Black screen on boot, System32 repair error (SrtTrail.txt), and BitLocker prompt on Surface Laptop 3

am experiencing severe booting and system stability issues with my Surface Laptop 3. Below is a detailed breakdown of the problem: 1. Primary Boot & Display Issue (Standalone Laptop) Upon turning on the laptop, the Surface logo appears normally, but it then goes completely to a black screen without a mouse cursor. The keyboard lights and keys are functional, but Windows fails to load. After leaving the device unplugged for days and attempting more than 15 hard restarts (powering off and on), the laptop occasionally successfully boots to the login screen. Verification / Visual Anomaly: When it successfully reaches the login screen, the clock and the PIN keypad numbers appear completely scrambled/disarranged on the screen. 2. Display & System Repair Issue (When Connected to External TV) When connecting the laptop to an external TV screen via HDMI/DisplayPort, it prompts a BitLocker recovery screen. After entering the BitLocker recovery key, Windows displays a Blue Screen error: "Your PC ran into a problem and couldn't be repaired." The screen provides the following log file path: ⁠C:\WINDOWS\System32\Logfiles\Srt\SrtTrail.txt⁠ along with a "Network connection failed" message. Restarting the device while still connected to the TV sometimes allows it to boot semi-normally. Since this issue has persisted for over two months and prevents normal daily use, please advise on the next steps for repair, system recovery, or hardware replacement.

    The symptoms match a startup/recovery failure on Surface, with an additional BitLocker recovery prompt and display problems. The supported next steps are:

    1. Force a shutdown and restart first
      Press and hold the power button until the Surface shuts down and restarts and the Windows logo appears again, about 20 seconds, then release it.
    2. If the device still does not boot, enter Windows Recovery Environment (WinRE)
      Turn off the device and try to boot it. After two failed boot attempts, Windows should automatically enter WinRE.
    3. From WinRE, open Command Prompt and rebuild boot records
      Go to Choose option > Troubleshoot > Advanced options > Command Prompt.
      If prompted, enter the BitLocker recovery key. Then run these commands in order:
      • bootrec /scanos
      • bootrec /rebuildbcd
      • bootrec /fixmbr
      • bootrec /fixboot
      This is a repair step for Recovery/BCD startup issues.
    4. If Windows starts after that
      Install the latest Surface and Windows updates.
    5. If Windows still does not start, use a USB recovery drive
      Shut down the Surface, insert the USB recovery drive, then press and hold volume-down while pressing and releasing power. When the Surface logo appears, release volume-down.
    6. For the BitLocker prompt after firmware-related changes
      If the Surface continues prompting for the BitLocker recovery key after UEFI or TPM firmware-related changes, one documented workaround is:
      • Boot to Surface UEFI
      • Open Security
      • Select Change Configuration under Secure Boot
      • Select Microsoft Only > OK
      • Select Exit > Restart
      If the device still cannot boot even with the correct BitLocker recovery key, a documented recovery path is to use the BitLocker recovery key together with a Surface recovery image on USB.
    7. For the black screen symptom
      Since the device reaches the Surface logo and then goes black, the basic Windows black-screen steps supported here are:
      • Press Windows + Ctrl + Shift + B to reset the graphics driver
      • Press Windows + P, then P again, then Enter to cycle display modes
      • Press and hold the power button for 20 seconds to force restart
    8. If recovery does not resolve it
      If the Surface still will not start normally after the recovery steps and USB recovery, the documented next step is service. Microsoft indicates that self-repair, a service order, or in-person support may be available.

    Given the two-month duration, repeated failed boots, SrtTrail.txt repair failure, BitLocker recovery behavior, and the scrambled on-screen display when it does boot, the practical path is:

    • run the WinRE bootrec repair first,
    • then use a USB recovery drive / Surface recovery image if boot still fails,
    • then proceed to service or replacement evaluation if recovery does not fix it.

    The pattern of "sometimes boots after many hard restarts" and "boots semi-normally after reconnecting to TV" strongly suggests intermittent hardware failure rather than pure software corruption — a software corruption issue would not fluctuate based on being plugged into an external display or on how many times you power cycle it.

    Step 1 — Force restart and try to reach WinRE

    Hold the power button ~20 seconds to force a shutdown, then power on. If it fails to boot twice in a row, Windows should automatically drop into Windows Recovery Environment (WinRE).

    Step 2 — From WinRE, go straight to the command-line repair (skip the black-screen shortcuts)

    Choose option → Troubleshoot → Advanced options → Command Prompt. If prompted, enter your BitLocker recovery key. Then run, in order:

    bootrec /scanos

    bootrec /rebuildbcd

    bootrec /fixmbr

    bootrec /fixboot

    This is safe — it only rewrites boot records, not your files. Skip the Win+Ctrl+Shift+B / Win+P display shortcuts entirely; those only work once Windows has already loaded in the background, and your black screen happens before that point, so they won't do anything here.

    Step 3 — If Windows starts after that

    Immediately finish your backup if you haven't already, then install the latest Surface and Windows updates.

    Step 4 — If it still won't boot, use a USB recovery drive / Surface recovery image

    Shut down, insert the USB recovery drive, hold volume-down while pressing power, release volume-down when the Surface logo appears. Note: this step can wipe the drive, so only do it after Step 0 backup is done (or accept that you may not get another backup chance).

    Step 5 — If BitLocker keeps reappearing after firmware-related changes

    Boot to Surface UEFI → Security → Change Configuration under Secure Boot → Microsoft Only → OK → Exit/Restart. If it still won't boot even with the correct recovery key, use the BitLocker key together with the Surface recovery image on USB.

    Step 6 — Stop here and go to service

    Given all of the following together — two months of intermittent failure, worsening boot success rate, the SrtTrail.txt automatic-repair failure, and especially the scrambled clock/PIN digits on the lock screen — this combination points to a hardware fault (most likely GPU/display controller or a failing storage module), not something any software repair step will fix. That visual corruption symptom is the deciding factor: no bootrec command or recovery image fixes corrupted on-screen rendering. If Steps 1–5 don't produce a stable boot, don't keep cycling through more troubleshooting — go directly to Microsoft Support / an authorized Surface service center for hardware diagnostics (SMART data, GPU/display controller check) rather than risking your last usable boot window on more recovery attempts.
