Asking here as well, because I'm out of options. I bought the Samsung HL61A650C1FXZA last week on Craig's List for a very good price. Now I think I know why. The blue and white colors seem to...pulsate, is really the best word I can use to describe it. Every one second it goes from brighter, to darker, then brighter again, then darker again. All the other colors are just fine, and otherwise the brightness level is fine. But this (essentially) blinking light is driving me crazy.
He said he replaced the bulb just a few months ago, and when I remove the bulb the model number on it matches what the TV says it should be.
I find myself dreading anytime the sky is shown in a TV show, but I know it's going to be a blinking sky. Or any commercials that have a heavy white background.
Any idea what could be the issue here? Is it possible he put in a cheap knockoff bulb that still says Samsung and says the correct model number? I'm at a loss, and Google has been no help. I've found a couple people who had the same issue, but no one ever lists an answer.
Any help would be greatly appreciated.
