The iron curtain all in one screen is powered by the screen, but the boot display shows no signal an

The reasons and solutions for the display display no signal after the all-in-one is turned on are as follows:

1) The first reason: due to the formation of an oxide layer on the surface of the gold finger of the memory, resulting in poor contact between the memory and the memory slot, resulting in a black screen and no signal output

Solution: You can turn off the power first, turn on the all-in-one machine, dial out the memory, use the eraser to wipe the part of the gold finger (that is, where there is a copper sheet,) back and forth a few times, and then insert it back into the memory slot (or insert it back with another memory slot), and it's OK. Note that when inserting memory, it must be inclined to the motherboard at an angle of about 45 degrees (as shown in the figure below), insert it into the motherboard slot, and then press it into the circlip of the motherboard smoothly after inserting it tightly.

3) The second reason: that is, the graphics card's video memory is soldered, the performance of the main chip is reduced, the graphics card BIOS is disordered, and the control power supply IC is problematic, which will cause the graphics card to fail to work normally, that is, the graphics card is broken, and the computer will naturally have no signal output, and it will not be displayed, and the screen will be black when it is turned on.

The all-in-one screen can be lit, and the boot can show no signal, and then the screen goes black, indicating that the display screen itself is no problem.

Is your computer's motherboard powered on? The prompt is that there is no signal, and the motherboard is not up. Check if the motherboard is powered on.

Summary. The all-in-one computer is a new type of market product between the desktop and the notebook computer, which integrates the host part and the display part into a new form of computer, and the innovation of the product lies in the high integration of internal components. With the development of wireless technology, the keyboard, mouse and monitor of the computer all-in-one computer can be wirelessly linked, and the machine only has one power cable.

This solves the problem of many and complicated desktop cables that have been criticized by people. In the existing and future markets, as the share of desktops gradually decreases, it will certainly be even more precarious after the impact of all-in-one PCs and laptops and netbooks. The advantages of all-in-one machines are constantly accepted by people, and foreign countries have become popular as another highlight of their choice.

For all-in-one computers, different manufacturers have different names, whether they are Allinone, AIO computers, or screen computers. Among the users who participated in the survey, most users preferred the term "all-in-one computer". However, the proportion of users who choose the English names ALL INONEPC and AIO is small.

Dear, hello, I'm glad to answer your questions,,The all-in-one computer boots up and shows no signal and then the screen goes black,A: The all-in-one computer turns on and shows no signal and then the black screen Causes and solutions:1

The "no signal" prompt and black screen appear after the all-in-one computer is turned on, which may be caused by the following reasons:1Display issues:

The first thing you need to do is troubleshoot the all-in-one display itself. You can try connecting another external monitor, and if it does work properly, it may be an all-in-one monitor malfunction. 2.

Loose data cable: If the monitor is normal, it may be caused by a loose or damaged data cable. Please check whether the data cable connected to the all-in-one is loose or damaged, and replace the data cable if necessary.

3.Graphics card failure: The all-in-one PC uses a graphics card that is integrated with the motherboard, and if the graphics card fails, it may not display properly.

You can try taking the all-in-one apart to clean up the dust, check if the graphics card is loose or has other issues. 4.Memory module failure:

If the All-in-One PC's memory module is damaged or loose, it may also cause it to not boot properly. You can try removing the memory module and inserting it back in, or replacing it. If the above methods do not solve the problem, it is recommended that you contact the all-in-one computer after-sales service center or professional maintenance personnel for inspection and repair.

At the same time, it is recommended that you regularly maintain and clean the all-in-one to avoid damage to the device caused by dust and other factors.

It is caused by the sudden power failure and shutdown of your computer or the card before the shutdown, resulting in disk damage.

The black screen on boot has something to do with your improper operation before shutting down, right? For example: playing games, watching **, operating big things, and using the computer for a long time caused by the card, right? Or ** inappropriate things, failures don't happen for no reason, right?

Immediately after booting, press f8 to the advanced option to appear in the let go, select "the latest correct configuration" enter to repair, not yet press f8 to enter the safe mode to restore the system or reinstall the system (if the reinstallation is also a black screen, it is recommended to overhaul it, if you can enter the safe mode, it means that you have installed something inappropriate, uninstall all the inappropriate things before the accident, or restore the system or reinstall).

If there is a hardware, take out the motherboard battery and put it on the charge, plug and unplug the memory, clean the graphics card, check whether there is a problem with the hard disk, and if it doesn't work, just overhaul it.

It's really not possible to reinstall the system, if you can't reinstall it yourself, go to the maintenance there to find a maintenance person to help you, it should take a little to spend it, if you can't turn on the machine by any method, this is a sudden shutdown, caused by disk damage, one is to deduct the motherboard battery and put it down, one is to put it for a period of time in the boot to try, or you can't repair it.

BIOS battery discharge method: Discharge the CMOS memory through the jumper: pull out the jumper cap next to the CMOS battery, insert it into another pin for a few seconds, and then pull it back into its original position, or take out the CMOS battery, short circuit the positive and negative poles on the battery for a few seconds, and install the battery.

Summary. Hello dear Da, this situation may be caused by the following reasons:1

Graphics card failure: If you are using a discrete graphics card, then the graphics card may be faulty, and it is recommended to reseat the graphics card or replace it. 2.

Display issues: Try connecting your PC to a different monitor to see if there's a signal output, if the other monitors don't have a signal either, it could be a problem with the PC itself. 3.

Monitor wiring issues: Recheck the cable between the computer and the monitor to make sure the plugs are in good contact. 4.

Hard disk failure: If there is a problem with the hard disk, the computer will not boot normally, you can try to use another computer for hard disk testing. If you're not sure how to fix the problem, it's a good idea to seek help from a professional to avoid a more serious problem.

Are you there? I'm sorry to be here, the signal here is not good, and I haven't received it. Only now do I see it

Dear Da Chunshi, this situation may be caused by the following reasons:1Graphics card failure:

If you are using a discrete graphics card, then the graphics card may be faulty, and it is recommended to reseat the graphics card or replace it. 2.Display issues:

Try connecting your computer to a different monitor to see if there's a signal out, if the other closed-pants monitor also doesn't have a signal, it could be a problem with the computer itself. 3.Monitor wiring issues:

Recheck the cable between the computer and the monitor to make sure the plugs are in good contact. 4.Hard drive failure:

If there is a problem with the hard disk, the computer will not boot normally, you can try to use other computers to test the hard disk. If you're not sure how to fix the problem, it's a good idea to seek help from a professional to avoid a more serious problem.

The monitor shows no signal and a black screen, and the specific steps are as follows:

1. First of all, check whether the display signal line of the computer host and the host interface are loose. If the line is loose, just plug it back in.

2. Unplug the signal of the monitor and check whether the interface and the signal cable of the monitor are damaged. If the interface and line are damaged, replace it with a new display signal cable.

3. Check whether the display interface of the computer motherboard at the rear of the host is in good condition. If the monitor interface is rusty or the interface pin is damaged, the rust can be removed and the interface pin can be corrected.

4. Open the side cover of the host to check whether the interfaces of the motherboard are intact and whether there are rats biting the wire.

5. Check the memory next to the CPU of the computer motherboard, and whether the memory slot is firm. If it is loose, reseat it.

6. Check whether the interface between the independent graphics card and the motherboard is loose. If it is loose, please reinstall the graphics card.

7. If the computer host starts and hears a buzzer alarm, please remove the computer memory to check whether the memory is burned out.

8. If the memory is good, please erase the metal part of the memory with an eraser.

9. After the computer host is checked, check whether the display input surface of the display is damaged. Mainly check whether the pins of the interface are deformed. If you find that the hardware settings are damaged, you need to replace them or go to a professional repair point to repair them, and the problem of no signal on display is solved. <>

This could be caused by a problem with your monitor, computer, or cable. First, you can try restarting your monitor and computer aggressively. If the problem persists, you can try the following:

1.Check if the cable is loose or damaged. You can pull the cable out of the computer and the monitor and check for bending or breakage.

2.Try changing the cable. If you don't find a problem with the cable after checking it, you can try replacing it with another one to see if it improves.

3.Check your computer and monitor settings. Make sure that the computer and monitor settings such as resolution, refresh rate, and color depth match, if they don't, it may result in a black screen with no signal.

4.Check your computer's motherboard and graphics card. If other methods don't work, maybe there is a problem with the computer motherboard or the display card, resulting in the failure to output the signal normally.

It is recommended that you contact a professional maintenance personnel to solve the problem. In short, if your monitor has no signal black screen problem, please first check whether the cable is in good contact and check the relevant settings. If you still can't fix the problem, seek professional help.
