Okay, so here's my story. I brought this LG model on Saturday, returned it on Tuesday, and the problem is still persisitng. Having contacted LG, they have told me to factory reset, done software updates, turned the TV on and off consistently, turned off picture enhancements etc...i have tried it all but it's not working. Now the actual problem is this: When I watch something I get these lines on the TV. It happens most on Blu-ray, but sometimes Sky. It seems when the camera moves on the footage I'm watching you get these lines, like the picture hasn't caught up properly. Also, you get these little pixels around the picture. Now these lines aren't all the time, and they are transparent. They only come and go during sudden action scenes (not intense action sequences) and during white scenes they are more visible. I've tried loads of Blu-rays, DVDs; so it's not the source. This problem is with the LG 47LN578V. If I haven't explained properly, please tell me or ask me questions; i apologise. Does anyone know or can help me, please! I would be forever grateful.
