Why Does my Sharp TV keep Shutting OFF by itself?


My sharp TV keeps on shutting off- Why?

Your Sharp TV may keep shutting off on its own because of a faulty power supply or a loose and damaged HDMI cable. Keeping your TV in a cool environment can prevent the TV from overheating and turning off.

 

Causes

  • Power issue
  • Cable issue
  • Overheating

 

Power issue

Your TV needs a stable supply of power to function properly. So, if it receives an unstable or insufficient supply of power, it will begin to malfunction. 

Usually, the most common reasons behind your TV facing issues with the power supply are an issue with your electricity supplier, a loosely connected power plug, or a faulty power plug. 

The bottom line is that no matter what causes your TV to receive insufficient or unstable power, if the issue gets to a certain point, your TV is going to turn off automatically.

 

Cable issue

Cables are the bridges that delegate information from external, peripheral devices to your Sharp TV. If these delegating channels get damaged or are loosely connected to your TV, they will start sending mixed and interrupted information to your device. 

This can cause your TV to glitch up in many different ways. Particularly, when the issue gets intense, your device will turn off automatically to protect itself.

 

Overheating

While your TV is designed to withstand a certain amount of heat for long periods, its internals will get severely damaged if things get out of hand. 

Overheating occurs when you put your TV through long hours without breaks – especially when the usage is intense. This issue can amplify even further if you haven’t kept your TV in a cool space (where preferably there’s a lot of air circulation).

 

How to prevent my sharp TV from shutting down repeatedly?

To prevent your Sharp TV from shutting down repeatedly, either conduct a cable reset, a power/ soft reset, or give it sufficient cooldown breaks between long usage.

Power reset

  1. Press the red remote’s power button to switch off the TV and unplug its power cord from the wall socket.
  2. Now, move over to the screen and find the TV’s main power button below it. Press it downfor about half a minute, and then release it
  3. Let your TV remain unplugged for about 10 minutes or so
  4. Plug your TV into the wall.
  5. Start it up using the remote.

 

Cable reset

  1. Press the power button on your Sharp TV’s remote to turn it off.
  2. Now, unplug it from the socket.
  3. Pull out each cable that your device is connected to.
  4. Now, clean the ends of the cables as well as your TV’s ports
  5. Check your TV’s ports for signs of damage.
  6. Check your cables for signs of damage.
  7. Replace damaged cables
  8. Call an expert or Sharp’s customer support to have your TV’s damaged ports replaced. Do not try to install new ports on your own- it risks damaging your TV.
  9. Securely place the cables into their slots.
  10. Turn your TV on.

 

Cooldown breaks

Overheating occurs when you watch TV for multiple hours on end or when you put it to do a lot of heavy tasks. This is fine when it is at normal levels, but it can start adding up and get to a point where it might damage your TV’s internal hardware. 

Giving your TV ample time to cool off between long usage is the best way to ensure that it remains safe from any overheating problems.

 

Sharp TV is turning off by itself

 

Why is my Sharp TV shutting down by itself?

Your Sharp TV keeps shutting by itself either because its backlight has deteriorated, its software isn’t updated, or because of a random glitch. 

 

Causes

  • Damaged backlight
  • Glitch
  • Outdated software

 

Damaged backlight

A damaged backlight will not function properly. Time and again, it might cause result in the screen adjusting and going black- giving you the impression that your TV has shut down. 

Your backlight can get damaged due to excessive force, wear, and tear or overheating.

 

Glitch

Sometimes, there’s nothing more to your TV shutting down randomly than a simple glitch. Restart your TV to resolve the problem.

 

Outdated software

Software updates come with improvements and bug fixes on older versions. If you’re using an older version of your TV’s software, the bugs and faults of the older versions will still remain- sometimes translating into your TV shutting down for no reason.

 

How do I stop my Sharp TV’s auto-shut-down problem?

To prevent your Sharp TV from shutting down without cause, either update its software, restart it, or get support for repairs/ replacements. 

 

Update software

  1. Tap the menu option on your remote.
  2. Go to settings
  3. Go to support
  4. Find the check software updates option
  5. Click install now if an update is available

 

Restart your device

This is as simple as switching your TV off using the remote, pulling out the power plug, waiting for a minute or so, and then re-plugging your TV to the main power.

 

Call support

Calling customer support should be your first instinct as soon as you realize the issue is related to your screen’s backlight. This way, you can get your TV repaired without risking your warranty claim. 

Of course, if you don’t have a warranty, you could call an expert for the job. But try to prioritize official customer support. In any case, do not attempt the repairs by yourself- it risks damaging your TV permanently.

 

 

Why does my Sharp TV’s backlight go dark?

Your Sharp TVs probably go dark because the ambient lighting detection feature is glitching. 

Auto-brightness is a really helpful feature that helps you save energy and reduce the strain on your eyes due to really bright screens. The feature adjusts the TV’s screen to match the surrounding light levels to ensure that the image is not too bright but visible at the same time. 

If your TV detects lower ambient lighting than is actually present, your screen will go dim- appearing as though the backlight has dimmed down.

 

How to turn on my Sharp TV’s backlight?

You can switch your Sharp TV’s backlight back by deactivating auto-brightness via the settings and manually increasing the brightness. 

Below is the method you need to follow to deactivate auto-brightness on your sharp TV:

  1. Click the remote’s menu option.
  2. Go to settings
  3. Go to “picture” in settings
  4. Find advanced settings
  5. Switch off auto-brightness
  6. Exit the menu
  7. Use the remote to manually adjust your screen’s brightness.

 

Why does my Sharp TV blink every time I turn it off?

The most common reason why your TV might blink each time you switch it off is that it is facing HDMI or other cable connectivity issues.

Most people connect at least one peripheral device to their TVs. These connections are facilitated through cables that carry information from one device to the other. 

Since cables bridge the flow of information between two or more devices, they need to be firmly and securely connected to the ports of each device. 

If they’re loosely plugged in, or if the cables are faulty, the information won’t properly flow between devices- causing glitches and other problems. 

One common symptom of this is that the screen will flash or blink each time you switch it off.

This can leave you pretty confused, and you might think there is some issue with your TV backlight. However, in most cases, cable issues are to blame for this, and this problem will go away with a simple cable reset.

 

Here’s how to do it:

  1. Press the power button on your remote to turn it off.
  2. Now, unplug it from its socket.
  3. Pull out each cable that your device is connected to.
  4. Now, clean the ends of the cables as well as your TV ports
  5. Check your TV ports for signs of damage.
  6. Check your cables for signs of damage.
  7. Replace damaged cables
  8. Call an expert or Sharp’s customer support to have your damaged ports replaced. Do not try to install new ports on your own- it risks damaging your TV.
  9. Securely place the cables into their slots.
  10. Turn your TV on.
