TLA 704 Color Portable Mainframe Service Manual
Use the following procedure to reinstall the flat panel display assembly:
1. Reattach the cable connecting the flat panel display assembly to the interface
board.
2. Reinstall the flat panel display assembly by first inserting the top edge and
then rotating it downward into position. (Be sure the tabs are engaged at the
top of the assembly. Insert the five screws that attach the flat panel display
assembly to the mainframe: two screws at the bottom of the assembly on the
front of the instrument, two screws on the top, and one screw on the left side.
(See Figure 6–4 on page 6–13).
Front Panel Knobs
No tools are needed to remove or replace a front panel knob on the portable
mainframe.
To remove a front panel knob, grasp the knob and pull it straight out from the
front panel.
To reinstall a knob, align the knob to a shaft and push in as far as it will go.
Bottom Cover
Removing the bottom cover should only be necessary to assist you in gaining
access to the bottom of the front panel trim ring, or to replace a flip stand or rear
foot. You may also need to loosen the mounting screws on one side of the
bottom cover to remove or replace either side cover or to remove the power
supply.
You will need a screwdriver with a size T-15 Torx tip (Table 6–1, items 1
and 2, page 6–6) to perform this procedure.
Use the following procedure to remove the bottom cover:
1. Locate the parts to be removed in the locator diagram External parts,
Figure 6–1 on page 6–8.
2. Set the mainframe with the cord-wrap feet on the work surface and the
bottom facing you.
3. Remove the four screws that attach the bottom cover to the mainframe. (See
Figure 6–2 on page 6–10.)
4. Lift bottom cover off.
