I've got a Sony XBR-65X930D in the shop with a 8 red blink code with no backlights, no video, no audio. When you press power a white light will briefly stay on (5 seconds) go out and then go into the 8 blink code. Not seeing any image with a flashlight, no Sony logo coming up. I have 5v to the USB but notice the optical turns on and off. 8 blink code says problem with AUDIO and to check IC406, PS401,PS402. I couldn't find a schematic and looked all over for these 3 components and could not find them. Voltages at connector CN900 are: Pin 1(white wire) 3.422
