect the cable for damage and replace it if necessary.
- In some cases, the issue might be with the remote control. If you can’t turn on the TV and only see a black screen with a red light, try using the power button on the Hisense TV panel instead.
Inspect HDMI Cables and Ports
- If your streaming device or gaming console shows a black screen on your Hisense TV, the issue might lie with the HDMI cable or port.
- Check the HDMI ports for any damage and try plugging the HDMI cable into a different port on the Hisense TV. Ensure the HDMI cables are securely connected to the TV.
- Inspect the HDMI cable for defects. If the cable is damaged, consider purchasing a new one.
Verify TV Input Settings
- Incorrect input settings can also cause black screen issues. For example, if you connected a PS5 via HDMI but set the input to another HDMI, the TV will display a black screen.
- To fix this, change the input on your Hisense TV to the correct HDMI setting.
- Occasionally, the issue might be with the external streaming device. Restart or update the device and check if the black screen issue is resolved. If not, proceed to the next troubleshooting step.
Restart Hisense Smart TV
To address the black screen issue on your Hisense TV, whether there is sound or not, try restarting the device. Restarting can clear unwanted bugs, enhance performance, and resolve various issues.
- Turn off your Hisense TV and unplug the power cables.
- Let the TV sit idle for 2-3 minutes.
- Reconnect the cables and turn on your Hisense Smart TV.
Update Hisense Smart TV
A software glitch in the TV firmware can sometimes cause the screen to go black. You can fix the issue by updating the Hisense TV to the latest firmware version. If the screen is partially black, navigate to the Settings menu and update your Hisense Smart TV.
Factory Reset Hisense TV
For a completely black screen, a factory reset may be necessary to restore the device to its default settings. Use the reset button on the back of the TV to perform this reset without accessing the settings menu.
- Press and hold the reset button on your Hisense TV or other models for 30 seconds.
- Complete the reset process without a remote.
- After resetting, check if the black screen issue is resolved.
If the screen remains blank with no picture, proceed to the next troubleshooting step.
Replace or Repair the Hisense TV Backlights
If your Hisense TV is dark on one side, the backlight in that area may be damaged. Sometimes, all backlights might fail due to power supply issues, leading to a completely black screen.
Backlights are crucial for displaying images on your Hisense TV. If your screen is entirely black, replacing the LED backlights is necessary. To check if the backlight is the issue:
- Play any content on your Hisense TV.
- Shine a flashlight close to the TV screen.
- Move the light across the screen and see if you can detect any images.
If you see images under the flashlight, the backlight is the problem. You can call a technician to replace the backlight, which typically costs between $100 and $500.
Check for Other Hardware Issues
If the black screen persists, there may be a problem with the T-CON board, a key component for creating images on the TV display. You can call a Hisense technician or replace it yourself by carefully opening the back panel.
Additionally, inspect other hardware components, like the power board. Replacing or repairing these parts can resolve the black screen issue.
