    Re: Dell Monitor blinking LED

    The Bl_On Signal turns on Q757,which in turn turns on Q761,and that is the cct that supplies the voltage to the IC. I would suggest that you measure the DC Voltage on R754, before you press the on/off Button and see if it changes when you press the button. C764 I assume you have changed ??,so I would look closely at Q757,Q761, R752 and R754(both 10KΩ)
