What to do if your Samsung TV turns on and turns off immediately

No equipment is immune from premature failure. Therefore, even if you buy expensive equipment, still keep in mind that there is a possibility of the device breaking down. Of course, TV equipment from Samsung is no exception to this rule.

There are many different symptoms that indicate that the equipment is not working properly. The most common sign of device failure is that the Samsung TV turns off and turns on itself.

What to do in such cases? Of course, first of all you need to find out the reason for the incorrect operation of the equipment. Once you determine what caused the problem with your Samsung TV, you can quickly fix the problem. You can do this either independently or by contacting a service center.

External reasons

After carrying out basic diagnostics, the user will determine why the Samsung TV turns off on its own or, on the contrary, starts up randomly. As a rule, eliminating minor failures does not require special skills, so you can handle it yourself without contacting a service center.

Now we will analyze the most obvious reasons for the incorrect operation of external equipment, and also analyze the optimal ways to solve the problems that have arisen.

It’s clear that you absolutely shouldn’t disassemble the TV right away; first you need to check it for external faults:

• breakdown of the remote control;
• damage to the power cable;
• sleep timer;
• failure of the antenna or module for wireless Internet connection.

Now we will consider in as much detail as possible all the reasons listed above due to which TVs turn on automatically.

Troubleshooting

Causes and solutions to problems with rebooting the device:

1. When setting a sleep timer, you need to go to settings and disable it by finding the corresponding item. You need to look for sections with timers directly in the menu or on the remote control.
2. If the malfunction occurs due to a breakdown of the control panel, in particular, a malfunction of the buttons occurs, then the remote control must be replaced with a new one. If you don’t want to purchase a new controller, you can download a special program to your phone and control the TV device from your smartphone.
3. If the problem is due to the TV software, then you need to download the latest update and check if the problem goes away. It is this action that in most cases guarantees the operation of the TV. To download, you must carry out the operation from the TV menu or download the software from a flash drive, having first downloaded the desired program from the official website of the developer. Applying the settings helps solve the problem.
4. If dust gets on the batteries, you need to treat them with a vacuum cleaner. This simple action helps to cope with the constant reboot of the TV. When there is a large amount of dust generated, static electricity occurs, which damages the equipment. A short circuit occurs and the TV modes fail.
5. If the problem occurs due to moisture ingress, you must immediately open the back panel of the device and carefully remove the water and thoroughly dry each part.

If your Samsung Smart TV keeps rebooting, you should inspect it and find out the reason using the list of problems provided. Difficulties with repair arise only when the unit fails. All other defects can be corrected at home with your own hands. Problems may also arise on other brands - it is possible to reboot Philip and Sony on your own. The defect that has arisen will have to be eliminated according to the same scheme.

Broken remote control

If the TV turns on and immediately turns off, but does not respond to the remote control, then you need to check its functionality. Inspect the device for mechanical damage, check if the buttons are stuck, change the batteries.

Using your smartphone camera, you can check whether the remote control is firing from the infrared sensor. Point the camera at the sensor so that you can see it on the smartphone screen. Then press several different buttons, if there is no light, then the remote control is broken. The reason is that the battery life has expired or there is mechanical damage.

Causes

If the TV starts rebooting on its own all day at different or specific times (it is important to notice the time period to find out the reason), then you need to find out exactly what’s wrong. There are several main reasons why a TV may reboot on its own. Sometimes the problem arises due to trivial situations that can be easily resolved at home without the involvement of a specialist. In other situations, the intervention of a repairman is required, who must carry out diagnostics and competent repairs.

Sleep Timer

An unpleasant situation can arise for a trivial reason - the user set the sleep timer a long time ago and then forgot to deactivate the function. In this case, at a certain time, the TV will automatically reboot at the same time.

Some TVs also have a feature that turns off the equipment after a specific period of inactivity. This means that if the user does not perform any operations with the remote control for, for example, 1 hour, the TV automatically turns off.

This feature is useful if a person falls asleep in the evening while watching and does not want to waste electricity. But do not forget to deactivate the program if it is not needed, otherwise the device will constantly reboot at the same time.

Malfunction of remote control buttons

If your Samsung TV starts to reboot automatically and does not respond to the remote control signal, then you need to check the functionality of the remote control. First you need to check the batteries and pay special attention to the buttons. To test the device, you will need to turn on your mobile phone camera and point it so that the remote control is displayed on the screen with the infrared sensor facing forward. After this, you need to press any buttons. If there is no light on the camera, then the keys are faulty.

A reboot situation is also possible when a foreign object gets on the power button, and therefore it constantly activates it. In this case, the TV will turn on and off (the screen is completely deactivated) when the remote control is pointed directly at the TV unit. In this version, the TV sometimes reboots 3 times a day or more.

TV software

One of the main reasons for hardware failure is outdated software. To keep the equipment in working condition, you need to periodically go into the settings and update the software. The main symptom: it turns off for a couple of seconds, and then the TV starts working again for a while without failures.

Ingress of moisture or dust

When moisture gets inside the TV, corrosion occurs on the contacts. In such a situation, the performance of the internal parts may be unstable and this is the cause of the malfunction - the TV will reboot. Also, a similar difficulty is caused by excessive dust accumulation on the remote control or inside the TV itself.

Problem with the power supply

If a reboot occurs due to a failure of the power supply, then it will be difficult to cope with this task on your own without damaging the equipment. It is not recommended to repair the unit if you have not previously had experience with such repair work. The user can only cope with a complete replacement of the unit, but it is better to entrust the repair of individual parts to a specialist. To understand which unit is damaged, you first need to inspect the capacitor, and only then the other elements.

What to pay attention to if the TV starts to reboot:

1. Reliable fixation of all elements.
2. The appearance of swelling on the equipment.
3. The appearance of foreign formations.
4. Blackening of parts.

If at least one of the listed defects appears on the power supply, then the failed element must be urgently replaced or the module itself must be completely replaced.

Problem with the socket

If the TV stops working on its own, be sure to inspect the cable, power adapter, and outlet the device is plugged into. Lack of power supply during non-contact causes malfunctions, as a result the TV will turn off, thus going into protection mode.

Proceed as follows:

1. Check connectors and plugs for mechanical damage.
2. Are there any fractures or kinks in the power cable?
3. Look to see if dark spots or charring have appeared on the fork.
4. Securely secure the socket.

If possible, connect the TV to a different outlet.

Wi-Fi disappears

Problems with a wireless Internet connection can arise not only due to a broken Wi-Fi adapter, but also due to software glitches or incorrectly configured settings. It cannot be ruled out that the router was causing the problem. Try connecting to your home network using other devices, such as a smartphone. If everything works, then the Smart TV LCD TV requires replacing the Wi-Fi module; to do this, contact a service center.

Problems with TV

Troubleshooting television equipment should begin with a complete reboot; perform a complete reset of user settings. Disconnect the device from the mains to briefly relieve the capacitors; they should cool down a little. Wait literally 1-2 minutes, and then turn on the TV again.

The main thing is not to confuse a hardware failure with a software failure. Operational-type problems are resolved by installing the latest service pack. With hardware it is a little more difficult, because you have to disassemble the TV.

If you have updated the operating system, but Smart TV still lives its own life, then you need to dismantle the back panel and look for the cause of the problem with the hardware component of the device. If you do not have the skills to disassemble TVs, then it is better to contact a service center.

What should you consider when disassembling television equipment? First, to remove the back panel, you need to unscrew the screws, for this you will need a screwdriver of the appropriate size. When unscrewing fasteners, remember their location, otherwise you will encounter serious problems during the assembly process.

Secondly, if you replaced a faulty hardware module and now want to check if the TV is working, you should replace the back cover and tighten all the bolts. All this is done for safety reasons.

How to Force a Factory Reset Using TV Buttons

ATTENTION . A hard reset will erase all of your TV's custom settings, including installed apps, system data, channel sorting, and wireless network settings. Demo content for playback at retail locations on ZH8 models will also be removed from internal memory. If you have access to the TV's menu, it is recommended that you perform a factory reset instead of a force reset.

Before starting a forced factory reset

• This procedure may require two people.
• The location of the buttons depends on the TV model.
• After performing a hard reset, you may be able to recover some app data that was synced with your Google™ account. The procedure for syncing apps varies depending on your TV menu options: HOME → Settings → Device settings or Accounts & sign-in → Google → Select synced apps → select the items you want to sync with your account → Sync .
• HOME → Settings → Google → Select synced apps in the Sync → select the items you want to sync with your account → Sync .
• HOME → Settings → Personal settings → Google → Select synchronized applications in the Synchronization → select the item you want to synchronize with your account → Synchronize .

How to force reset

First of all, determine the number of buttons on the TV. To see where the buttons are located on your TV model, follow this link.

1. Only one button on the TV:
   the (
   Power
   ) button is located at the bottom center or left side of the TV when viewed from the front.
2. Three buttons on the TV:
   The buttons are located on the right or left side of the TV or on the back panel, depending on the model.

If you cannot find the buttons on your TV, refer to your TV's instruction manual. Instructions and manuals are posted on the support site page for your model.

Follow the instructions according to the number of buttons on your TV.

Type A:

There is only one button on the TV

1. Unplug the TV's power cord from the electrical outlet.
2. Press and hold the ( Power
   ) button on the TV (not the remote control), then while holding down the Power button, plug the power cord back into the outlet. Continue holding the Power button until the white LED turns on. The indicator will turn white for 10 to 30 seconds.
3. When the indicator turns white, release the button. If the indicator does not turn white within 30 seconds, start the procedure again from step 1.
4. Wait a few minutes for the force reset process to complete. The TV will reboot (turn on and off) twice. If the TV does not turn on automatically, press the ( Power
   ) button.
5. When the initial setup screen
   , configure the settings.
   If the initial setup screen
   does not appear, unplug the power cord and then plug it back in.

If a hard reset does not resolve the issue, perform the procedure again from step 1.

Type B:

There are three buttons on the TV

1. Unplug the TV's power cord from the electrical outlet.
2. Simultaneously press and hold the buttons (Nutrition
   ) And
   decrease volume
   on the TV (not the remote control), then while holding down the buttons, plug the power cord back into the outlet. Continue holding the buttons until the green LED lights up.
   NOTE. The indicator will turn green for 10 to 30 seconds.
   POWER button
3. Volume down (-) button
4. TV back panel

• If the TV does not turn on automatically, press the Power
  .

1. When the initial setup screen
   , configure the settings.

• If the initial setup screen
  does not appear, unplug the power cord and then plug it back in.

If a hard reset does not resolve the issue, perform the procedure again from step 1.

Dust or moisture has gotten inside

If dust has accumulated in the hardware component, it must be removed using a vacuum cleaner. Mostly, this simple action allows you to solve the problem with periodic spontaneous turning on of the TV device. The thing is that dust conducts electric current, in addition, even a small clot will be enough for static electricity. As a result, a short circuit occurs. The TV switches to protection mode.

Moisture causes corrosion to form on the contacts, causing the signal to be transmitted unevenly. Therefore, if moisture gets inside, you should clean it immediately.

Reverse malware

• Contents of the issue
• Subscription to "Hacker"

Well-known hacker Luigi Auriemma discovered an interesting bug in Samsung TVs and Blu-Ray players with WiFi support. All of them have the function of remote control from a mobile device via TCP port 55000. For example, here are the corresponding programs for iOS and Android:

https://itunes.apple.com/us/app/samsung-remote/id359580639 https://play.google.com/store/apps/details?id=com.samsung.remoteTV

Each TV has more than 40 TCP ports constantly open, including port 55000, which is responsible for remote control.

When a new packet is received on port 55000, the TV displays a message stating that a new remote control device has been found, and the user is given a choice whether to allow or deny working with it. The message contains lines indicating the name and MAC address specified in the packet. The bug is that if a line in the package is formatted incorrectly (for example, contains inappropriate characters), then after selecting any menu item the TV begins to behave strangely: for five seconds it works as usual, then it stops responding to control buttons, even to hardware buttons on the TV itself, then starts to slow down and eventually stops working completely. After another five seconds, the TV reboots automatically - and the cycle repeats again.

During this cycle of endless reboots, it is impossible to even activate a reset because it requires holding the EXIT button for 15 seconds, which does not work in this situation. It is also impossible to perform other actions that would not violate the terms of the warranty.

This situation can be avoided if you press the EXIT button after the above message appears, that is, immediately after receiving the packet from the new device.

The researcher suggests that in light of this vulnerability, a way can be found to cause a buffer overflow and disable the TV. Luigi Auriemma decided not to experiment on his TV, so he did not give an exact answer to this question.

Interestingly, Luigi never found an address on the Samsung website where to send bug reports.

The vulnerability was tested on the Samsung D6000, but should be present in other models, including these and subsequent series: LCD 650, LED 6500 and PDP 6500 (with the [ email protected] ), LCD 550, LED 5500 and PDP 5500 (with the [email protected] function AllShare), BD-Player D5300, BD-HTS D5000, BD-AVR D7000, BD-HDD Combo D6900/8200/8500/8900, etc. (with Smart Hub function).

Problems in electrical circuits

If you still have doubts, you can diagnose this type of breakdown yourself:

1. Turn off the TV and then remove the back panel.
2. Inspect the condition of the board yourself; for this you will need a magnifying glass or magnifying glass.
3. If a part is cracked, it needs to be replaced; spare parts can be purchased at the appropriate stores.

Restoring electrical circuits is an extremely serious problem, so it is best to entrust its repair to a specialist.
