First, since you have not checked with another cartridge, is to examine
the corona wires and/or "combs" on the cart. Sometimes the wires break
at one end. Also, toner spills could short it out, I've had that
before. Bent contacts on the cart where it connects the HV to the
printer could also be making bad/no contact.
But, the caps could be it, the symptom where it starts working after
warming up does indicate weak caps.
You might want to order a few HV diodes because a leaky HV diode
could be found if the caps are good.
