LCD screen button Will Not Scroll

[Demech]

Hi everybody!

I am facing the same issue with my printer!
Can i have a solution or a correct firmware because my encoder is not scrolling even if the push button works.

Thank you in advance.

might check the pads on the LCD panel, see if there's bad soldering or short out there:

or the pins of the mainchip, related to the SD card and knob function here:

Thank you for your reply.

I have checked LCD pads and board pins but everything seems ok.
Any other suggestion?

no short out or bad soldering? that's weird...then you can download the firmware here see if it works:
