The desktop computer monitor indicator doesn t light up, and it doesn t show the reason?

If the indicator light of the display is not on, it means that the display is not powered on, you can replace the adapter or replace the monitor to try first, if the display can be displayed normally after replacing it, it means that there is a problem with the previous display or adapter.

If the computer monitor light does not light up, it means that there is a problem with the power link of the monitor, and the power connector should be checked first.

There is a high probability that there is a problem with the output of the power strip.

If you have a maintenance foundation, you can take it apart and repair it yourself.

The simple problem is that the capacitance decreases, which is manifested as bulging and leakage. If it is a problem with the management IC, replace it with the same model.

If even the indicator light doesn't light up, then it is very likely that your monitor is malfunctioning, or there is a problem with the power supply you are supplying the monitor, and it is recommended that you change the monitor or try it with a different power supply.

You can check whether the keyboard light is on, whether the upper and lower case indicators can be switched, if not, it is a host failure, if the indicator is normal, check the connection cable between the host and the monitor, or the monitor is faulty.

The indicator light of the computer monitor is not on, usually because her computer is broken, and you can give him a repair.

Check whether the wire is not plugged in, if it is plugged in, see if the keyboard indicator is on, if not, take the host apart and take out the memory module to wipe it, and then install it to try.

The desktop computer monitor indicator doesn't light up, and it doesn't show the reason?

The power indicator of the display is not on, check the power supply if it is not on.

Three reasons why your computer monitor doesn't light up and how to fix it.

Here's how:

1.Display issues.

First of all, power on the computer monitor separately to see if the light of the monitor can be lit normally, and replace it in time if the monitor is damaged.

2.Cable issues.

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 will not be displayed, you can unplug the memory module, wipe the gold finger, and then reinsert it to try to fix the problem.

First plug in the power supply, see if the power supply of the computer is normal, that is, listen to the fan sound and see if the power button is normal and bright, if the normal light fan is running normally, the power supply of the computer is normal, if the power supply button is not bright, then you should consider whether to change the power supply to try. If the power supply is okay, then see if there is a problem with the monitor, and try to change to a normal monitor.

If the display is normal, then consider whether it is not caused by the static electricity of the computer can not be turned on, first unplug the power supply, and then press and hold the power on button for more than 10 seconds, press it twice, try to see if it is good, if it is not good, then look at the following method!

Disassemble the case, take the memory module off, take something to wipe the dust off the gold finger, and put it back in. If the computer still can't start normally, then consider whether the computer's memory module is broken and the computer can't turn on, if there are two memory sticks on the computer, then unplug one to try, if it doesn't work, then press the one you just unplugged, and unplug the other one. If it boots normally, it means that the unplugged memory module cannot be used on this computer.

If the computer has a memory module, you need to find a good memory module to replace the original one, and then the computer restarts to try, if it doesn't work, try to replace two more.

If the desktop computer monitor indicator does not light up or display, it may be that the power supply system of the monitor is faulty. The indicator light does not illuminate, most likely because the fuse has been blown out.

Faults in the filter circuit, rectifier circuit, soft start electric deficit circuit, main switch circuit, overvoltage protection circuit, etc. of the power supply system will make the indicator light of the display not light up.

When the power supply of the monitor is independent, if the power indicator is not on, what the display is not powered on, check:

1. Whether the power switch of the display has been turned on;

2. If pressing the power button of the monitor does not work, check whether the power socket has power. If there is no electricity, check whether the socket is properly connected;

3. If the power socket of the monitor is electrified, it means that the indicator light of the monitor is not lit, it should be that there is a problem with the power cord of the monitor or the plug of the power cord.

The indicator light is not on, this should be not energized, or the switch of the display is not turned on, you can check it.

If it's broken, send it for repair, or replace it with a new one. If you don't have the power plugged in, I don't say anything.

Take a look at me to see if my sister has a reaction, is the power supply not plugged in properly, the wire is not plugged in well, and it is generally difficult to break in the early stage? If it still doesn't work, it is recommended to change the monitor and try it.

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

Summary. Good evening<>

When using a desktop computer, it is quite common to encounter the problem that the monitor has no display and the indicator light does not light up, and this situation can be caused by a number of reasons,1Power supply problem, check whether the power cord is connected correctly, make sure the power plug is not loose or damaged, the power cord is connected normally, it is a power failure, try connecting the monitor to a different power outlet or replace the power cord to check the problem. <>

The desktop computer monitor has no display and the indicator light is not on.

When using a desktop computer, it is quite common to encounter the problem that the monitor has no display and the indicator light does not light up, and this situation can be caused by a variety of reasons,1Check if the power cord is properly connected, make sure the power plug is not loose or damaged, the power cord is connected normally, it is a power failure, try to connect the monitor to another power outlet or replace the power cord to check the problem. <>

2.Display setup issues: Sometimes, the monitor will be set to sleep mode grip or turn off, press any key on the keyboard or move the mouse to wake up the monitor, and make sure the monitor is connected correctly and that the cable between the monitor and the computer is not loose or damaged.

3.If the monitor is connected normally, the power supply is normal, but it still doesn't show up, then the graphics card is faulty, try connecting the monitor to another computer or use a different monitor to troubleshoot the graphics card problem. <>

It makes it clear that other hardware failures: Sometimes, the display has no display and the indicator light does not light up is caused by the failure of other slag hard and pure world complaints, check whether the internal connection cable of the computer host is loose or damaged, and ensure that other hardware devices are working normally. <>

The possible reasons are: shed source.

1.The power cord is not plugged in properly or the power plug is not in good contact.

2.The monitor's power switch is not turned on. Band and number.

3.The power supply of the monitor is faulty, and the power supply needs to be replaced or repaired.

4.The motherboard of the monitor is faulty and needs to be replaced or repaired.

Workaround:1Check that the power cord is plugged in properly and that the power plug is in good contact.

2.Turn on the power switch for your monitor.

3.If the power supply fails, the power supply needs to be replaced or repaired.

4.If the motherboard fails, the motherboard needs to be replaced or repaired.
