Reassembly Notes

Caution

∙Be sure to replace the LCD module or other display components with compatible parts. Components may be damaged if compatible parts are not used. See the table on page 2-13.

∙At the lower-right corner of the LCD, reinstall protective tape if it was present on the original LCD.

∙For an OmniBook 4150B, if you install a different type of LCD module, you must set the switches on the VGA PCA according to the type of LCD module. See the table on page 2-13.

∙Install new screws for all screws you remove that hold the display hinges. Otherwise, the hinges could loosen over time.

∙For an LED strip cable that is routed around the bottom-right corner of the LCD, make sure it is routed through the corner of the LCD bracket.

∙Install the inverter PCA under the main LCD flex cable.

∙The extra length of LCD wires connecting to the inverter PCA is folded back along the PCA.

∙Snap in the end caps after the display is assembled.

Caution

At the lower-right corner of the LCD module, be careful the wires are not pinched where they pass next to the LCD bracket. Otherwise, they could be damaged.

Caution

For a 13-inch LCD, make sure the spacers and tape are installed when you assemble the LCD module and LCD shield. Otherwise, LCD quality may be significantly degraded, including noise or discoloration when the display is moved. (Service notes 4100-04, 4100-05.)

Install tape here to hold the cable to the shield.
