Brand new macbook pro screen flickering
Frustrating! A brand new MacBook Pro screen flickering can be a real nuisance. Let's troubleshoot the issue together. Here are some steps to help you resolve the problem:
Hardware Issues:
- Loose Connection: Check if the screen is securely connected to the logic board. Make sure the screws are tightened properly.
- Faulty Screen: It's possible that the screen itself is faulty. Try booting your MacBook Pro in Target Display Mode (TDM) to see if the issue persists. To do this:
- Connect an external display to your MacBook Pro.
- Restart your MacBook Pro.
- Immediately hold down the 'F2' key while booting up.
- Release the 'F2' key when you see the Apple logo.
- Your MacBook Pro's screen should now be mirrored on the external display. If the flickering persists, it might be a screen issue.
- Loose or Faulty Display Cable: The display cable might be loose or damaged. Try gently wiggling the cable while the screen is on to see if the flickering stops.
Software Issues:
- Update macOS: Ensure your MacBook Pro is running the latest version of macOS. Sometimes, software updates can resolve display issues.
- Reset the System Management Controller (SMC): The SMC manages various system functions, including the display. Try resetting it:
- Shut down your MacBook Pro.
- Locate the following keys: 'Shift + Control + Option + Power'.
- Press and hold these keys while powering on your MacBook Pro.
- Release the keys when you hear the boot chime for the second time.
- Disable and Re-enable the Display: Try disabling and re-enabling the display in System Preferences:
- Go to System Preferences > Displays.
- Uncheck the box next to "Show mirroring options in the menu bar when available".
- Wait for a few seconds and then re-check the box.
Additional Troubleshooting Steps:
- Boot in Safe Mode: Boot your MacBook Pro in Safe Mode to isolate the issue:
- Restart your MacBook Pro.
- Immediately hold down the 'Shift' key while booting up.
- Release the 'Shift' key when you see the login screen.
- If the flickering persists in Safe Mode, it's likely a software issue.
- Run a Diagnostic Test: Run a diagnostic test using Apple's built-in tool, Apple Diagnostics:
- Restart your MacBook Pro.
- Immediately hold down the 'D' key while booting up.
- Follow the on-screen instructions to run the diagnostic test.
If none of these steps resolve the issue, it's possible that there's a hardware problem with your MacBook Pro's screen or logic board. In this case, you may need to contact Apple Support or visit an Apple Store for further assistance.
