lcd sony kdl-40bx425 the LED flashes twice and does not light

very good night companions, I annoy you if you can give me a hand I have a lcd tv sony kdl-40x425 in which to turn it on it goes from red to green light but immediately goes to red and blinks 2 times, well this is why I was finding out is a short at the source, well I tell you, I only have 5volts and nothing else, filters, resistance diodes, they look and measure well just like the mosfet / what I found that the capacitor c930 when measuring it is short When raising it from the plate it measures me well but in the plate the short one continues to raise the ssc9512s and the short one is no longer found, my question is whether it may be that the ic902 shortens me said capacitor and does not let the source start, from there thank you very much No título.png [191.86kb]

Measure the pin of the integrated and ground, pin 8. The integrated is the soul there.It may be short that pin.I commented that the source is working, if not, it would not turn on the pilot LED.
