Need Help On hd tv for watching sports

I would appreciate any Recommendation on a Hd tv that can display sports.I have Purchased Two tv so far with no success. First purchase was a 60" pana st50 Plasma the picture was great and all sports looked smouth with no motion blur or double image/ghosting but after two months it had major image retantion burn in due to me watching sports with statinary logo. I was lucky to have the store take back the tv and give me store credit. So my second purchase is 60" sharp led LC-60LE847U with 240 hz well after having this tv for a week and messing around with the setting I am getting double image/ghosting on any fast moving football,golf ball,and hockey pucs. I will be returning this tv back soon. I watch allot of sports and really want to stay away from any plasma due to IR is there a lcd led tv That matches the motion smotheness of a plasma?? Please let me know.

Thanks

Mike

I Try all motion setting and least amount of blur comes when I turn off motion compensation, but still have judder.

Comcast is the provider. My 6yr old sharp lcd does not have this issue but the new 240hz does, the tv is going back this saturday. Probable will try sami led 7500 series

Pick up a sumsung a 60 led es7500. Very happy with picture and sports games look flawless. This tv is a keeper!!

Thanks
