Would recommend to run Pre-boot system assessment test to check the LCD functionality. To run the test, hold down the FN key and press the power button which will initiate the test. In case you are able to see the test running on the screen, it means it’s not an issue with the LCD. Color bars on the screen indicate functional LCD.
However, if the screen is dark, then wait for a few minutes, you should hear beep sounds from the computer.
You can refer the Dell Article 266787 on www.support.dell.com
Let me know if you are getting any error messages.
If the external monitor display is fine, then the issue could be with the LCD.
You can try reseating the LCD Cable. If reseating the LCD cable also doesn’t resolve then, would suggest you to replace the LCD screen.
You can also refer to the link for No Display issue:

Please respond for any further assistance.
