Hi. I've got the Sony Wega KV27-FS13 TV. Over the last few months, I've noticed when I play certain concert DVDs (notably Springsteen Live in NYC and Peter Gabriel Growing Up Live) that there is occasionally a "trail" of the image that I've just seen. For example, I might see an image of Springsteen and his guitar, then it switches to something else; however, while switching between shots, I sometimes will see a darkened "image" of Springsteen and his guitar for maybe half a second or so that seems to be "trailing" off or fading while in transition to the next shot; after that it's completely gone. Is this ghosting? Burn in? Something else? Is it harming my TV? If it's not normal, how do I fix it? BTW, my TV has been calibrated with Avia to the best of my ability. Thanks for your help.
