Screen wont come on. But phone comes on.

I was charging my Note 20 Ultra one day and using it at the same time. Literally all of a sudden the screen goes black and nothing on the display. I can hear the Facebook Videos playing and a phone call came through but screen remained black.

Phone was only 2 years old. Never been dropped, always had a protective case and screen protector.. never got wet.

Just wanted to explore options before last resort of getting the screen replaced.

Any help will be appreciated
