Good morning all
I recently bought the skr1.3 motherboard and I have the screen of my tronxy x5s a reprapd1scount smart controller the LCD-12864
unfortunately when i upload the marlin file by following step by step the bigtreetech video. I still have a blue screen. I almost try everything I don't know what to do help me please
none of the previous posts have solved my problem and I am really new to programming

It is most probably that the plugs on the back of the LCD are rotated 180 degrees from "standard".

You have to modify things so you can plug in each cable rotated 180 degrees.

I personally carefully pry off the plastic shroud on the back of the LCD cable connectors. Others cut a second key the on the other side.
Or you can cut off the key on the cable, or make up a special cable...

it's a good idea I applied your suggestion but nothing helps
