Hello i have this board but don't turn on. Only two leds red solid when I connect de cord power and later led orange 5v stand by. I disconnect all items and put pads SYS_PWR but dead..

I have 3v in front panel with power button and 5v in switch diagled

is it worth spending time? I have seen that these second-hand plates are very cheap.

any ideas? thanks for all !

I can't get a schematic for this model. I have registered in several forums with donations but none have it. I can tell you that I get, for example, 3.3v on the power button and 5,0v in pin 4 of switch button diag

No schematics available for Mac Pro.

Not worth to spend the time.
Just test all interchangeable components, if available.
Is better to buy MLB board; if you suspect the problem resides there.
