Troubleshoot Hisense Smart TV – List of common problems and solutions

Find the problem you are facing and follow the troubleshooting steps provided:

1. Hisense Smart TV won’t turn on

If your Hisense Smart TV won’t turn on, the first thing is to check whether it has a power problem. The power supply may be faulty, and you need to fix it.

To do this, try plugging it into a different AC outlet.

You can fix this issue in different ways. Some of these methods include:

  • Unplug the TV from the power source or wall plug.
  • Wait for about 60 seconds.
  • After 60 seconds, plug it back in.

Unplugging and then plugging back the hardware will reset it. But if it does not solve the problem, consider the following fix.

  • Remove batteries from the remote control.
  • Hold down the power button for 15 seconds.
  • Reinsert the batteries in the remote control.
  • Use the remote control to turn on the TV.

If the above solves the problem, but it reoccurs a day or a week later, you will need to factory reset your Hisense Smart TV. Here is how:

  • Go to Settings.
  • Select System.
  • Choose Advanced System Settings.
  • Select Factory Reset.

The procedure above will reset all the settings on your TV and fix many other issues with it.

2. Hisense Smart TV screen keeps flickering

Flickering is one of the many screen problems you will encounter with the Hisense TV. You can try to fix it by turning the device OFF and ON.

But sometimes that may not happen, especially if an attached component on the device is at fault.

Also, unsecured cables and other features on your TV could be causing the issue. In other cases, it can occur as a result of incorrect TV settings, signal interferences, and electronic interference.

The following Hisense Smart TV troubleshooting steps can help you to identify the problem and fix it.

  • Check whether you have an interfering source nearby. Possible sources are appliances, electric tools, mobile phones, or even the fan. Try to move them away from the TV and see whether it helps correct the issue.
  • Insert the TV’s power plug into a different outlet to prevent interference.

Another troubleshooting step you can take is to turn off the Energy Saving feature of the TV. Here is how:

  • Using your remote control, go to Settings.
  • Select Picture.
  • Under Picture Mode, you will see the TV set to Energy Saving.
  • Select Picture Mode.
  • A list of seven options will display.

From this point, you can play around with any of those seven options to find one that will fix the flickering. Alternatively, perform a hard reset on your TV and see whether it offers a solution.

Also, some flickering problems occur because of a failed mainboard. You can fix it under warranty or contact a professional to do it for you. But if you have the know-how, consider replacing it.

3. Troubleshooting the brightness problem

Depending on the content you are watching, you may want to adjust your TV’s picture settings manually. On specific models, do the following:

  • Press the Settings button on your remote control.
  • A side menu will open up.
  • Press the right directional key to bring up the full menu options.
  • Select Picture Mode.

You can read this full guide on resetting Hisense TVs to know not just how to do it, but what will happen and how the reset can help you.

At Picture Mode, you need to adjust various settings to determine the right brightness level and fix the problem. But in general, you can optimize picture settings by ensuring you have the following values:

  • Colour Temperature – Low

Also, ensure that you set all other settings not listed above to OFF or Zero. For individual RGB color sub controls, let them have their default settings. Another thing to note is that most of these devices have preset brightness and color settings.

You can tweak the settings to how you want an image to appear on the screen. When you switch between presets, this can help you to control the brightness of your TV depending on the content you are watching.

If the above does not work, reset your TV to factory settings.

4. Hisense Smart TV blinking codes

Sometimes you may encounter a problem whereby the red LED on your Hisense Smart TV blinks several times. In most cases, the issue is not a software one, but rather a hardware one. But the first step of trying to fix it is to power-cycle your TV.

  • Press the power button on the device.
  • Unplug it from the power source.
  • Wait for 30 seconds
  • Plug the power cord and switch on the device.

Do these steps work? Well, if not, then you have a hardware problem.

  • If the red LED blinks six times, the issue could be the backlight or defunct mainboard, inverter boards, or power board.
  • If the red LED blinks four times, the problem could be the main logic board or inverter board wires.

You can start by contacting the Hisense Customer Support team for further troubleshooting and repair with a warranty. If you have an expired warranty, call a professional to have a look at it.

5. Hisense Smart TV screen went black

When your Hisense Smart TV goes black, you will not see any visible picture or background. But you will hear what is playing when you change a channel.

Here is how you can troubleshoot the problem.

  • Unplug the TV’s power cord.
  • Press and hold the power button for 20 seconds.
  • Let the TV remain unplugged for about two minutes.
  • Plug back the power cord.
  • Turn on the TV and try again.

Understand that the above procedure is necessary to confirm whether you can clear the problem with a simple reset. If that does not work, you are facing an internal issue with the hardware.

Your mainboard, power board, or LEDs could be defective. In that case, contact a professional or the Hisense customer support team to help you fix it.

6. Hisense Smart TV shows pictures with no sound

If you are getting this issue, you can fix it in two ways:

  • Check the volume settings to ensure it is not zero.
  • Check if you have set ON the Mute mode.

Once you troubleshoot the cause, fix it accordingly. If it does not work, reset your TV by doing a power cycle.

7. The TV turns on then off immediately

Sometimes the Hisense Smart TV turns on but doesn’t show pictures and then it turns off immediately. Such an issue can have different causes and fixes. You can do the following to try and fix it:

  • Take the batteries out of the remote control or hide them. A damaged remote control could be pressing keys without your knowledge. Once done, check whether it offers a solution.
  • Try doing a hard reset by unplugging the device from the mains supply. Wait for about 15 minutes then plug it back in. Once done, power on your TV and see whether it fixes the problem.

If the above does not work, the power supply could be the culprit. That can happen if there is an interim connection.

Check whether this is true and fix it. Also, check for loose plugs and try a different power cable or wall outlet.

8. Backlight not working

When the backlight is not working on your device, you will not see any image after powering it on. But you will hear sound when changing a channel. The problem is in your LED strips or the board that controls the LED strips.

Since it is a hardware issue, you will have to replace them from the back of your TV. You can have this replaced or fixed under warranty. If you do not have a warranty, contact a professional to help you with the repairs.

Conclusion

The best way of fixing a problem with your Hisense Smart TV is to troubleshoot it first. For example, you can fix most display issues on your Hisense Smart TV by simply turning the TV OFF and then ON.

Another option is to set the picture quality by adjusting the brightness, contrast, backlight, and color values of your device.

However, some of these problems can occur as a result of a hardware problem. In that case, contact the Hisense Customer Support team or hire a professional to do it for you.
