Re: General PSU Discussion and FAQ contributions
could anyone share a what to do list for repair power suply.. starting from cheking the suspicious broken part...
and now I'm share some of my experience.. in repair PSU
PSU short.... chek rectifier diode... and replace with similar parts
no power but 5vsb..... chek primary power transistor or nfet..do search in replacement data sheet.. and replace it with same similar parts that has similar value in datasheet....
strange sound on psu.... replace primary (biggest one) capacitor.........
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

Re: is it possible to revive dead psu
but how did I read current ratings? I mean is there any meaning on sb**** or mbr******, is there any standard for their code example sbr2100
(just my guess)
sbr = shotkky barrier rectifier
2100 is 100 amps?? or maybe 10 amps??
which one says diode current ratings.
as for the transformer is there any standard for their code too
I mean some trafo code is ERL 33 PSG blah blah blah
(my guess again)
ERL is manufacturer code
33 is current ratings or maybe wattage 330 watt maybe??...Last edited by prongs12; 04-11-2013, 09:53 PM.

Re: is it possible to revive dead psu
yes in some case that was the problem. and to add my headache, is design of second diode brigde.
i mean high speed diodes diode tha has three legde.. the code that show on their is too various.....

is it possible to revive dead psu
hello folks...
okay straight to the question... is possible to revive dead PSU and if possible increasing wattage..
because from my experience in my bussiness I had seen lot of PSU same product line but different wattage had same PCB design...
I had all components that I need. I even success in recapping some blowing caps and some of them works just fine...
thx
