No set I see has much more than the one year warranty and the BAD CAPS issue exists in all makers so far.
I can only hope the BAD CAPS debacle is one that folk will ask for longer warranties.
I'm having the same issue with my plasma tv that many are having with their Samsung LCDs. Plasma unit is turning on and off eventually getting various forms of a distorted colored screen. It seems to occur on a cold start-up after the tv has been powered off for a while. I called Samsung and they will not do a goodwill service repair. Rep stated that although there are service alerts with the same problem,however, PN50A550S1FXZA is not on that list. A TV should last beyond three years. I will not buy another samsung tv again.
