Chuwi Lapbook pro Black screen problem

Can someone help mw fix the sudden black screen problem on my Chuwi Lapbook pro.

I just bought my chuwi lapbook pro a month ago. When I opened it this morning it was alright , I was just checking files for my due assignment but suddenly the screen turned all white. I thought it was just the laptop lagging so I simply press the power button then when I turned it on again it gave me all black screen. I literally don’t know what to do. I hope you guys can help me. Thank you in advance!
