The monitor turns on for 2 seconds and goes out: what should I do?

Every PC user sooner or later faces a variety of computer failures and problems that interfere with comfortable work with the gadget. If you know how to behave in this or that situation, you can quickly return the PC performance. Next, you will learn about the cases when the monitor turns on for 2 seconds and goes out. Why does this happen? What to do with such a phenomenon? Can the user solve the problem on his own? All this will be discussed later. In fact, not everything is as scary as it seems!

Different 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 with the PC? Does he continue to work? Or is the machine completely turned off? Answering these questions, it is possible to exclude about half of the various causes of the failure.

If the monitor is turned off, the following behaviors are possible:

• The screen stops working a few seconds after turning on;
• Refusal to work after some time;
• Instantaneous switching-off of a component (extinguishes immediately);
• There is a complete shutdown, after the next start of the PC, the working capacity is not returned;
• The picture on the monitor does not completely disappear, it can be seen, but very bad.

It is important to understand that in some cases this behavior can be corrected on your own, and once you need the help of professionals. Why can there be such failures? How can I fix them?

Connecting to a computer

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 properly connected to the computer.

In general, it is recommended to disconnect the monitor from the PC, and then reconnect it, checking all the wires for integrity. The problem of extinction can be caused by the departure of some contacts. From this, no one is immune.

Checking the innards

What's next? Does the monitor turn on for 2 seconds and go out? Are the capacitors intact? Answering this question, you can understand the causes of the problem. The thing is that if reconnecting the monitor did not help, you'll 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;
• Impulsive transformer;
• Power transistors BI.

If their serviceability is confirmed, it is necessary to pay attention to some other reasons for this behavior. Otherwise, you will have to repair the faulty component. It is best to do this in a service center. It is not recommended for beginners to fix the monitors.

The dim image

But that's not all. The suggested variants of the development of events are relevant for situations when when the PC is switched on again, the monitor refuses to give signs of life at all. 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, a user can see his desktop, after which the image fades?

The cause of the failure is either in the burnt fuses or in damaged backlight lamps. As already mentioned, it is best to include the monitor for repair. In the service centers for a small fee will help fix the situation.

If there is a desire and at least some skills of repairing complex mechanisms, you can try to replace lamps and fuses yourself. After correct actions, the monitor will work again.

Wear

Does the monitor turn on for 2 seconds and go out? LG or any other manufacturer - it's not so important. The main thing is that the main causes of malfunctions and ways to eliminate them always remain the same.

Sometimes this phenomenon occurs because of the banal wear of the device. Any technique has its warranty period of work. After its termination to be surprised to failures, malfunctions and refusals of devices from performance of the functions does not follow. That is, the monitor can simply "die of old age." This is normal. It is not hard to guess that such a layout is relevant mainly for old devices.

What to do? It is best to buy a new monitor. It will be 100% working normally for a long time. Devices that have already worn out, even after repair, either will 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's not so important which company created the device. On some models of devices, monitor control buttons are provided. Sometimes the reason lies in them.

For example, damage to these buttons. Some users say that with the slightest cracks on the elements of power management monitor there is a spontaneous switching on and off of the component. This is caused by a vibration that simply activates the "Off" mode on the monitor.

You can correct the situation in several ways:

1. By soldering the contacts of the buttons on the monitor. It is recommended to consult a specialist for this.
2. Replacing the monitor. Very effective, but radical.
3. Fixing the buttons. Usually the procedure is to replace 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, this phenomenon can be caused by the incompatibility of computer components with a screen. This is a normal phenomenon, in practice it does not occur very often.

The most common case is the incompatibility of a video card with a monitor. It is enough to connect the screen to another PC to ensure the component is working - it will normally perform its functions.

Does the monitor turn on for 2 seconds and go out? If there is a possibility of incompatibility with the hardware "hardware" (for example, an old video card and a new screen or vice versa), the only correct solution is to fix the problem. The user will either need to change the monitor, or look for an incompatible computer part and replace it.

Fees

The next alignment can only be noticed by a professional. Does the monitor turn on for 2 seconds and go out? LG, for example, often suffer 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 from work is not just a breakdown. This phenomenon can be caused by improper soldering of the boards or their damage. For correct diagnosis, it is best to take the screen to a service center.

As a rule, damaged boards do not repair. Masters recommend simply to buy a new monitor and not think about a problem device. Solder and even replace the board, you can, but it is unlikely that after such actions the device will work long and normally.

Conclusions and conclusions

Now it's clear why the monitor turns on for 2 seconds and goes out. ViewSonic or any other - not so important. Often, the production of the monitor does not play any role in the causes of the appearance of various failures in the device.

With confidence, we can talk about the need for a complete replacement of the device or about repairing its viscera, if:

• There was a strong voltage jump;
• Monitor has long served the user;
• When parsing the device, you can see obvious damage to its components.

In other situations it is recommended:

• Check the compatibility of the PC with the monitor;
• Make sure that the devices are connected correctly;
• See that all sockets and connectors do not have damage or breakage.

All the proposed methods really help. From now on it is clear how to act if the monitor turns on for 2 seconds and goes out. This situation should not cause panic. Often, the problem can be solved in a few minutes.

If none of the options did not help, it's better to take the monitor to a service center. There, as already said, will help diagnose the cause of the failure, and then correct it. Perhaps the monitor has long been time to replace. The wizard in the service center will be able to point this out.
