Ender 5 S1 screen Blank

Good afternoon Team, I brought my Ender 5 S1, 1 month ago, build it, did all the levelling, and got 6 perfect prints out over the moon, I then brought sonic Pad,
got totally confused on the setup, what plugs go where etc, so I thought I would start again, formatted the sd card and download the version I was using 1.07, put it after unzipping it on the sd card, plugged it into slot on printer, switch on, after 5 mins screen was still black.

Could anyone tell me what is wrong please…

All the best from Alan
