Whilst very happy with my new set I have noticed a very slight ghosting/edge enhancement, most noticeable with text. It is apparent regardless of source and I'm using decent QED and IXOS Scarts. It's pretty slight and isn't apparent from my viewing position - only when closer than 3 feet to the set. Any ideas? The set is only 2 weeks old from John Lewis, so is the best plan of action an engineer visit or a replacement?
