1.3 3. Removal and Replacement

This chapter describes how to remove and replace parts of the PS/2

Display. The first part of the chapter covers removal and replacement

procedures for the tilt swivel stands and rear covers of the displays.

The chapter continues with instructions on how to discharge high voltages

in the displays once the rear cover is removed.

This chapter also covers general removal and replacement procedures for

the card tray assemblies, signal cables, and integrated tube components

(ITCs). Included here are references to display-specific information,

where you will find complete details on removing and replacing these

components for each individual display type.

CAUTION:

The display must never be left unattended with the covers removed and

powered on in a customer environment.

Each main part of the display has its own removal procedure, for example,

"Tilt Swivel Stand." Where a step in a specific procedure represents a

complete procedure that is described separately, a reference to that

complete procedure is given. For example:

1. Power off the system (see "Powering Off the System" in topic 1.1.3).

2. Remove the tilt swivel stand (see "Tilt Swivel Stand" in topic 1.3.1).

3. Remove the rear cover (see "Rear Cover" in topic 1.3.3).

The steps show you where you can find the complete instructions for each

procedure.

To replace a part, reverse the removal procedure and observe any

additional replacement instructions.

Always ensure that parts are located correctly and latched into position

(where applicable) before securing.

After removing and replacing any field replacement units (FRUs), the

appropriate alignment procedures must be performed on the display.

Adjustment procedures are presented in "Part II. Display-Specific Service

Information" for each display type.
