8. Inverter Protective circuit for back light and power source circuity
This unit operates on an output voltage of 12V from AC adapter. When an AC adapter with an output voltage
over 12V higher is connected, the control signal from I101 is forcibly connected to the LOW level through
D101 (RLZ18B), Q101 (SST33904), and R101, R102. In order to protect the inverter for back light. By this
treatment, oscillation is suspended in the inverter circuit. It must be noted that the back light it unlit as a result
of the stoppage of inverter oscillation.
