This chapter provides removal and replacement assembly procedures for the Compaq TFT450 Flat
Panel Monitor.

1.1 Electrostatic Discharge

A discharge of static electricity from a finger or other conductor may damage system boards or
other electrostatic-sensitive devices. This type of damage may reduce the life expectancy of the
devices.

1.1.1 Preventing Electrostatic Discharge

To prevent electrostatic damage, observe the following precautions:
Avoid hand contact by transporting and storing products in electrostatic-safe containers.
Keep electrostatic-sensitive parts in their containers until they arrive at electrostatic-free
workstations.
Place parts on a grounded surface before removing them from their containers.
Avoid touching pins, leads, or circuitry.
Always be properly grounded when touching an electrostatic-sensitive component or
assembly.

1.1.2 Grounding Methods

There are several methods for grounding. Use one or more of the following methods when handling
or installing electrostatic-sensitive parts.
Use a wrist strap connected by a ground cord to a grounded workstation or computer chassis.
Wrist straps are flexible straps with a minimum of 1 megohm +/- 10 percent resistance in the
ground cords. To provide proper ground, wear the strap snug against the skin.
Use heelstraps, toestraps, or bootstraps at standing workstations. Wear the straps on both feet
when standing on conductive floors or dissipating floor mats.
Use conductive field service tools.
Use a portable field service kit with a folding electrostatic-dissipating work mat.
