Hi everyone. Imagine my dismay when a week ago the LCD panel went on my Sony 40W4500 which i bought in July 09. The screen was suddenly filled with several 3mm White lines all the way across from right to left. After some argy bargy (sale of goods! reasonable durabilty!) with the retailer (Atlantic Electrics) and then Sony themselves plus a £70 call out charge from a local authorised repairer, I was told that the screen could not be replaced and Sony would replace with a brand new 40EX503. I told the chap to hang fire, quickly researched aforementioned model, saw the blinding reviews on here, called the guy back sharpish, and snapped his hand off. It came today. And I have to say that I'm a bit disappointed. The picture quality on both Sky HD and blu ray falls quite a bit shorter than my 40W4500. There are a myriad of picture settings which Ive messed about with but I just can't get the crispness of definition that I had before. Any tips on settings would be greatly appreciated. I'm thinking that if still not satisfied I may contact Sony again but fear their goodwill may have dissipated. I'm surprised because the EX503 reviews were exceptional, so thinking it may be my ignorance with the settings. I'm no expert. I read what hifi but half if it's lost on me. If it's got 5 stars that's good enough for me. Thanks in advance! Mike Cheers
