Inspiron 14 7460, 2 amber 7 white blinking LED, and auto shutdown

My laptop shows the LEDs on startup as 2 amber 7 times white and then shuts down.
I know from the LED signs that it is a display related error and have tried solutions on the Web but no improvement.
If I connect it to an external display, the display works fine, but I am having trouble with it shutting down on its own after the LEDs blinking.

I would like to know if there is a way to prevent it from shutting down on its own.
