BT30V (Tuner SOS) Detect Circuit
D2661
D2663
The BT30V source is generated by a boost regulator circuit that consists of IC2607
and biasing components. The BT30V output is monitored for over-voltage
condition. The diode D2663 goes into conduction when its reverse breakdown
voltage is exceeded. The output of the diode causes Q2626 to turn on and
output a high to trigger the SOS condition.
