Blank Screen after reinstalling macOS

Hello,

I am experiencing an issue when starting up my 13-inch Retina MacBook Pro (2015 model) running macOS Monterey.

About three weeks ago, I had already posted on the forum about a problem where, when entering my password, the progress bar would remain stuck for hours without moving (MacBook Pro 2015 stuck on startup). Since then, I’ve tried several solutions. First, I used Disk Utility to repair the disk, and then I attempted to reinstall macOS Monterey. However, I encountered an issue where the installation progress bar would get stuck. That problem now seems resolved, but it has been replaced by another: my Mac now displays a black screen with nothing showing on it.

I know the Mac is on because I can interact with it (I can feel that I’m clicking) and I hear the fans when I place my ear close to the device.

I’ve tried several key combinations, such as “Control + Power button” and “Option + Command + Power button.” When I restart, the Apple logo briefly appears with an empty progress bar, then the logo disappears, and the screen remains black.

I’m wondering if anyone has encountered this issue before. At first, I thought it might be related to the display, but since the Apple logo briefly shows and the external display also remains black when connected, this doesn’t seem to be the case.

Thank you in advance for any help or suggestions!
