Need to find what caused short PCB

[Modex007]

Hi, i i'm experimenting and looking to fix tacx flow t2241 board. Changed blown parts. Except one mossfet. Connected to power and bang. Two resistors and a fuse was blown. Removed to test big mosfet. I think it's ok. But ordered new one in case. Where to search what could cause short? Tried everything...

Second time was blown R57 and R32
Also F2 1amp fuse
First photos before.

Next ones after blown rezistors but i already replaced them

Tried everything?
Did you check the bridge rectifier?
