LCD Monitor Assembly Service
The 42" LCD Monitor is connected to an LCD Control PCB that provides the signal, power, and
data to the monitor. The monitor is encased in a metal bezel and backbox assembly with a glass
display shield to protect the LCD panel. The Control PCB is mounted to the backbox inside the
cabinet. Power is provided by a dedicated 24 VDC power supply that connects to the Control
PCB and the AC power strip. The sections that follow provide replacement procedures for LCD
Monitor Assembly components. Figure 22 shows an exploded view of monitor assembly.
