Vizio P42 and P50

[Gregg Loewen]

VIZIO P42 Service Menu Access

To enter the factory mode in the VIZIO model #’s P42 / P42e / P42HD / P42HDe,

Hold down the Channel Down (-) button on the front bezel while
switching the Master Rear AC Power switch ON.

This might work for the 50″ as well. Can’t remember what’s actually in there though.

There’s global grayscale RGB in the user menu but my sample couldn’t be calibrated fully with that. The bottom had to be optimized which meant the top was considerably plus blue. Still, it was way better than stock.
