LCD2004 Controller menu screens not loading
Posted: Tue Dec 27, 2016 1:35 pm
I have recently assembled a Geeetech I3 Pro B.
When the machine is powered up, or the display reset button is pressed, the 'Info screen' appears normally.
If I press the rotary encoder button, the menu screen showing "info screen', 'Prepare', 'Control' and 'SD card' also appears correctly but if I try to select any of the options by rotating the control knob, the display goes blank.
Pressing the knob again returns to the Info screen but the information is garbled. Pressing the reset button again causes the screen to be displayed correctly again.
I suspect the controller card may be faulty but would like your advice.
