Step 2:
You will need to remove all of the screws from the bottom of the case in order to
open it up. Once all of the screws are removed, remove the bottom cover and set
it aside.
The photo above shows the inside of the JX-305. The main board must be
removed in order to replace the LCD. To remove the main board you need to
remove the 2 screws on the top of the board and also the 7 screws from the back
of the case. You will also need to unplug the cables connected to the main board.
Be sure to make note of the orientation of the cables so that you can reassemble
it correctly when you finish the installation of the LCD.

Step 3:
Now you need to remove the original LCD, it is held in place by 4 small phillips
head screws at each corner of the LCD as shown in the Figure 4 photo.
Once the LCD has been removed you will then need to cover the metal edge by
wrapping it with electrical tape. The electrical tape is used in order to insulate the
metal frame from the LCD. See the photo above where the black electrical tape
has been applied on the metal frame edge on the right side of the metal
mounting frame.

Fig. 6 - Replacement LCD installed using 2 screws
Step 4:
Once the electrical tape is placed around the metal edge to provide insulation, the
replacement LCD can be installed. The replacement has mounting dimensions
that differ from the original LCD. In turn it does not have the same footprint as
the original. Mount the LCD using only 2 of the screws on the right side where the
electrical tape is. The other 2 screws are not used since the left side does not align
with the mounting holes. The 2 screws are sufficient enough to secure the LCD in
place.
Be sure to align the LCD properly before completely securing it in place.
Avoid over tightening the screws.

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.
