Hello Everyone,
In one of power supplies what I want to repair 2 resistors has been burnt.
This was the original fault causing 12V being missing on the output.
I have replaced them and there was no low resistance to ground but they have burnt again.



I have checked/measured all components and there was not any odd readings indicating failure.
Resistors are on 12V output monitoring the value. Has anyone had the same problem please ?
I hope someone can point me to the right direction.
Thanking you in advance.
Regards,
Rafal
