Re: Vizio M492i-B2 Won't Turn On
We have to find the BLon signal in order to rule out the main board. Other than that, if the BLon is present, I would look hard on that those LED control IC's.
The BLon would act the same as PSon. Look for a DC voltage that appears when the TV is turned on and disappears when the TV is off.
