Ok thank you very much, I got carried away by the number inscribed on the plate.
Now I have another problem, the mosfet that controls that ic is short but its series was filed and it only has C2 written, someone knows the mosfet that is or some replacement that works in advance grateful.
 
Good morning Rdiaz I still bother you I found two open zener diodes marked as H5 and on the board it says 15v, I can use 15v zener diodes specifically or well if you have the specific part number it would be ideal to make a complete order to digikey, besides I just want Confirm that the 14-pin controller is the IRS20957s.

Thanks for your help
