8. To prevent the optical surfaces from attracting dust, dirt, and scratches, we
recommend that the backlight replacement be performed in a dust free
environment.
9. Customers replacing the backlight do so at their own risk. Datascope will not
assume any liability, and will not warrant any displays which have been modified
by the customer, including replacement of the backlight, even when the following
procedure is used and all of the necessary precautions have been taken.
Replacing the backlight can cause a lowering of the quality (performance). Even if
the replacement work is performed in accordance with the following procedure,
Datascope can not guarantee the resulting quality.
1. Perform the steps outlined in “Removal of the Passport XG LCD Color Display” on
page 4-4.
2.
Taking care not to scratch the front of the display, place it face down on the flat static
free work surface.
3. Looking at the back of the display, locate the metal backlight holder by following the
high voltage wires to the side of the backlight tube.
4.
Using round tipped tweezers, or an equivalent tool, release the backlight holder by
carefully pressing down on the small plastic tab that latches it in place. See Figure 1,
Detail “A” Side View.
5. Slowly, gently, and in a straight line pull the backlight and holder out of the side of the
display. If the fluorescent lamp was broken inside the display, carefully pull out the
backlight. If pieces of the glass remain inside the display, carefully remove them.
6.
Once the old backlight and holder have been removed, slowly, gently, and in a straight
line push in the new backlight (P/N 0149-00-0009) until the small plastic tab latches it
in place.
7.
Reassembly of the display into the Passport is the reverse of the disassembly.
