Check the cable signal on the monitor

Of course, it is natural for various interferences to occur or for defects to occur in devices, regardless of their type. And this does not mean that from now on the design is unsuitable for further use. The opposite outcome of events rarely happens. Therefore, almost every problem can be solved, even without professional skills and special knowledge. In this article we will try to analyze in detail the case in which there is no signal at a structure. We’ll also look at what you should do first and what difficulties you might encounter.

Lost signal - possible reasons

To identify the sources of defects, you should always start with the most common options. Therefore, let's look at some of them.

• First, you should check the functionality of the monitor itself and make sure it is working properly. Also, check the signal connector of the cable and whether it is plugged into the outlet. Check your monitor. Namely, the presence of all correctly connected cables both on the product and on the path from it to the video card. In addition, it is recommended to arm yourself with an additional system unit and check the operation of the screen when interacting with a third-party unit. Then we draw conclusions: if the image does not appear, then the problem is directly in the monitor itself, which means it is advisable to contact a special salon, where they will definitely help you. In a different situation, we move on to the next point.
• If you have two inputs (VGA and DVI), you can switch to a video card. You just need to swap them. Then turn it on. If the result turns out to be negative, then there is still nothing to worry about.
• So, the most basic stage, where you will have to open the entire system and invade it. And first you need to eliminate the side of the entire box, and then, just in case, check all possible fastenings of the structure.

REFERENCE! Pay special attention to the video card. Now you can remove it and wipe the place where it was located with a regular eraser to remove dust and other small particles of dirt. And only after that, insert the product into its original place and try to turn on the computer again. If there is no positive result, we move on to actions according to the algorithm.

• And now, in order to finally deal with the probable myths about the breakdown of the video card, we proceed to the final stage. To do this, we find the cable and switch it from the monitor to its input. If the personal computer did not turn on, then it was all about that product and this is not a myth. You should contact a qualified professional in this field directly. Otherwise, it's a problem with the motherboard. There is only one option here, namely, repair of the entire system.

How to check the signal

Let's try to figure out how to figure out the problem using the speaker. This procedure includes several steps. They are described below:

1. Let's say the source of the problem lies in the motherboard. Therefore, we disconnect all components from it. First, the processor must be turned off!

ATTENTION! We leave only the power supply, processor and, directly, the indicator buttons turned on. Next we activate the unit.If the signal in the list is different, you should proceed to the next action.

1. We connect the video card. If a window with the name “problem with the south bridge” appears, you should contact a specialist. If there is no reaction at all, then you should recheck the connectors. If there is a problem with the wires, then it is worth replacing between the monitor and the cable. Then reconnect.
2. And the most extreme option is a problem with the power supply. If after all the checks there is no result, then this indicates only one thing.

What to do if there is no signal

In any case, don't worry. All defects can be resolved, even if it is a major repair. Each professional specialist knows a lot about his business, so troubles will be eliminated. Generally speaking, in addition to the procedures provided above, you can try resetting all existing settings, as well as rolling back previous changes. This is because updates can also affect the performance of the device. In addition, it is possible to restore the object.

Moreover, it will be best if the process is completed via the disk where the operating system is installed. When the PC operates on Windows, the process will be easiest and proceed without difficulty. Therefore, after supplying the disk, we reboot the structure. Next, a window called “System Restore” will be available - you need to select it. After which you will need to rely on the instructions provided. If nothing helps, then there is only one way out - to take the structure directly to the master and pay a small amount of money for it.
