Nebula pad won't even start

hi, i have a problem with my nebula pad mount on a creality ender 3 v3 ke.

let’s start with the beginning. few monts ago i had a problem with the printer (an error with temperature) shown on the pad (2501 maybe?). After that creality sent me a new motherboard, i installed it and try to print something. The first time the nebula pad stop working (like it was turned off) after more or less 30 minutes, i reopened the printer, “touch” the cable and it worked again. Two days ago after stop working it never started again, i changed the cable but nothing change. How can i solve it?


Tried to reflash the firmware?

Do you know how can i do it without see the screen? There is another way?

I think notafananymore might be better able to answer that question.

Hi guys, anyone who can solve it?
