Has anyone ever had success repairing a stuck pixel on a LCD TV? I bought a 32" Panasonic that had been a display TV for $135, but despite having examined it in the store, I only noticed what appeared to be a stuck pixel when I got home. I consider it stuck as opposed to dead as it seems to have a permanent purple shade to it, rather than being perpetually white or black. It might just be an illusion, but it also appears to shift slightly depending on everything around it. I've read many tips online about poking it with a blunt, pointed object or pressing with a paper towel or something, but I'm not sure if such things would actually work or just destroy the TV. I've also heard about some programs that you can run through a connected PC that flash vivid colors on the screen that could somehow unstick the pixel, but would that work through an analog cable?
