Re: Vizio M50-D1 power supply dual voltage?
I would lookup the spec sheet of the PFC IC to get more info about the PFC section.
For example FAN7529_PFC, as you can see the VCC get the kickstart Voltage for the main rectifier via the resistor, that resistor has to be chosen correctly if it is made to run strictly at no higher than 140V or made to handle from 85 ~ 240VAC.
So look up at the spec sheet of the PFC IC, that may give you a clue.
