Well before you dismantled it ....I was going to say check input voltage ( around 230 AC ) ....and output voltage ( 13.8 DC ) ....re-solder the 4 pins and see what happens

Yes.
Get that bridge resoldered, those 4 pins are in a shocking state.
I'd also get some of the others checked over but that looks like the culprit to me.
A soldering iron, some solder wick to clean off then reapply some fresh solder to it and it will probably be OK.
Do 1 pin at a time, you dont want to do all 4 at once or it may fall out.
It is possible that the transitor next to it (on the heatsink) has a short and is faulty, but one step at a time.
