No, I have edited my post. You were a little too quick with your reply. :-)

HaHa sorry. I checked the cap right by VDD pin. It seems ok (110nF). I replaced it to test and still nothing.

The resistor right by VDD_G pin measures 2k.

All other resistors are close to the markings value.

I mean these components.

Isn't EC7 (10uf 50V) the VDD capacitor?

The startup resistor is actually a string of 3 resistors (125, 205, 125).

Indeed you are right. I took a closer picture.
The three resistors have the right value.
And the capacitor has 10uf as well.

blauerscharik:
So is it safe to say that this power switch (IC2) is not working properly?

I couldn't find any online to buy...
 
And do I even need it or can I bypass this part of the circuit?
fzabkar:
After you switch of the power, does EC01 retain its 320V voltage? If so, this would suggest that 0B2338SP is not starting.

Is there a short on the 5V or 12V supplies? Is the 15V pin of the motor controller shorted to ground?
