I have a question on my new SD533 that was just delivered a couple of days ago. I am noticing that the center of my screen is brighter than the edges and corners. Does anyone know what might be causing that? It seems to me that the brightness of the picture should be even throughout. You can see it the most when there is a solid colored backgroud as I just noticed on a commercial that displayed a solid blue background and it was pretty evident. I am not trying to nit-pick but I don't have any experience with RPTV's and if this isn't normal then I don't want to get stuck with a lemmon.
