Need help on deciding what capacitors to pull first

[Jeff262]

I have a old board from a claw machine, input is 48vac and motor output should be 48dc then it starts the motor spike ar 48dc and immediately drop to 5v i some its bad capacitor. Where should I start with the larger or smaller ones, what ones normally fail faster? Thanks jeff

Here's very few there anyway - do you have a scope to check the ripple on the capacitors?.

Failing that, I would suspect the largest one for such a major failure.
