G. Under Voltage Protection
When the line input voltage is below 75~85Vac range, the DC voltage on R983 which through R981, R982 is below
4.3V. Then Q981, Q982 turn on, the U901 pin3 immediately be lower at 0.2V and shut down the U901 and power.
H. Degaussing CKT
The DEGU signal which comes from u-p to control degauss coil act or not. When DEGU is high, Q950 will be saturated
to make RL901 working, AC line provides a degaussing current to degauss coil.
