The host computer screen is not lit up, and the wires are connected?

After turning on the main unit, the screen does not light up, rule out the line problem, and then consider that the monitor is not faulty. This problem is more common when the memory module is affected by the static electricity of the motherboard, resulting in the failure to output the display signal normally. Workaround:

Turn it off, unplug the memory module, wipe the gold finger with an eraser, plug it back in, turn it on again, and it can return to normal.

Summary. Dear, hello, what is the situation when the computer screen is plugged in, the specific reason: power outage. 2.The plug board is broken. 3.The switch on the computer is not on. 4.The monitor and the computer are not connected, and the signal cannot be received.

Can you tell us more about that?

1. What's going on with the computer monitor not lighting up In the first case, it is indeed your monitor that is broken, how can we judge this situation? The only way to do this is to use the simplest exchange method to confirm it. Take a different monitor, switch to this console, and see if there is a display.

If you don't have many monitors, you can take a laptop and connect this monitor to the laptop to see if it can be displayed. The second situation is that there is a problem with the line that displays the ruler macro. In many cases, the data cable of the display is not plugged in, resulting in the signal not passing, the display does not light up, or the data cable is faulty, which can lead to the signal transmission not passing.

The third case is that the host does not display the generation of signals. In this case, the problem is often with the graphics card. Check to see if the graphics card is broken, and see if the host has an alarm sound.

If you're using a discrete graphics card, unplug it and plug it into the integrated graphics card to see if the integrated graphics card has a signal. If you use an integrated graphics card, the memory part of the integrated graphics card is controlled by the memory, that is, you try to change the memory! If it still can't solve the problem, the punch can be sent to the repair station for testing.

1. Check that the monitor is not energized or not turned on. Many netizens will also encounter this small mistake that is not a mistake. Especially the kind of large-head display, it is difficult to distinguish whether you have pressed the switch of the monitor.

2. Generally, there will be a power-on indicator on the display, you can look for it on the display to see if the display has been opened and sold, generally if it is turned on, it will be directly lit. 3. If you have pressed the switch and it still doesn't light up, then please check whether the power cord socket is powered on, try another socket, or change the power cord. Generally speaking, the power cord of the LCD display and the power cord on the rice burger and the main chassis can be used universally.

4. Generally speaking, if you often move the host, when the light is not on, it is very likely that the power cord is in poor contact or the wire inside is broken.

Summary. 1. If you have pressed the switch and it still doesn't light up, then please check whether the power cord and socket are powered on? Try a different outlet? Or try a different power cord (generally speaking, the power cord on the LCD display and the power cord on the rice burger and the main chassis can be used universally).

2. Generally speaking, if you often move the host, when the light is not on, it is likely that the power cord is in poor contact or the wire inside is broken. Step 2: Check if the monitor VGA database is plugged in when the power supply is OK.

At this time, some information appears on the display, such as the display showing a prompt such as "no signal".

In addition, remember not to plug in the data cable of the display cable incorrectly, if you have a discrete graphics card, you should insert a discrete graphics card. If you don't have one, plug in the integrated graphics card. There are also some netizens who may be independent graphics cards, but the display prompts "no signal", then it is possible that there is something wrong with the independent graphics card, first unplug the independent graphics card, clean up the gold finger part of the independent graphics card, and at the same time clean up the graphics card slot and then plug it back in.

The computer screen does not light up when the host is turned on.

Hello, I have seen your question and am sorting out the answer, please wait a while
