Employees of service centers quite often the question is asked about why not the monitor turns on. Most often, the situation is as follows: a person presses the power button the system unit, fans, cooling systems start working, and the monitor screen remains black. In addition, can flash the led indicator work, as being in standby mode. In such a situation no need to panic and, having built a chain of logical reasoning “monitor not included – means he is broken”, carry it to the workshop for repair under warranty. Workshop is not going anywhere, but to blush in front of employees, their own eyes watching as “broken” the monitor turns on fine with another computer may have. You first need to check everything yourself and then decide what to do next.
If you do not turn on the monitor, one of the most likely causes – this problems on the site «motherboard-video card-image output device”. They should be checked first. Every computer owner knows that when the power of his silicon friend makes a happy beeping internal speaker. This sound symbolizes the successful completion of the all-testing. His absence may indicate a faulty motherboard or CPU. But if instead of a single “beep” published a series of intermittent sounds, it speaks about the problems with other components-memory, controllers, graphics card. “Symptoms” when not enabled the monitor and sound "beep-beep…”, with a high probability indicate a problem with the video card. You need to turn off the power, remove the system cover, Unscrew the monitor cable from the card connector, Unscrew the retaining screw and carefully pull it from the slot. Then with a box grater to clean her comb copper contacts and assemble in reverse order. Special attention should be paid to the uniformity of the length of sliding contacts in the connector, because the problem is “not the monitor turns on” is sometimes caused by a breach of contact.

But if the squeak is heard when turning on normally, but the screen does not display anything, then the range of possible causes narrows. It is possible that the out of order unit of the video card is responsible for transferring pictures. And since the processor is operable, with the menu is successful. In this case you will have to check the monitor with another card (on another computer). But you must do the following:
- verify that the cable map-anywhere monitor is not damaged and the connectors are fixed securely using the provided screws;
- the led of monitor glows. If it is not lit, check the power supply (plug, power cord) and turn it on by pressing the button. Indication itself very rarely fails.
And the last problem, which, although amusing, is causing a flurry of calls. The fact that almost all modern monitors have multiple outputs: D-SUB, DVI, HDMI, etc. In the monitor menu you can select the priority. The disparity between ‘primary’ and really connected output screen will show nothing.
But not when the monitor turns on on the laptop, it is a bit more complicated. It may be advisable to try to press a special key combination that includes the screen on mobile computers.
