Troubleshooting Hisense TV Common Problems

Last Updated on May 8, 2023 by Tim Wells

Hisense TVs are awesome! Hisense has some of the best smart TVs around, from Laser TVs to ULED and UHD. But, as impressive as they are, the TVs aren’t perfect, and things do go wrong.

Some of these problems are common, and it’s easy to fix them. However, some issues are severe and require a professional. If you’ve tried everything on this list and our Hisense TV still isn’t working, it’s time to make the call and get a Hisense TV expert to fix yours.

Here’s a list of Hisense TV troubleshooting problems common among the Hisense brand and TVs in general.

Hisense TV Troubleshooting for When Things Go Wrong

When something goes wrong with your TV, your first reaction might be to make a phone call to your local repairman. However, it’s better to try and fix the problem yourself. 

If it’s something that you can fix easily and quickly, then you don’t have to wait for someone to take a look at it, and you’ll save lots of money in the process.

Here’s a list of some of the most common Hisense TV troubleshooting tips.

1. Your Hisense TV Won’t Turn On

Double-check your power. The wiring in some houses can be faulty, and sometimes outlets act up. Make sure you don’t have a defective fuse by trying to plug your television into another outlet. Also, make sure your remote is functioning. If you haven’t changed the batteries in a while, it might be best to do that first.

  • Unplug your Hisense TV for 30-60 seconds and then plug it back in
  • Double-check that your remote is functional by changing the batteries

If this solves your problem, then great! However, if it continues to happen sporadically throughout the next couple of weeks, then you should reset your TV to factory settings.

Resetting your Hisense TV:

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

A hard reset will fix many problems by reverting all your settings on your television to what they were before you took it home. However, if it continues to periodically not turn on then, you’ll need to get it looked at by a professional.

2. Hisense TV Keeps Flickering

Flickering TV screens are so annoying. They keep you from fully enjoying and immersing yourself in your favorite shows and movies. There are several ways you can combat flickering TVs, including:

  • Double-checking all your cables are secured
  • Plugging in your TV to a different outlet
  • Turning your television off and on again
  • Ensuring your cable company isn’t experiencing technical problems
  • Making sure there are no other electronic or plugged in devices near your TV
  • Turning off Energy Saving Mode in Picture under the Settings menu
  • Hard reset your TV

Unsecured cables or a fan being too close to your Hisense TV could be causing the picture to jump. If you’ve tried all of these and none of them are working, it might be a failed mainboard. If you’re under warranty, give the company a call. Otherwise, hire a professional to look at it or change it yourself.

3. Brightness Issues and Fixing Them

If you feel that your TV is too bright or too dark, then it might be time to go and make sure that all your settings are correctly adjusted. First, pull up the Picture menu by bringing up Settings and then pushing right.

The basic parameters of Picture mode are as follows:

  • Picture Mode: Theatre Night
  • Backlight: 52
  • Brightness: 51
  • Color: 49
  • Color Space: Auto
  • Contrast: 47
  • Color Temperature: Low
  • Gamma: 2
  • HDMI 2.0 format: Enhanced
  • Local Dimming: High
  • Sharpness: 0
  • Tint: 0

The HDMI Dynamic Range can’t be adjusted, so it’s fine where it is. All other settings should be off or at zero. The manual RGB controls should be set to default unless you like a violet or orange tint.

If that doesn’t seem to help, try the tried and true method of resetting your TV to factory settings. After that, it’s a hardware problem and needs to be looked at by a professional.

4. Hisense Smart TV Red LED Indicator Blinking

Sometimes your TV indicator light will blink at an odd interval. The blinking is typically done in sets of four or six and tends to indicate a hardware problem, which is something that you can’t fix by yourself.

Before calling your TV professional repairman, you might want to try a soft reset. Turn off your television, unplug it for 30 seconds, and plug it back in to see if that does anything. If not, then time to make the call to the repairman or the Hisense customer support team if you’re still under warranty.

Four blinks mean issues with:

  • Main logic board
  • Inverter board wires

Six blinks mean issues with:

  • Backlight
  • Mainboard
  • Inverter boards
  • Powerboard

It’s best to get this checked out even if your TV is working fine. An overheated board can cause issues to other parts of your TV, turning a reasonably inexpensive bill into having to buy a whole new television.

5. Your Screen Went Black

You’ll be able to hear what’s playing on your TV, but the screen won’t show anything. Your remote will also still work, and you can listen to the sound when you change channels.

A simple reset, not a hard reset, should fix the problem if it’s a software issue. Here’s what you do:

  • Unplug your Hisense TV
  • While it’s unplugged, hold down the power button on the TV itself for 20 seconds
  • Leave your television unplugged for a couple of minutes – at least two
  • Plugin your TV
  • Turn it back on

That should fix the problem. If it doesn’t, you have a hardware issue. You need to contact Hisense customer service if you have a warranty or hire a maintenance specialist if you don’t. There is something wrong with either the LEDs, the power board, or the mainboard.

6. Backlight not Working

A cousin to the screen went black if you turn on your TV and you don’t get a picture, but you do get sound, then your LED strip or the connection to your LED strip is broken, and so your backlight isn’t working.

The backlight is what allows a TV to light up, so it’s something that needs fixing right away. However, if you’re under warranty, then you should be able to replace it through the Hisense customer support team with little issue.

If you aren’t under warranty, then you’ll need a professional to come out and fix it.

7. Pictures But no Sound

This issue is a lot simpler than a black screen, but you still hear sound. Make sure your volume is up. Check all of your remotes. You know you’ve got more than one. Also, check to make sure you haven’t muted it by accident.

Also, if you’re currently using a Blu-ray player or gaming console, double-check the connections. Those can come loose over time and affect both video and audio. If you’re using a USB, be aware that the USB may not be coded in a way that your Hisense TV can access, so there will be no sound.

Then make sure your TV isn’t hooked up to wireless headphones. Next, check and see if your TV is connected to a wireless sound system by going under Settings to Sound. If they are, then switch back to internal speakers.

If that doesn’t work, then do a power cycle reset to fix the problem.

  • Use the power button on your TV to turn it off
  • Unplug it for at least 30 seconds
  • Plug it back in
  • Turn it on

If that doesn’t help, then it’s time to make a call as there’s an issue with your TV, even if it’s just a connection issue with your internal speakers.

8. Hisense Smart TV Turning Off Right After it Turns On

If your TV is turning off right after you turn it on, there may be a couple of different problems. Here’s how to fix it:

  • Make sure you don’t have a faulty remote by removing the batteries and then manually turning the TV on to see if that fixed the problem.
  • Double-check the power cord and outlet for damage.
  • Try a different outlet and see if that helps.
  • Reset your TV by unplugging it for at least 15 minutes.

A note for those that live in apartments, if your TV randomly turns off by itself, make sure your neighbor doesn’t have a universal remote. If they do, they could be turning your TV off when they turn theirs on.

If none of that helps, then it’s time to call in a professional to take a look at the problem.

9. Not Connecting to Wi-Fi

When it comes to hooking up to the internet, there are always problems whether you’re hardwiring or connecting wirelessly.

Unfortunately, Hisense Smart TVs are not immune to this. However, there are a couple of ways to fix this issue.

  • Make sure another device can connect to your Wi-Fi.
  • If that’s okay, then disconnect other devices to see if it’s congestion causing an issue.
  • If you have different Wi-Fi networks for different bandwidths, move your TV to the other bandwidth to see if that solves the problem.
  • Clear your Hisense TV’s Cache under the Network setting.

This Hisense TV troubleshooting should take care of all the issues, and you should be able to connect to your Wi-Fi after that. If not, call your internet provider and make sure they aren’t having trouble on their end.
