Re: Fortron FSP300-60ATV repair

Voltages seemd to be ok i guess. Just a little difference. I tried the o-scope, but i have to say that i don't understand anything about what it means.

I will add the pictures if you can say something about those =)







I changed the resistor R32 to 1,5 ohms, but decided about the smell that it is too small =) Voltages got little bit better. 12v was 12,2 and so on.

And the operating system is win 7 64 bit. I think i'll try clean install with win 8 and if it doesn't...

Re: Fortron FSP300-60ATV repair

Ok. I still have two symptoms. PC is running 100 cpu all the time. It could be the operating system, but its quite clean install.

Also i'm having errors occasionally when booting that the vga power cable must be connected even it is.

So.... Was the resistor wrong or is there something else on PSU that is broken?

Re: Fortron FSP300-60ATV repair

I have FSP350-60PN which stopped working after long time of no using it at all.

Several condensators were broken. One was totally dead even it wasn't pulled out at all.

There was also one resistor which looked like it had been little too warm, but i think it was R32 not R31. It was 7,9 Ohms and what was left of the colors, we decided it was 15 ohm resistor.

I decided to write this down here even its an old thread if someone someday needs the info
