=== Issue Description ===
My MacBook Pro is experiencing a persistent black screen issue accompanied by a reboot loop.
When powering on, it plays the usual startup chime, but the ***internal display remains black***. If I shine a flashlight directly onto the screen, I can faintly see a dim Apple logo (***under 1% brightness***), indicating the system is attempting to boot but failing at a very early stage—likely during the hardware self-check, particularly related to the display.
As workaround, I ***unplugged the built-in display cable*** and use an external monitor. Then every thing works fine, I just been using it as desktop for month.
=== ***Repair suggestions*** ===
Apple support suggested replacing the entire display assembly, which is their standard recommendation.
A third-party repair center narrowed it down to a potential LCD component failure and proposed replacing just the display panel.
=== ***Help needed*** ===
However, I’m unsure if the LCD itself is the true root cause.
I need help determining the most likely root cause before committing to an expensive full display replacement. Thanks!!
