摘要：A power supply for a video display device (14) includes a protection circuitry (12)
which shutdowns the power supply to prevent damage to the power supply or the
display device (14). The protection circuitry monitors sync pulses generated in the video
display device (14) and disables the power supply switching transistor (Q5) in the absence
of the sync pulses. The protection circuitry (12) is triggered in the event a fault occurs in
the power supply or the video display device (14).
