so bad diode(s) on the D pin will overload it.

so bad diode(s) on the D pin will overload it.

So what is the solution?

is only swapping TOP264GW
or only finding and swapping bad diod
or both of them

where is the D pin?

i found diode-like component that was short.
i think that was a resistor. 0,2 ohm

please help..
