Blank screen v2

[itsmedc93]

I put marlin on the sd card and added it into the ender 3 v2 and all i have now is a blank screen and i cant get it to work. Do i need to replace the motherboard or tue screen board? Nothing i do is working even adding some files to a seperate sd card and putting it into the slot behind the screen. At one point the screen turned orange.

Dear @itsmedc93

Need to refresh the motherboard firmware and display firmware:

1. Refresh the motherboard firmware tutorial: https://www.youtube.com/watch?v=AKIfwPgN0qs&feature=youtu.be
2. Refresh the display firmware tutorial, format the sd card, then copy the display firmware to the sd card, then insert the sd card into the card slot of the display, then the display will automatically refresh the firmware, and the display will display orange That is to refresh successfully https://www.youtube.com/watch?v=Jswzrh2_ekk
