Workng on a RCA Colortrak AC/DC manufactured in 1998 that had a bad DC-DC converter . I managed to get that working again and every thing seemed fine when working with DC but when I applied the mains AC , a RIFA X2 PME 285 MB exploded and the 2.5A fuse stayed intact . Voltages looked correct before the incident .
I've heard a lot about RIFA caps being a problem or is this just exaggeration ? Or should I be looking for another probable cause?
