Re: bn44-00604F No Secondary Power

I'm attempting to repair similar schematics Samsung Power Supply (BN44-00750A) , dead with fuse OK
15NM65M Mosfet shorted, replaced with 16N65M (looks very similar)
R107, R108, R113 interrupted , replaced.
I have replaced also 3S111 with same model (is 3S111 similar to 1S311 ??? )
Checked all surrounding components except capacitors...

Powered up, immediately blown fuse and shorted mosfet !!!

Any hints ?

Thanks
