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.
