I have a Ledger Nano S that is having problems on the screen... because when plugged into the cable it only shows a few dots on the screen, maybe the screen is problematic.
When I want to know what the pin is what makes it difficult is to open the Ledger Nano S, even having seen the disassembly tutorial on youtube it still fails.

BTW op, open up your ledger and check how many pins it has — there are two versions 12 pins and 15 pins, buy replacement screen accordingly.
So do you think the Nano S has 12 or 15 pins?
Because I still have trouble unpacking the Nano S until now.
