(SOLVED) Why Insignia TV keeps Turning OFF by itself?


Why My Insignia TV is constantly turning off?

A Insignia TV can keep powering down if there is a loose cable, unstable power supply, or outdated software is installed on the TV.

 

Causes

  • Loose cable
  • Power supply problem
  • Outdated firmware

 

Loose Cable

Cables bridge the communication between your TV and the peripheral devices that are connected to it.

If your cable deteriorates over time, or if it is loosely connected to your TV’s cable port, it will send mixed and interrupted signals to your Insignia TV. This will confuse the mainboard as it won’t be able to detect whether a peripheral device is connected or not. When the signals get confusing enough, your TV will shut down to avoid further malfunction.

 

Power supply problem

If your TV gets insufficient or unstable electricity, it won’t be able to function properly. At first, it will start glitching up, but when the supply gets unstable enough, your TV will shut down.

Most commonly, power supply problems are rooted in issues with your main electricity supplier, a loosely attached power plug, or a defective power cord.

 

Outdated firmware

Software or firmware updates bring about numerous improvements to previous versions. So, if you stick to an older software/ firmware version of your TV, you are bound to face glitches like these.

 

How do I repair my Insignia TV that is constantly powering down?

To prevent your TV from constantly powering down, either reattach its cables, fix the power supply, or install the latest software version.

 

Fix the power supply

Fixing power supply issues is fairly simple; just follow this method:

  1. Switch off your TV and disconnect it from the main supply
  2. Press and hold down the power button below your TV’s screen for half a minute
  3. Release the button and let your unplugged Insignia TV rest for 10-20 minutes
  4. Come back, plug your TV back in and turn it on.
  5. Make sure you plug it firmly into the socket.

 

Cable reset

Here is the method:

  1. Pick up your remote and press the power button to turn your TV off.
  2. Switch off power from the wall socket.
  3. Detach all cables connected to your TV one by one.
  4. Clean the cable ports of your TV and check them for signs of damage
  5. Check the cables for signs of deterioration/ damage.
  6. Check the cable wires for cuts.
  7. If anything is damaged, get it repaired or replaced.
  8. Plug all cables into their respective ports one by one.
  9. Turn on your Insignia TV and turn it off to see whether the screen stops blinking.

 

Update firmware

Use these steps to update your TV’s firmware:

  1. Navigate to the main menu
  2. Click System Information
  3. View Information and find system updates
  4. See If there are any updates available
  5. If there is a new version available, connect to the Wi-fi and click install now

 

Insignia TV keeps turning off

 

Why Insignia TV’s backlight turns off automatically?

The backlights of Insignia TVs turn off automatically when the ambient light detection feature fails or when the sleep timer runs out.

 

Ambient light detection

Ambient light detection usually works fine and benefits you by saving the strain on your eyes. However, if the detection feature makes an error and detects lower- than- actual light in the surroundings, it can dim your TV’s backlight appearing as though it has gone dark.

 

Sleep timer

Sleep timers are helpful in letting you modulate your screen time. However, if you set them on by accident (or if someone else turns them on), it can cause you a lot of confusion. Your TV screen will go black all of a sudden, and you will be left confused.

 

 

How Can I prevent an Insignia TV’s backlight from turning off?

You can prevent your Insignia TV’s backlight from turning black either by turning off the ambient lighting detection feature or by turning off the sleep timer.

 

Turn off ambient lighting detection

Here is how you can turn off ambient lighting detection on your TV:

  1. Go to the main menu
  2. Find picture settings
  3. Scroll and find advanced picture settings
  4. Find the auto-brightness feature
  5. Use your remote to turn it off

 

 

Turn off the sleep timer

Follow this guide:

  1. Go to the main menu
  2. Go to settings
  3. Scroll down to the system
  4. Find the time option
  5. Scroll to find the screen timer option
  6. Turn it off

 

 

Why does my Insignia TV keep shutting down on its own?

Insignia TVs will keep shutting down if their backlight panel is damaged or if the TV is overheating.

Causes

  • Overheating
  • Faulty backlight panel

 

Overheating

TVs are built for long usage. So, for the most part, you don’t worry about overheating too much. However, if you keep your TV in a place with virtually no air ventilation, or if you use your TV for heavy-duty work for long hours (without cool-down breaks), it will begin overheating. When this continues for long enough, your TV’s internals will get damaged. And to prevent this from happening, your TV will shut down automatically.

 

Faulty backlight panel

Backlights produce the images and videos you see on your TV screen. They take direct instructions from your TV’s main board and light up your screen accordingly.

So, if these take damage somehow (usually because of overheating or excessive force), they will start malfunctioning. If the damage is severe enough, the screen will go black from time to time, appearing as though the TV has shut down.

 

How to stop an Insignia TV that shuts down by itself?

Stop your TV’s random shutdowns either by giving it ample cool-down breaks or by calling tech support and repairing/ replacing the backlight.

 

Give your TV breaks

Giving your TV breaks ample breaks to cool down between long-term use is the only sustainable way you can prevent it from heating.

To help with this, you can also keep it somewhere with air circulation, but even then, giving it breaks a must. This is especially true if you’re using your TV for heavy-duty work.

 

Call tech support

If your TV is shutting down because the backlight panel has deteriorated, then your best option is to call tech support and have it repaired/ replaced.

Don’t try to fix it yourself, though. If you do, you will risk damaging your TV permanently.

 

Why do Insignia TV screens blink when I power them off?

If an Insignia TV’s screen blinks before it is turned off, it is usually due to there being a cable connection problem.

 

An average user will have at least one or two peripheral devices connected to their TV. Most commonly, these are things like gaming consoles and speakers, but there are a lot more peripherals you can connect to your TV today. The only problem is that the more the number of peripherals you connect, the higher the chances of you facing a cable issue with your TV.

 

Cable issues refer to any problems with your TV that might result because of your cables. This includes things like loose cable connections, deteriorated cable ports on your TV, or faulty cables.

No matter what the root cause is, these things will send interrupted, unstable, and mixed signals to your TV- confusing its main board about whether or not another device is connected to the TV. This will result in a cascade of glitches for your TV- including a screen that blinks when the TV is shut down.

 

A simple cable reset can stop the issue:

  1. Pick up your remote and press the power button to turn your TV off.
  2. Switch off power from the wall socket.
  3. Detach all cables connected to your TV one by one.
  4. Clean the cable ports of your TV and check them for signs of damage
  5. Check the cables for signs of deterioration/ damage.
  6. Check the cable wires for cuts.
  7. If anything is damaged, get it repaired or replaced.
  8. Plug all cables into their respective ports one by one.
  9. Turn on your Insignia TV and turn it off to see whether the screen stops blinking.
