the caplist is useless without diameters.

anyway, moving on - what's wrong with the mosfet?
if it's shorted to the gate pin then the driver circuit will also be damaged.

Looks like the is some more Damage after the mosfet because of shortage. it does not turn on full after replacement.

ist like on /off Swinging.

where or what is the Driver circuit. can you please tell or Show me.

thanks


for the Diameters. normally you don't find the same measures for all anyway. and there is enough space for most.but i could measure some stuff if anyone wants.
 
driver circuit is the parts connected to the gate pin.
download a datasheet to see which pin that is.
 
i will try to see where it goes. no idea where to get this datasheet though.

not much information about this psu
