So I'm starting a new topic to update my old one. Check out the whole story on my original issue. After finally getting a new fly back for my mac plus the fast ticking never changed. I checked the voltages on the caps and sure enough the flyback still is not getting enough power. So what I did was first heat up the caps to see if any of the 33 and 22uf caps are bad.
