The FET is: CEP73A3G

It was very easy to install. Just cut the original FET:s connectors and then solder the FET away (It's soldered to the board from it's back). Solder 2 cm wires to the original FETs connection points (2) and one 2cm wire to the area where the original FET was fixed to the board. Solder two wires to the new FET in same order as the original. The third wire goes to the center connector. Then put some sticky tape behind the new FET and attach it in some good place. I put mine just onto the main circuit
Is it the first or the second one in the photo?

Just now I unsoldered number 1, but there was no third connection
And the left little connector came off... now nothing is working anymore, even when I soldered everything back together.... umpffff... I know why I don't like that complicated electronic stuff
so for now I think I'll need a new PCB board... or how can I attach the left connector to the board again?
