What are the main factors that can lead to sudden display shutdowns or errors on the screen?

Main factors that can lead to sudden display shutdowns or errors on the screen in Android devices:

• Hardware issues: damage to the screen, flex cables, display controller, or battery.
• Device overheating: the system may turn off the display to protect itself at high temperatures.
• Driver or firmware errors: software failures controlling the display.
• Incorrect app behavior: for example, apps that cause excessive load on graphics or system resources.
• Power supply problems: unstable power or low battery charge.
• System failures: errors in Android OS leading to reboot or display shutdown.

For diagnostics, it is useful to check logs (logcat), update the system and apps, and also check the hardware components.
