However https://www.google.com/search?q=BP68-0633A found only your posts so I'm guessing the BP68 is something else other than a TV.
My Samsung BP68-0633A which is 6 or 7 years old ( i think) has the "White Dot" Problem. I am looking for a DLP chip as I have read that this the fix. Does anyone know if they still make these? I am having a trouble finding anything online.
