Last time I checked is was a 5V6. Which version (serial number) do you have?

I have SMPS400A180 ,0413A3054_1333

Thanks you

R24 is a 10k 0603, D43 is indeed a 5v6. R24 is connected to D43, if you put in a 12V zener, that could be the cause.

Now i put zenner 12v and all its okay, work.
Thank you.

D43 is marked 6Z and in catalog of smd marking, this code is zenner 12volts, not 5v6.

Best regards.

What if it is marked Z9 instead of 6Z... (PDZ5.6B)

You're reading it upside down. Compare with A6 (BAS316). Cathode is at the top.
