Samsung LCD TV The power switch is frequently restarted before turning on

What do you mean by frequent restart of the power switch - 1. Do you turn the power switch on and off many times, or press (or use the remote control) to standby and turn on the button after turning on the power switch? 2. Or turn on the power switch, and the TV will automatically restart many times frequently? After the TV is turned on normally, use the standby and on buttons (or use the remote control), 3. Can the TV be transferred to standby and on normally?

These are all important factors in analyzing failures. Could you please provide us with more information?

From the analysis of the phenomenon you described, it can be preliminarily judged: 1. The TV and the plug are in poor contact with the mains power socket; 2. Poor internal contact of the TV power switch; 3. The starting circuit of the TV switching power supply is faulty.

Others may require your supplements for further analysis.

My TV is also this problem, asked the after-sales service, door-to-door 30 yuan, maintenance fee, 320 pieces, and another cost, and what did you have to do to give people350

So I found someone who repaired the household appliances and repaired it The boot speed is slow It is actually the two capacitors on the board that are bulging If it is customer service, maybe I will directly replace the motherboard for you (the motherboard seems to cost more than 400).

The repair master said that the two capacitors are only 1 yuan, and it would be good to replace two, but the door-to-door maintenance will charge a total of 100, but it is much more affordable than after-sales.

I bought a Samsung product, and if there was a problem, I didn't actively help solve it, and I had to charge a high amount of so-called maintenance fees, and I had to spend it first (320+30) if I didn't count the parts, and I felt very uncomfortable.

Samsung TV,It takes many times to turn on normally,In this case, there may be a fault in the TV system or hardware。

After the customer's engineer arrives at the home, the TV will be inspected to find out the cause of the TV's failure.

If the TV is still under warranty,It's a natural fault,Brand customer service is responsible for the warranty,If the TV is out of warranty or a man-made failure,Then the user can only pay for repair。

What is the adaptability of Samsung LCD TV with a wide voltage, how can this be? Is your electricity environment not good? Is the voltage low? The power supply was not replaced during the last warranty! Temporary measures can be tried with a voltage regulator.

Current fluctuations.

Samsung LCD TV is a TV produced by Samsung Electronics, which mainly includes 9000 series, 8000 series, 7000 series, 6000 series, 950 series, 850 series, 750 series, 650 series, 610 series, 550 series, and 350 series sales in the Chinese market.

Development: In the LED tide, all armies are doing their best to take the lead in this new field. Samsung's performance is particularly noteworthy.

Samsung Electronics has a complete upstream and downstream LCD industry chain, independent core technology and strong financial support. Samsung Electronics began the research and development of LED TV as early as 2005, with an initial investment of 90 million US dollars and a registered capital of 30 million US dollars, Tianjin Samsung LED **** settled in Tianjin.

As the first major overseas production base of Samsung LED Co., Ltd., it specializes in the research, development and manufacturing of new electronic components (LED series products). In order to make effective use of this huge resource system, Samsung Electronics has set up a separate business department in charge of LED TVs to distinguish it from the conventional LCD TV.

Samsung has long looked forward to the broad market prospect of LED TV, and wants to use LED TV as a force to realize the transformation of the entire Samsung Group, and continue to develop advanced technology of LED TV, and accumulate scientific and technological research and development strength. From this point, it can be seen that Samsung wants to use the LED TV leader to achieve a gorgeous turn of the brand.

2.The automatic power on between the fixed * is related to the TV settings, press the [Project] button of the TV remote control (press the [More] button on the smart touch remote control, select [Project]), select the settings or [System] - [Time] - [Power on*] in turn, and try to turn it off.

Hope it helps!

The question was asked with the Snail TV remote control without a project button.

I didn't respond to my question.

There is also no option to adjust the power on and off time in the question settings.

Hello dear, there are reasons for:1The failure of TV parts leads to automatic restart, such as poor contact of the motherboard circuit, moisture leakage of the high-voltage package, and unstable power supply of the motherboard.

2.The software is incompatible with the system and causes the system to crash, resulting in automatic restart, it is recommended to check the recently installed software, and delete it to solve the problem. 3.

In addition, if the CPU or graphics card is overheated, dusty, or the wind beam and land fan fails, the hardware in the chassis should be cleaned and dusted regularly, or replaced or installed with a cooling fan to alleviate it.

Samsung TV automatically restarts, it is recommended that you:

1.Check that both ends of the power cord are securely connected.

2.Check whether the power supply at home is normal and whether other electrical appliances can be used normally.

3.If the above operations do not solve the problem, please report for repair through Samsung's official website, and Samsung maintenance personnel will come to check and deal with it.

The first thing to consider is the question of setup.

Open the menu and have an option to set up the auto-boot. It can be directly restored to factory settings.

The voltage is unstable and causes a restart.

When the voltage is unstable, the TV will automatically restart for protection. In this case, you can buy an adapted voltage regulator.

This fault phenomenon is called "intermittent black screen", and there are two common points of failure:

1) Faulty backlight circuit.

The most prone to failure in this circuit is the boost coil, which is generally a problem of poor contact, and the failure rate of the boost coil itself is very low (when welding, the surface paint of the enameled wire is not depainted, and the real welding point is only the wire head part), and it can be re-welded;

The reasons for the automatic restart and the workarounds are as follows:

1、System failure:There are bugs or errors in the system itself that cause automatic restart,It is recommended to restore the system of the TV to factory settings or upgrade to the latest version,You can go to【Settings】-System Settings】-System Restore】or【System Upgrade】To solve the problem;

2. Automatic restart caused by failure of TV parts, such as poor contact of the motherboard circuit, moisture leakage of the high-voltage package, unstable power supply of the motherboard, etc., can only contact the after-sales service of the TV for comprehensive testing and warranty of the TV.

Hello! Excuse me, what is the reason for the sudden shutdown of Samsung TV when it is turned on?

Kiss. Hello, I'm glad to answer for you: What is the reason why Samsung TV suddenly shuts down when it is turned on?

Answer:What are the reasons for the sudden shutdown of Samsung TV when it is turned on are as follows: 1、It may be that the electric energy in the TV is not welded and the self-shutdown is caused by it; Generally, it is necessary to check the solder joints at the switching power supply and line scan output circuit of the TV, and you can focus on checking the components with larger volume and higher temperature; After finding the virtual solder joint of the TV, you can re-solder it with an electric soldering iron.

2. It may be that the X-ray maintenance power route of the TV is faulty, which causes the TV to turn off by itself; The voltage of the X-ray protective pin is measured, and if there is an abnormality, it is judged to be a fault and needs to be replaced. 3. It may be that the TV display is widened and overvoltage maintenance causes the TV to turn off by itself; When the voltage value of the TV's power supply is higher than the set value, the overvoltage protection circuit will work, and the switching power supply of the TV will stop working, resulting in automatic shutdown. 4. It may be that the TV display overcurrent maintenance, as long as the current carrying power route of the TV causes the current to be too large for some reason, the overcurrent protection of the TV will work, so that the TV power circuit will stop working, and it will automatically shut down when it is bright.

5、Most TVs are not affected by external factors,But the hardware inside is faulty and the trip is shut down,Non-professionals recommend contacting the after-sales service of the TV for maintenance。

Samsung TV turns on automatically, it is recommended that you:1The TV is powered off before it turns off (ex:

Unplug the power plug, power outlet power failure, power outage, etc.), it is normal for the TV to automatically turn on after powering on. 2.The fixed time automatic power on is related to the TV settings, press the [Project] button of the TV remote control (press the [More] button on the smart touch remote control, select [Project]), select the setting or [System] - [Time] - [Power on Timer] in turn, and try to turn it off.

3.If the situation you encounter does not match the above description, or the TV automatically turns on from time to time, please report for repair, and Samsung maintenance personnel will come to check and deal with it.

Samsung TV malfunction is generally caused andHow to deal with it:

1. Check whether the TV remote control is short-circuited, leakage, and trigger the power button from time to time, resulting in automatic shutdown and automatic power on, you can take out the battery of the remote control and then observe whether it will automatically shut down and automatically turn on, or replace the remote control of the same model to use, you can solve the problem.

2. Hardware failure of the TV: the switch of the power button of the TV is short-circuited, the internal circuit is short-circuited, and other parts are cleared.

The general reasons and treatment methods for Samsung TV to turn on after automatic shutdown:1、First check whether the internal TV remote control is short-circuited、Leakage and trigger the power button from time to time to cause automatic shutdown and automatic start,You can take out the battery of the remote control and then observe whether it will automatically shut down and automatically turn on,Or replace the remote control of the same model to use,It can be solved。 2. Hardware failure of the TV:

The switch circuit of the power button of the TV is short-circuited, other internal circuits are short-circuited, and other parts are damaged, so it is recommended to contact the after-sales service of the TV for comprehensive testing and warranty of the TV.

The recent malfunction of Samsung TVs is that when there is a signal, the remote control turns off and then turns on automatically.

Here's why.

When there is no signal, the remote control can be turned off.

Maybe there is a problem with the motherboard, take it apart and check it. Thank you!
