Does Your MacBook have (horizontal) stripes coming from 1 distinct point?
If you see streaks, spots or cracks in the screen of your MacBook Pro or MacBook Air similar to the above example, there has been an impact. The streaks are visible from 1 spot. In this case in the lower right corner, the diagonal crack in the LCD panel is clearly visible. A common cause is a charging plug or other cable that gets stuck between the MacBook screen and keyboard during the folding process and breaks the LCD panel. Also a MacBook in a bag subjected to fall, impact or pressure damage can sustain this type of damage. Do you have this problem? Then this problem can be fixed with a MacBook screen repair. This can be done at ThePhoneLab (if in stock) in as little as 2 hours.
Does your MacBook have vertical stripes or colored bars?
This is a common problem that can manifest itself in different ways. The above example with purple bars is the most common. This well-known problem is known online as “flexgate. This problem does not have to be caused by fall, bump or water damage. The well-known flexgate problem has a different cause: Namely, a display cable in your MacBook that was designed too short. When opening and closing the screen, the display cable rolls up or down. With frequent use, this cable may have cracks in it resulting in the above and below problems. This problem is most common on MacBook Pros from 2016, 2017 or 2018 but has also been seen frequently on new MacBooks, where Apple did start using a longer cable. Unfortunately, the extended warranty program Apple created for this problem is no longer active. Is your MacBook younger than 2 years old? Then this can often be fixed by Apple within warranty.

Is YOUR MacBook having problems with Backlight illumination?
The above spots in the illumination of your screen are often also caused by the aforementioned “flexgate. You often see that this is a beginning of an increasingly worse problem.

Streaks can occur due to impact damage, a faulty display cable, wear and tear or a problem with the graphics chip. Sometimes they occur suddenly for no apparent reason.

Can MacBook screen streaks disappear by themselves?
In most cases, it doesn’t. If streaks remain visible or get worse, there is often a hardware problem that can only be fixed with a repair.

Is a MacBook with screen streaks still safe to use?
Yes, it usually does. But the problem can get worse. Especially with cable problems or incipient backlight damage, prompt inspection is wise to prevent further damage.

How do I know if the screen or motherboard is broken?
Connect an external monitor. If the picture is good there, then the problem is probably in the screen.
