| I have this situation.
A 17" monitor mesures arround 400V at the main capacitor of the power supply.
A 14" monitor onlu mesures arround 300V.
Why are the mesures so diferent once the monitor base is the sabe before the capacitor....
AC 230V -> AC to DC rectifier bridge -> DC at the capacitor.
Best Regards.

I have seen this a number of times and can only put it down to some sort of resonance between mains filter components.
