disconnected the screen from the laptop motherboard for a long time, but now when I reconnect the screen, it doesn't display anything. However, when checked, the motherboard detects the presence of the screen and functions like sleep mode still work.

Welcome to the forums, newcomer!

If the laptop's screen was disconnected, were you operating the laptop off of an external display? If so, then while hooked to the external display, run DDU and remove all GPU drivers in Safe Mode. Once removed, power down and disconnect from the external display and make sure the connection to the internal display is full seated. Now would be a good time to inspect both ends of the display connector for any dirt/debris.
