Hello, I have a Phillips 42 inch Lcd tv. As soon as i plug it into an outlet it begins clicking. I assume it is trying to cycle on and off. All 12v pins seem to have the correct voltage. right about 12. The one that I did notice that was wrong is the 3v3 st. As the power supply clicks the voltage fluctuates between 0.90v up to 1.5v. It changes almost every time it cycles (clicks) On the (off) cycle it drops all the way to zero and when its cycles on it never goes above 1.5v. It continues doing this as long as I leave it plugged in. I see no visible bad caps. I believe I have isolated the click to a little black box. I will add pic. Any info on where to check next. Thank you in advance.
