I tried the thing of taking a damp washcloth and pressing the pixel with a ball-point pen tip through the washcloth, holding pressure, and turning the TV on. That didn't work.
Also, I tried using software from the internet that rapidly changes colors over the stuck pixels. Supposedly to flash it rapidly 60 times a second for a long time, that is suppose to unstick the pixel. That didn't work either.
If you google for it, you will see that in most cases those things don't work. Basically, if the pixel is stuck, it is stuck that way forever.
I realize Vizio has a zero bright pixel guarantee. I'm sure if I call them they will offer to send a new set. However, since I have gone through 4 sets already (2 with stuck pixels, one with bad speaker hum, and one with a cracked bezel) I have pretty much lost faith in Vizio. So back to Costco I go for my money back.
