Re: Vizio VO37L power problem
OK, I will marked those designators per your numbers. In the mean time I will wait for those sectioned pictures from you, it is good that at least we know the input pins of U15, 17, 19 are connected together, just need to find out if there is open circuit on the ferrite bead (L??) some where on the board.
BTW, when you take the pictures, please move the caps of the way so I can see U22.
Also look close around the input pin of the IC to see if the L?? connected to those input pins show high resistance, those L should have <1 Ohms resistance.
