Re: Vizio vo420e no 12v
Ok it's U601 ( you have the board, we have a picture). 30Ω seems low, I suspect the fan7530 is bad. and Q101 will also be bad.
The fan7530 has an internal zener and should run at about 12 volts VCC
I would also check the two fets that the fan ic drives, make sure they are not shorted.
Q101 is likely a KST2222a
