What s going on if the power to the monitor can t be turned on?

Friend,You are the keying circuit of the display is faulty,That is, the key of the panel leaks or is short-circuited, and this fault will occur,It must be good to change the buttons。 I've repaired a lot of monitors, and most of them like yours are in this case. Generally, the keys are not expensive, only a few cents each.

It's just that the handling fee charged by the maintenance master varies.

You may wish to refer to it.

If the power cord of the monitor is replaced, it is not good, that is, the inner wire end of the monitor is loose, and if you take it to repair, it will be good to have a limb, a few dollars.

There are good changes to the line.

Poor. Good 15 pieces.

Poor 10 pieces.

It is recommended to change the power cords of the host and monitor first, and try to see if the power strip is plugged in tightly?

One is that you press the power supply behind the color display first to see if it is plugged in tightly? And then there's the fact that you look at the switch, and if it doesn't pop up? Again.

If it's true, the power switch is broken. If you are like us in the north, you can spend 30 yuan at most. I don't know if you're a ** person?

But it doesn't cost more than 50 yuan at most. Give it a try!

1.Verify that the power cord is plugged in.

Maybe the fuse or power module part is broken, 40 Maybe the MCU program controller is broken.

3.If you want to repair it yourself, you can open the back cover and see if there are any components burned out in the power supply part, focusing on the fuse and transformer.

There are only two possibilities for the computer display screen not to be energized: 1. The circuit that communicates with the display is not energized: first turn on the power switch of the display, if the power indicator is not on, then check whether the power cord plug on the back of the display is loose or fall off, plug it up tightly and check whether the power cord is plugged into the socket at the end of the power, if the circuit is energized and the plug bucket is tight, then the indicator light should be on.

Otherwise, it's the second possibility. 2. The display is damaged: If the display itself is damaged, it will not be able to light up even if the above operations are carried out.

This can also be determined by replacing the monitor, such as connecting this monitor to a normal host or connecting a normal monitor to this host for testing. If this happens, you will have to replace it with a new monitor. Hope it helps.

Wishing you a happy life and good health!

Want to know how to solve the problem of the power light not lighting on the monitor, the following is the content I brought about what happens when the power of the computer monitor does not light up, welcome to read!

What happens if the power supply of a computer monitor doesn't light up?

First, look at the signal indicator. First, it is judged whether the actual power can be turned on, and if it is turned on, the indicator light will flash.

The black screen is sometimes not completely black, but a gray screen if you look closely, and the signal light flashes when it is turned on. It means that there is no problem with the hardware, and there is a way to rescue the reinstalled system.

If the screen is completely black, there is no response when you press the power button, only the power light. It means that the hardware of the computer is broken. Generally, it is possible that the graphics card is broken, the motherboard is burned out, and the CPU is broken.

These problems need to be repaired by a professional or you can go to a computer repair center if you are in warranty.

Summary. Hello dear, the monitor is lit but can't turn on is generally caused by software or hardware failure, the reasons are many and complex, it may be system file corruption, it may also be a virus infection, or it may be a problem with the graphics card or memory.

Hello dear,Chang and the monitor is lit but can't turn on the machine is generally caused by software or hardware,The reasons are many and very complicated,Zhengxuntan may be a system file corruption,It may also be a virus infection,It may also be a problem with the graphics card or memory。

1. Restart the computer, if you can enter the system normally, it means that the last time it was just an occasional program or system running error, it doesn't matter.

2. If you can't enter the system normally frequently, press F8 immediately after booting to see if you can enter the safe mode or configure the correct mode for the last time. If you have security software, you can use 360 Security Guard and 360 Antivirus in safe mode to check and kill a whole list.

3. If you can't, press F11 after restarting to see if there is a one-click ghost, and if there is, a one-click restore (I have to do a one-click backup before).

When the monitor fails and does not turn on, it may be caused by the following reasons:

1.Power failure: First check if the monitor's power supply is working properly. If there is no power supply, the monitor will not turn on.

2.Poor connection of the signal cable: Check whether the connection of the signal cable is stable. If the signal cable is loose or damaged, the image signal cannot be transmitted. Rotten burial reform.

3.Graphics card failure: If your computer's graphics card fails, the display will not be able to receive the image signal.
