Provided all circuits function within a Power Supply, there are only (3 or 4)
requirements for the Power Supply to function
1. AC Line input voltage: This voltage will be rectified and provide the DC
for the Switching Circuits.
2. Standby Voltage: This voltage is needed to power the Micon.
3. Power On signal from Micon: The micon receives the Power on signal
from the Remote or Front Panel. It will then send the “Power On” Signal to
the Power Supply circuits. This always turns on a relay that activates the
Main Power Circuits.
4. Main AC line voltage switch must be closed: In some units, primarily
HDILA models, there is a switch that controls the AC line voltage. In
HDILA models, this switch is the Temperature Sensor that is mounted
above the lamp. In other models this may be a Main Power switch on the
back of the unit. This switch must be closed before the Television may be
powered on.
