You will find you can register at samsung.com, get 3 more months warranty and even out of warranty you call 1-800-SAMSUNG to see what can be done.
It appears you missed out on the prior posts but all I suggest is you register to get your extra 3 months then call in.
My LN40A550P3F tv is having a power problem. I have read about the power supply on these televisions going bad because capacitors on the power supply board have blown. The tv is 14 months old, so I am no longer under warranty. Is Samsung fixing this problem, since I have seen numerous threads about this same issue? Clearly there's a problem here! Help...
