After reading this article and my Samsung LN4665FX/xaa doing the same exact thing, I called Samsung and discussed with them the symptoms I had. Called Dec. 21st 2010, and they contacted a repair rep. Samsung said the same thing about a Onetime service call, and that if this was not related to the problem then I would be responsible for the call. I'm an engineer myself, so I could have fixed the problem, but for a free call to fix the problem, I'll leave it to the experts. The rep called that night and they came out the next day, replaced both capacitors and the TV turned on without a problem. I asked the tech about how many has he fixed (this problem only) and mentioned that at least 3 a week. Way to go Samsung and step up to the plate on this. I have a feeling that the design engineer on this model tree of TV most likely doesn't work with Samsung anymore, but I've got to believe that his boss was looking to cut cost, and still maintain a product that will outlast its warranty. My TV was bought in 2006 of November, so again, I applaud you Samsung, great job. I will buy your TV again, and again.
