I just received a power supply which I ordered from here a few days ago (excellent speed, I might add).

I did all the replacement seemingly well, everything looks as it did before.

But when I turned it on, it turned off again instantly. So I went back and did the LED tests (first the second light didn't come on at all, and I thought that I had somehow killed the logic board) but then it just does the coming on half a second and going off.

This is a "brand new" refurbished power supply, any ideas?

Thanks,

Norbi
