Maybe my Bean has LCD issue.
When I turn on Bean and enter GUI, load file to print,
the noise appears on the LCD, and sometimes flashes or turns off.
Please check out the reference video.
So I thought this problem is caused by LCD, I bought brand new LCD from Kudo3D store and replaced it.
But this was not a solution at all.
If the failure is not caused by the LCD, what do you think is the cause?
By the way, when I checked the LCD because the print did not work, I noticed this problem.
I bought the bean about a year ago, and is keeping the box unopened for one year relevant to this problem?
Only the first rook was printed successfully.
