I've just bought the Panasonic TX32PK25, and there's what I consider to be a problem with the picture. On either side of the screen there are areas of shading about three inches wide running from top to bottom. This is only apparent when bright images are displayed, for example on the green of the pitch when watching a football match. Anybody else seen this? I've heard of the same problem on a TX32PG50. Is this a problem or an "un-documented feature" of Panasonic Tau TV's ?
