Help to identify PS

[anagy9]

Hi all,

Is anybody known something about this power supply? What I know is:

• There is an ST logo on the board.
• Input: ~240VAC
• Output: 12VDC
• using 1NK60Z and TL431 in TO92 package

There are four component blown out. One of the blown out 3 pin component marking starts by ,F'. The other 3 resistors(?) are unidentifiable. If it is a custom supply, is there any what similar with this what can help me to identify broken parts?. I think the age of it is about 8-10 years.

Thank you!
