Interface Troubleshooting
The Interface PWB provides the service technician with
a convenient test point for many of the peripheral com-
ponents such as the Engine, Lamp Circuit, Fans and
Sensors. It is easily accessible as it is located in the
center of the set, directly in the rear of both the LCD
and DLP models.
Figure 4-2
shows the layout of the Interface for the
LCD, V28 Chassis.
Figure 4-3
shows the layout for
the DLP, V29/30/31 chassis. These layouts are as the
technician is viewing the PWB from the rear of the set.
To save time, use the Symptom/Cause information along
with the Circuit Block Diagrams to make checks on the
Interface PWB first.
