I just got my TV back today from the shop. Repairs done on problems with initial delivery. I didn't want them to remove it from my house since they cracked the bezel during the first delivery. This time they broke a chunk of the cabinet off the rear left corner. I now have the tv in my living room and on a white background test pattern I see line of yellow, purple & blue spots in the upper right corner and middle left side. There are three spots in each location, one of each color in mentioned order? Has anyone ever seen this? Can I fix it?
