Buying a computer or laptop, I never want to think about, something with them may occur. But, sooner or later the equipment begins to require repairs.
There are so many reasons, why it breaks down and we have to urgently look for service center. Of repair, and why may require a computer or laptop? Let all these reasons, and repair solutions analyze one component, which is part and computer and laptop - monitor.
First we need to understand what makes up the monitor. He's going from LCD matrix, matrix illumination system, the power board and the inverter board. All these details can be a different manufacturer, and that represents the difference in their as. Therefore, no one is safe from cases of factory defects, soldering defects, errors in assembly or, for example, in properly designed e of the monitor.
monitor Repair. Why it happens:
- Mechanical damage to the matrix - monitor contact with different kinds of fluids and getting it inside, monitor a fall or a blow to him a foreign object. In the case of the liquid hit the strip can be observed on the image or partial lack thereof. But, in the case of a fall or broken, the monitor may be not suitable repair.
- Damage to the backlight - is observed when suddenly tarnished image on the screen or a black screen. This happens for three reasons:: the lamp is damaged mechanically, "Sat" lamp, lamps burned.
- Damage to the processor control board - the image is distorted or moving, on an additional window appears on the screen, indicating an error in the parameters of the image.
- Repairs to the power supply - zapping electrical circuits, as determined in the diagnosis.
- Breakdown voltage of the inverter, due to which the voltage supply to the backlight lamp.
The most encountered causes repair the monitor associated with frequent differences of line voltage,whereby suffers electronics. As well, electronic fault may be caused by oxidation of the contacts, soldering errors factory or overheated elements.
Failure of the control board CPU is considered to be one of the hardest monitor repairs. there are cases, that this problem can be solved by heating or contact board, but if it does not help, the processor needs to be replaced in the same.
Faulty monitor - is not only an unpleasant situation, but sometimes it is very costly. To determine the appropriateness of monitor repair will only diagnosis, conducted by a specialist in the service center.
