They didn't perform the work because they don't really work to assist customers, basically they are like the insurance department who tries to find a way NOT to cover your claim. They never got close to the TV, they just blamed it on finger damage. That is the entire reason I reached out on this site, to get a technical arguement for them to return without costing me $69. It's a scam, they proclaim that the customer did the damage and if you want a 2nd opinion they will charge you $69 to tell you the same thing. I appreciate that you ruled out the East-West idea... here are 3 more that tech sites and customers have identified. In the case of the Bad Tab Bonds, users actually reported that replacing them resolved the horizontal line issues and that a warped front can cause the Black Circles (I believe they said crystal leaks or something). My head is spinning right now from all the things I have read and honestly I am heartbroken. I can't afford to replace an expensive TV like this. The problem is getting worse. I would appreciate any help you can provide. I am convinced that Samsung and Brandsmart are not going to be helpful at this point.
2) The frame of the TV is warped or worn which will cause the circle like spots around the edges.
3) Sounds like the plastic piece in front of the display is warped and pressing into the panel.
4) Bad TAB bonds to the LCD panel itself.(horizontal lines in middle of TV).itself.
