Re: hi there need some help to trace parts on vs550 corsair cpu



Thanks for the great tip I will do it, as for the zener diode all of them are 4148 zener should I just use that? Not too sure what u meant by referring to the reference circuit...

Re: hi there need some help to trace parts on vs550 corsair cpu



ok you are right , after googling online by typing "vs550 tny177pn" found the results.. thank you so much!...

my friend gave me this psu (corsair VS550) for free , since the technician quoted him around 45usd he would rather buy a brand new unit, which I decided to take from him and attempt to repair it , then charge him whatever I spent on replacement parts otherwise I keep it but when I open it there are 2 missing parts , one power ic chip (7pins) and one zener diode located zd1 can anyone tell me what those parts are?
sorry for my poor English from Malaysia here.
truly appreciate if someone could help thanks...
