Why Does My Sharp TV Keep Turning Off

1. Bug or Software Malfunction

A bug or software malfunction is a typical issue when purchasing a smart LED tv. Although a bug or a software malfunction is common, there are quick ways for you to resolve the issue right away. So, before you go into a frenzy, let’s take a look at some of these quick fixes, shall we?

Fix – Unplug the TV and hold Power Button for 30 Seconds

Some people wouldn’t consider unplugging your television and plugging it back in as a way to resolve an issue since many people fear the problem would persist.

However, this troubleshooting method is worth a shot if you’re looking to resolve the issue immediately and if you are fixing the issue on your own. This method of choice is considered a manual reset without factory resetting the TV. So this alternative is beneficial.

To get started with this process, first, you must:

1. Go ahead and unplug the TV from the outlet.

2. After the television is unplugged, hold down the power button on the TV for 30 seconds.

3. Doing this will give the TV a “jump”. The only difference is you are not using an alternate device to provide the television with a jump start like how a vehicle with a dead battery needs another vehicle for a successful jump start.

4. After 30 seconds, go ahead and plug the TV cord back into the outlet and turn the television back on.

5. After turning the TV back on, resume watching your previous program. If the television does not turn off instantly after a short time, you have resolved the issue.

After performing this troubleshooting method and the issue continues, proceed to the next alternative.

Fix 2 – Unplug and Plug TV In After 60 Seconds

For this step, instead of waiting 30 seconds after unplugging the television, you will wait 60 seconds instead. But, the power button does not need to be utilized for this method.

After unplugging the TV immediately, wait 60 seconds before plugging the television back into the outlet.

After waiting for 60 seconds, plug the TV cord back into the outlet and power the television back on. This quick reset should allow the TV to Now function properly. If this does not work, attempt to restart the TV using your remote.

Fix 3 – Restart TV with Remote

Restarting your TV with your remote is a straightforward process. If you have turned your television back on after it has turned off automatically, you can do this by simply turning your TV back off using the power button on your remote. After leaving your TV off for approximately 2 to 3 minutes, use your remote control to turn your television back on.

Keeping the television off for a couple of minutes will give the electrical current in the television a break. This may be a great option if your TV has been running consistently.

Fix 4 – Wait For Problem to Go Away

No one ever likes to wait for an issue to resolve on its own. Although waiting is an option, there are other steps to take while you wait for the issue to resolve on its own.

While you’re waiting for the issue to go away, take a moment to observe all of the inputs and outputs of your television to ensure none of the technical inputs or outputs are causing the issue.

Play around with the TV’s functionalities and buttons to see if the issue occurs when you press a particular button or make a specific selection. And while you’re waiting for the issue to fix itself, try checking out some troubleshooting methods online to pass the time, just like how you’re checking out this article as we speak.

So, although waiting can be a pain, there are still ways for you to utilize your time and space while the issue is internally resolving itself.

If you’ve waited long enough, you may want to check out the next alternative.

Fix 5 – Plug TV Into A Different Outlet

Consumers fail to realize that it is essential that your device is FIRMLY and safely plugged into an outlet. If your Sharp TV is turning off by itself, even if your TV is firmly plugged in, you may want to try using a different outlet.

When transitioning your TV to a different outlet, it is crucial to consider to safely and carefully switch the television from one location to another in your vicinity. Be sure when switching the television to pick up the TV cord as you are traveling from one location in your home to the other.

Also, ensure all external wires are disconnected from the TV before transitioning. This is essential for consumers who have their TV plugged into an outlet that does not have an alternate outlet next to the outlet they are switching from.

If the outlet you are switching from already has a second outlet next to it, go ahead and unplug the TV and plug it into the alternate outlet.

Switching outlets allows you to isolate the issue because your current outlet is not strong enough to hold the TV cord in place. This issue can be very hazardous.

If your TV is plugged into a loosely tightened outlet, it will not only continue to turn off on its own, but this may also spark a fire. So, consider this information to avoid a nightmare such as a house fire.

Suppose you are using an external outlet (or drop cord), and the external outlet is plugged into the wall. In that case, if there is an additional wall outlet nearby, you can try switching the external outlet cord into a different wall outlet to see if this will isolate the issue.

After you have switched outlets, try turning your television back on and resume watching your scheduled program. If the TV remains on for a more extended period of time, you have resolved the issue. However, if the issue continues, you may have to use a different resolution method.

Fix 6 – Reset TV to Factory Default

Factory resetting your TV will give your television a fresh start. However, it is vital to consider any data or information that may be lost after the initial setup.

If you have a Sharp Smart TV with applications downloaded, after the factory reset, you may have to reinstall those applications again. Here are a couple of ways to reset your Sharp TV to factory settings.

To factory reset your Sharp TV, you must:

1. If your TV is already turned off, turn the TV back on.

2. Navigate to the menu. You can do this by using the toggles on your TV or using your remote.

3. Go to set up.

4. Find and select the Reset option.

5. When selecting the reset option, the system may ask for a pin code or parental control password if any was used prior.

6. After entering in the code (if applicable), the system will automatically reset and restart.

After the system has reset, try to resume or turn to a station on your TV and pay close attention to see if the TV will remain on.

To factory reset your Sharp TV, you can also do the following:

1. Go to your TV settings.

2. Find and select System

3. Locate the Factory Reset option.

4. And press the Play or OK button on your remote three times to automatically start the reset process.

To reset your Sharp TV without a remote to factory settings, you must:

1. Unplug the television from the outlet.

2. Press and hold together the channel down and input buttons on the panel.

3. Plug the TV in and continue to hold down buttons. You may need a little assistance from another person to accomplish this step.

4. Continue holding the buttons down until the television powers back on. If it doesn’t work, unplug the television and try again. Keep in mind that sometimes this process doesn’t work the first time around.

5. Find the Service Mode menu and select Factory Reset from the menu.

6. Use the channel up and down (Ch+/-) buttons to select an input to confirm.

After using one of the methods to reset your TV to factory reset settings, this may resolve the issue immediately.

2. A Faulty App is Causing It

When you first purchase a Sharp TV, the first thing consumers want to do is download fun applications on their TV. But when apps are running for a consistent time frame, running apps can cause an internal issue with the functionality of your TV.

Fix – Close the App

To close your apps on your TV, you must:

On your remote control, press the home button. At the home screen, select the apps icon or press and hold the home button to open the list of installed apps.

Press the left, right, up, or down arrows to highlight the apps you want to choose. Press and hold the Enter button on the selected application. When the option to Force Close appears, select Force Close.

If multiple apps are running simultaneously, force close all running apps.

Fix 2 – Clear Apps Cache

Your cache backup may also be an issue for why your TV is turning off automatically. A cache is where the device stores files from the apps you have open on your smart TV. These files or any other data are kept temporarily in your cache memory.

The cache will use the data to help the app perform more efficiently. However, many files are stored in your cache memory and can also take up space on your Sharp TV. So clearing the cache would be essential for your TV to function correctly.

To clear your cache on your Sharp TV, you must:

1. First, go to the home screen of your Sharp smart TV.

2. Select all apps

3. Look for the settings and tap to open.

4. Now, select apps.

5. Choose the All tab to see all of your apps.

6. Click on the app that you want to clear the cache

7. Next, select the clear cache option.

8. Repeat this process for all of the other running applications.

Once you clear your cache on your Sharp TV, turn the TV off and back on. Once the TV is back on, attempt to watch a program on the TV to ensure the TV will remain on.

Fix 3 – Delete the App, Reboot, Reinstall

If the previous alternative did not work, the following method might be time-consuming. Although this method may take some time, it may get your Sharp TV back to its 100% potential.

First, you will have to delete the apps from your Sharp TV. On your TV home screen, scroll to Settings; under “Device”, select Apps. Under Downloaded Apps, choose the app you want to delete. Finally, select Uninstall and then click OK. Repeat this for all apps on your TV.

After successfully uninstalling all apps from your TV, reboot the TV. To reboot, you can turn the TV off using your remote, use the power button on the TV, or unplug the TV from the wall outlet. Leave the television off for approximately 2 minutes.

After 2 minutes have passed, turn the TV back on. If the TV is unplugged from the wall outlet, plug the TV cord back into the outlet and switch the television back on.

After the television is back on, reinstall all of your applications again. After all of the apps are reinstalled, attempt to watch a program on the TV to see if the system will remain on for the entire duration.

3. TV Overheating

As the most likely issue is that the television is overheating, you should check the air vents behind your Sharp TV to ensure they are not blocked or full of dust hence why it is essential to perform a periodic check on your ventilation.

Fix – Wait For TV to Cool Down

If your Sharp TV is turning off automatically due to your system overheating, the best thing to do in this scenario is to wait for your TV to cool down.

While it may be complicated to decipher whether or not this may be the issue, you can usually tell by looking at the air vents on the back of the television. If the vents seem too hot to touch, don’t have enough wiggle room, or are filled with dust or debris, your Sharp TV is most likely overheating. So your best option is to turn your television off for a while for the system to cool down.

4. Loose Or Weak Cable Connections

It is essential for your safety as well as for the functionality of the TV to check for loose or weak cable connections. If your Sharp TV is turning off by itself, there may be a shortage and one of your connections as well as cables that may be loose or not firmly connected.

Fix – Plug In Power Supply Firmly

If the cables are loose, unplug the cables and reinsert them firmly. Be sure to check the wall connection as well as the cables connected to the TV.

Once you reinsert the cables back into the TV as well as the wall connection (if applicable), if your TV is already off, turn the TV back on and attempt to watch something.

The issue is resolved if the TV remains on for the entire duration after all cables and wires are firmly connected. However, if the problem continues, you may want to try checking your HDMI cable. Let’s check out that alternative for reinstalling your HDMI connection.

Fix – Reinstall HDMI

On your Sharp TV, your HDMI connections are located either on the back panel or, for some models, located on the rear side panel.

Sometimes, your HDMI cables or connection may cause a short circuit if not taken care of right away. This can prohibit your display from working properly and cause your TV to turn off by itself.

If your Sharp TV is turning off automatically, if you have HDMI cables attached to the HDMI ports, remove them and then reinstall them.

When removing the HDMI cables, it is essential to remember to slowly wiggle the cables from the ports rather than quickly snatching them out. This will cause more harm than a solution.

After you have reinstalled the HDMI cables, try to resume watching your TV to ensure it does not turn off again.

Fix – Replace HDMI

After removing the HDMI cables and reinstalling them, and there is still no progress, check the cables for damages.

Having a damaged HDMI cable is terrible news. Not only will the cable continue to cause issues for your television, but this is a hazardous situation.

If you notice the issue is your HDMI cable, the best option is to replace the HDMI Cable (view on Amazon).
