VP0R error

[MDY]

3115 board U5410

pin1 - ground
pin2 - ground
pin3 - 3.3V
pin4 - 12.57V
pin5 - 12.57V
pin6 - 0.04V

I replaced U5410 but still 0V at it.
Board power but will not load OS X and ASD tells there is ppbus error VP0R

pin6 - 0.04V is not ok, right? Not short to ground on this chip.

VP0R is a voltage sensor, U5410 is a current sensor..........

wich board is this???

 

[MDY]

It is 820-3115 board.

ok, check Q5480, corrosion is pretty common....

Will check tomorrow, but what about pin6 - 0.04V on U5410. Should be that 3V?? I have 0.04V

The question here is, are you getting VP0R error or a IO0R error???
