ok tks! I got a bit chicken after 2 went smoked up!
The one with metal casing I could see the TO220 type transistor inside broke up. Hope I still could ID the transistor type to repair it...
Btw is there any standard schematic for SMPS? I know some most used MOSFET, but the plastic casing type could not adjust the voltage.
