Fig. 8 - Setting the LCD contrast
Step 5:
Once the LCD is screwed into place and aligned properly, reinstall the main board
and plug all the cables back into it. Make sure to plug all the cables back into the
board in the proper orientation, including the LCD cable as shown in the photos
on the previous page.
Replace the bottom of the case, but before screwing it all back together, test that
the LCD is properly working and aligned. If the LCD backlight does not light up it
could mean that the side pins are not insulated from the metal edge and you will
need to adjust the LCD and or electrical tape to fix the issue.
Once the LCD is installed and properly working you can adjust the contrast setting
if needed. You can adjust the contrast by pressing the edit button then the system
button and turning the value wheel as needed and or adjust the potentiometer
on the back of the LCD.
Screw everything back together and you are finished.
