Trying to fix Vizio E70-E3. +16VS from the power supply is getting to the CPU/motherboard but I am not seeing any output from switching reg IC U201. No power is going to the PW Key switch. The output of U201 is a narrow pulse feeding inductor L201. U201 seems to be in an over current situation and inductor L201 is "singing". The DC output of L201 to the filter caps is very low.
Anyone got an idea what might be causing the DC voltage from U201 to be low? I stole the CPU pic from another post from March for the same TV. I really don't want to buy a used CPU board from eBay....
