Last October I bought the Samsung LN-T4671 LCD TV (happens with any xx71 series TV) and after a while noticed some odd behavior with the 120Hz Auto Motion Plus. When set to High, Med or Low it had Triple ball effect (three footballs trailing), Stutter and vapor trails. Samsung was aware of the problem and came out with a firmware update that allowed AMP to be turned off. With AMP off the TV is perfect in picture quality no stutter,TBE or vapor. Samsung said this would nearly fix the issues with AMP on low but it's still there. Also they said they where working on a fix 5 months ago. Now they are saying there is no fix. The reason I bought this TV is for the AMP and paid more money for it. People have had their units replaced /their motherboards and still the issue exists. I have been on the phone to Samsung support many times with no satisfaction at all. Seems to me I paid extra money for something that doesn't work and Samsung is trying to bury their head in the sand. This is not to bash Samsung as they have a huge amount of products out there that work as advertised. What would you do? I want a newer TV that works as advertised.
