I have a Samsung HCM4216W HDTV that is just over 3 years old. I turned it on tonight and the convergence is completely out of whack. Like someone used the guns as disco lights then just left them all pointing in their own directions. I can't manually adjust the convergence. When I get to that menu and try to move the little crosshairs, nothing happens. This happened when I first bought this tv. I bought a floor model, worked for about 2 weeks then boom, all out of whack. They gave me a brand new one and I didn't have any problems until now. I think I bought the extended 4 year warranty but looking at my receipt it doesn't say how long. It could be 3 or 4 years. I'm hoping it is 4 because the 3 years ran up in Feb. This really blows. I bought this from Soundtrack or as they are known now, Ultimate Electronics. I hope they will come through for me. I can't afford to replace it. So much for those earlier comments about how I don't want to replace a working HDTV that only has component inputs. It should last 10 years! Phoooey, I jinxed it.
