My PLV-30 is 18 months old, and I recently changed my DVD player for a Toshiba 510. Now while watching DVD's I occasionally get a blue screen for a second or two. When the picture re-appears the projector as lost it's widescreen setting. It doesn't happen with every film I watch, and as occurred no more than twice during the same film. Anybody know why this is happening, can it be fixed ?
