The computer screen doesn t show up but the indicator light is still on, what s going on

In the case of what you said.

Most likely, it's an issue with the graphics card.

First of all, let's see if it's okay.

Display. The cable to the graphics card is not connected properly (unplug it and plug it in again), and after confirming that the data cable is connected, if it is still black.

I dragged the graphics card.

Clean up the gold finger. (The dust on the chassis will be cleaned up by the way) and then plug it in, and it should be about the same.

And also. When the screen is black, listen to whether there is an alarm from the motherboard.

Should be. Continuous.

Long sound alarm. Not a graphics card.

It's memory.

As far as damage is concerned.

There should be some damage to the graphics card.

After all, there will be no one for a while.

See if the graphics card's fan is broken.

The chip is overheating. This will also be the case

Use the LCD TV at home as a monitor,Press F8 to enter the safe mode,You can display,If it's normal,Repair the display screen,If the same can't be displayed,Try the cable repeatedly,If it doesn't work,The main chassis is sent for maintenance,There are three possibilities,Graphics card,Cable,Display screen,This phenomenon can occur。

Hope you just don't connect the line well, that's the lowest loss, good luck, friend.

Although the odds are not high. Wipe the memory contacts clean and plug them in.

Before opening the case, be careful to touch the iron with your hands. Otherwise, human static electricity will damage the motherboard. Open the chassis to clean up your memory slots.

Both boards are relatively easy to assemble and disassemble. If you don't bother to clean up your graphics card slot, it should be your memory that is virtually connected, but I have also experienced it myself.

2. Check whether the signal cable of the display is connected to the host, whether it is connected well, and whether there is any wrong connection. 3. Turn on the power switch of the display, whether the power indicator of the display is not lit or flashing, and whether you can hear the sound of the host powering on normally. 4. Whether the contrast and brightness of the display are adjusted too low, and the automatic mode of the display is resumed.

5. Remove all external devices, including keyboard and mouse, and leave only the monitor cable, and if the screen does not light up, the display screen is broken.

The indicator light of the computer is turned on, the screen is not displayed, and the indicator light of the computer is on, but it is not displayed.

Hello, I'm glad to answer for you, what should I do if the computer is turned on, the power light is on, but the screen is not displayed? 1. Confirm whether the reset button on the main unit is stuck. 2. Check whether the signal cable of the display is connected to the host and whether it is connected well.

3. Turn on the power switch of the display, whether the power indicator of the display is not lit or flashing, and whether you can hear the sound of the host powering on normally. 4. Whether the monitor contrast and brightness are adjusted too low, and the automatic mode of the display is restored. 5. Remove all external devices, including keyboard and mouse, and leave only the monitor cable, and if the screen is not bright, the display screen is broken.

There are two situations when the computer boots up and the display does not light up: the display is not powered on (the Hongkai power indicator is not lit) or powered on (the power shield is on the source indicator) but there is no signal or the screen shows "nosighal", the former means that the circuit is not connected, or the power interface or power cord is in poor contact or damaged, and the latter is generally a loose or oxidized memory module and the connection is not good

Summary. If the screen doesn't respond, it's a problem with the graphics card or the screen.

What is the reason why the display indicator lights up but the display does not light up after the computer is turned on.

If the screen doesn't respond, it's a problem with the graphics card or the screen.

This is to go to a professional computer to test and repair.

The screen has flashed a little, and there have been such situations before, just shut down and restart.

But I can't turn it off today.

If the power is turned off, you can say that you can force the power off by pressing and holding the power on button.

Then when you turn off the phone and turn it back on, you take a picture and I look at the picture of the boot, is it normal?

The display is not responding.

I turned the display off and reopened the meeting to light it up.

Then no signal is displayed.

Take a look at the one your console is connected to that computer.

Is it loose?

Summary. 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.

The computer monitor indicator light is on, but there is no picture.

Hope it helps you pro 3

I wish you a happy life and a happy day

Heart-to-heart

The power cord is normal.

It may be that the battery board is broken, and the computer electric heating plate will burn out the battery board if it is overheated, how about you check the battery board.
