What should I do if my Sharp TV freezes when I open the settings?

If you can still install and open the app, use this method:

After installation, it prompts "Completed Opening" after installation, and opens it directly.

The setting on the outside can't be moved, but it's still active in this setting, just restore the system here.

I bought a new TV for a few days and encountered the same situation as the landlord.,Solve it with this method.。

My TV has this problem too.

There are a lot of ways to brush up on the Internet, and I will summarize them with you. I did it the last resort, so you can try them one by one.

1.The upstairs method is not easy to use at my house. I've changed a lot of mouse, but I can't click on the settings. Link keyboard entry or freeze, and finally fail.

2.Various combinations of key engineering modes, K mode. I can't get in. I feel that this model of TV can't enter advanced mode.

3.Contact after-sales, and come up to replace the motherboard. **It's not cheap, and finally let him go with a door-to-door fee.

4.I received a post on the Internet saying that this situation will occur if you install the Wukong remote control and uninstall it. I don't remember pretending to be or not.

Ready to give it a try. You need to reinstall the Wukong remote control on the TV, and you can enter the settings and not crash. As a result, I found that the TV could not install any software again.

The query is a problem with the SD card, and the SD card needs to be formatted. If the SD card is write-protected, you can do the method, here is not inked anymore. Use a disk or SD card to re-open the software of the Wukong remote control, install it on the TV, enter the settings, and restore the factory settings.

Problem solving. Then remember to delete the installation file, so as not to install it again one day.

Hello, the reasons and solutions for the TV not turning on:

1. The TV cannot be turned on due to the failure to turn on the power supply or the power switch of the fuselage; You can check whether the TV is connected to the power supply, whether the power button is on, and if it is not turned on, it can be turned on and turned on to solve the problem.

2. It may be that the TV cannot be turned on when it is in standby mode; Check whether you have pressed the [Standby] button of the TV remote control to turn off the TV's screen display, so that the TV is in [Standby mode], you can press the [Standby] button of the remote control again to wake up the screen and return to normal.

3. The TV still can't be turned on after the above methods are checked, which is generally judged to be caused by the hardware failure of the TV, including power failure, short circuit or open circuit of the switch circuit, screen cable failure, screen failure, other circuit or component failure, etc.; It is recommended to contact the after-sales service of the TV for a comprehensive inspection and warranty of the TV.

If the TV is not connected to the power supply or the power switch of the fuselage is not turned on, you can check whether the TV is connected to the power supply, whether the power button is turned on, and if it is not turned on, it can be turned on and turned on to solve the problem; 2 4 The standby state may be that the TV cannot be turned on when it is in standby mode, check whether you have pressed the [Standby] button of the TV remote control to turn off the screen display of the TV, so that the TV is in the [Standby state], you can press the [Standby] button of the remote control again to wake up the screen and return to normal; Jingdong recommends advertising for you according to the content of the article, Zimiaodi, suitable for universal LCD TV, remote control, universal all, Skyworth, Hisense, Haier, Konka, Changhong, Skyworth, general, meta view, 3 4, there is a problem with the power board, the power board is abnormal, or the switching power supply module (IC) is abnormal, and there is a problem of parts failure inside the TV; 4 4 hardware failure after the above methods to check the TV still can't turn on, generally judged to be caused by the hardware failure of the TV, including power failure, switch circuit short circuit or open circuit, screen cable failure, screen failure, other circuit or component failure, etc., it is recommended to contact the after-sales service of the TV for a comprehensive inspection and warranty of the TV.

Questions. The power is also turned off.

It's the same with my TV at home, and it can't come anywhere.

Need to find a maintenance master.

Lift the lid of the TV series.

The Sharp TV won't turn on.

Sharp LCD TV can't turn on solution:

1. Confirm whether the red standby light under the TV is on before turning on, and check whether the power plug of the TV is stable and whether the power socket is powered.

2. If the standby light of the TV is on, but the screen is not displayed, it may be caused by being in standby mode, use the standby button of the remote control to wake up and start up.

3. The standby light is on but cannot be turned on, and there is an abnormal sound when it is turned on, which is preliminarily judged to be a TV failure.

4. TV faults such as: switching power supply failure, power cord failure, screen failure, poor screen cable contact, motherboard and other parts failure, etc. The above TV faults need to contact the TV after-sales personnel for maintenance to solve the problem.

Questions. The indicator light is not on.

Is that a socket problem, can you light up if you change the socket.

1. It may be that the TV cannot be turned on when it is in standby. Check whether you have pressed the [Standby] button of the TV remote control to turn off the TV's screen display, so that the TV is in [Standby mode], you can press the [Standby] button of the remote control again to wake up the screen and return to normal.

2. There is a problem with the picture tube and the picture tube needs to be replaced.

3. The TV turns on the power indicator normally, and it can't be started with the remote control, which may be that the main voltage is abnormal. It is a poor contact caused by desoldering of the main voltage circuit of the power supply.

4. If it is caused by hardware failure, including power failure, short circuit or open circuit of switching circuit, screen wiring failure, screen failure, other circuit or component failure, etc., it is recommended to contact after-sales service.

You first check whether the TV power light is on, and if not, try to change the power cord.

Sharp TVs can't watch flat panels.

Start by checking if your home's outlet is a point. If there is no electricity, you can try changing the plug, if it still doesn't work. That could be a problem with the power supply motherboard.

1. The main power supply is faulty. The power supply that may be supplying the whole machine may be faulty. 2. It is possible that the child lock designed by Sharp TV to prevent children from turning on at will has taken effect.

3、Sharp TV is in standby mode,So it can't be turned on,For example, the user mistakenly pressed the standby button of the TV remote control,Make the TV in standby。 Suggested solution:1、Make sure that the TV has been connected to the power supply,And turn on the power switch on the fuselage,It can return to normal。

2. It is suspected that the problem is in the standby circuit or pre-amp. Indicates that the circuit is not working. The power supply of the standby circuit has also arrived, but there is no power supply output, so the problem should be in the standby circuit, the standby voltage is measured, and there is no abnormality, and the replacement is not good.

3. Generally, the probability of multiple faults occurring at the same time is very small, and it is analyzed and found one by one according to the order of main power supply, line scan, and main channel. 4. You can press the [Standby] button of the remote control to wake up the TV and return to normal. Use the power button of the remote control (generally red), or press the standby button on the TV (standye), press the channel + -ch+, ch-) without the key to see if it can be turned on, if it can't be turned on, it is a problem inside the TV, and you need to find after-sales service to repair it and contact after-sales or maintenance workers to repair the faulty circuit.

1. If it is an online smart TV.

machine, mainly check whether the software has been installed recently, and the system is incompatible and conflicted, resulting in a crash, and generally deleting it can solve the problem.

2. System problems: Regardless of whether it is a smart TV or not, if there is a bug or error in the system carried by the TV, it will cause a crash; Generally, you can restore the TV system to factory settings.

If the system can be upgraded, try to upgrade to the latest version to solve the problem.

3. Hardware problems: the failure of the internal parts of the TV, the existence of short circuits, the leakage fault of the high-voltage package, etc., may cause the TV to crash, it is recommended to contact the after-sales service of the TV for a comprehensive inspection and warranty of the TV.

TV is a relatively intelligent product,It is more commonly used in our actual life,And I believe that everyone is familiar with this kind of product。 Of course, there will be various problems in the use of TVs,And the phenomenon of not being able to turn on is what we are often prone to encounter,So next,The author will introduce to you what is the reason why the TV can't be turned on,And several common brand TV solutions。

1. What is the reason why the TV can't be turned on?

1.The power cord is not properly connected or the power adapter has no voltage output.

2.There is no voltage output in the switching transformer in the TV, and the peripheral electronic components are abnormal.

3.There is an abnormality in the power board or an abnormality in the switching power supply module (IC).

4.The remote control is not powered or damaged.

5.The keys on the control panel of the TV are damaged or leaking.

6.There is an abnormality in the motherboard and CPU circuit.

7.There is a short circuit phenomenon in high-voltage plates, Y-plates, buffer plates, etc.

Second, the solution of several common brand TVs.

1. Skyworth TV:

1) Check whether the 300V power supply of the power supply board is normal, if not, please check the front-end circuit of the power supply, such as transformer, voltage regulator IC, rectifier diode, filter capacitor, etc.

2) If there is 300V power supply, please check whether the power strip 5V, 24V, 12V is powered; Please check the small resistors, capacitors, etc. around the switching power supply. If so, check the motherboard, CPU circuitry, etc. further.

2. Sharp TV:

1) If it cannot be turned on normally, first of all, it is necessary to suspect that the switching power supply circuit and the remote control system control are on. Shut down the corresponding circuit. So when the fault occurs, check the power supply pin 52 of microprocessor N701 (M50436-560SP) has normal +, and press the standby button on the remote control, the voltage on the N701 remote control signal input pin 5 fluctuates, indicating that there is a remote control signal input to the microprocessor, but its power switch pin 9 does not have any signal output, check the reset pin 27 again, the voltage is only +, deviates from the normal value, check the standby power supply circuit and the start circuit, and the voltage on the C834 is measured to be only + normal should be +1ov or so) is low.

2) Check the capacitor C834, and find that its leakage and capacity are reduced, so that the standby power supply voltage is too low, and the starting circuit V810 of the microprocessor can not provide a normal reset voltage to the pin 27 of N701, so that the microprocessor can not work normally, resulting in the aforementioned fault phenomenon, replace a new component of the same model, power-on test, and troubleshooting the TV.

If you can't turn on the machine, you can find Sharp's after-sales service, if it is out of warranty, you can find a home appliance repair shop, and you will know what the reason is only when you need to test it.

Hope, thank you.

Got it, go find a repair shop.

Sharp TV freezes when you open the settings. What to do? 1. Poor system optimization.

Poor system optimization is mainly reflected in whether there is too much software that is not needed on the TV. Take Haier TV as an example,In the native system of Haier TV,There are a lot of application software that we don't need on TV,These applications will not be used in the ordinary use of TV,But because it is software brought by the remote system,Most of them are set to start automatically at start,It will occupy a lot of system memory,So as the running speed and effect of TV。

Second, there are too many applications in the background, which affects the memory of the TV.

When it comes to background apps, there may be some users who don't understand it very well. In fact, to put it simply, a background app is an app that has been opened before, but because it has not exited the app, it is still in the background of the system while you are using other apps.

A part of the program that runs. With the increase of background applications, the memory of the system itself will become smaller and smaller, and after such a vicious circle, it will be easy to cause failures such as system failure or crash.

Third, the system collapsed and excavated too much garbage.

Due to the lack of good equipment maintenance habits, the system itself will lead to junk files and residual installation packages.

Hoarding of cached files, uninstalled software remnants, etc., which in turn affects the operation and speed of the system.

Fourth, the hardware of the device is damaged.

This point is easy to understand, that is, the hardware damage caused by the aging of the line, man-made external forces and other factors. When this happens, it is not recommended that you conduct a self-inspection, and it is necessary to contact after-sales service for safety reasons.

In the dispersion of the sun dissolved caused by the smart TV.

After the causes of crash and stuttering, I will briefly introduce the solutions for the first three points.

1、Normally,Before the smart TV crashes,It will be accompanied by a little system jamming or non-response,Therefore, when such a situation occurs,It is recommended to try memory cleaning,Clear out some unnecessary background processes,Or use one-click cleaning operation for your own TV,The purpose of releasing memory has been achieved。

2. In daily life, develop the habit of cleaning up frequently. Mainly for some useless installation packages on smart TVs, or residual files of uninstalled applications, etc.。 Users can use third-party applications such as want to watch assistant、One-click acceleration TV version、Xiaobai one-click cleanup and other third-party applications for daily maintenance of TV。

Regularly clean up the system junk and uninstall the infrequently used software to ensure sufficient system storage space.

3. If there are a lot of useless native system applications, you can also try to obtain root access and clean up the system applications, but it should be noted here that not all applications can be deleted. Improper deletion and removal operations may cause system crashes, so use them with caution.
