The black screen on your Insignia TV is a solid indication that something with the hardware or software on your television has gone wrong.

Let’s learn more about what’s causing the issue!

The black screen on an Insignia TV can be fixed by inspecting the power supply of the device and making sure all external devices are connected properly.

It’s also necessary to test the TV backlight and then reset the device’s software to eliminate potential faults.

Let’s proceed with unwrapping the suspects!

Reasons Why Insignia TV Won’t Show Picture?

1. Incorrectly selected television input source
2. A power issue with your Insignia television
3. A fault in the cable configuration of the TV
4. Improperly adjusted picture/video settings
5. A software fault with the firmware of your TV
6. Lowered or not-working backlight feature
7. Overheating of the TV due to continuous usage

Important!!!

In case any liquids went into the television or the issue appeared after a recent power outage, it’s likely that the hardware might be damaged.

In such cases, it’s best to check whether the device is receiving power by observing the front LED (power) indicator light.

How to Fix Insignia TV With No Picture But Has Sound?

Tip: Using the sound as an indication, check whether you can interact with the TV menus!

1. Check the Input Source

If an improperly-selected source is causing the black screen, the source menu of your TV should still be accessible.

For this purpose, you will need the Insignia remote and locate the “Source” button, which brings up the input menu.

• Point the remote towards the TV and press the “Source” button!

On the menu that should appear, deselect any input sources and press on “Watch TV”.

Your Insignia TV will revert back to the default-tuned OVA channels, that should be available.

2. Power Cycle the TV

The next step is to perform a power circulation in order to eliminate the fault with your Insignia television.

This is an advanced way to restart and refresh your Insignia TV and hopefully resolve any impermanent software-related blunders.

Here’s the easiest way to perform a power cycle on your Insignia TV:

1. Press the Power button on your Insignia remote.
2. Unplug the A/C cord of your Insignia TV on both sides.
3. Hold the “Power button” on your remote for 30 seconds.
4. Reconnect the power cable of the television to the power.

Note: It’s essential to ensure that the electrical outlet is functioning properly!

3. Examine the TV Wiring!

A fault in the cables can certainly lead to a black screen problem with the Insignia TV.

To verify that all cables are correct, you must perform a genuine checkup of the wirings in your setup!

Here are the important cables you should check:

• All HDMI cables – ensure that any external devices connected with HDMI are on
• The A/C adapter – verify that the power cable of the television is in good condition
• RCA cables – for any connected audio devices, check if their cables are secured
• Coaxial cable – for services delivered to your TV, the coax must be connected

The general issue you should be on the lookout for while inspecting is loose cable ends. Also, you should keep in mind that the cables in your setup shouldn’t be twisted or under pressure!  

Tip: Test the television screen with all external devices disconnected from the Insignia TV.

4. Test & Adjust Backlight

A low backlight setting might deceive users into thinking that something is wrong, because the TV’s screen is pitch black, while the sound remains audible.

This is why we strongly suggest inspecting and adjusting the Insignia TV backlight. 

• Inspecting the Backlight

Prepare your mobile smartphone by turning on the flashlight. Get close to the Insignia TV and point the flashlight toward the display from close proximity.

Try to spot any visuals on the TV screen and in case there aren’t, darken your room and look closer.

• Adjusting the Backlight Setting

If your TV did have an image when shined with a flashlight, it means that the backlight has been lowered.

Use the flashlight of your phone to shine on the TV screen and navigate to Settings > Display > Picture > Backlight > “90%”.

Note: Feel free to adjust the backlight setting to an eye-comfortable percentage!

5. Use a Different TV Input

If you’re only experiencing the Insignia black-screen problem on a certain input with more than one device, the TV port might be the culprit.

After a long time of usage, the most frequently used video input ports on our TV start to wear out so we definitely need to test with another one!

Here are the available input ports on Insignia TV:

• HDMI ports 1, 2, and SIDE
• Composite (AV) jack
• Digital optical audio
• Headphone’s jack (3.5mm)
• Coaxial input jack 
• USB port

Info: Based on your video input, test an alternative port or switch to another type of video transfer connection.

6. Reset the Insignia TV

Though most Insignia TVs do not have a physical reset button on the panel, there’s still a way to execute the factory reset.

For units that don’t have a reset button, the “power” button does the same function, as it can revert your TV to factory defaults.

• The factory reset will reinstall the operating system, deleting ALL files!

Here’s how to apply a factory reset on your Insignia TV:

1. Unplug the TV from the power outlet.
2. Press the power button for 15 seconds.
3. Release the button and plug in the TV’s cord.
4. Use the remote control to turn on the Insignia TV.

If the reset did take any effect, your television will be back at the initial setup screen, where you have to adjust the general settings.

Follow the on-screen prompts to complete your TV setup!

7. Correct Power Supply Problems

The next and one of the most important steps is to inspect the power supply of your Insignia TV.

When the power is fluctuating or not stable, your TV may start experiencing an onset of issues, including a random black screen at given times.

Fortunately, most Insignia TVs are equipped with universal power cords, meaning you could use any A/C adapter in your household that will match.

For example, you may use the power cable from your older TV to install it in the setup of your Insignia television and test it.

Tip: Also try to identify power-related issues by listening for a “buzzing” sound coming from the Insignia TV’s equipment.

8. Replace the HDMI Cable

If your Insignia TV’ screen is only going black when a particular external device is connected, the fault is probably due to the HDMI cable.

Since HDMI units transfer both audio and video when they go faulty your TV may start experiencing issues in all functionality factors.

• Use a different (functional) HDMI cable to connect the external device!

Though it’s recommended to use a brand-new HDMI cable with your TV, using old ones as long as they are functional is also accepted.

In case that’s the culprit in your setup, you can prevent future issues by purchasing the PowerBear 4K HDMI cable to include in your setup.

9. Warm Up Insignia TV (Hardware)

When you haven’t turned on your Insignia TV for months, the capacitor assembly could be discharged or even charge capacitance.

The normal solution would be to replace the entire board but we’ve got you covered in such a situation without spending a penny!

Warm up the hardware components of your Insignia TV using a hot air blower!

It’s simple, and you only need to point the blower firmly toward the vents of your Isnignia TV throughout the session.

Do not overheat the TV so keep the warming session short for about 30 to 40 seconds and when you’re ready restart the Insignia TV.
