Required Equipment

Small Phillips screwdriver.

Pointed knife or probe.

Removal Procedure

1.Unplug the ac adapter, if present, and remove the battery.

2.Remove the display assembly and strip cover from the unit (page 2-11).

3.On the display bezel, remove the upper and lower screw covers (using a pointed knife or probe), then remove the six screws.

4.At the bottom of the display, lift up the inner edge of the bezel near both hinges until it unsnaps— be careful to keep the end caps. Then at one side of the display, use your fingers to gently pull the display bezel outward, toward the edge of the case, until the snaps release. When one side is free, repeat along the opposite side—until only the top edge is attached.

5.Now lift the bottom edge about 5 cm and press inward along the top edge until the snaps release and the bezel lifts off.

6.Remove the two screws holding the LCD brackets and hinges near the bottom corners of the display case. Remove the combined hinges and strip cover.

7.On the plastic cable holder, unsnap the cover.

8.If present, unplug the flex cable that wraps around the inverter PCA to the left of the cable holder.

9.Unplug the three cables from the inverter PCA—raise the PCA out of the case, if necessary. Remove the PCA.

10.Slide the LCD module and brackets toward the bottom of the case. When the slots in the brackets clear the tabs in the case, lift out the LCD module—the LED strip cable is still in the display case.

11.If the LED strip cable is held by the LCD bracket, place the LCD module next to the display case and LED strip.

12.Remove the four screws holding the brackets to the LCD module.

13.Separate the LCD module and the shield:

You may have to remove one or more pieces of tape.

If the flex cable is still attached to the LCD module, unplug the cable.
