How can you fix a black screen on Hisense TV?

Encountering the dreaded black screen of death on your TV can be a scary experience. However, in most cases, the underlying issue is one that you can easily troubleshoot and fix yourself.

Below is a step-by-step guide on this issue, covering everything from what causes the black screen to how to troubleshoot and fix your TV.

What causes a black screen on Hisense TV?

Several issues can cause a black screen on your Hisense TV. The top ones include:

  • Your TV is not turned on.
  • Your TV is stuck in standby mode.
  • Defective power cord, surge protector, extension cable, or electrical outlet
  • Overheating
  • A problem with the TV input source
  • Bugs and software glitches
  • Outdated firmware
  • Damaged TV backlights
  • Problems with other internal hardware components

Basic troubleshooting guide

To fix a black screen on your TV, try the following simple troubleshooting steps:

  • Ensure that your TV is turned on.
  • Check that your remote control is working (if using it to turn on your TV). If not, replace the batteries and try again.
  • Check that your power cord is properly connected to the TV and the electrical outlet.
  • Check that the HDMI cable or other input source cables are properly connected.
  • Check that you have selected an input source on your TV.

If none of these fixes work, try the advanced solutions below:

1. Check on the power supply

Your Hisense TV might be connected to the power source but still experience power supply issues.

Power supply problems can occur if the electrical outlet, the surge protector, the extension cable, or the TV power cord are defective. These issues can lead to an unstable voltage supply, causing your Hisense TV screen to turn black.

To fix the problem, check that your electrical outlet, power cord, surge protector, and extension cables are not defective. Next, connect your TV to a different power outlet and disconnect (or replace) the surge protector and extension cable.

2. Power cycle your TV

Power cycling can help to clear a black screen on Hisense TV caused by issues like a stuck standby mode, software glitches, and bugs.

To power cycle your TV:

  • Unplug your TV from the electrical outlet.
  • Leave it to rest for a few minutes (although you can wait up to an hour or overnight if you are not in a hurry).
  • Plug the TV back in, then turn it on.

If you are dealing with a minor problem, the issue will be resolved, and the black screen will disappear.

3. Let your TV cool down

Your Hisense TV screen can turn black due to overheating. When this happens, the best thing to do is to let your TV cool down.

Therefore, you should immediately disconnect the TV from the power source and let it be for a few minutes (or up to an hour and more).

Besides cooling down, you can prevent overheating by:

  • Ensuring your TV’s air vents are properly ventilated.
  • Moving your TV away from direct sunlight or heat-emitting electrical devices.
  • Cleaning your TV’s air vents with compressed air to remove built-up dust.

Unfortunately, in some cases, the overheating can be caused by faulty temperature sensors or the cooling system. Therefore, if the above solutions are not working, you should take your TV to an authorized service center for repairs.

4. Check your input sources

If your TV shows a black screen when it is turned on, you may be dealing with a faulty input source. This can occur if the input source cables or ports are damaged or the input source device has malfunctioned.

To fix the issue, examine the input cables (HDMI, RCA) to ensure they are not damaged. Next, check that the input source device, for example, the Roku streaming device, set-top box, and firestick, is working correctly.

Lastly, try switching to a different input source device to see if your Hisense TV will start displaying images and sound.

5. Update the TV firmware

A firmware issue can cause your TV to glitch, rendering it unusable. When this happens, you might find that your Hisense TV turns on but has no picture or sound.

Fortunately, updating the firmware can fix the problem and clear the black screen.

With the black screen on, you might be unable to update your Hisense TV’s firmware directly on the internet. However, you can update the firmware via USB using the steps below.

  • Go to your TV’s back panel and note down the serial number.
  • Go to the Hisense Firmware download website, enter your TV’s serial number, and search for available updates.
  • Download the firmware and copy it to an empty (formatted) USB drive.
  • Unplug the TV from the power source and leave it for about five minutes.
  • Insert the USB (with the firmware update) into your TV’s USB port
  • Plug the TV back into an electrical outlet.
  • Press and hold the power button on your remote control while pointing it at the TV.

The firmware in the USB drive should start installing, after which your TV will restart. 

6. Repair your Hisense TV backlights

Are you experiencing a black screen on Hisense tv with sound? Your TV backlights might be faulty.

To be completely sure that you are dealing with a backlight issue, you can perform a flashlight test by following the steps below:

  • Turn the TV on in a completely dark room.
  • Take a flashlight and direct the light towards the TV screen.
  • If you can see the Hisense logo or images, this is a sign that your backlights are faulty.

The only way to fix faulty backlights is to repair or replace them. You can do this yourself if you have the technical know-how, but if not, you should take your TV to an authorized service center.

7. Factory reset your Hisense TV

Factory resetting is another top solution that can help fix the black screen of death on a TV. Unfortunately, the factory reset option via your TV settings will be unavailable.

However, you can factory reset your Hisense TV using the hard reset button. To do this:

  • Locate the “reset” button on the back panel of your Hisense TV. Note: in some TV models, this might be a pinhole button.
  • Press and hold the reset button for about 15 seconds while the TV is turned on.

The factory reset will initiate, completely wiping all the settings on your TV. Once the process is completed, you can turn the TV on and set it up afresh.

Have your say

Are you still experiencing a black screen on Hisense TV even after attempting the solutions above? Your TV might have suffered major software or hardware issues.

Therefore, you should contact the Hisense Customer Centre for additional troubleshooting. Alternatively, you can take your TV to an authorized service center for repairs or look into buying a new Hisense TV.
