By 'Power Good' are you referring to the _FAIL signal? it should be around 5V,if not something is pulling it down.
_FAIL signal feeds into Pin 2 on the Ricoh, Pin 15 on Ramsey and Pin 56 on Gary, if it's not 5V then the Amiga won't initilize. I had a similar issue on an A3000 where someone had replaced a cap with the wrong one (Had a 47uF instead of a 470uF)
There's no cap on this line that I can see so the only other component is R175 which should be a 470 ohm resistor.
First thing to do is chekc you are actually getting 5V from the PSU
