Type C: What is the reason why the slave power supply is normal but there is no screen after the mas

Type C The slave power supply is normal after the master-slave is connected, but I don't have a picture, it may be a problem with your current display, it may be that your current screen is not recognized, so this situation occurs, thank you.

This situation is likely to be incompatible, and it must be noted that the two should not match, so this situation will occur.

If the Typec host is connected, but there is no picture, it may be that the display is broken, and you can find a maintenance person to check it.

There is no picture, it is very likely that there is a problem with the picture tube, so there is no picture.

If the connection is normal, it means that the data can be connected, and if there is no picture, it may be the reason for the software itself.

How to escape from prison when the latter of the woman's family goes from normal to no picture in the electromechanical park? It may be caused by a malfunction at the connection signal.

Hello, this situation should be a problem with the data transmission line, unable to make the data transfer in.

If this aspect is not normal, then it may be that there is a problem with your monitor, or there is a problem with your data cable, which is generally a problem in these two aspects.

If your device does not have a convenient power supply from the back, it is recommended that you try a different cable.

Hello, I think it may be that the master-slave machine is out of order, and it is recommended to take it to the repair shop for repair.

After connecting from the host, the power supply of the machine is normal, but there is no screen, then it is possible that the method is wrong when you connect, right?

Here's how to solve the problem:

1. Check whether the power supply and restart button have a physical fault, the most common is that you can't get up when you press it, any one of the two buttons has this problem, which can cause the computer to fail to start normally. The only solution is to send the chassis for repair or replacement, because the chassis is integrated into the chassis, which is difficult for ordinary users to repair.

2. Open the case, unplug the motherboard BIOS, wait for a while, and then press it again to see if the computer can run normally.

3. Unplug all the connection wires between the motherboard and the chassis, and touch the power control pin of the motherboard with a screwdriver (because there are many pins, please refer to the motherboard manual for the confirmation of the power control pin, don't touch it, it will burn the motherboard), if it is turned on normally, it proves that it is a problem with the boot and restart buttons of the case. The workaround is the same as above.

Overview

A computer monitor is also commonly referred to as a computer monitor or computer screen. It is the most important part of a computer besides the CPU, motherboard, memory, power supply, keyboard, and mouse. There is no unified concept of computer monitor, but the understanding of it is mostly the same, as the name suggests, it should be a display tool that displays a certain electronic file on the screen through a specific transmission device and then reflects it to the human eye.

Answer: The solution to the computer is turned on normally but the screen is not screened: 1. Check whether the power cord of the computer is connected; 2. Check whether there is any excess metal in the main chassis or observe whether the motherboard is in contact with the chassis; 3. Maintain the power switch line; 4. Replace the power supply.

The icon disappears when the question is turned on. I can open the background, but the desktop does not show it.

Ask a desktop wallpaper.

Questions are only displayed in the run bar, there is nothing on the desktop.

Answer 1: If the fault persists, open the task manager (press the "Ctrl+Alt+del" key combination to open), click "File" and "New Task", enter "explorer" in the "Create New Task" dialog box that opens, click the "OK" button, and wait a while to see the desktop icon.

The screen went black directly after the question key combination.

Questions are lit up.

It's the problem of the monitor crashing,You pull the power cord of the monitor,It's equivalent to letting the display restart and return to its place,There are chips in the display,It will also crash like the host.,It's okay.,Keep using it.。

It may be the fault of the memory card, graphics card, CPU, motherboard, etc., at this time, we only need to plug and unplug these hardware, or replace it again, and try to find the cause one by one.

1. The power supply is damaged, and the power supply cannot provide power support, so that part fails to shine;

2. The signal line (cable) is damaged, and the signal of the previous board cannot be transmitted to the next board, so it is not displayed;

3. The control card is set incorrectly, the number of points set on the control card does not reach the actual number, and the signal of the excess part is not displayed;

4. The LED LED in the display screen is damaged, or there is a problem with the wiring or the power supply hardware.

I have the same symptoms as yours. Changing the monitor is normal, which proves that the host is fine. However, in the original display, the image is not displayed if the signal light is on and the signal light is off.

There are probably the following reasons:1. Poor contact of the connecting wires; 2。The interface is oxidized; 3。The motherboard slots are dusty; Probably according to the above problems can be solved!

Look at your cable, there may be bad contact, otherwise it's a graphics card.

It's possible that there is a problem with the monitor or the graphics card of the host computer.

Problem analysis: If the computer is powered on (the power indicator is on) but there is no signal or the screen shows "no sighal", it is generally due to poor contact due to loose or oxidized memory modules, or poor contact with the display data cable, or damage to the memory, graphics card, display or data cable.

Handling suggestions:1If the monitor is powered on but no signal is displayed, turn off (if the short press of the power switch is invalid, press and hold the switch until the power indicator goes out or directly unplug the power cord) Power off the case, replug and unplug the memory module, and wipe the gold finger with an eraser in one direction (the back of the thumb fingernail is also fine), if possible, it can also be installed in different memory slots, and then turned on after installation (before operation, you should also touch the wall with both hands to release your static electricity or wear anti-static gloves).

If you don't know how to operate, then it's simple: slap or kick the chassis once or twice (pay attention to the location: the front of the shell on the left and right sides of the chassis that has no interface at the back; Attention Tract:

Don't push too hard, and certainly don't be weak). The above may need to be repeated, and if it doesn't work, you need to replace the memory module. If you have more than two memory modules, you need to test them one by one.

2.If the above operations do not work, turn off the power and turn on the chassis, reinsert the graphics card, and plug in the data cable between the monitor and the graphics card. If it still doesn't work, consider that the cable or graphics card is damaged, then replace it with a new one.

3.If the monitor is not powered on (the indicator light is not on), check whether the power switch is turned on, then check the back of the monitor, plug the power cord connected to the monitor upwards (the power cord can be replaced if possible), and check whether the other end of the power cord is powered on to the outlet.

4.If the display can be displayed when connected to another monitor or the display of this machine is connected to another normal host and still cannot be displayed, it means that the monitor is damaged and needs professional repair.

1. The power supply is damaged, and the power supply cannot provide power support, so that part fails to shine; 2. The signal line (cable) is damaged, and the signal of the previous board cannot be transmitted to the next board, so it is not displayed; 3. The control card is set incorrectly, the number of points set on the control card does not reach the actual number, and the signal of the excess part is not displayed; 4. The LED LED in the display screen is damaged, or there is a problem with the wiring or the power supply hardware.

Questions. My son smashed a f and the screen went white.

It needs to be repaired.

The hardware is damaged.

Question, do you need to change the screen:

This needs to be detected with a device!

It's hard to say. Questions.

The screen t smashed out a bright spot.

Maybe the screen is broken!

Questions. <>

That's it. Having a dot on the screen is a bad place. Do I need to change the screen?

If you can use it, you can use it first, but if it's serious, you need to replace it.

Questions. Light white screen. It can't be used.

Then replace it.

Wipe the metal feet of the graphics card. Add some puddle fat and try it. See if the graphics card capacitor has exploded.

1. It may be that the monitor is not powered on, check whether the power switch and power adapter of the monitor are powered on;

3. It may be that the host graphics card is loose and there is no screen display, try to disassemble the computer and fix the graphics card again;

4. It may also be that the display itself is faulty and needs further maintenance after sale.

3. There is a problem with the memory, or it is a poor contact.

4. There is static electricity on the motherboard, resulting in no response.

5. The discrete graphics card has poor contact or problems.

6. The motherboard is broken, or there is a problem.

Here's how to fix it:

1. If the light of the monitor is not on after the screen of your computer is black, but the light of the main chassis is still on, at this time, consider that the power plug of the monitor is not plugged in properly, or it has been loosened, just plug the plug back in.

2. If the light of the display is on, and the main chassis is also on, you have to consider another problem at this time, that is, it is possible that the transmission line is loose or broken, so try to replace it with a new one at this time.

3. The black screen of the desktop computer boot may not only be a problem with the power supply or plug, but also the graphics card of the computer host is loose, in this case, you need to open the computer case, get the graphics card down and wipe it, and then install it to try to see if it works.

Question: The monitor is fine, I tried it, I add the set-top box.

The graphics card light is also still on.

I removed the memory module and reinstalled it.

1. The screen is not lit, how does the landlord know that the host is "operating normally".

2. If the keyboard light, mouse light, host power indicator, etc. are normal after pressing the power button. The monitor does not display, and there is no prompt, and the color and brightness of the monitor light remain unchanged. It is recommended to forcibly shut down the computer (Chang'an boot button).

Unplug the power cord, dust off the computer, and use an eraser to wipe the gold fingers of each board, especially the memory modules.

3. It still doesn't work, it is recommended to replace the monitor.

What is the reason why the display screen is not lit up and the host is normal, teach you a trick to do it easily, it's too simple.

First of all, determine whether your computer has a beep similar to an alarm when it is turned on, if there is one, the display is not detected by the motherboard, if not, it is the problem of the display itself, call the manufacturer**.

Is there a row of English no signal output on the screen?,If so, are you installed with a separate GPU?,If so, don't plug it into the socket of the motherboard.,Plug it into the graphics card.。

Erase the memory module, if it doesn't work, if it's a separate graphics card, wipe off the graphics card, and then take off the button battery on the motherboard, pinch it off your fingers, and put it down, if it doesn't work, you can carry it to repair.

The memory module burned, hehe. You go and change the memory module, and by the way, check if there is anything wrong with the motherboard?? If the computer configuration is not very good, it is recommended not to play large online games or store large files, movies, etc.。 Otherwise, these problems are likely to occur.

The display prompts that there is no signal output, remove the graphics card, memory module and clean up the dust, and the CPU fan is better to clean up, which can generally solve the problem.

You see if there is something wrong with the graphics card, or the power supply, the memory module upstairs is burned, and you can see the picture, but you can't pass the self-test.

It is usually the oxidation of the gold finger in the memory, resulting in poor contact. There is no display caused by the power-on of the computer.

Unplug the power cord on the back of the case and press and hold the power button 5-6 times to release the residual charge. Then disassemble the chassis side bezel.

Plug and unplug the memory and replace the memory slots.

Re-energize the boot test.

1: The possibility of the system is very small, and the hard disk is the most suspicious: the gold finger of the interface of the hard disk power supply line group is oxidized, please wipe it with a cotton swab dipped in medical alcohol.

Wipe on both sides. In addition, it is also necessary to observe whether the socket is deformed and the contact is virtual. This is the point of the examination; Also, it is important to confirm that the signal line, i.e., the data line, is in good condition.

Change the mouth, change the line and try more.

2: The memory module graphics card is not very suspicious, but it should also be checked, eraser wipe the gold finger and remove dust.

3: No need to get to three, okay. Without.

How to troubleshoot the failure of the computer without display when it is turned on (check whether there is a bulging capacitor).

1. First of all, check whether the external wiring of the computer is connected, and plug in each cable again to see if the fault is eliminated.

2. If the fault persists, then open the main chassis to check whether there is any excess metal in the chassis, or a short circuit caused by the deformation of the motherboard, and smell whether there is a burning paste in the chassis, whether there are burned chips on the motherboard, and whether the capacitors around the CPU are damaged.

3. If not, clean up the dust on the motherboard, and then check whether the computer is normal.

4. If the fault persists, then unplug the reset cable on the motherboard and connect it with other switches and indicator lights, and then use the short-circuit switch to see if it can be turned on.

5. If you can't turn it on, then use the minimum system method, unplug the data cable of the hard disk, floppy drive, and optical drive, and then check whether the computer can be turned on. Then connect the above devices to the computer one by one, when connecting a certain device, the fault will recur, indicating that the fault is caused by this device, and finally focus on checking this device.

6. If the fault persists, the fault may be caused by memory, graphics card, CPU, motherboard and other devices. Then, use the plug-in method, swap method and other methods to check whether the memory, graphics card, CPU and other devices are normal, and replace the damaged devices if there are damaged devices.

7. If the memory, graphics card, CPU and other devices are normal, then discharge the BIOS, use the isolation method, place the motherboard outside the chassis, connect the memory, graphics card, CPU, etc. for testing, if the computer can be displayed, then install the motherboard into the chassis for testing until the cause of the fault is found. If the fault persists, you need to return the motherboard to the manufacturer for repair.

8. When the computer is turned on and started, the system BIOS starts to POST (power-on self-test), and when a fatal error is detected in a device in the computer, it will control the speaker to send out a sound to report the error. Therefore, there may be a fault that the power is turned on without displaying an alarm sound. If the computer is turned on and there is no alarm sound, the fault can be checked according to the meaning of the BIOS alarm sound to check the faulty device to eliminate the fault.
