Haenk,
As I said, I had a spare, so the PC is repaired.
As I can’t find the schematic , we should do some retrofitting on this part.
What I find very strange is that I have a short circuit between the 5v Standby output connector and the ground. (Test in both directions of the multimeter)
I have removed the capacitors related to this output, none is in short circuit as this video makes think.
If we look on the net some schematic, often this output is actually rectified by a diode output of a mini transformer (I think they call it the driver) So the meter should go in one direction. Strange because this diode is "big enough". I will try to remove it and test this when I have a little time
If you find the schematic, I’m a taker
