12 Fixes for Insignia TV Black Screen
1. Test the HDMI Cable Connection
This test and fix is also valid for other types of cables and not only HDMI cables.
The first thing that you should do if you have a problem with your Insignia TV having a black screen is to test the HDMI cable connection to your streaming device or other external device, like a smart hub or DVD player.
The cable might be loose from either end or there could be something wrong with the cable. To check if it’s a problem with the cable, follow these steps first:
- Look for and check the HDMI cable on the back of your TV.
- Unplug the HDMI cable on the TV and plug it back in.
- Unplug the cable on the external device.
- Check the TV for an image.
If there’s still no image and it’s a black screen on the Insignia TV, you can perform a signal test to see if it’s a problem with the HDMI cable. Follow these steps to perform the HDMI cable test:
- Navigate to Settings
- Select Support
- Select Device Care
- Select Self Diagnosis
- Select Signal Information
- Select HDMI Cable Test
- Select Start Test.
The cable test will let you know if the HDMI cable is “Good” or “Bad.” If the test says that the HDMI cable is bad, use a different cable to see if that works.
If the test says good, let’s move on to the next solution to try.
2. Check the Input Source of the Insignia TV
Sometimes when you turn on the Insignia TV, it’s on a different input source than you are expecting. Maybe someone else was using the TV before you and switched the input source.
There are a few different things to try here with the input source:
First thing to do, double-check that you are using the HDMI 1 TV source if that’s where your streaming, cable, or other device is connected. Make sure your external device is turned on as well.
Second thing to try, if there’s no picture in HDMI 1, try checking HDMI 2 and the other input sources to see if they will give you a picture on the TV screen or if it’s still a black screen.
If you see images on the other input sources, then there could be an issue with the HDMI 1 port or the external device.
Third thing to try is to remove all the other HDMI cables in the other sources on your TV. One of them could be affecting the HDMI 1 from functioning correctly.
3. Try Different External and Streaming Devices
Another possible cause of a black screen on a Insignia TV is a problem with your streaming device, like the Roku or Apple TV, cable box, or even gaming console.
If there is a black screen on the Insignia TV, but you still hear sounds coming out, then you know that the TV is turned on. The black screen could be caused by a video output issue with your external device, and not because of your TV.
Let’s try using other external devices in the HDMI port to test if it’s an issue with the external device or the HDMI port itself.
- Plug another external device into the same HDMI port.
- Confirm the Insignia TV input source is correct and see if you have an image.
- If you have an image and sound, then it’s an issue with the external device and its video output.
- If you still have a black screen with sound, then it’s an issue with the HDMI port or the TV itself.
4. Try a Soft Reset or Reboot of the Insignia TV
With Insignia smart TVs becoming more powerful and ability to run processes like a computer, a soft reset can help. It will clear any settings on the internal components of the Insignia TV, but not your personal settings.
A soft reset, also known as a power cycle, will also stop any background processes and apps that might’ve been causing black screen issues. Soft resets can also help with other issues like slow Wi-Fi speeds and Bluetooth connection problems.
To perform a soft reset on a Insignia TV, follow these steps:
- Unplug the TV’s power cable for at least 60 seconds.
- Plug the cord back into the power outlet.
That’s all there is to a soft reset.
Another thing to try is to reboot the Insignia TV, which can also help with various issues.
- Unplug the TV.
- On the Remote, Press and Hold the Power button for 30 seconds.
- Plug the TV back into the power outlet.
5. Configure the Insignia TV Input Settings
Black screens on the Insignia TV can occur with bad input settings for the input source. To check this, first make sure that the TV is powered on.

- On the remote control, Press the External Power Source button.
- Select Input Settings.
- Go over the TV Inputs and make sure they’re all Enabled.
- Go back to Input Settings.
- Make sure the other Input Source Settings have no issues.
- Save the Settings.
- Try the TV again.
6. Turn Off Power Saver and Sleep Timer
Power saving and sleep timer are two features on some Insignia TVs that can cause black screens on the TV. These features are great for saving on your energy and electric bill, but they can potentially lead to black screens of death.

Firmware controls how the Insignia Smart TV works internally. It controls the menus, settings, how pictures are interpreted and shown on screen, and much more.

8. Protect the Insignia TV From Voltage Fluctuations
Voltage fluctuations in the home can sometimes cause black screens and frozen screens on the Insignia TV. This occurs because the voltage fluctuates too high or low, causing the TV to not function and display correctly.
If you experience black screens on your Insignia TV, using voltage management devices such as surge protectors or uninterruptible power supplies (UPS) can help prevent display issues.
These surge protectors will protect the devices connected to them from voltage fluctuations.
9. Factory Reset the Insignia TV
So you’ve tried all the other potential solutions above, but you’re still having black screen issues on the Insignia TV. Before opening up the Insignia TV, this is one last potential fix, a factory reset of the TV.
Factory resetting the Insignia TV to its original factory settings can solve many problems caused by software errors.This is one of the last non-hardware solutions to try because a factory reset removes any personal information stored on the TV, including saved passwords, usernames, and favorites.
Resetting the TV will all clear out all of its settings and data. If you’ve been experiencing problems with your TV, resetting it may resolve the issue.
Here is how to perform a factory reset on your Insignia TV with a black screen:

10. Check the Insignia TV T-CON Board
Now we get into potential Insignia TV hardware issues. The Insignia TV T-CON board is what creates the image on the TV screen. The T-CON board creates the horizontal and vertical lines that make up the picture, and it’s located below the main circuit board.
The T-CON board has an LCD driver chip that controls the backlight brightness. When the T-CON board malfunctions, the backlight becomes dimmer than normal. This causes the colors to become darker and less vibrant.
If the T-CON board is malfunctioning, you can buy a new T-CON board to replace the current one. These circuit boards are relatively inexpensive and under $100, even under $50 for the majority of Insignia TVs.
You can find T-CON boards on Amazon for your Insignia TV.
Here is a great video on how to replace the T-CON board on an Insignia TV.
11. Check the LED Backlight Strips in Insignia TV
LED backlights are used in Insignia TVs and most modern televisions. The LEDs emit light that’s converted into images displayed on the television screen. When an LED backlight fails, the image quality decreases, which causes the picture to appear dark and blurry.
To replace the LED backlight strips in the Insignia TV, you’ll need to disassemble the TV, which is not easy.
It is definitely best to get an Insignia service team member to repair the backlight strips or you may cause other issues.
Here’s a video of what it takes to replace the backlights on a Insignia TV:
12. Check for an Active Insignia TV Warranty
Most Insignia TVs come with a warranty for 1 year from the purchase date. If your Insignia TV is still under its warranty period, then you should contact Insignia Support directly about any problems you’re having. The warranty you have may cover replacements and/or repairing various parts of the TV.
If you bought the TV at a retail store, you might be able to buy an extended warranty for it. Retailers often offer warranty extensions on products they sell you to increase revenues.
Extended warranties are often better than manufacturer’s warranties. If you’re buying a big ticket item like a Insignia TV, the extended warranty may be worth considering.
