Hi:
I am trying to repair this SMPS, and I see that it powers up (let say for 1-2 secs) and then turns off.
For this short period I see the 12V,5V,3.3V,5Vstby on........along with the Power Good one. Then PG goes off and then the rest do the same.
The chip that decides it is a HY510N.
The voltages that I am reading on the pins are.
V12 - 11.42V
V5 - 4.98V
V3 - 2.57
PGI - 1.15V
Any idea what to look at?
Regards,
Francesc
