4 Replacement Procedure

Assembling PCB-assembly cell

1.

Remove the paper (coated with a mold release) from the double-sided tape in the
three areas on the replacement backlight unit. The areas are at the top and on both
sides. See Figure 4-70.

2.

Turn the backlight on.

3.

Check that the backlight is free of dust, foreign objects, or damage. Perform this
check also for the reverse side of the cell. Then install the cell of the PCB assembly in
the backlight unit.

CAUTION:

Align the top left corner of the cell with the corresponding corner of the

backlight unit, as indicated by

②

in Figure 4-70.

Be careful not to damage the TAB.
