I have read everything about Vizios on this forum and I'm still not sure if I have the common U33 issue or not.
Tv starts up and shuts down with remote or button on the TV. Yellow Vizio logo when power cord is plugged in and it turns white when the TV is turned on and stays white.
It has most of the voltagages correct except the PS_ON which is low(2.13V).
I have measured all the common U components and they all seem OK except across U9 between pin 1 & 2 I have 1.5V, not 1.25V as on the others.
Could it be a problem? If I measure from the gnd it looks OK though. 3.31v in and 1.5V out.
Fuses are all OK, I have checked on the T-con too.
Inverter board is the one which PainBill said that it's famous on going bad, sorry I don't have the model number with me right now, but it's a single long board on the left side of the TV. 24V it's going to this board also.
