Summary: We bought our TV in 11-2011, the picture is great, we love it. September 2012 a blue vertical line showed 3/4 on the right side. Opened a case with Sharp and after a long wait got a replacement delivered. The delivery guys asked if it was a blue line and commented it is common.
Flashlight defect - very noticiable in low light scenes or dark backgrounds

Summary: I just received this TV and although picture quality is excellent in bright scenes and pictures, the quality of dim scenes is very poor due to the flashlight problem. Three corners and a spot on the left side are leaking much more back-light into the picture.
