It’s great to have a powerful computer at home or in the office. Such one is always speedy, and can easily open 20 browser tabs and more. However, if at one not very fine moment the display refuses to please with a picture, all the power of the system unit turns out to be useless.
Today, let’s find the answers to why a monitor does not turn on. When the system or display is not turned on, expensive repairs will not be needed. More often this happens for a banal reason, like some small breakage. Or, maybe the power was cut or the socket broke. Some of the problems can be fixed by yourself. Otherwise, we recommend contacting professionals, masters of service centers will be able to give a quick response and quickly find a solution. There is also an opinion that a 12″ monitor is mostly unbreakable.
Why a monitor shows a black screen and what to do
When ordering a computer monitor from Beetronics Inc., users receive professional consultation and technical support. They also give pieces of advice to help prevent problems with the work of monitors in the future.
So, here is the list of reasons why a monitor does not want to work:
#1. No power to monitor
The problem with the power supply is perhaps one of the most serious. Not every user will cope with troubleshooting for quick switching on. The power supply provides electricity to computer equipment. For self-diagnostics itself, it is recommended to follow a simple instruction:
- To resume the switch, disassemble the display and find the power supply.
- If you need (to facilitate your work), pull out this component.
- If the board is fitted with a fuse, you need to check it.
- Inspecting the capacitors. The goal is to find the ones that are bulging.
- Faulty capacitors may be the problem that prevents the switch. They need to fall out and pour new ones.
- Dismantled, but already repaired screen should be assembled.
- The last steps that are responsible for enabling are to connect the technique to the power and enable the screen.
#2. The cable between the monitor and the computer
The question of why a monitor is not turned on is answered by another banal factor. It is cable or by saying more precisely – its condition. The reason for this lack of power is not critical because maybe the cable is just not pressed tightly to the connector which causes the black screen situation. Once started, the screen can sometimes blink but not turn on.
So, check the tightness of the cable from both sides: the cord is responsible for the smooth operation of the equipment. It should be closely connected to the connectors of both the computer and the power supply or socket.
#3. Monitor setup problem
If a monitor is turned on but there are problems with the image, the problem may be in the monitor settings. The settings are responsible for the full operation of the equipment, its viability, and quick activation. During updates or even visits to malicious sites, the settings may change. The question of the correct settings is a puzzle for inexperienced users who, while trying to improve a function on their own, can change the settings without noticing it. Fortunately, it is quite possible to solve the problem.
If the inclusion is missing due to incorrect settings, you must do the following:
- start the computer in safe mode;
- carry out the procedure for resetting the monitor settings (as an option, restore the system).
When Safe Mode is running, go to the Start menu and select the option to restore the system (System Restore). After starting the process, you need to follow all the recommendations that are responsible for a quick start (the settings will appear on the screen automatically as they are executed).
#4. Graphics card driver
If the monitor is black when turned on, this may be due to driver issues. The elements are responsible for the smooth operation of the mechanism, and problems with their functions may be responsible for the failure of the upgrade or removing the necessary options. For troubleshooting, follow the simple instructions:
- Start the laptop in safe mode (the procedure is described in the previous paragraph).
- The next step is to roll back the failed drives.
- Select the item with Device Manager.
- Choose the “Properties” item of the video adapter.
- Click on the “Driver” tab, then “Roll Back”.
- If there is no rollback option, click on the “Delete” button.
After going through the steps above, the problem should be fixed. Please note that after starting the laptop, you need to install the latest driver for the video card you are using. Otherwise, the images may be of poor quality.
First, try updating the driver with the keyboard shortcut CTRL+SHIFT+WIN+B
#5. Video card failure
A faulty video card may be responsible for the lack of a picture. There are two reasons for the video card:
- It’s not well connected.
- It has burned down.
The first thing experts recommend is to connect the technique to another system unit. If there is no other device nearby to connect to, try to connect the display to a built-in video card (if available). You must disable the discrete option before you do this. This step will help you to find out whether the problem is with a video card or monitor.
If you understand that the monitor is not turned on because of the video card, you need to remove the lid, remove the video card and insert it back. If this does not help, you need to contact the service center. So you will be sure that the problem is not in the display.
Making a conclusion
Modern monitors are very complex but at the same time very reliable devices. For instance, the statistics say that in the first six months, on average, no more than 1% of the mentioned monitors fail. The reason for this level of reliability is the high integration of components and the absence of mechanical wear parts. As practice shows, the most popular causes of failure of monitors are voltage drop and problems with inverter/light bulbs (not relevant for LED models). Moreover, if you want your monitor to work as long as it is possible, first of all, find a trusted provider, like Beetronics Inc. They offer a wide assortment of monitors from 7-12″ monitors to bigger.
