I forgot to tell you to uncheck the download manager thing, that's why it is 
downloading .exe.

Anyway, i ran some test today, i unplugged the high voltage driver and found 
out that instead of 10 volts on one output i now have 13-15 volts, which means 
that either it is a bad filter, or the pwm  feedback is bad. On the other hand, 
the 24 volts output remains 17 volts no matter what, which would probably 
indicate either a bad pwm controller or a bad converter.
I figured out the pwm controller and the mosfet for the 24 volts voltage, and i 
will put a scope tomorrow to see what happens, but i was unable to figure out 
where the 10 volts voltage is coming from.

I also found a technical manual for osa 5585, but it is rather ambiguous.
>From it i found out that the input of the power board is on the db15 connector, 
but it seems there are some missing voltages from it. 

But one thing at the time. I have 23.5V on the input which is exactly what is 
written on the power supply. So i must be able to obtain the 10 and 24
