I suggest you start with the electrolytic capacitors at the DC/DC converter.
If you have a circuit diagram look for shorts on the various power
distribution traces. If you do have a short, it will probably turn out to be
an electrolytic capacitor. The capacitors in the DC/DC converter do not have
to be shorted to cause a problem.
