First run - LCD all black squares
Hello Prusa community! I completed my printer build this weekend and after turning it on, the LCD comes up with only black squares. I'm looking for advice on what to try next.
What I have tried so far (as suggested in https://help.prusa3d.com/ja/article/lcd-screen-not-working_5256 )
* Verified the cable ribbons are correctly placed on both sides (EXP1=P1 with 1 stripe ribbon, EXP2=P2 with 2 stripe ribbon)
* Released the ribbon cables from all zip ties and and flattened to verify no damage
* Flashed the firmware to latest
I've seen some references to switching the ribbons https://forum.prusa3d.com/forum/original-prusa-i3-mk3s-mk3-prusa-i3-kit-archive/lcd-screen-powers-on-but-only-shows-2-rows-of-black-squares/ . I've also seen some references to turning the ribbons 180 degrees on one side. Are those suggestions still solutions that come up?
Does anyone have suggestions about what to try next to get the LCD working?
Much appreciated!
RE: First run - LCD all black squares
Nevermind. This seems to have resolved itself overnight (magic!). I just went to try a full system reset, and when I powered it on (before doing anything else), the LCD was suddenly working today (it was not last night...).
