How to Fix Hisense TV Black Screen Issue [2025 Guide]

A black screen on your Hisense TV can be annoying especially when you’re all set to watch your favorite show, a big game, or a movie. Sometimes the screen goes completely black, sometimes it flickers, and other times you might still hear the sound but see no picture. It happens more often than you might think. The good news? In most cases, you don’t need to replace your TV. Many Hisense TV black screen problems can be fixed at home with a few simple steps. In this guide, we’ll walk through the most common causes, practical fixes you can try yourself, and when it might be time to get professional help.

Common Causes of Hisense TV Black Screen

A black screen can be frustrating, but it usually points to a few common issues. Here are the most likely causes:

• Loose or damaged cables: If the HDMI or power cables aren’t secure or are damaged, the signal may cut out.

• Backlight problems: The TV may still be on, but if the backlight fails, the screen will look completely black.

• Software glitches: Outdated firmware or a temporary software bug can interfere with the display.

• Power supply issues: A faulty power board or unstable power connection can cause the screen to go dark.

• Wrong input source: Sometimes the TV is simply set to the wrong input channel.

• Hardware failure: Internal parts like the mainboard, T-CON board, or screen panel may be defective.

• Overheating: If the TV runs for long hours without proper ventilation, it can overheat and shut down the display.

Quick Fixes to Try First

Before jumping into detailed fixes, try these quick checks first:

• Make sure all cables (HDMI, power, etc.) are plugged in securely.

• Test a different HDMI cable or port.

• Double-check that your TV is set to the right input/source.

• Unplug the TV from power for 5–10 minutes, then plug it back in.

• Try turning the TV on using the button on the TV itself instead of the remote.

These simple steps often solve small glitches. If your screen is still black after this, move on to the more advanced troubleshooting steps below.

Step-by-Step Troubleshooting Guide

1. Power Cycle Your TV

Unplug your Hisense TV from the wall and leave it off for about 10 minutes. Then plug it back in and turn it on. This clears the TV’s memory and often fixes small software glitches.

2. Inspect and Replace HDMI/Power Cables

Take a close look at your HDMI and power cables. If you see any frayed, bent, or loose ones, replace them. Try plugging the HDMI cable into a different port and make sure everything is firmly connected.

3. Check for Backlight Issues

Turn the TV on and shine a flashlight close to the screen. If you can see faint images, it means the backlight isn’t working and may need repair or replacement.

4. Update TV Firmware

Go to Settings > System > About > System Update (the wording might vary depending on your model). Installing the latest firmware can fix bugs that cause black screen issues.

5. Factory Reset the TV

If problems continue, perform a factory reset. Go to Settings > Device Preferences > Reset. Keep in mind this will erase all your apps and custom settings.

6. Test With Another Device

Connect something else like a streaming stick, gaming console, or Blu-ray player to see if the problem is with the TV or the device you were originally using.

7. Inspect Power Supply Board

If the TV won’t turn on at all, the power supply board might be faulty. This usually requires professional repair.

8. Contact Hisense Support

If nothing works, reach out to Hisense support or a certified technician. If your TV is still under warranty, hardware repairs might be covered.

Preventive Tips to Avoid Black Screen Problems

• Use good-quality HDMI and power cables for a stable connection.

• Keep your TV’s software up to date.

• Make sure your TV has enough airflow around it to avoid overheating.

• Plug it into a surge protector to protect against sudden power spikes.

• Don’t leave the TV running for hours on end when you’re not using it.

Hisense TV Black Screen on Roku and Android Models

Hisense makes TVs that run on different platforms, like Roku TV and Android TV. Both can run into black screen problems, but the reasons are usually a little different.

• Roku Models: With Roku TVs, the issue often comes from HDMI handshake problems or firmware bugs. A simple restart or factory reset usually clears things up.
• Android Models: On Android TVs, black screens are more likely tied to system crashes or app conflicts. Updating your apps and clearing the cache often fixes the problem.

Advanced Fixes for Persistent Black Screen
