hi, after 3 years of using F5, today morning it just gone dead. Only lights from Ethernet cable is on. i opened the box but F5 is a single board unlike F3, which have separate power card. Have anyone repaired such things before or do anyone have a circuit diagram for F5?
PS - i did tried changing the 220 uF cap (first in line) but still dead. so need circuit diagram to look into detail.
