LCD Screen not scrolling

Turned on VI purchased Rambo V1.4

Vi logo then 302 bug fix 2 then the main screen

push scroll and the menu screen comes up

from here the scroll does nothing so I cannot make any submenu selections

Just to be sure, you’re turning the knob in the menu, and it’s not moving what is selected?

The turning action is a different set of pins and wires than the click and than the display. So it’s possible it’s a bad wire or a bad connection.

Correct I push to leave the info screen. On the next screen turning, the knob does nothing push returns to info screen

 

Is the knob just spinning on the shaft perhaps?

solved.

It was a bad cable.
