My Vizio VX32L HDTV10A is no longer turning on. The logo is amber and power switch does nothing. I have the cover off and verified that the 5 VDC is present. The PWR switch does not make it to the PSON on J1 Pin 1. Anyone know the path of this signal or what the common failure part is? I have also verified that 3.3 VDC is present.
