Hi everyone,

I've encountered the same trouble than maxim10373 while looking for a replacement for the ON5134.
After some research, I've found that BU508AW is a correct replacement for this transistor.
The supply is now repaired using this reference.

To go a bit more deeply in the reparation, I have changed all the aluminium capacitors. One of the 2 ON5134 was shorted, I changed both.
The P16NE06 Mosfet was blasted, replaced by a P16NF06E. Three Zener diode BZX85C12 was shorted too, 2 mounted right after the P16NE06, and one in parralel of a aluminium capacitor.

I've spend too much hours repairing this supply, and hope my post could help someone else.

Thanks for reading,
Eldeil.
