Replacement for LNT-4661F

[JR8300]

I've had an all too common issue with my Samsung 4661F for the past year or so. The set decides to turn off and then on again without me pressing a button. After 3-4 replacement main boards Samsung has finally agreed to replace my set with the LN46A750.

I've seen the A650 and 630, but I have never seen the 750 in anyone's home. For anyone on the site that owns this set I have heard numerous reports regarding a cycle in which the TV turns itself on and off in a continuous loop. Has anyone here experienced this issue and how was it rectified?

Also, I have heard numerous issues with the bezel reflecting light, has anyone experienced this issue? With all LCDs uniformity is an issue (I.e. flashlights) again I have heard this is a bigger issue with this set.

Samsung is giving me the option to keep my current set and try another repair or upgrade to this new set. I'm aware the picture increase is substantial but it concerns me that I don't know a single person who owns this TV. Any feedback would be greatly appreciated. Thank you.
