This is an easy fix, you have found a very common problem the next time it will take you only a few minutes to check. If time is money don't get into electronics, but if you are starting to get into electronics/repair, get yourself an Capacitance and ESR meter.
The fuse is a symptom of the fault, not the cause of it, it never really is just the fuse. It's extremely common for components to fail like this. Don't expect a replacement board to be a magic fix all, it can be really advantageous to get a new one or have a working set when taking comparative readings though. A secondhand board always carries a risk of arriving with it's own problem and even introducing further faults.
Most people who want to repair something are too lazy to start checking a few components one by one with their multimeter, so congratulations on that.
Normally when repairers power up a device they use a variac or a dim bulb tester (latter can be made fairly cheaply), these are designed to limit current and reduce the chance of a component failing on first power up after repair. Without these you have to be on your game or else your effort is wasted. The same goes for ordering one of each capacitor, fuse, mosfet, you would normally get a few of each just in case.
