This amp does not power up. The blue light on the cover and the protect light come on. I've read through a few old posts, seems the problem could be on the pwm board. Probing around with my meter I don't get any odd readings from any devices.
I have zero experience with these amps, anyone have this issue before?

If there is no DC output at any channel when the amp tries to power up, there should be an electrolytic cap close to the opto, replace it.
If you can't find the problem, post the DC voltage on all terminals of the 494.
The 475 service manual is in the infinity folder.
