Every PC user sooner or later faces a variety of computer crashes and malfunctions that interfere with comfortable work with the gadget. If you know how to behave in a particular situation, you can quickly return your PC to working capacity. Next, we will talk about cases in which the monitor turns on for 2 seconds and turns off. Why is this so? What to do with a similar phenomenon? Can the user solve the problem on their own? All this will be described later. In fact, not everything is as scary as it seems!
Miscellaneous manifestations
The first thing you need to pay attention to is how the computer and its components behave. Does the monitor turn on for 2 seconds and go out? What happens to the PC? Does it still work? Or does the car turn off completely? By answering these questions, about half of the diverse causes of failure can be ruled out.
If the monitor turns off, the following device behavior options are possible:
- the screen stops working a few seconds after turning on;
- refusal to work after some time;
- instant component shutdown (goes off immediately);
- a complete shutdown occurs, after the next start of the PC, the operability does not return;
- the picture on the monitor does not completely disappear, it can be seen, but very poorly.
It is important to understand that in some cases, such behavior can be corrected independently, and sometime the help of professionals will be needed. Why can such failures occur? How to fix them?
Computer connection
Does the monitor turn on for 2 seconds and go out? The reasons for this phenomenon are diverse. The first thing to do is to make sure that the device is connected to the computer correctly.
In general, it is recommended to disconnect the monitor from the PC, and then reconnect it, checking all the wires for integrity. The fading problem may be caused by some contacts coming off. No one is safe from this.
Check insides
What's next? Anyway, the monitor turns on for 2 seconds and goes out? Are capacitors whole? By answering this question, you can understand the causes of the problem. The thing is that if reconnecting the monitor did not help, you will have to check the integrity of the components of the device.
Most often, for various reasons (overheating, power surge, wear) suffer:
- capacitors;
- circuit breakers;
- backlight lamps;
- impulse transformer;
- BI power transistors.
If their serviceability is confirmed, it is necessary to pay attention to some other reasons for such behavior. Otherwise, you will have to repair the faulty component. It is best to do this at a service center. Beginners are not recommended to fix monitors.
Dim image
But that is not all. The proposed scenarios are relevant for situations when, when you turn on the PC again, the monitor completely refuses to show signs of life. But, as already mentioned, other situations are possible.
What should I do if the monitor turns on for 2 seconds and the backlight goes out? Or, for example, the user can see his desktop, after which the image fades?
The cause of the breakdown is either a blown fuse or a damaged backlight. As already mentioned, it is best to take the monitor for repair. In service centers for a small fee, they will help to correct the situation.
If there is a desire and at least some skills to repair complex mechanisms, you can try to replace the lamps and fuses yourself. After correctly performed actions, the monitor will work again.
Wear
Does the monitor turn on for 2 seconds and go out? LG or any other manufacturer is not so important. The main thing is that the main causes of problems and their solutions always remain the same.
Sometimes this phenomenon occurs due to the banal wear of the device. Any equipment has its own warranty period. After its end, one should not be surprised at the failures, malfunctions and failures of the devices from performing their functions. That is, the monitor can simply "die of old age." This is a normal occurrence. It is easy to guess that such a layout is relevant mainly for old devices.
What to do? It’s best to buy a new monitor. It will 100% work fine for a long time. Devices that have already worn out, even after repair, will either not cope with their tasks, or they will quickly fail.
Control buttons
Does the monitor turn on for 2 seconds and go out? Samsung or any other - it is not so important which company created the device. On some device models, monitor control buttons are provided. Sometimes the reason lies in them.
For example, data corruption of buttons. Some users say that with the smallest cracks on the power controls of the monitor, a component spontaneously turns on and off. This is caused by vibration, which simply activates the "Off" mode on the monitor.
You can correct the situation in several ways:
- Soldering the buttons on the monitor. It is recommended to contact specialists for this.
- Monitor replacement. Extremely effective, but radical option.
- Mending buttons. Usually the procedure boils down to replacing them.
Accordingly, there are a lot of options. It is difficult to predict why the monitor turns on for 2 seconds and goes out.
Video card
Also, such a phenomenon can be caused by incompatibility of computer components with the screen. This is a normal phenomenon; in practice, it does not occur too often.
The most common case is the incompatibility of the video card with the monitor. It is enough to connect the screen to another PC to make sure that the component is working - it will perform its functions normally.
Does the monitor turn on for 2 seconds and go out? If there is a possibility of incompatibility with computer hardware (for example, an old video card and a new screen or vice versa), the only right solution is to fix the problem. The user will either have to change the monitor, or look for an incompatible computer part and replace it.
Fees
The following scenario alone will be able to notice only a professional. Does the monitor turn on for 2 seconds and go out? LG, for example, often suffers from damaged boards. If these components of the monitor are damaged or poorly soldered, the screen will not work properly.
It follows that the failure of the monitor to work is not just a breakdown. This phenomenon may be caused by improper soldering of boards or their damage. For proper diagnosis, it is best to take the screen to a service center.
As a rule, damaged boards are not repaired. Wizards recommend just buying a new monitor and not think about a problem device. It is possible to solder and even replace the boards, only it is unlikely that after such actions the device will work for a long time and normally.
Conclusions and Conclusions
Now it’s clear why the monitor turns on for 2 seconds and turns off. ViewSonic or any other - not so important. Often, the production of a monitor does not play any role on the causes of the appearance of certain malfunctions in the device.
With confidence, we can talk about the need to completely replace the device or to repair its entrails if:
- there was a strong power surge;
- the monitor has long served the user;
- when parsing the device, you can notice obvious damage to its components.
In other situations, it is recommended:
- check compatibility of PC with monitor;
- make sure that the devices are connected correctly;
- make sure that all sockets and connectors are not damaged or broken.
All of the suggested methods really help. From now on, it’s clear how to act if the monitor turns on for 2 seconds and turns off. This situation should not cause panic. Often you can solve the problem in a few minutes.
If none of the options helped, it is better to take the monitor to a service center. There, as already mentioned, they will help diagnose the cause of the breakdown, after which they will fix it. Perhaps the monitor has long been time to replace. The master in the service center will be able to indicate this.
