If one of the 4 wires is broken you will get similar results so swap the Y stepper with another stepper just to make sure it's the board. If the problem is still with the board then you should just buy a whole new board. It could be many components - the driver itself or any of the capacitors or resistors nearby. Or a bad board etch (not likely).
On a um2 board you have a extra output for a stepper. You could probably remap this extra one to be the y-axis in firmware assuming you don't need dual extrusion....
I think it has been described on this forum before but i'm to lazy too look for it now as I'm on my phone.... so see if you can google it.... otherwise ask again..

I try that, it is not about the motors, something is wrong with the board.

This is exactly what I think but I can not find anything.

Thank you very much.

Quite a number of people had troubles with China cloned mainboards. The only working way out of it I know is the expensive one (buying the genuine Ultimaker board from a reseller).
