Hi Chris, if it's not blowing fuses and you're sure you've got all the capacitors ( low value ones in the primary specifically) then check all the high value resistors on the primary and continuity from reservoir capacitor to switching transistor.
The average SMPSU usually doesn't deviate wildly from the application notes of the switching controller so if there's no specific schematic that might be a lifeline.

I’ve fixed the original one twice before by replacing all the electrolytic caps, this time it’s popped something more critical and refuses to come back to life. So I either need a new PSU or a circuit diagram so I can fault find on the original. I’m in the UK.
