How to repair and deal with the heat of the machine?

Regarding the heating of the mobile phone, it will directly lead to the burning of components, which has a great impact on the performance of the mobile phone, especially when playing games, such as the Glory of Kings This kind of large-scale game, the second mobile phone will be hot after playing for a while, and the mobile phone will appear stuck. In order to avoid the phone getting hot, do not install a low-quality phone case, which will adversely affect the heat dissipation of the phone. Do not use your phone in direct sunlight or for long periods of time while charging, and do not play with your phone while charging.

If the phone keeps restarting, if there is a virus in the phone, the software is not compatible, or the battery installation is not stable, it will keep restarting. For some non-original batteries, there may be a situation where the size and specifications do not match completely, and a small piece of toilet paper can be filled to assist in fixing the battery. If it is because the mobile phone installs the software to restart, you can uninstall the incompatible software or restore the factory settings to try, if there is still such a situation, it is recommended to re-flash the phone.

When the mobile phone is running, the mobile phone processor memory is in the computing state, which will produce heat dissipation, and the mobile phone screen will also produce a certain amount of heat when it works for a long time, and there will be a certain amount of heating when the mobile phone is charging. In short, there will be a certain temperature when using the mobile phone, especially when using some high-power functions, which is a normal phenomenon, please ensure heat dissipation, clean up the background, turn off the infrequently used functions of the mobile phone, and update the system in time.

When the mobile phone consumes power quickly, the mobile phone can be optimized, and the optimization method is as follows:

1. Please adjust the brightness of the screen.

Go to Settings > Show > brightness and decrease the value of the brightness progress bar.

The tail fork is flooded, and it can be cleaned with alcohol, or the boot button is short-circuited. It's more troublesome.

It's best to repair it, yellowing and blackening may mean that the resistance may be burned out, so it's best to repair it in advance.

The high-power resistor must be heated during normal operation, as long as it is not abnormally high heat and smoke, it is generally normal.

The figure shows obvious cracking marks, and in order to work safely, it is necessary to replace the equivalent power or equivalent power resistor.

That's going to be broken, prepare one.

If you have dropped your mobile phone in the past, it may be caused by a short circuit of the small IC, and you can continue to use it when the heating is over.

If the phone has not been dropped, it may be that the small IC is broken, just take it to the after-sales service.

But if none of the above methods work, it is estimated that the power supply is burned or the CPU is burned if it is not turned on. If it's a power supply, it's only a few dozen dollars to change the power supply.

4.If you are unlucky that the CPU burns, then it is troublesome, the CPU and font library of Samsung mobile phones are sealed, and the repair will be particularly expensive, and the effect of the mobile phone after repair is not particularly good.

It is recommended to try the following:1Charge with a wire charge for a while and try to turn on the 2

Take out the SIM card and try to power it on again. 3.If the problem persists, since the battery of this model is built-in, please bring the purchase invoice and repair card to the nearest Samsung service center for testing and processing.

Answer: Hello, after understanding, I learned that the main factors for Samsung mobile phones to not turn on are battery, mobile phone software, and hardware that will cause failure to turn on. It is recommended to do the following: 1. Replace a mobile phone battery of the same model for testing or send the battery to the nearest service center for testing (applicable to models with non-built-in batteries) 2. Try to turn on the SIM card and SD card for a period of time with a wire charge 3. Take out the SIM card and SD card at the same time, and then press the power button for more than 10 seconds to test whether it can be turned on.

If it still can't be turned on, there may be a problem with the system program or hardware, it is recommended to send the phone to the nearest Samsung service center for testing

Click Volume Up first, then click Volume Down after letting go, and then press and hold the right button after letting go.

iPhoneX dead restart is not the same as the mobile phone before iphone7, iphone7 dead can be restarted by pressing the power button + home button.

But the iPhoneX crash restart button is very troublesome, first the volume is increased and then the volume is decreased, and finally long press the right button to complete the restart.

After booting up press F8 to enter safe mode after exiting, after entering normal mode (Repair Registry). If the fault persists, please use the system restore that comes with the system to restore the problem until you did not have this failure.

The iPhone8, iPhone8 Plus, and iPhoneX released last year turned the iPhone7 set of combination buttons into an activation emergency SOS help function, and the iPhone8, iPhone8 Plus, and iPhoneX need to force shutdown and restart when they encounter a crash and get stuck has become a 3-step method of decomposition:

Step 1: Quickly press the volume + key;

Step 2: Press the volume- button quickly;

Step 3: Press and hold the power button until the apple icon appears.

Call Apple's official after-sales service and ask where the nearest repair shop is, you can test it for free.

The iPhone is heating up, which may be caused by the following conditions:

1) Charging state, in the charging state, the battery will generate heat, which is a normal phenomenon.

2) Playing large-scale mobile games or applications will occupy a lot of CPU resources.

3) Use the phone in the charging state, it is recommended to use it after it is fully charged.

4) Use the mobile phone in a closed environment, because the mobile phone is in a closed state, the heat cannot be dissipated, which will lead to serious heating, and it is recommended to use it in a well-ventilated environment.

5) Use your phone for a long time, such as talking for a long time, playing games, etc.

6) If the hardware of the mobile phone fails, it is recommended to go to the after-sales outlets for testing.

In the case of ignorance, it is not recommended to disassemble the machine by yourself and repair it blindly. so as not to cause unnecessary secondary damage. You can go to Xinmei United Block A in Pudong New Area to repair the mobile phone or go to the regular Apple after-sales service for maintenance, so that there is a guarantee that the physical mobile phone needs to be judged after on-site testing.

It is generally recommended to send the phone to the nearest service center for testing, and the service center will determine the specific problem, accessories, warranty coverage and repair of the phone based on the test results**.

Reason: power supply: power supply voltage is too high, power supply voltage is too low, power supply voltage asymmetry, three-phase power supply is unbalanced.

The load overheats the motor: the motor is overloaded, the dragged mechanical load is not working properly, and the dragged machinery is faulty.

The causes of overheating caused by the motor itself: open motor windings, short circuits in motor windings, wrong motor connections, and mechanical failures of the motor.

Poor ventilation and heat dissipation overheat the motor: the ambient temperature is too high, so that the air inlet temperature is high, the air inlet is blocked by debris, so that the air intake is not smooth, resulting in a small air intake, too much dust inside the motor, affecting the heat dissipation, fan damage or reverse, resulting in no wind or small air volume, no air hood or no wind shield in the end cover of the motor, resulting in the motor without a certain air path.

Treatment: Analyze the specific situation and troubleshoot and clear it according to the problem.

By listening to the sound and temperature, it is judged whether the bearing is working properly.

After inspection, whether it can be partially repaired, and whether it is a large area of short circuit or a short circuit that is difficult to repair is repaired.

Reasonable installation of low-voltage electrical appliances and protective devices, pay attention not to violate the relevant regulations, lay feed lines, and regularly inspect and maintain.

Motor]: It is a device that converts electrical energy into mechanical energy, converting electrical energy into mechanical energy. It consists mainly of an electromagnet winding or distributed stator winding to generate a magnetic field and a rotating armature or rotor. An energized coil is used to generate a rotating magnetic field and act on the rotor to form a magnetoelectric dynamic rotational torque.

According to the different power sources, it is divided into DC motors and AC motors, and most of the motors in the power system are AC motors, which can be synchronous motors or asynchronous motors.

The motor is mainly composed of a stator and a rotor, and the direction of the energized wire in the magnetic field is related to the direction of the current and the direction of the magnetic inductance line. The working principle is the effect of the magnetic field on the force of the electric current, which makes the motor rotate.

Repair Tips]:

Look: Observe whether there is any abnormality during the operation of the motor.

Listen: The motor should emit evenly and lightly during normal operation"Buzz"sound, no noise and no special sounds. If the noise is too large, including electromagnetic noise, bearing noise, ventilation noise, mechanical friction sound, etc., it may be a precursor or fault phenomenon.

Smell: By smelling the smell of the motor, you can also judge and prevent failures. If a special paint smell is found, it means that the internal temperature of the motor is too high; If a strong mushy or burnt smell is found, it may be that the insulation has broken down or the windings have been burned.

Touch: Touching the temperature of some parts of the motor can also determine the cause of the failure. In order to ensure safety, the back of the hand should be used to touch the motor housing and the surrounding parts of the bearing.

It's not too hot, it's not hot to the touch, it's not a big problem, if it feels hot, it's just two reasons: 1Power issues:

If there is insufficient voltage or lack of phase, these two items should be carefully checked; 2.Problems with electric motors: There may be overloads, short circuits between turns, or lack of oil in the bearings.

Overload and lack of oil are easy to check, and inter-turn short circuits should be carefully checked with bridges. Newly bought motors are not necessarily without problems.

If you are still in the warranty period, try to go to the after-sales service point for maintenance, and you can choose a cheaper maintenance point after the warranty period.

1.After the mobile phone is flooded, the heat is serious when it is used again, indicating that some components in the fuselage are corroded by liquid, resulting in impaired function, resulting in short-term use of heat.

2.There are two main situations of water ingress into mobile phones;

If the mobile phone penetrates into clean water, it will generally cause the mobile phone components to be short-circuited and burned when exposed to water.

The mobile phone is infiltrated with corrosive liquids such as salt water and alkaline water, which will corrode the motherboard components.

3.The damage caused by this is irreparable, and can generally only be solved by replacing the motherboard, which is costly.

4.Generally speaking, after the water enters, the battery should be deducted immediately, if it is a built-in battery, you can press and hold the power button to shut down urgently, and then put it in a ventilated and warm place to dry, if you have the ability, it is recommended to immediately disassemble the machine to clean up the liquid that enters, and then turn on the test after ten hours of thorough drying.

Xiaomi mobile phones are like this,You can do a survey,Mi1There are a few products that are still used until now (not broken),It's only been a few years,Look at how many are still using mi2,I'm not Mi Hei,But Lei Jun really doesn't make mobile phones with heart,Chinese entrepreneurs are doing pretense,Make money,Lack of conscience,I don't hack anyone,I admit that Xiaomi has made considerable contributions to China's smartphone industry,But Xiaomi mobile phones are really bad,It's not bad influence,But bad quality,

It's always been like this. I've used it for a long time and even the screen is hot, it's okay, take a break and play again.

In daily life, the washing machine may not be dehydrated due to long use time or improper use, which brings inconvenience to life;

The main reasons why the washing machine cannot be dehydrated are:

1. The clothes are placed unevenly, that is, the clothes are placed unbalanced in the washing machine, resulting in a situation where one side is light and one side is heavy, at this time, the washing machine will automatically adjust to a low speed, and then the dehydration effect is poor and cannot be dehydrated;

2. The drainage system of the washing machine is blocked. When the washing liquid in the barrel cannot be discharged, or the foam is too much and it is difficult to drain out, the water level switch of the washing machine cannot be reset, which will cause the dehydration function to be unable to be realized;

3. The safety switch on the top of the washing machine is damaged. That is, the linkage switch of the top cover of the washing machine is damaged, resulting in the washing machine not working normally during high-speed operation, and it may not be able to dehydrate;

4. The problem of clothing material. That is, if the clothes that are easy to absorb water are in the washing machine, if you choose to dehydrate at a low speed, it may cause the illusion that you cannot dehydrate;

5. The drain switch is damaged. That is, the normal drain switch is damaged, causing the water level of the washing machine to not be reset, and the dehydration procedure cannot be completed.

Common solutions for washing machines that can't be dehydrated:

1. If the clothes are uneven or the texture of the clothes is not good, it is recommended to put the clothes in the washing machine flat, and if the texture is easy to absorb water, the high-speed dehydration mode should be selected;

2. Check the drainage system of the washing machine, if the drainage valve is blocked, the drainage valve should be dredged, the drainage filter should be removed to clean, the drainage hole should be flushed, and the dirt should be removed; If the drain switch is damaged, it is recommended to contact the official after-sales service directly for on-site maintenance;

3. In the process of dehydration of the washing machine, try to avoid opening the top cover, so as not to cause damage to the top cover linkage switch and affect daily use.

In the process of long-term use of the washing machine, the water filling port and drainage hole of the washing machine should be checked regularly to remove dirt so as not to affect the normal use.

There are the following reasons why automatic washing machines do not dehydrate;

1. The switch of the top cover is damaged, and the washing machine is not allowed to open the top cover because it is a high-speed action when dehydrating, so there is a linkage switch on the top cover, which will be automatically disconnected as soon as the cover circuit is opened. If it is damaged and dehydrated, it will not move!

2. The drain level switch is damaged, dewatering is a procedure that needs to be carried out after draining, if the water level switch is damaged, you will not be able to enter the dehydration program!

3. The washing and dehydration of the automatic washing machine is completed by converting the gear at the bottom of the solenoid valve, and the damage of the solenoid valve will also make the dehydration unable to operate normally!

4. The computer control board is malfunctioning! It can only be replaced, because its control panel is covered with glue in order to be waterproof, and it is quite inconvenient to repair!
