Hi...
I'm attempting my first ever SMPS repair and I'm testing a cap that would give me the symptoms I'm getting if it was faulty.
I have one of those cheap 'TC1' component testers that tells me the 1000uF cap is 941uF but has a zero ohm ESR (removed from the board).
Do I believe that ESR reading ? Is the cap shorted ? How do I confirm whether it's good or not if I can't trust the component tester ?
Many thanks !
