Why won t my computer monitor turn on? 5

Generally, the monitor does not display 3 types:

First, you've already tried it! Detect memory. There is a lot of compatibility in the memory now, so sometimes you can't turn it on without touching the case! That's not a display issue.

The second type is the graphics card! Or the motherboard! There are a lot of compatibility issues too!

The third. It's the display itself.

Such an approach requires an alternative method to test!

You said above that the computer starts up and the monitor doesn't light up, in my case I think it's your computer is fine, and then the monitor has a problem! Let's move to a neighbor's house and give it a try!

If it doesn't work, change it to a new one! I trust Samsung more! I've been using 765mb for over 3 years!

Nothing is too much trouble! It's just that when you connect the monitor to someone else's host computer to repair the computer, the connection cable is broken! It's just a different cable.

No problem with the color!

There are causes of voltage instability, and there are also causes of hardware conflicts.

Is the power light on the monitor? If there is, it means that the monitor is fine.

The problem lies in the hardware, and there may be the following when a computer monitor does not light up

1. The power supply of the monitor is not connected or the switch is not turned on, and the display is damaged.

2. There is a problem with one or several parts in the host, and the general memory, graphics card, CPU, and motherboard problems will cause the computer to be turned on and not displayed.

3. The signal cable of the display is not connected or loose, resulting in no display.

If there is a problem with the display, you can borrow someone else's monitor to connect to the host and try it, if there is a problem with the hardware in the host, then you can only use the replacement method to try one by one, first try the graphics card memory, and then judge the CPU and motherboard.

Teach you the easiest way: unplug the cable behind the monitor, plug it back in, and see if it's okay?

If not, it's a hardware problem with your computer or a graphics card.

There's a problem with the monitor or the graphics card.

Your situation is most likely due to the following:

1.The power supply is insufficient.

2.The graphics card is not in good contact with the motherboard (only if your machine is a discrete graphics card, not an integrated graphics card).

Solution: For 1, you can choose to repair the power supply (about twenty or thirty yuan, but it is easy to fail again); buy an old power supply (probably a few dozens); Buy a new power supply (because the power supply has a great impact on the computer, so if you add silver, you should buy a better power supply, which is beneficial to the machine).

For 2, you can remove the graphics card, carefully wipe the gold finger and then reinsert it into the machine, taking care that the screws are properly tightened.

Specific implementation steps:

After turning off the power switch of the computer, first unplug the hard disk, optical drive and power supply, then remove the graphics card and memory module, wipe the gold finger and reinstall it, then check whether the monitor plug and the graphics card are plugged in tightly, then remove the battery on the motherboard, put it back on the motherboard after about half a minute, and finally turn on the power switch.

If the monitor is working properly at this time, turn off the power again, connect the hard disk and optical drive to the power supply, and then turn the power back on. If the machine is working properly, then it may be that your memory module or graphics card is not plugged in tightly, if the machine does not work, then the power supply is insufficient, and you can only change the power supply.

If the monitor still does not display the image at this time, but the case starts normally, then it is estimated that there is a problem with your graphics card, which is a hard fault, and you can only replace the graphics card or find someone to repair it.

Summary. The computer monitor may not turn on for a variety of reasons, you can follow the steps below to troubleshoot and solve: 1. Check the power connection:

Make sure the monitor power cord is plugged in and the outlet is working. Try replacing the outlet or power cord to see if that resolves the problem. 2. Check the signal cable connection

Check the cable between the monitor and your computer to make sure that the connectors, such as VGA, HDMI, DP, are plugged in and secure. If possible, try replacing the signal cable or using a different interface. 3. Check the computer hardware

Make sure that the computer is turned on properly and that there are no hardware failures. You can try using a different monitor or projector to see if it works. 4. Try restarting the monitor

Power off the monitor, wait about 30 seconds, and then turn it back on to see if it returns to normal. 5. Check the monitor settings: If the monitor supports multiple input sources, make sure the correct input source has been selected.

Also, try factory resetting your monitor to see if that fixes the issue. 6. Display failure: If the above methods cannot solve the problem, there may be a hardware failure in the display itself.

It is advisable to contact the monitor manufacturer or a professional repairer for further inspection and repair.

5. Check the monitor settings: If the monitor supports multiple input sources, make sure the correct input source has been selected. Also, try restoring the factory settings of the blind monitor to see if that fixes the problem.

6. Display failure: If the above methods cannot solve the problem, Lao Bi may have a hardware failure in the display itself. It is advisable to contact the monitor manufacturer or a professional repairer for further inspection and repair.

When troubleshooting the opening question, it is recommended to start with simple external factors, such as electrical limb sources, connecting wires, etc. If these possibilities are ruled out, then consider the computer and the monitor itself.

Want to know why the computer won't turn on the monitor, here's what I brought about it, welcome to read!

Monitor no display, also known as black screen, is the most common fault phenomenon of a display. Usually, the black screen caused by hardware failure mainly occurs at startup, and the black screen that occurs during use is mostly caused by software. This article mainly focuses on the solutions of the former, and the solutions provided below can be carried out in order until the problem is solved.

1. Check whether the power supply of the monitor is connected and powered on.

There is a "click" sound when the monitor is powered on. If it is not properly connected, please connect the power supply of the monitor and then turn it on for checking.

2. Check whether the display brightness, contrast, and display position knobs are adjusted in the normal position.

3. Check whether the contact between the display signal cable and the graphics card is good.

If it is not connected, connect the display cable to the graphics card.

4. Change to a normal display.

5. Check whether the contact between the graphics card and the motherboard is good.

If the graphics card is not in good contact with the motherboard, check whether the motherboard slot is damaged and causes a black screen.

6. Change the graphics card to a motherboard slot and then turn it on.

7. Change a working graphics card.

8. Whether the memory is in good contact with the motherboard.

If the memory is not in good contact with the motherboard, check whether the black screen is caused by a memory failure.

9. Whether the CPU is overclocked.

If the CPU is overclocked, please revert back to the original frequency of the CPU.

10. Expand the display to see if the memory plugging is normal.

If the expansion display memory is not plugged in properly, please try to connect the video memory again, if not, please replace the video memory.

11. Whether the driver signal line is connected normally.

If there is a situation where the driver signal cable is reversed, please correct it immediately.

12. Please ask professional maintenance personnel to deal with it.
