Hey guys, I have a question for you. I bought a TV from Costco back in February. Yesterday, I turned it on and there's a grey line down the screen (looks like some pixels have gone out). Someone I talked to said I should take it back to Costco and see if they would replace it for me. I have two potential problems. First, it was a store display (the model has been discontinued or something) and second, I can't seem to find the paperwork that we got with the TV. What do you think my odds are of this being successful?
