Does anyone else have this problem. I got my HLN4365 from a local retailer here in Orlando & noticed that in the very middle of the screen on both the left & right sides of the screen, there were (for lack of a better word) wavy lines about an inch tall & around 8" long. I though it was in the T.V., but it's on the plastic screen. I notice it best under very bright & light backgrounds, but the best way to see it is to enable you "blue screen" & stand back about a foot. When I push on the screen the lines move a little. I even tried loosening the screws holding the cabinet thinking the cabinet was putting too much pressure on the plastic...which didn't work. I have returned 3 other sets thinking I would get one without this problem & every set seems about the same. I even looked at their floor models & went to about six other stores & every HLN 4365 has these same marks on the screen. I called Sammy cust. service (what a joke) & was basically told that they had never heard of it & there wasn't much I could do. They said that it could be the "anti-glare" coating. What good is anti-glare when it creates marks. Has anyone else seen this & can maybe shed some light for me....help...very frustrated.
