Replacing The Lcd - Fluke 87 IV Series Service Manual

Replacing the LCD

If you need to replace the LCD, you will find it easier to leave the LCD assembly
attached to the circuit board and access the LCD by removing the LCD mask from the
front of the LCD assembly.
1. Remove the circuit board as described under "Removing and Reinserting the Circuit
Board Assembly."
2. Carefully insert the tip of a thin screwdriver under the LCD mask at the top of the
display as shown in Figure 1.
3. Lift up the LCD mask gently with the screwdriver blade to loosen the mask from the
assembly. Be careful to press upward, not inward toward the LCD. By hand, tilt the
LCD mask upward to release.
4. Replace the LCD. The LCD must be centered on the platform between the brackets
before you replace the LCD mask. If the LCD is improperly aligned, the display may
show missing segments or meaningless readings.
5. Reattach the LCD mask by pressing it over the LCD until it snaps into place.
