Why does the TOSOT fan turn off automatically as soon as it is turned on?

This can only be known by inspecting the machine on a case-by-case basis.

The original black screen on boot is due to a lot of things:

When we turn on the power of the host, the power light is also on, but the display is black, and there is no display or something similar to none.

Hints of signals.

1. The host does not start at all. Solution: Check if the wire plug is plugged in properly.

2. Is the power supply of the host broken? Solution: Replace the power box.

3. The CPU does not work if the contact is not good. Solution: Remove the fan and heatsink and pull out the CPU to clean up the dust, and then put it back in.

Note: The CPU has positioning, and it cannot be hard put in).

4. The signal of the bad host of the graphics card is not displayed. Solution: If your motherboard has a built-in graphics card, remove the discrete graphics card first.

Then connect the monitor cable to the motherboard's built-in graphics card and try to turn it on. No, try changing the graphics card.

1), discrete graphics card poor contact (2), discrete graphics card cheat oxidation (3), high-end discrete graphics card may be electric.

The source power supply is insufficient (try to replace the high-power power supply) (4), the independent graphics card slot is too dusty (the solution is basic and inside.

The deposit note issue is pretty much the same). 】

5. The memory module is faulty. Solution: Pull out the memory stick, use a soft eraser to wipe the gold finger on both sides, and insert it back.

6. The motherboard is broken. Solution: Pull out the memory module, if the power starts, if it alarms, the motherboard and CPU are good, is the memory module bad.

The graphics card is bad, replaced.

7. The system is broken. Workaround: Reinstall the system.

8. It can't be turned on after updating. Solution: Shut down and then restart, keep pressing F8 to enter the Advanced Menu, and select Safe Mode.

After entering the Safe Mode desktop, uninstall all patches of the update, then shut down and restart, enter the normal mode, and turn off the update.

9. The motherboard is damp. Solution: Remove the hard disk, memory module, ***-ROM and bake in the oven at 35 degrees for 10 minutes.

Take it out and blow the dust off the motherboard with a tubing gun.

10. The monitor is not. Solution: The power cord is not plugged in and reseated again.

12. Static electricity appears on the motherboard. Solution: Power off the main computer first, then find this button battery on the motherboard and take it out.

Come on, leave it for a minute. Then put it back in and turn it on.

None of the above will turn on or show up. Try to do it.

Reasons for the automatic shutdown of the electric fan after it is turned on:

1. The possibility of problems with the circuit board is relatively large;

2. The possibility of capacitance is relatively small.

If it is a circuit board problem, the circuit board needs to be replaced** more expensive, generally within 100 yuan.

Precautions for the use of electric fans:

1. Desktop and floor-standing electric fans must use three-core plugs and sockets with safety grounding wires; The ceiling fan should be installed at a higher position on the ceiling and can be installed without a grounding wire.

2. The fan blade of the electric fan is an important component, and it must be protected to prevent deformation during installation, disassembly, scrubbing or use.

3. When operating the switches, buttons and knobs of various functions, the action should not be too violent or too fast, nor can two buttons be pressed at the same time.

4. The speed control knob of the ceiling fan should be rotated slowly and sequentially, and should not be rotated in the position between the gears, otherwise it is easy to make the ceiling fan heat up and burn in.

There was a problem with the line.

1. The fan is referred to as the electric fan, called the fan in Hong Kong, and the fan fan in Japan and South Korea, which is a household appliance that uses a motor to drive the fan blades to rotate to accelerate the circulation of air, mainly used for cooling and relieving heat and circulating air. It is widely used in homes, offices, shops, hospitals, hotels and other places.

2. Put on the ground = floor fan; wall-mounted = wall sash; On the roof = ceiling fan, roof fan; on the table = table fan; There are also turning fans; exhaust fans; Air conditioner fan, etc. Ceiling fans are the windiest and are used in public places; Wall fans do not take up space; Floor fans are used in places that are not moved often; The table fan and the turning fan are easy to move; Exhaust fans are used in kitchens and bathrooms.

3. Structure: The electric fan is mainly composed of fan heads, fan blades, grilles and control devices. The fan head includes an electric motor, front and rear end covers, and a moving head air supply mechanism.

If it is the warranty period, contact the after-sales service to report for repair, because the circuit board is faulty, you can change the circuit board of a system type.

It's not difficult to do it yourself, buy a circuit board on the Internet, and replace it yourself.

You can also go to the maintenance department that repairs household appliances and let the master repair them.

If the main control board software fails, it is recommended to contact after-sales service for processing.

Poor wire contact, go to a dealer.

Okay, you're sure it's a problem with the control board, just change the board.

Is there a timer switch? Maybe there is some leakage protection switch. or thermal protection switches.

Obviously, the problem is with electricity!

If it's a hardware problem with the memory, it's a blue screen!

There are two possibilities for you:

1.If you have a problem with the power strip, try another one.

2.If it still doesn't work, it's a computer power supply problem, look for a repairer.

This is very serious, and you have to deal with it quickly, otherwise you will be depressed one day when the computer burns out.

CPU fan does not have thermal conductive silicone or fan failure, when the fan belt is just turned on, the fan belt does not move, and there will be a ZZ sound when it rotates very slowly, causing the CPU temperature to exceed the warning temperature, the computer will automatically shut down and be in a protective state, after turning on it many times, the CPU fan will be improved, the speed is faster, and the computer can start normally

So my advice is to check the CPU fan right away

It is estimated that the memory module is incompatible, or burned out, and the life is a problem.

Problems with the power supply fan, change the fan.

The fan does not turn.

2.The power supply is unstable or insufficient.

3.The system crashes and the system needs to be redone.

There are many situations, you have to make it clear, it may be the above, it may be toxic, it may be a hardware connection problem, it may be a software conflict, it may be a motherboard problem, or it may be that the hard disk is damaged and cannot read the ......The most useful thing is to check the line first, and then change the hard disk from the system if the progress of the system is slow, and the system is still after the system, change the motherboard, and be careful whether it is a problem with the power box.

Make sure the power cable and chassis hardware are plugged in securely, if you press power on and there is no response at all, it is estimated that the power supply or other hardware is broken.

Tell you that many Intel's high-heat CPUs have temperature control protection function. Examples include Pentium D and Pentium 4.

There is nothing wrong with your CPU fan itself, it may be that one of the four corners of the CPU fan is loose, and it is recommended that you check the fixation of the fan first. If there is no problem with fixing, remove the fan to check whether the top of the CPU is in good contact with the copper sheet at the bottom of the fan, and check whether the layer of heat dissipation silicone coating between the CPU and the fan has fallen off and disappeared. (First make sure your fan is revving high enough).

1。If that's the case, you can first see if the temperature of the CPU is too high, it must be that the fan and the CPU are not in contact with each other, or the fan is broken, especially in summer.

2。Power supply problems to see if the voltage is unstable to the computer restarts.

3。There is a problem with the memory: (1) The memory is not plugged in properly. (2) The memory has been corrupted.

CPU overheating. If you have a desktop, change the fan. If you have a notebook, go to customer service to open it and clean it!

It can also be a virus that causes the CPU to overheat. It is recommended to recover in its entirety!

It's the whole plate, not just the C drive.

It's not that the electricity is not plugged in properly! It's just that the timing is not adjusted! Otherwise, just take it back and get a new one!

The electric fan will automatically shut down after turning on, and the possibility of problems with the circuit board is relatively large, and the possibility of capacitance is relatively small.

If it is a circuit board problem, the circuit board needs to be replaced** more expensive, generally within 100 yuan.

If the capacitor is broken, you can replace a few pieces of the capacitor, and the repair cost will not exceed 20 yuan.

Mine is also a Midea fan, but also slept halfway to be woken up by the heat, found that the electric fan was in a shutdown state, pressed to turn on and worked for a few seconds, and then automatically turned off the light, shut down, and now it has not been repaired, and the repairman has no choice.

.FTS30-6AR, change the capacitor of the fan, it is invalid and does not stop shaking the head without starting, check that the rotating motor is not broken, it is estimated that the integrated circuit board is broken, so the maintenance continues to be used.

I also have one of these fans, and the same goes for shaking my head and clicking on the line cut, which could be that the integration is broken.

You can test it out; If it doesn't work properly, if it can work normally, it means that there is a problem with shaking the head, you can disassemble the shaking head to see if there is anything stuck in the gear, it should not be a big problem.

My Midea electric fan FTS30-6AR also encountered this problem, and the starting capacitor next to the fuse was replaced. Later, I replaced the capacitor on the back of the motherboard, and the problem was solved.

It is the answer to the words of "Tenjin Tianshen". My fan is also this problem, I went to repair it today, and it was pitted by the Midea after-sales center. It cost 40 yuan to change the capacitor, NND. That big, rectangular capacitor inside is probably rotten. It would be nice to change one.

That big, rectangular capacitor inside is probably rotten. Try another one.

This should be a matter of the quality of beauty, and mine is the same!!

The overheating protection of the electric fan will not be automatically turned on, and it needs to be turned on manually.

FS40 8AR electric fan shopping mall** about 280 yuan, with remote control, automatic shutdown after one second of boot, the possibility of the problem of the circuit board is relatively large, the possibility of the capacitor is relatively small, if it is a circuit board problem, the circuit board needs to be replaced** more expensive is generally about 100 yuan, estimated yuan, if the capacitor is broken, replace the capacitor a few pieces can be done, the repair cost will not exceed 20 yuan.

Mine is plugged in to the electric fan to blow the air, press the shake to stop, return to the power-on state, and replace the capacitor of the 1uf method behind the control board. FYI.
