The problem of a blurred screen and stripes on Apple laptops may be caused by various factors. Here are some common reasons and corresponding solutions: 1. Common reasons
1. Monitor cable issue: Loose or damaged cables may cause abnormal screen display, resulting in stripes- Poor contact of the disassembly line can prevent normal scanning of the screen and also lead to the appearance of horizontal or vertical stripes.
2. Graphics card malfunction: Graphics card malfunction is one of the common causes of screen display problems, including damaged video memory, incompatible or damaged graphics card drivers, etc.
3. Memory module issue: Poor or damaged memory module contact may also cause abnormal screen display.
4. Operating system or driver issues: - Operating system crashes, obsolescence, or incompatible or damaged drivers can all cause screen display problems.
5. External interference: There is strong magnetic field interference around the monitor, such as electric sparks, high-frequency electromagnetic waves, etc., which may cause stripes on the screen.
6. Hardware aging or damage: LCD screen aging, power circuit output bulging, leakage, insufficient power supply to the driver board circuit, MCU core and main chip virtual soldering, etc. may also cause stripes on the screen. 2、 Solution method
1. Check and reconnect the ribbon cable: - If the laptop supports disassembly, you can try unplugging the ribbon cable again to ensure a secure connection.
2. Restarting the computer: Sometimes a simple restart can solve temporary malfunctions.
3. Enter safe mode: Restart the computer and hold down the Shift key to enter safe mode. Check if it is working properly in safe mode to determine if the problem is caused by a third-party application.
4. Update operating system and drivers: - Ensure that macOS is the latest version and check if graphics card drivers and other updates are also needed. Go to "System Preferences">"Software Updates" to check and install.
5. Reset NVRAM/PRAM: - Turn off the computer and hold down Option+Command+P+R when restarting until you hear a second startup sound to reset certain hardware settings.
6. Run Apple diagnostic tool: - Restart the computer and hold down the D key during startup to enter Apple hardware testing and check for hardware faults.
7. Check external devices: - If there are external monitors or other devices, try unplugging them and observe if the laptop's display is normal.
8. Check the screen surface: Use a soft cloth to gently wipe the screen and check for dirt, water stains, or scratches that may affect the display effect.
9. Contact technical support: If the above steps do not solve the problem, it is recommended to contact Apple's official technical support or go to an authorized service center for maintenance. 3、 Summary
The problem of screen distortion and stripes on Apple laptops may involve multiple aspects, ranging from simple external interference to complex hardware failures. Users can investigate one by one according to the above methods and choose the appropriate solution based on the actual situation. If the problem is complex or difficult to solve, it is recommended to seek the help of professionals.
