Hello everybody,
A faulty PSU recently came to my possesion and i need some advice on how to revive it, if possible.
It was part of a desktop whose motherboard, vga and hard disk were rendered useless, possibly due to a spike in the supply voltage.
To the point:
When i connect the power supply to a working motherboard and try to turn it on, it seems completely dead. Same thing happens when i connect it to the xilence power supply tester.
Upon opening the case i noticed 2 burnt resistors, 2 damaged ones and 1 burnt transistor (that one actualy fell off it's place when i touched it).
Here, you can see the clearest photos i could take.
The first step of the revival process would be to replace the faulty components (or at least the ones that seem to be faulty). But is there a safe way to replace a resistor, whose value i don't know (for the ones that are completely burnt)?
Also, the code K619 C945 P is written on the transistor, but i can't find it's datasheet, so i can't find a suitable replacement for it.
If there is another way of dealing with this piece of equipment, i would be happy to know.
Thanks!
