Display panel does not work

I just bought Ender 3 V3 printer. I assembled and connected wires. I turned power on and the display panel does not work. Is this product defective?

Hi!

Is your issue still unsolved? First run of the printer may take a while. If you are still having problem with running a new printer maybe you should try to contact the after sales support. You can email them or use chat - Creality Aftersales

Have a nice day!
