I have a 65" mitsubishi, and after 2 weeks, the red convergence got real bad... When I would turn the TV on, in the upper right corner the red would be 3" off to the bottom. After being on for 40 minutes or so, it would creep back to normal.
I called the store, and the guy says, "did you open up the TV and bang on the guns at all (they call the projection units 'guns')"? I said, "Uh, this a brand new tv, so no, i didn't bang on the guns."
He tells me that's that I need to do, and I said, "No thanks."
He comes out, opens it up, and with the back of his screwdriver starts hitting everything and anything in the TV with a fair amount of force. Nothing fixed it.
He said, "well, we will have to order a new board for it. It will be about 4 weeks."
I told him to talk to the store when the part comes in, because that's where the TV will be. I went to the store, and they replaced it for me... Not only that, but I noticed the TV was on sale, so I got it pricematched to themselves
