Hi guys,
got this one wih "not working" status. Checked +5V SB, there was as low as 2,5 V there. Swapped bulged crapxon and also one diode on its input for beefier - the former one measured OK, but was really burned badly from heating, basically all that part is. Than it measured arround 5 V, thats OK.
I tried to fire it up without fan, but got nothing, thought thats protection. But after recapping whole secondary and soldering in fan, I got still the same. Basically it slightly wheezes with no load, that's common for FSP I think. If I ground the green pin, the wheezing gets louder but I get no other voltage than +5V SB.
Measured quickly for short on secondary, there is none and also it does not go into protection mode (no clicking), so I think this is not the problem. So far I haven't changed the small caps, but I think they are hopefully in not so bad condition to prevent it from start with no load. Will swap them later too.
Any ideas what to check next? I have to go now, will shoot some photos later, so far you can grab som frome jonny for example: http://www.jonnyguru.com/modules.php...Story3&reid=84
