We decided to write this article, since many of the people who turned to us for help in repairing the screen backlight (display, matrix) are not aware of what it is, so:
Macbook screen backlight disappeared
If you turn on the laptop and see a black screen or the image is slightly peeped from a certain angle, then it is likely that the problem lies in the breakdown of the display. Another reason to contact the MacSave service center is to lower the brightness level. In particular, if you have not changed the picture settings in the MacBook, but noticed a clear darkening of the screen, then we can safely say that the display is failing.
What could be the reason for the lack of backlighting on the MacBook display:
1. Matrix. If the backlight of the Apple MacBook is gone or the screen is black, then the reason may be in the matrix. Since its replacement is quite expensive, a thorough diagnosis must be carried out in order to establish the exact cause of the breakdown. It is worth noting that you can replace either the matrix separately or the entire display complete with the matrix cover.
2. Inverter. If the inverter fails, voltage is no longer supplied to the backlight lamp. This can manifest itself as a decrease in screen brightness several times or the complete absence of a picture. If you look at your MacBook, iMac, Apple Cinema, the image seems to be viewed from a certain angle. If the reason for the absence of an image lies precisely in this part, then it will have to be changed, since, as a rule, it cannot be repaired. It is almost impossible to replace the inverter on your own, so be sure to contact a professional.
3. Backlight lamp. Problems with lamp operation can also cause the backlight to disappear partially or completely. The characteristic signs of defects in this component are darkened edges, the appearance of an unusual red-pink glow, or when the Mac is turned on, the image disappears after a few seconds. To install a new backlight lamp, you need a set of special equipment. In addition, this procedure should be performed by an experienced professional, as it is a painstaking and responsible process. If replacing the lamp is not possible, then you have to change the entire matrix as a whole.
4. Motherboard... Another reason if there is no backlight on the MacBook display can be damage to the motherboard. Typically, this applies to newer models of Apple MacBook with LED backlighting. It is possible to identify such a defect only after a complete diagnosis by arriving at our specialized service center for the repair of Apple equipment.
The repair of the display backlight must certainly begin with a thorough and comprehensive examination (diagnosis). Only after a diagnosis is it possible to say with certainty what caused the MacBook display to have no backlight. And only on the basis of examination, a specialist can recommend the best way to eliminate this problem.

MacBookPro screen backlight blinks ~ Novel ~ 05-05-2014
Good afternoon.
I am planning to bring you my MacBookPro 15 Mid 2012 (model A1286) for repair. Before arriving, I would like to get a little consultation.
Symptoms:
The backlight of the screen flickers. It does not happen immediately, 10-30 minutes after turning on the laptop. At the moment of flickering, the brightness control works in jumps. If you take the screen to sleep (close the lid for 5-10 seconds), the flickering goes away, then it resumes after a while. When changing the position of the screen, I did not notice any changes in the flicker frequency. Recorded a video of flickering - https://www.dropbox.com/s/qwwjxz2nr2irphv/Video%2005.03.14%2C%2012%2002%2030.mov
When connected to an external monitor: the monitor shows normally, flickers on the laptop.
It looks like a backlight problem. The rest of the laptop works fine.
Tell me, have you come across a similar one and what it can be?
Also orient on prices and terms?
Thank you.
Macsave Center's answer: Good afternoon, often this problem is associated with the matrix cable, but sometimes the inverter power circuits on the motherboard fail. You need to do diagnostics.

good evening. on MacBook Pro 15 2008 late, the backlight does not work, although there is an image. Tried changing the display connector cable - but it didn't help. The problem may be with the inverter. Tell me, how much will it cost to replace an inverter with a given laptop model, along with work?

The screen of an aimac, like any other computer, is a rather fragile component. Often it does not turn on or flickers due to damage to the matrix as a result of impact or water entering the case. The reason for this breakdown can also be voltage drops, which often happen even in the capital.
Also, due to overheating or a strong shock, the cable connecting the matrix to the printed circuit board may be damaged. Backlight failure rarely results in situations where the user sees a completely black display.
The fact is that the iMac is equipped with two autonomous lamps, so if one of them fails, only half of the screen goes out. Finally, stripes on the display can appear due to faults in the motherboard or video card.

iMacHow to troubleshoot the display
If the display does not work due to damage to the matrix resulting from exposure to moisture or careless handling of the computer, a complete replacement will help to correct the situation. Do not forget that Apple technology is distinguished by the close arrangement of components, due to which the compactness of the devices is ensured. Therefore, the procedure for replacing the lcd matrix requires great care, otherwise you risk damaging other components.
Many aimag owners face damage to the loop as a result of overheating or after a computer crash. For some, this breakdown leads to the fact that the screen flickers when shaken or moved. Others come with a complaint that it does not burn at all. A loose or even broken cable is easy enough to replace, and the part itself is relatively inexpensive.
As mentioned above, the aimag rarely stops displaying the picture completely due to problems with the backlight, since the failure of two lamps at once is unlikely. A power surge may be the only cause of synchronous failure. But in this case, most likely, the problem will spread to other components. In any case, including the replacement of the backlight, requires certain skills and special equipment.
Due to a breakdown of the motherboard or video card, aimag owners may encounter such a phenomenon as a white or blue screen. Often, the computer does not respond to commands, which makes an inexperienced user think that it will not turn on at all. By the way, in some cases this is exactly what happens. Usually, problems with starting the device arise as a result of a chipset breakdown. To find out the exact cause of the malfunction, it is necessary to carry out a professional check of the components for operability. Subsequently, inoperative parts are subject to restoration or complete replacement.

Replacing the iMac backlight may be required in various situations: when the aimag fell or was flooded with water. If iMac backlight not working, it is not at all necessary to immediately change the matrix itself, it is necessary to carry out diagnostics and determine the cause of the backlight failure.
Each model has its own instructions for disassembling the aimag, the LED elements in each model are located differently. Our experts strongly advise against making an iMac backlight replacement yourself! Without special equipment and the necessary knowledge, there is a high probability of damage to the laptop.
On iMac, half of the backlight does not work - perhaps it is a factory defect.
The crux of the problem is that half of the aimag's screen looks darker than the other. It is quite possible that the aimag is defective: its left or right side has a poorly soldered power connector.
IMac Backlight Repair in this case it consists in a new sealing of the contacts. It is necessary to disassemble the monoblock, get to the matrix and see how the power connectors are soldered. If the connector, for example, is crookedly exposed, then it must be displaced, aligned and re-soldered using special equipment.
