LC-65D64U No Power/ No Standby Light

[mak2290]

I was able to grab a Sharp Aquos 65" LCD i am trying resurrect. This unit has a power board (MPF3930) and a sub power board (MPF3931). The AC plugs into the MPF3930. AC is 122 volts in. I am first checking for standby power. All the voltage I can read is DC voltage from PP3, which is on the MPF3030 top middle of the screen. I get varying voltage on PP3 from 2.0 VDC to 2.5VDC. I am assuming this would be the standby power. Am i correct? I believe this should be a constant 5VDC. I am assuming if this is the standby voltage, it is too low. I do not see any bad caps and the diodes seem to be ok. Any thoughts... Am i totally off. I have not been able to find the voltage for the pins on the power boards anywhere online. Thanks

Check the voltage on D0251 cathode, on the power supply board, that should be the standby voltage
