Hisense TV Green Screen of Death: Fixes and Causes

Hisense is a popular smart TV brand that provides great picture quality and smart capabilities at an affordable price. However, some Hisense TV owners have reported issues with their screens displaying a green tint or entirely green picture. A green screen usually indicates a hardware or software problem with the TV. Here is an in-depth look at the possible causes and solutions for a Hisense smart TV displaying a green screen.

What Causes the Green Screen on Hisense Smart TVs?

There are a few possible culprits for the green screen issue on Hisense smart TVs:

  • Loose or Faulty Video Cable Connection
  • Outdated Firmware Version
  • GPU/Graphics Processing Unit Failure
  • LCD Panel Damage
  • Software Glitches or Corruption
  • IR/CEC Control Conflicts

How to Fix the Green Screen on a Hisense Smart TV

Here are the recommended steps to troubleshoot and resolve the green screen issue on a Hisense smart television:

Perform a Power Reset

DIFFERENT POWER OUTLET

The first step is to perform a simple power reset of your Hisense smart TV. This can clear any temporary glitches that may be causing the green screen:

  • Unplug the TV power cord from the electrical outlet.
  • Wait 1-2 minutes to allow any residual charge in the TV to dissipate.
  • Plug the TV power cord back into the wall outlet and turn the TV on to see if the green screen is still displaying.

This basic reset can resolve green screen issues caused by temporary software bugs or voltage fluctuations. Continue troubleshooting if the green screen persists.

Check Video Input Connections

HDMI Output

Faulty video input connections can also cause a Hisense TV to display green. Check that all cables connecting external devices like a cable box, game console, or Blu-ray player are properly and securely connected.

Loose HDMI or component video cables commonly cause green screen displays. Disconnect and re-seat all input cables to eliminate loose connections. Also, inspect cables for any damage that could impact signal transmission.

Swap input cables with spares to test if that resolves the green screen. Damaged cables can pass power but will have signal issues.

Reset External Connected Devices

Issues with your cable box, streaming stick, or other connected devices can also manifest as a green screen on your Hisense TV.

After checking the TV input connections, reset the power on all your connected devices by unplugging them from power, waiting 30 seconds, and plugging them back in.

Once the devices reboot and re-establish connection with the TV, check if the green screen is still showing. Resetting external hardware essentially performs a reboot and clears out any software errors.

Try Different Video Sources

Attempt viewing different video input sources like streaming apps, cable box channels, external media players, etc., to determine if the green screen persists across inputs.

This testing can confirm if the issue is isolated to a problem with a specific external device versus a general display problem with the Hisense TV.

For example, if the green screen only appears on your cable box input, the issue is with the box or its TV connection. If it also occurs on streaming apps, then it indicates a deeper issue within the TV.

Perform a Factory Reset on TV

If you still see the green screen on your Hisense TV across different video sources and devices, performing a factory reset on the television itself is the next logical troubleshooting step.

All Hisense smart TVs have an option in the system settings to reset the television back to its original factory state. This wipe will clear out any glitches, customizations, or faulty software that could be causing the green display problem.

To perform the reset, go to Settings > Device Preferences > Factory Reset and choose the full reset option. The TV will reboot and restore the factory default video settings, hopefully resolving any software issues at fault.

Check for Firmware Updates

Hisense TV System Update

Updating your Hisense smart TV firmware is an important maintenance step that can also specifically address problems like green screen errors.

Hisense periodically releases firmware updates to fix bugs, patch security risks, and improve performance. Always keep your Hisense TV firmware up to date for the best experience.

Go to Settings > Device Preferences > System Update to check for updates. The TV will automatically scan for any new firmware available to install. Major Hisense firmware updates can take 15-20 minutes to complete fully.

Adjust Picture Settings

Sometimes, a green screen issue can result from incorrect picture settings on your Hisense television. It’s worth examining the main video and picture options for any mode or configuration that could be leading to the green display output.

Under Settings > Picture, check that options like Picture Mode, Backlight, Brightness, Contrast, Color, Tint, and Sharpness are all set appropriately. For example, a very high Brightness or Contrast level could skew the color balance and produce a green tint.

Resetting the picture settings to default calibrations is recommended if you are unsure which customizations may affect color output to green.

Change HDMI Signal Settings

How the Hisense TV interprets the HDMI video signal can also impact the screen display colors. If the device is misreading the signal, it could lead to a green screen.

Under Settings > Device Preferences > Inputs, you can tweak settings for each HDMI input, such as HDMI Mode (1.4 vs 2.0), HDMI Deep Color (resolution rate), and Low Latency mode for lag reduction.

Adjusting these signal parameters can improve how video input is interpreted and resolve green color issues. Turning Low Latency mode off is particularly recommended.

Adjust HDR Settings

Disable HDR via Picture Mode

Today’s Hisense smart TVs are HDR-enabled, supporting advanced video formats like Dolby Vision, HDR10, and HLG. If your media sources use these technologies, the TV’s HDR settings must match the incoming high dynamic range signal.

Incorrect HDR configuration is a prime suspect for green screen problems. Under Settings > Picture > Advanced Picture, check settings like HDR Mode, HDMI HDR Format, HDR Brightness, and Peak Brightness.

You may need to toggle between HDR Modes or disable HDR entirely. Also, ensure the HDMI HDR Format matches the connected device (Dolby Vision, HDR10, etc).

Perform Panel Refresh

Hisense smart TVs contain an automated Panel Refresh process in the settings, which helps clear up panel glitches like green screens.

Go to Settings > Device Preferences > Panel Refresh to run a panel refresh. Choose from options like 15-minute quick refresh or 2-hour deep refresh, depending on the severity of the issue.

Panel Refresh will cycle the screen colors and discharge built-up voltage, which often remedies display problems. Green tints, in particular, can signal that excess voltage affects normal color balance.

Contact Hisense Support

If you still see the persistent green screen on your Hisense TV after trying all troubleshooting, it’s time to contact Hisense support. They can help diagnose if your television requires service or replacement under warranty.

When contacting Hisense Support, good information to have ready includes your TV model number, serial number, purchase date, and detailed description of the problem. This will help Hisense quickly determine the issue and solution for your green screen.

Replace Defective Parts

Once your defective Hisense TV components causing the green screen are diagnosed by a technician, replacing those parts is the critical fix needed.

Common parts that fail and lead to green screens include:

  • LCD Panel – displays images and colors
  • T-Con Board – processes the video signal
  • Main Board – houses critical processing chips
  • Power Supply Board – regulates voltage

Thankfully, these TV parts are modular and designed for replacement. Hisense technicians will have access to original manufacturer replacement parts ready for swap-in.

Parts repairs may occur either in-home or at a service depot, depending on the particular green screen failure. Expect 1-2 weeks repair turnaround once parts are ordered.
