Yes,this kind of defect is covered by manufacturer warranty.
As long there is no cracked LCD panel,panel can be replaced under manufacturer warranty-as long the tv is still under 1 year old.I recommend taking unit to a Best Buy store,they will ship it to nearest Service Center,and it will get fixed in about a week.
No,you could not cause this defect by moving the set,it just happened(is a common issue with all LCD panels)
