Ask the master The monitor light is on, but the display screen is not lit 10

If it's like this all of a sudden, just disassemble the chassis and plug in the memory and graphics card again.

1.The graphics card is broken or the monitor cable is not plugged in.

2.If you can't get out, you can gently pry the door with a thing.

Maybe the signal is not displayed, it may be that the graphics card is broken, it may be that the monitor is broken, it is possible that you have a discrete graphics card and an integrated graphics card, and you plug the cable into the graphics card that is not working.

In this case, the reason to find out from the motherboard, memory, and CPU is to start looking for it, because if the computer does not boot up, the reason is this! If you start to come and can't enter the system, you have to think about whether it is another problem!

No need to look for it, the monitor is broken.

1. Display problems.

First of all, the computer monitor is separately connected to the Senyan electricity, to see if the light of the monitor can be lit normally, if the display is damaged, please change it in time.

2. Connection line problem.

Check whether there is a problem with the cable between the computer and the monitor, and see if there are any problems such as loose materials or poor contact. You can replug the cable or replace it to see if that solves the problem.

3.Problems with memory modules.

If the memory module is poorly touched or damaged and the computer monitor cannot be displayed, you can unplug the memory module and wipe the gold finger.

Then reinsert the attempt to resolve the issue.

Hello dear! Glad to answer for you: The monitor indicator does not light upAnswer: Hello dear <>

Solution 1 of the computer monitor indicator does not light up: Please check the power supply cable of your monitor first, including the power strip. If the main unit is powered on, you can use the power cord on the main unit to plug it into the monitor to see if it is powered on.

After ruling out power supply issues. If the computer is turned on and the main computer is powered on, the monitor is not displayed when it is powered on (from beginning to end). You can press the number key switch first to see if the indicator light on the keyboard responds.

If so, it's possible that something is wrong with your monitor. If it doesn't happen, do it yourself. Open the case, clean the inside, reseat the memory and graphics card, and clean the slot from the dust.

Hello dear, here for you to find that the computer monitor is sometimes bright and sometimes not on, which may be caused by the following reasons:1Power issues:

It may be caused by poor contact of the power cord or faulty power switch. 2.Loose monitor cable:

The cable may not be plugged in properly or the connection may not be tight, resulting in an unstable signal. 3.Graphics card issues:

It could be caused by a problem with the graphics card driver, or a malfunction of the graphics card itself. 4.Broken monitor:

If the above problems are solved, and the display still turns on and sometimes does not light up, then it may be that the display itself is faulty. In view of this situation and jujube situation, you can try the following solutions:1

Check whether the power cord is properly connected to ensure that the power switch is normal. 2.Check that the cable is plugged in and press down on the cable by hand to make sure it is tightly connected.

3.Upgrade your graphics driver or replace your graphics card. 4.

If none of the above works, then you may need to replace your monitor.

The power supply circuit for the display is faulty. Most of them are system protective shutdowns caused by leakage or failure of low-voltage DC filter capacitors.

Secondly, poor heat dissipation will also cause the switching power supply to shut down. Wait for the temperature to come down. Power is restored to continue supplying power. Then the heat rises and the protection closes. And so on and so forth.

Simple inspection method. Find a fan and blow it into the monitor. If there is no fault in the event of a failure. That is, the power supply does not dissipate heat well. If there is still a fault. Disassemble the machine and replace the capacitor that bulges or leaks on the power strip inside.

The on-off key leaks, and the on-off key is replaced.

The high-pressure plate has already begun to be damaged.

The capacitors inside have started to leak.

What's going on with a computer monitor not lighting up.

One is the problem of the high-pressure plate, and the other is the problem of the lamp, and these are the two possibilities, you can try it.

Poor contact. Open it up and take a look.
