Question about Mitsubishi VS-50605 50" Rear Projection Television
Over Current Protection
Pin 1 of IC951 is also the Over Current Protect input.
The internal FET.s ground return is at pin 2 of
the IC. The voltage drop across R955 and R956
indicates the FET.s current, and is coupled through
R953 to pin 1 of the IC. The Over Current Protect
circuit is activated if the voltage at pin 1 of the IC
exceeds 1.35 volts.
Stabilization and rough regulation are provided by
feedback from pin 3 of T951 to pin 1 of the IC. Fine
regulation feedback is from a secondary supply,
through the Photo Coupler, PC951, to pin 1 of IC951.
Its possible that Diode D953 is leaky allowing the voltage to rise on pin 1 of the IC
