Display is not coming

You're not giving us much to go on, so it's going to be difficult to help you.

Do you mean the screen is black? Is there any sound or LEDs indicating the laptop is turning on? Does the charging indicator come on? Have you tried an external monitor? Check with a flashlight up against the screen; if you can make out an image your backlight may have failed.

What have you tried and when did this start? Has there been any damage or liquid exposure?

As you can see, a lot more information will be needed if you really want help. Please elaborate or eventually we'll just archive your question as unanswerable.
