After replacing the bulb (Osram) on my 3 year old Samsung HL56A650 and changing the setting in the tech menu to Osram from Philips. I now have a contrast/brightness pulse/shift. It shifts from dynamic to standard or cool to warm (the only way I can describe it) every second. It is very noticable on a still blue or white screen. It is an intermitent problem, lasts for 5 mins sometimes and othertimes it lasts for hours. I've seen other forums expressing this problem but have never seen a solution. Tech guys have been unable to pinpoint the problem. Anyone have the same issue that has been repaired? Thanks

A dust can be on the lamp or color wheel!
