The first thing to do is see if the power transformer is good.
Disconnect the Red/Green/Red wires. (label them) This is the 400 volt winding.
Disconnect the Orange/Orange winding. This is the 40 volt winding.
I would try to get a Volt ac reading off of each winding.
Red(1) to Green. Red(2) to Green. And Red to Red.
Any Red to Green will be half the voltage of Red to Red.
If that checks out, move on to the Orange/ Orange winding.(35-40 Vac)
If that checks out, leave them disconnected & do the test points on the Blue (16 volt) winding.
If all of that checks then we find where it got toasted.
