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:

  1. Loose Connection: Check if the screen is securely connected to the logic board. Make sure the screws are tightened properly.
  2. 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.
  3. 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:

  1. Update macOS: Ensure your MacBook Pro is running the latest version of macOS. Sometimes, software updates can resolve display issues.
  2. 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.
  3. 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:

  1. 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.
  2. 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.
