Is your Hisense TV suddenly showing a black screen, even though it sounds like it’s on and working? You’re not alone. The “black screen of death” is a common frustration among TV owners, especially for those with Hisense smart TVs.
This guide will walk you step-by-step through how to fix a Hisense TV black screen issue. By the end of this troubleshooting blog, you’ll know the causes, actionable solutions, and when it’s time to call in expert support.
Common Causes of the Hisense TV Black Screen
Before you can fix the problem, it helps to know what might be causing it. The black screen on Hisense TVs can originate from various sources, and identifying the root cause saves hours of trial and error.
Power Supply Issues – One of the leading reasons behind Hisense TVs displaying a black screen is a disrupted power supply. Faulty power outlets, surge protectors that have tripped, or aging TV power cords can prevent the TV from getting the electricity it needs, leaving you with a lifeless display.
Loose or Damaged Cables – HDMI and power cables sometimes come loose, are frayed, or damaged without notice. Even tightly plugged cables can develop faults inside.
A compromised cable connection can instantly cause the screen to go black by blocking signal transmission from the motherboard to the LED or LCD panel.
Backlight Failure – Modern LED TVs, including most Hisense models, use built-in LED backlights to illuminate the display. If the backlight fails, the screen will remain dark, even if audio continues and the TV turns on.
Firmware or Software Glitches – Smart TVs are essentially computers. If software crashes or the firmware is corrupt or outdated, it can freeze, glitch, or go dark.
Sometimes, a simple update is all it takes to bring your Hisense TV back to life.
Mainboard or Hardware Malfunctions – A more serious, hardware-related problem may involve the mainboard or T-Con board inside the TV. This might require professional repair, but some tech-savvy users attempt board replacement with success.
Sleep Timer or Power-Saving Mode – Sometimes, settings like the Sleep Timer or Eco Mode power down your TV’s display to save energy. These features, if accidentally activated, can also cause confusion.
Note: Understanding the causes can reduce frustration and prevent you from paying for unnecessary repairs.
Quick First Steps to Diagnose Your Hisense TV
Before jumping into technical fixes, let’s determine the nature of your Hisense TV black screen problem.
Check for Power and Connection
- Confirm the TV is plugged into a working outlet by plugging in another device.
- Ensure the power indicator light on your Hisense TV is on.
- Try switching the input source (HDMI1, HDMI2, AV) in case the current source has lost signal.
Use the Flashlight Test
A clever and safe way to check for backlight failure is the flashlight test:
- Power on your TV.
- Shine a flashlight directly onto the TV screen from a close distance.
- Look for faint images or user interface outlines.
If you see shapes or menus, your TV’s backlight may have failed, but the rest of the TV is working.
Listen for Audio
Volume up on the remote or via the TV’s manual controls. If you can hear sound, but see no image, it often points to a backlight, screen, or mainboard issue.
Restart or Power Cycle
Unplug your Hisense TV from the wall for 3-5 minutes, then plug it back in. This resets the system and, surprisingly often, resolves temporary glitches that cause a black screen.
If these diagnosis steps haven’t resolved the issue, move on to more in-depth troubleshooting.
Step-by-Step Guide for a Hisense TV Black Screen
Understanding the cause narrows down your troubleshooting. Let’s walk through proven solutions, with practical advice for every skill level.
1. Inspect Power Cables and Outlet
Begin by unplugging the TV, inspecting the power cord for damage, and trying a different outlet. If your power strip has a reset button, press it to ensure full power is restored. If you need a replacement, reliable universal power cords like this one can be a quick fix.
2. Check and Replace HDMI or Input Cables
Unplug and replug all cables, making sure they’re seated firmly. If you have spare HDMI or AV cables, try swapping them in. Faulty cables are a common culprit for display issues.
3. Hard Reset Your Hisense TV
A hard reset can clear temporary software glitches. To hard reset most Hisense models:
- Unplug the TV from the power source.
- Hold down the TV’s physical power button (not the remote) for 30 seconds.
- Plug the TV back in and turn it on.
This process drains residual power and forces a fresh boot sequence.
4. Test With a Different Input Device
Connect another device (like a game console, Blu-ray player, or streaming stick) using a known-good HDMI cable. Set the TV to the correct input source.
If the new device displays, the issue is likely with your previous device, cable, or input source – not the TV itself.
5. Adjust TV Screen Settings
Go to your TV’s settings (if visible) and look for Eco/Energy Saving Mode and Sleep Timer settings under “System” or “Power” menus. Disable them to prevent unwanted shut-offs.
6. Update Firmware and Apps
Hisense regularly releases updates to fix bugs. If you can access the menu:
- Go to Settings > Support > System Update.
- Install available updates and restart the TV.
For those unable to see any screen, check the Hisense website for USB firmware update options.
7. Perform a Factory Reset
If your screen turns on sporadically or for a few seconds, there’s a chance a factory reset can help:
- Go to Settings > Device Preferences > Reset.
- Confirm and follow the on-screen instructions.
A factory reset can clear stubborn software issues, but it will erase your apps and preferences.
8. Examine for Backlight Failure
If your flashlight test earlier revealed faint images, your backlight may be out. Replacing LED backlights is possible for experienced DIYers (see this backlight replacement kit), but can be tricky.
Alternatively, contact a professional repair shop or Hisense support for service.
9. Inspect the Mainboard and T-Con Board
More advanced users can open up the back panel to visually check for burnt-out components or bulging capacitors on the mainboard. If you spot such damage, replacing the board may fix the issue.
Exact replacement steps will depend on your Hisense model, and sourcing the right parts is crucial.
Safety Reminder: Only open up your TV if you’re comfortable working with electronics.

Advanced Fixes and When to Call a Professional
While most black screen issues are resolved by the steps above, some problems demand technical expertise.
Replacing Backlight Strips
For LED TVs, failed backlights often mean replacing the internal LED strips. This involves removing the back cover, disconnecting the mainboard, and carefully installing new strips. Not for beginners—but accessible for those comfortable with YouTube tutorials and steady hands.
Tip: If your Hisense TV is under warranty, always contact support before opening up the TV.
Replacing the T-Con Board
The Timing Control (T-Con) board is a small circuit that drives the TV display. Symptoms of a failing T-Con include flickering displays, lines, or black screens. Replacements are available online, but compatibility is key. Always match the part number to your TV model.

Preventing the Black Screen Issue on Hisense TV
A bit of preventative care keeps your TV working for years to come. Here’s how to reduce the risk of the infamous black screen.
Use Stable Power – Surge protectors safeguard your TV from electrical surges that damage internal circuits. Unplugging your TV during lightning storms adds another layer of safety.
Keep Software Up to Date – Regularly check for system and app updates. Keeping your software current reduces frozen screens and blackouts caused by bugs.
Handle Cables with Care – When repositioning your TV or home theater system, avoid yanking or sharply bending cables. Replace any that show signs of wear.
Avoid Overheating – Ensure that your TV’s air vents are clear of dust and there’s enough room around the TV for proper airflow. Overheating can accelerate hardware and backlight failures.
Adjust Eco/Sleep Settings – Disable or customise any energy-saving settings so your TV display doesn’t inadvertently shut off mid-movie or during a big game.

FAQs On Hisense TV Black Screen Issues
Why did my Hisense TV screen suddenly go black, but the sound still works?
This often indicates a backlight failure or a bad cable. Since the sound comes from a separate circuit, it can work even when the LED display has failed. Try the flashlight test mentioned earlier.
If you see dim images, it’s almost always a backlight issue. If not, try different input sources and cables before moving to internal hardware diagnosis.
How do I reset my Hisense TV when the screen is black?
First, unplug the TV for several minutes to perform a power cycle. If you have access to a reset button (often located on the lower side or back of the TV), press and hold it for 15 seconds.
You can also attempt a blind reset by pressing MENU, DOWN, DOWN, DOWN, OK (for most models) on your remote, based on the Hisense on-screen menu order.
Is a black screen on my Hisense TV a sign of a broken display panel?
Not always. Many black screen issues are due to software glitches, loose cables, or a failed backlight, not necessarily a broken panel. Broken panels are rare unless caused by impact.
Does a software update fix the black screen problem?
Yes, in some cases. Firmware bugs can cause black screens, especially in smart TVs. If your menu is visible or TV intermittently shows the picture, update your firmware via the TV’s settings menu or with a USB stick from the official Hisense support website.
Should I replace my Hisense TV or repair it?
If your TV is within warranty or the cost of repair is less than 30-40% of a new unit’s price, repair is often the better route. If you’re facing repeated failures, the TV is several years old, or replacement parts aren’t readily available, consider upgrading to a newer, more reliable model.
Where can I buy replacement parts for my Hisense TV?
Amazon is a top source for replacement power cords, HDMI cables, backlight kits, and mainboards. Ensure you know your Hisense model number and part details before purchasing:
You can also check authorized electronics parts suppliers for T-Con or mainboard replacements.
My TV works for a few minutes, then the screen goes black. What’s wrong?
This symptom can point to overheating, a failing power supply, or impending backlight failure. Ensure your TV has adequate ventilation, update your software, and consider having the power supply tested by a professional.
What can I do if none of these solutions work?
If you’ve worked through all troubleshooting steps and your screen remains black, or if you’re uncomfortable attempting further repairs yourself, it’s time to reach out to a professional repair technician or contact Hisense customer service.
