So, my samsung TV which is only 2 years old has started taking a 'long' time to turn on. While turning on, there is a clicking sound from the area of the tv where the power supply board would be. Seems everyone who has this TV has this same problem after 6 months to a year after the warranty expires. Turns out Samsung used capacitors rated for 10V on a board that runs 12V! A guaranteed failure after at least a year of use. So, i called them and they said they could give me a one time free servicing for the capacitors. I guess if you want to avoid the bad press of a recall, offer a one time free service to replace the bad part.
Anyway, everyone stay away from Samsung TV's.
