Re: Vizio VW42LHDTV10A No power
You have to disconnect the cables from the main board to the power supply board before applying PS_ON signal to the power supply board since we do not want to back feed the signal back the main board. You can use a 1K resistor between 5v and PS_ON pin to turn on the 12v/24v section.
More likely to have bad LDO regulator IC's on the main board.
